Expat XML Parser

- -

Expat is a library, written in C, for parsing XML documents. It's the -underlying XML parser for the open source Mozilla project, perl's -XML::Parser, and other open-source XML parsers.

- -

This library is the creation of James Clark, who's also given us -groff (an nroff look-alike), Jade (an implemention of ISO's DSSSL stylesheet -language for SGML), XP (a Java XML parser package), XT (a Java XSL engine). -James was also the technical lead on the XML Working Group at W3 that produced -the XML specification.

- -

This is free software, licensed under the -MIT/X Consortium license. You may download it from -the expat homepage on Source Forge. -

- -

The bulk of this document was originally commissioned as an article by -XML.com. They graciously allowed me to retain -copyright and to distribute it with expat. - -

Overview

-

Expat is a stream-oriented parser. You register callback (or handler) -functions with -the parser and then start feeding it the document. -As the parser recognizes parts of -the document, it will call the appropriate handler for that part (if you've -registered one.) The document is fed to the parser in pieces, so you can -start parsing before you have all the document. This also allows you to -parse really huge documents that won't fit into memory.

- -

Expat can be intimidating due to the many kinds of handlers and options -you can set. But you only need to learn four functions in order to do 90% -of what you'll want to do with it:

- -
- -
XML_ParserCreate
-
Create a new parser object.
- -
XML_SetElementHandler
-
Set handlers for start and end tags.
- -
XML_SetCharacterDataHandler
-
Set handler for text.
- -
XML_Parse
-
Pass a buffer full of document to the parser
-
- -

These functions and others are described in the -reference part of this document. The reference -section also describes in detail the parameters passed to the different -types of handlers. - -

Let's look at a very simple example program that only uses 3 of the above -functions (it doesn't need to set a character handler.) The program -outline.c -prints an element outline, indenting child elements to distinguish them from -the parent element that contains them. The start handler does all the work. -It prints two indenting spaces for every level of ancestor elements, then -it prints the element and attribute information. Finally it increments the -global Depth variable. - -

-
-int Depth;
-
-void
-start(void *data, const char *el, const char **attr) {
-  int i;
-
-  for (i = 0; i < Depth; i++)
-    printf("  ");
-
-  printf("%s", el);
-
-  for (i = 0; attr[i]; i += 2) {
-    printf(" %s='%s'", attr[i], attr[i + 1]);
-  }
-
-  printf("\n");
-  Depth++;
-}  /* End of start handler */
-
-
- -

The end tag simply does the bookkeeping work of decrementing the Depth. -

-
-void
-end(void *data, const char *el) {
-  Depth--;
-}  /* End of end handler */
-
-
- -

After creating the parser, the main program just has the job of -shoveling the document to the parser so that it can do its work. - -


-

Building and Installing expat

-

The expat distribution comes as a compressed (with GNU gzip) tar file. -You may download the latest version from -Source Forge. -After unpacking this, cd into the directory. Then follow either the -Win32 directions or Unix directions below.

- -

Building under Win32

-

If you're using the GNU compiler under cygwin, follow the Unix directions -in the next section. Otherwise if you have Microsoft's Developer Studio -installed, then from Windows Explorer double-click on "expat.dsp" in the -lib directory and build and install in the usual manner.

- -

Alternatively, you may download the win32 binary package that contains -the expat.h include file and a pre-built dll.

- -

Building under Unix (or GNU)

-

First you'll need to run the configure shell script in order to configure -the Makefiles and headers for your system.

- -

If you're happy with all the defaults that configure picks for you, -and you have permission on your system to install into /usr/local, you can -install expat with this sequence of commands:

- -
-   ./configure
-   make
-   make install
-
- -

There are some options that you can provide to this script, but the -only one we'll mention here is the --prefix option. You can -find out all the options available by running configure with just the ---help option. -

- -By default, the configure script sets things up so that the library gets -installed in /usr/local/lib and the associated header file in -/usr/local/include. -But if you were to give the option, --prefix=/home/me/mystuff, -then the library and header would get installed in -/home/me/mystuff/lib and /home/me/mystuff/include -respectively. -

- -
-

Using Expat

-

Compiling and Linking against expat

-

Unless you installed expat in a location not expected by your compiler -and linker, all you have to do to use expat in your programs is to include -the expat header (#include <expat.h>) in your files that -make calls to it and to tell the linker -that it needs to link against the expat library. On Unix systems, this would -be the -lexpat argument. -Otherwise, you'll need to tell the compiler where to look for the expat header -and the linker where to find the expat library. You may also need to take -steps to tell the operating system where to find this libary at run time. -

-

On a Unix based system, here's what a Makefile might look like when expat -is installed in a standard location:

- -
-
-CC=cc
-LDFLAGS=
-LIBS= -lexpat
-xmlapp: xmlapp.o
-        $(CC) $(LDFLAGS) -o xmlapp xmlapp.o $(LIBS)
-
-
- -

If you installed expat in, say, /home/me/mystuff, then -the Makefile would look like this:

- -
-
-CC=cc
-CFLAGS= -I/home/me/mystuff/include
-LDFLAGS=
-LIBS= -L/home/me/mystuff/lib -lexpat
-xmlapp: xmlapp.o
-        $(CC) $(LDFLAGS) -o xmlapp xmlapp.o $(LIBS)
-
-
- -

You'd also have to set the environment variable LD_LIBRARY_PATH -to /home/me/mystuff/lib (or to -${LD_LIBRARY_PATH}:/home/me/mystuff/lib if LD_LIBRARY_PATH -already has some directories in it) in order to run your application. -

- -

Expat Basics

-

As we saw in the example in the overview, the first step in parsing an -XML document with expat is to create a parser object. There are -three functions in the expat API for creating a -parser object. -However, only two of these -(XML_ParserCreate and -XML_ParserCreateNS) -can be used for constructing a parser for a top-level document. -The object returned by these functions is an opaque pointer -(i.e. expat.h declares it as void *) to data with further internal structure. -In order to free the memory associated with this object you must call -XML_ParserFree. Note that if -you have provided any user data that gets stored -in the parser, then your application is responsible for freeing it prior to -calling XML_ParserFree. -

- -

The objects returned by the parser creation functions are good for -parsing only one XML document or external parsed entity. If your application -needs to parse many XML documents, then it needs to create a parser object -for each one. The best way to deal with this is to create a higher level -object that contains all the default initialization you want for your parser -objects. - -

Walking through a document hierarchy with a stream oriented parser will -require a good stack mechanism in order to keep track of current context. -For instance, to answer the simple question, -"What element does this text belong to?" requires a stack, since the -parser may have descended into other elements that are children of the -current one and has encountered this text on the way out. - -

The things you're likely to want to keep on a stack are the currently -opened element and it's attributes. You push this information onto the -stack in the start handler and you pop it off in the end handler. - -

For some tasks, it is sufficient to just keep information on what the -depth of the stack is (or would be if you had one.) The outline program shown -above presents one example. Another such task would be skipping over a -complete element. When you see the start tag for the element you want to -skip, you set a skip flag and record the depth at which the element started. -When the end tag handler encounters the same depth, the skipped element has -ended and the flag may be cleared. If you follow the convention that the -root element starts at 1, then you can use the same variable for skip flag -and skip depth. - -

-
-void
-init_info(Parseinfo *info) {
-  info->skip = 0;
-  info->depth = 1;
-  /* Other initializations here */
-}  /* End of init_info */
-
-void
-rawstart(void *data, const char *el, const char **attr) {
-  Parseinfo *inf = (Parseinfo *) data;
-
-  if (! inf->skip) {
-    if (should_skip(inf, el, attr)) {
-      inf->skip = inf->depth;
-    }
-    else
-      start(inf, el, attr);     /* This does rest of start handling */
-  }
-
-  inf->depth++;
-}  /* End of rawstart */
-
-void
-rawend(void *data, const char *el) {
-  Parseinfo *inf = (Parseinfo *) data;
-
-  inf->depth--;
-
-  if (! inf->skip)
-    end(inf, el);              /* This does rest of end handling */
-
-  if (inf->skip == inf->depth)
-    inf->skip = 0;
-}  /* End rawend */
-
-
-
- -

Notice in the above example the difference in how depth is manipulated -in the start and end handlers. The end tag handler should be the mirror -image of the start tag handler. This is necessary to properly model -containment. Since, in the start tag handler, we -incremented depth after the main body of start tag code, then in -the end handler, we need to manipulate it before the main body. -If we'd decided to increment it first thing in the start handler, then -we'd have had to decrement it last thing in the end handler. - -

Communicating between handlers

- -

In order to be able to pass information between different handlers -without using globals, you'll need to define a data structure to hold -the shared variables. You can then tell expat (with the XML_SetUserData -function) to pass a pointer to this -structure to the handlers. This is typically the first argument received -by most handlers. - -

Namespace Processing

- -

When the parser is created using the XML_ParserCreateNS, -function, expat performs namespace processing. Under namespace processing, -expat consumes xmlns and xmlns:... attributes, -which declare namespaces for the scope of the element in which they -occur. This means that your start handler will not see these attributes. -Your application can still be informed of these declarations by setting -namespace declaration handlers with - -XML_SetNamespaceDeclHandler. - -

Element type and attribute names that belong to a given namespace are -passed to the appropriate handler in expanded form. By default this expanded -form is a concatenation of the namespace URI, the separator character (which -is the 2nd argument to XML_ParserCreateNS), and the local -name (i.e. the part after the colon). Names with undeclared prefixes are -passed through to the handlers unchanged, with the prefix and colon still -attached. Unprefixed attribute names are never expanded, and unprefixed -element names are only expanded when they are in the scope of a default -namespace. - -

However if XML_SetReturnNSTriplet -has been called with a non-zero do_nst parameter, then the -expanded form for names with an explicit prefix is a concatenation of: -URI, separator, local name, separator, prefix. -

- -

You can set handlers for the start of a namespace declaration and for -the end of a scope of a declaration with the -XML_SetNamespaceDeclHandler function. -The StartNamespaceDeclHandler is called prior to the start tag handler -and the EndNamespaceDeclHandler is called before the corresponding end tag -that ends the namespace's scope. -The namespace start handler gets passed the prefix and URI for the namespace. -For a default namespace declaration (xmlns='...'), the prefix will be null. -The URI will be null for the case where the default namespace is being unset. -The namespace end handler just gets the prefix for the closing scope. - -

These handlers are called for each declaration. So if, for instance, a -start tag had three namespace declarations, then the StartNamespaceDeclHandler -would be called three times before the start tag handler is called, once for -each declaration. - -

The namespace.c example demonstrates the -use of these features. Like outline.c, it produces an outline, but -in addition it annotates when a namespace scope starts and when it ends. -This example also demonstrates use of application user data. - -

Character Encodings

- -

While XML is based on Unicode, and every XML processor is required to -recognized UTF-8 and UTF-16 (1 and 2 byte encodings of Unicode), other -encodings may be declared in XML documents or entities. For the main -document, an XML declaration may contain an encoding declaration: -

-<?xml version="1.0" encoding="ISO-8859-2"?>
-
- -

External parsed entities may begin with a text declaration, which -looks like an XML declaration with just an encoding declaration: -

-<?xml encoding="Big5"?>
-
- -

With expat, you may also specify an encoding at the time of creating a -parser. This is useful when the encoding information may come from a source -outside the document itself (like a higher level protocol.) - -

There are four built-in encodings in expat: -

    -
  • UTF-8 -
  • UTF-16 -
  • ISO-8859-1 -
  • US-ASCII -
- -

Anything else discovered in an encoding declaration or in the -protocol encoding specified in the parser constructor, triggers a call -to the UnknownEncodingHandler. This handler gets passed -the encoding name and a pointer to an XML_Encoding data -structure. Your handler must fill in this structure and return 1 if -it knows how to deal with the encoding. Otherwise the handler should -return 0. -The handler also gets passed a pointer to an -optional application data structure that you may indicate when you set -the handler. - -

Expat places restrictions on character encodings that it can support -by filling in the XML_Encoding structure. -include file: -

    -
  1. Every ASCII character that can appear in a well-formed XML document -must be represented by a single byte, and that byte must correspond to -it's ASCII encoding (except for the characters $@\^'{}~)
  2. -
  3. Characters must be encoded in 4 bytes or less.
  4. -
  5. All characters encoded must have Unicode scalar values less than or -equal to 65535 (0xFFFF)This does not apply to the built-in support -for UTF-16 and UTF-8
  6. -
  7. No character may be encoded by more that one distinct sequence of -bytes
  8. -
- -

XML_Encoding contains an array of integers that correspond -to the 1st byte of an encoding sequence. If the value in the array for a -byte is zero or positive, then the byte is a single byte encoding that -encodes the Unicode scalar value contained in the array. A -1 in this array -indicates a malformed byte. If the value is --2, -3, or -4, then the byte is the beginning of a 2, 3, or 4 byte sequence -respectively. Multi-byte sequences are sent to the convert function pointed -at in the XML_Encoding structure. This function should return -the Unicode scalar value for the sequence or -1 if the sequence is malformed. - -

One pitfall that novice expat users are likely to fall into is that -although expat may accept input in various encodings, the strings that it -passes to the handlers are always encoded in UTF-8. Your application is -responsible for any translation of these strings into other encodings. - -

Handling External Entity References

- -

Expat does not read or parse external entities directly. Note that any -external DTD is a special case of an external entity. -If you've set no ExternalEntityRefHandler, then external -entity references are silently ignored. Otherwise, it calls your handler with -the information needed to read and parse the external entity. - -

Your handler -isn't actually responsible for parsing the entity, but it is responsible -for creating a subsidiary parser with -XML_ExternalEntityParserCreate that will do the job. This returns -an instance of XML_Parser that has handlers and other data -structures initialized from the parent parser. You may then use -XML_Parse or XML_ParseBuffer calls against this -parser. -Since external entities my refer to other external entities, your handler -should be prepared to be called recursively. - -

Parsing DTDs

-

In order to parse parameter entities, before starting the parse, you must -call XML_SetParamEntityParsing with one of the following -arguments: -

-
XML_PARAM_ENTITY_PARSING_NEVER
-
Don't parse parameter entities or the external subset
-
XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE
-
Parse parameter entites and the external subset unless -standalone was set to "yes" in the XML declaration.
-
XML_PARAM_ENTITY_PARSING_ALWAYS
-
Always parse parameter entities and the external subset
-
- -

In order to read an external DTD, you also have to set an -external entity reference handler as described above. - -

Expat Reference

- -

Parser Creation

- - -
-Construct a new parser. If encoding is non-null, it specifies a -character encoding to use for the document. This overrides the document -encoding declaration. There are four built-in encodings: -
    -
  • US-ASCII -
  • UTF-8 -
  • UTF-16 -
  • ISO-8859-1 -
-Any other value will invoke a call to the UnknownEncodingHandler. -
- - -
-Constructs a new parser that has namespace processing in effect. Namespace -expanded element names and attribute names are returned as a concatenation -of the namespace URI, sep, and the local part of the name. This -means that you should pick a character for sep that can't be -part of a legal URI.
- - -
-

Construct a new parser using the suite of memory handling functions -specified in ms. If ms is NULL, then use the -standard set of memory management functions. If sep is -non NULL, then namespace processing is enabled in the created parser -and the character pointed at by sep is used as the separator between -the namespace URI and the local part of the name

-
-typedef struct {
-  void *(*malloc_fcn)(size_t size);
-  void *(*realloc_fcn)(void *ptr, size_t size);
-  void (*free_fcn)(void *ptr);
-} XML_Memory_Handling_Suite;
-
-
- - -
-Construct a new XML_Parser object for parsing an external general -entity. Context is the context argument passed in a call to a -ExternalEntityRefHandler. Other state information such as handlers, user data, -namespace processing is inherited from the parser passed as the 1st -argument. So you shouldn't need to call any of the behavior changing -functions on this parser (unless you want it to act differently than the -parent parser.) -
- - -
-Free memory used by the parser. Your application is responsible for -freeing any memory associated with UserData. -
- -

Parsing

- - - -
-Parse some more of the document. The string s is a buffer -containing part (or perhaps all) of the document. The number of bytes of s -that are part of the document is indicated by len. This means -that s doesn't have to be null terminated. It also means that -if len is larger than the number of bytes in the block of -memory that s points at, then a memory fault is likely. The -isFinal parameter informs the parser that this is the last -piece of the document. Frequently, the last piece is empty (i.e. -len is zero.) -If a parse error occurred, it returns 0. Otherwise it returns a non-zero -value. -
- - -
-This is just like XML_Parse, except in this case expat provides the buffer. -By obtaining the buffer from expat with the XML_GetBuffer -function, the application can avoid double copying of the input. -
- - -
-Obtain a buffer of size len to read a piece of the document -into. A NULL value is returned if expat can't allocate enough memory for -this buffer. This has to be called prior to every call to -XML_ParseBuffer. A typical use would look like this: - -
-
-for (;;) {
-  int bytes_read;
-  void *buff = XML_GetBuffer(p, BUFF_SIZE);
-  if (buff == NULL) {
-    /* handle error */
-  }
-
-  bytes_read = read(docfd, buff, BUFF_SIZE);
-  if (bytes_read < 0) {
-    /* handle error */
-  }
-
-  if (! XML_ParseBuffer(p, bytes_read, bytes_read == 0)) {
-    /* handle parse error */
-  }
-
-  if (bytes_read == 0)
-    break;
-}  
-
-
-
- -

Handler Setting

-

Although handlers are typically set prior to parsing and left alone, an -application may choose to set or change the handler for a parsing event -while the parse is in progress. For instance, your application may choose -to ignore all text not descended from a para element. One -way it could do this is to set the character handler when a para start tag -is seen, and unset it for the corresponding end tag. - -

A handler may be unset by providing a NULL pointer to the -appropriate handler setter. None of the handler setting functions have -a return value. - -

Your handlers will be receiving strings in arrays of type -XML_Char. This type is defined in expat.h as char * -and contains bytes encoding UTF-8. -Note that you'll receive them in this form independent of the original -encoding of the document.

- -
- -
-typedef void
-(*XML_StartElementHandler)(void *userData,
-                           const XML_Char *name,
-                           const XML_Char **atts);
-
-

Set handler for start (and empty) tags. Attributes are passed to the start -handler as a pointer to a vector of char pointers. Each attribute seen in -a start (or empty) tag occupies 2 consecutive places in this vector: the -attribute name followed by the attribute value. These pairs are terminated -by a null pointer.

-

Note that an empty tag generates a call to both start and end handlers -(in that order).

-
- -
- -
-typedef void
-(*XML_EndElementHandler)(void *userData,
-                         const XML_Char *name);
-
-

Set handler for end (and empty) tags. As noted above, an empty tag -generates a call to both start and end handlers.

-
- - - -

Set a text handler. The string your handler receives -is NOT zero terminated. You have to use the length argument -to deal with the end of the string. A single block of contiguous text -free of markup may still result in a sequence of calls to this handler. -In other words, if you're searching for a pattern in the text, it may -be split across calls to this handler.

-
-

Sets a handler for any characters in the document which wouldn't -otherwise be handled. This includes both data for which no handlers can be -set (like some kinds of DTD declarations) and data which could be reported -but which currently has no handler set. Note that a contiguous piece of -data that is destined to be reported to the default handler may actually -be reported over several calls to the handler. Setting the handler with -this call has the side effect of turning off expansion of references -to internally defined general entities. Instead these references are -passed to the default handler.

-                                const XML_Char *publicId);
-
-

Set an external entity reference handler. This handler is also -called for processing an external DTD subset if parameter entity parsing -is in effect. (See -XML_SetParamEntityParsing.)

- - -

The base parameter is the base to use for relative system identifiers. -It is set by XML_SetBase and may be null. The -public id parameter is the public id given in the entity declaration and -may be null. The system id is the system identifier specified in the entity -declaration and is never null.

- -

There are a couple of ways in which this handler differs from others. -First, this handler returns an integer. A non-zero value should be returned -for successful handling of the external entity reference. Returning a zero -indicates failure, and causes the calling parser to return -an XML_ERROR_EXTERNAL_ENTITY_HANDLING error.

- -

Second, instead of having userData as its first argument, it receives the -parser that encountered the entity reference. This, along with the context -parameter, may be used as arguments to a call to -XML_ExternalEntityParserCreate. -Using the returned parser, the body of the external entity can be recursively -parsed.

- -

Since this handler may be called recursively, it should not be saving -information into global or static variables.

-
-

Set a handler to deal with encodings other than the -built in set. If the handler knows how -to deal with an encoding with the given name, it should fill in the info -data structure and return 1. Otherwise it should return 0.

- -
-    typedef struct {

-      int (*convert)(void *data, const char *s);
-      void (*release)(void *data);
-    } XML_Encoding;
-
- -

The map array contains information for every possible possible leading -byte in a byte sequence. If the corresponding value is >= 0, then it's -a single byte sequence and the byte encodes that Unicode value. If the -value is -1, then that byte is invalid as the initial byte in a sequence. -If the value is -n, where n is an integer > 1, then n is the number of -bytes in the sequence and the actual conversion is accomplished by a -call to the function pointed at by convert. This function may return -1 -if the sequence itself is invalid. The convert pointer may be null if -there are only single byte codes. The data parameter passed to the convert -function is the data pointer from XML_Encoding. The string s is NOT -null terminated and points at the sequence of bytes to be converted.

- -

The function pointed at by release is called by the parser when it is -finished with the encoding. It may be null.

-
-

Sets a handler that is called for XML declarations and also for -text declarations discovered in external entities. The way to distinguish -is that the version parameter will be NULL for text -declarations. The encoding parameter may be NULL for -an XML declaration. The standalone argument will contain --1, 0, or 1 indicating respectively that there was no standalone parameter in -the declaration, that it was given as no, or that it was given as yes.

-
-

Sets a handler for element declarations in a DTD. The handler gets called -with the name of the element in the declaration and a pointer to a structure -that contains the element model. It is the application's responsibility to -free this data structure.

- -

The model argument is the root of a tree of -XML_Content nodes. If type equals -XML_CTYPE_EMPTY or XML_CTYPE_ANY, then -quant will be XML_CQUANT_NONE, and the other fields -will be zero or NULL. -If type is XML_CTYPE_MIXED, then quant -will be XML_CQUANT_NONE or XML_CQUANT_REP and -numchildren will contain the number of elements that are allowed -to be mixed in and children points to an array of -XML_Content structures that will all have type XML_CTYPE_NAME -with no quantification. -Only the root node can be type XML_CTYPE_EMPTY, XML_CTYPE_ANY, or XML_CTYPE_MIXED.

- -

For type XML_CTYPE_NAME, the name field points -to the name and the numchildren and children fields -will be zero and NULL. The quant field will indicate any -quantifiers placed on the name.

- -

Types XML_CTYPE_CHOICE and XML_CTYPE_SEQ -indicate a choice or sequence respectively. The numchildren -field indicates how many nodes in the choice or sequence and -children points to the nodes.

-

Set a handler for attlist declarations in the DTD. This handler is called -for each attribute. So a single attlist declaration with multiple -attributes declared will generate multiple calls to this handler. The -elname parameter returns the name of the element for which the -attribute is being declared. The attribute name is in the attname -parameter. The attribute type is in the att_type parameter. -It is the string representing the type in the declaration with whitespace -removed.

- -

The dflt parameter holds the default value. It will -be NULL in the case of "#IMPLIED" or "#REQUIRED" attributes. You can -distinguish these two cases by checking the isrequired -parameter, which will be true in the case of "#REQUIRED" attributes. -Attributes which are "#FIXED" will have also have a true -isrequired, but they will have the non-NULL fixed value in the -dflt parameter. -

Sets a handler that will be called for all entity declarations. -The is_parameter_entity argument will be non-zero in the case -of parameter entities and zero otherwise. -

-

For internal entities (<!ENTITY foo "bar">), -value will be non-NULL and systemId, -publicId, and notationName will all be NULL. -The value string is not NULL terminated; the length is provided in -the value_length parameter. Do not use value_length -to test for internal entities, since it is legal to have zero-length -values. Instead check for whether or not value is NULL.

Set a handler that is called if the document is not "standalone". -This happens when there is an external subset or a reference to a parameter -entity, but does not have standalone set to "yes" in an XML declaration. -If this handler returns 0, then the parser will throw an -XML_ERROR_NOT_STANDALONE error.

Parse position and error reporting functions

-

These are the functions you'll want to call when the parse functions -return 0 (i.e. a parse error has ocurred), although the position reporting -functions are useful outside of errors. The position reported is the byte -position (in the original document or entity encoding) of the first of the -sequence of characters that generated the current event (or the error that -caused the parse functions to return 0.)

-

The position reporting functions are accurate only outside of the DTD. -In other words, they usually return bogus information when called from within -a DTD declaration handler.

- - -
-Return what type of error has occurred. -
- - -
-Return a string describing the error corresponding to code. -The code should be one of the enums that can be returned from -XML_GetErrorCode. -
- - -
-Return the byte offset of the position. -
- - -
-Return the line number of the position. -
- - -
-Return the offset, from the beginning of the current line, of -the position. -
- - -
-Return the number of bytes in the current event. Returns 0 if the event is -inside a reference to an internal entity. -
- - -
-

Returns the parser's input buffer, sets the integer pointed at by -offset to the offset within this buffer of the current -parse position, and set the integer pointed at by size -to the size of the returned buffer.

-

This should only be called from within a handler during an active -parse and the returned buffer should only be referred to from within -the handler that made the call. This input buffer contains the untranslated -bytes of the input.

-

Only a limited amount of context is kept, so if the event triggering -a call spans over a very large amount of input, the actual parse position -may be before the beginning of the buffer.

-
- -

Miscellaneous functions

-

The functions in this section either obtain state information from the -parser or can be used to dynamicly set parser options. - -

-
-This sets the user data pointer that gets passed to handlers. -It overwrites any previous value for this pointer. Note that the -application is responsible for freeing the memory associated with -userData when it is finished with the parser. So if -you call this when there's already a pointer there, and you haven't -freed the memory associated with it, then you've probably just leaked -memory. -
- - -
-This returns the user data pointer that gets passed to handlers. -It is actually implemented as a macro. -
- - -
-After this is called, handlers receive the parser in the -userData argument. The userData information can still be obtained using -the XML_GetUserData function. -
- - -
-Set the base to be used for resolving relative URIs in system identifiers. -The return value is 0 if there's no memory to store base, otherwise it's -non-zero. -
- - -
-Return the base for resolving relative URIs. -
- - -
-When attributes are reported to the start handler in the atts vector, -attributes that were explicitly set in the element occur before any -attributes that receive their value from default information in an -ATTLIST declaration. This function returns the number of attributes that -were explicitly set times two, thus giving the offset in the atts -array passed to the start tag handler of the first attribute set -due to defaults. It supplies information for the last call to a start -handler. If called inside a start handler, then that means the current call. -
- - -
-Returns the index of the ID attribute passed in the atts array -in the last call to XML_StartElementHandler, or -1 if there is no ID -attribute. If called inside a start handler, then that means the current call. -
- - -
-Set the encoding to be used by the parser. It is equivalent to -passing a non-null encoding argument to the parser creation functions. -It must not be called after XML_Parser or XML_ParseBuffer have been -called on the given parser. -
- - -
-This enables parsing of parameter entities, including the external -parameter entity that is the external DTD subset, according to -code. -The choices for code are: -
    -
  • XML_PARAM_ENTITY_PARSING_NEVER -
  • XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE -
  • XML_PARAM_ENTITY_PARSING_ALWAYS -
-
- - -
-

-This function only has an effect when using a parser created with -XML_ParserCreateNS, i.e. when namespace -processing is in effect. The do_nst sets whether or not prefixes -are returned with names qualified with a namespace prefix. If this function -is called with do_nst non-zero, then afterwards namespace -qualified names (that is qualified with a prefix as opposed to belonging -to a default namespace) are returned as a triplet with the three parts -separated by the namespace separator specified when the parser was created. -The order of returned parts is URI, local name, and prefix.

-

If do_nst is zero, then namespaces are reported in the -default manner, URI then local_name separated by the namespace separator.

-
- - -
-Return the library version string (e.g. "expat_1.95.1"). - -

See -ARCHIVE LOCATIONS below to find out where to obtain the FAQ article. - -If you want to understand how the JPEG code works, we suggest reading one or -more of the REFERENCES, then looking at the documentation files (in roughly -the order listed) before diving into the code. - - -OVERVIEW -======== - -This package contains C software to implement JPEG image compression and -decompression. JPEG (pronounced "jay-peg") is a standardized compression -method for full-color and gray-scale images. JPEG is intended for compressing -"real-world" scenes; line drawings, cartoons and other non-realistic images -are not its strong suit. JPEG is lossy, meaning that the output image is not -exactly identical to the input image. Hence you must not use JPEG if you -have to have identical output bits. However, on typical photographic images, -very good compression levels can be obtained with no visible change, and -remarkably high compression levels are possible if you can tolerate a -low-quality image. For more details, see the references, or just experiment -with various compression settings. - -This software implements JPEG baseline, extended-sequential, and progressive -compression processes. Provision is made for supporting all variants of these -processes, although some uncommon parameter settings aren't implemented yet. -For legal reasons, we are not distributing code for the arithmetic-coding -variants of JPEG; see LEGAL ISSUES. We have made no provision for supporting -the hierarchical or lossless processes defined in the standard. - -We provide a set of library routines for reading and writing JPEG image files, -plus two sample applications "cjpeg" and "djpeg", which use the library to -perform conversion between JPEG and some other popular image file formats. -The library is intended to be reused in other applications. - -In order to support file conversion and viewing software, we have included -considerable functionality beyond the bare JPEG coding/decoding capability; -for example, the color quantization modules are not strictly part of JPEG -decoding, but they are essential for output to colormapped file formats or -colormapped displays. These extra functions can be compiled out of the -library if not required for a particular application. We have also included -"jpegtran", a utility for lossless transcoding between different JPEG -processes, and "rdjpgcom" and "wrjpgcom", two simple applications for -inserting and extracting textual comments in JFIF files. - -The emphasis in designing this software has been on achieving portability and -flexibility, while also making it fast enough to be useful. In particular, -the software is not intended to be read as a tutorial on JPEG. (See the -REFERENCES section for introductory material.) Rather, it is intended to -be reliable, portable, industrial-strength code. We do not claim to have -achieved that goal in every aspect of the software, but we strive for it. - -We welcome the use of this software as a component of commercial products. -No royalty is required, but we do ask for an acknowledgement in product -documentation, as described under LEGAL ISSUES. - - -LEGAL ISSUES -============ - -In plain English: - -1.

However, since ansi2knr.c is not needed as part -of any program generated from the IJG code, this does not limit you more than -the foregoing paragraphs do. - -The Unix configuration script "configure" was produced with GNU Autoconf. -It is copyright by the Free Software Foundation but is freely distributable. -The same holds for its supporting scripts (config.guess, config.sub, -ltconfig, ltmain.sh). Another support script, install-sh, is copyright -by M.I.T. but is also freely distributable. - -It appears that the arithmetic coding option of the JPEG spec is covered by -patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot -legally be used without obtaining one or more licenses. For this reason, -support for arithmetic coding has been removed from the free JPEG software. -(Since arithmetic coding provides only a marginal gain over the unpatented -Huffman mode, it is unlikely that very many implementations will support it.) -So far as we are aware, there are no patent restrictions on the remaining -code. - -The IJG distribution formerly included code to read and write GIF files. -To avoid entanglement with the Unisys LZW patent, GIF reading support has -been removed altogether, and the GIF writer has been simplified to produce -"uncompressed GIFs". This technique does not use the LZW algorithm; the -resulting GIF files are larger than usual, but are readable by all standard -GIF decoders. - -We are required to state that - "The Graphics Interchange Format(c) is the Copyright property of - CompuServe Incorporated.

"The JPEG Still Picture Compression Standard", - Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44. -(Adjacent articles in that issue discuss MPEG motion picture compression, -applications of JPEG, and related topics.) If you don't have the CACM issue -handy, a PostScript file containing a revised version of Wallace's article is -available at ftp://ftp.uu.net/graphics/jpeg/wallace.ps.gz. The file (actually -a preprint for an article that appeared in IEEE Trans. Consumer Electronics) -omits the sample images that appeared in CACM, but it includes corrections -and some added material. Note: the Wallace article is copyright ACM and IEEE, -and it may not be used for commercial purposes. - -A somewhat less technical, more leisurely introduction to JPEG can be found in -"The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by -M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1. This book provides -good explanations and example C code for a multitude of compression methods -including JPEG. It is an excellent source if you are comfortable reading C -code but don't know much about data compression in general. The book's JPEG -sample code is far from industrial-strength, but when you are ready to look -at a full implementation, you've got one here... - -The best full description of JPEG is the textbook "JPEG Still Image Data -Compression Standard" by William B. Pennebaker and Joan L. Mitchell, published -by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1. Price US$59.95, 638 pp. -The book includes the complete text of the ISO JPEG standards (DIS 10918-1 -and draft DIS 10918-2). This is by far the most complete exposition of JPEG -in existence, and we highly recommend it. - -The JPEG standard itself is not available electronically; you must order a -paper copy through ISO or ITU. (Unless you feel a need to own a certified -official copy, we recommend buying the Pennebaker and Mitchell book instead; -it's much cheaper and includes a great deal of useful explanatory material.) -In the USA, copies of the standard may be ordered from ANSI Sales at (212) -642-4900, or from Global Engineering Documents at (800) 854-7179. (ANSI -doesn't take credit card orders, but Global does.) It's not cheap: as of -1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus 7% -shipping/handling. The standard is divided into two parts, Part 1 being the -actual specification, while Part 2 covers compliance testing methods. Part 1 -is titled "Digital Compression and Coding of Continuous-tone Still Images, -Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS -10918-1, ITU-T T.81. Part 2 is titled "Digital Compression and Coding of -Continuous-tone Still Images, Part 2: Compliance testing" and has document -numbers ISO/IEC IS 10918-2, ITU-T T.83. - -Some extensions to the original JPEG standard are defined in JPEG Part 3, -a newer ISO standard numbered ISO/IEC IS 10918-3 and ITU-T T.84. IJG -currently does not support any Part 3 extensions. - -The JPEG standard does not specify all details of an interchangeable file -format. For the omitted details we follow the "JFIF" conventions, revision -1.02. A copy of the JFIF spec is available from: - Literature Department - C-Cube Microsystems, Inc. - 1778 McCarthy Blvd. - Milpitas, CA 95035 - phone (408) 944-6300, fax (408) 944-6314 -A PostScript version of this document is available by FTP at -ftp://ftp.uu.net/graphics/jpeg/jfif.ps.gz. There is also a plain text -version at ftp://ftp.uu.net/graphics/jpeg/jfif.txt.gz, but it is missing -the figures. - -The TIFF 6.0 file format specification can be obtained by FTP from -ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz. The JPEG incorporation scheme -found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems. -IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6). -Instead, we recommend the JPEG design proposed by TIFF Technical Note #2 -(Compression tag 7). Copies of this Note can be obtained from ftp.sgi.com or -from ftp://ftp.uu.net/graphics/jpeg/. It is expected that the next revision -of the TIFF spec will replace the 6.0 JPEG design with the Note's design. -Although IJG's own code does not support TIFF/JPEG, the free libtiff library -uses our library to implement TIFF/JPEG per the Note. libtiff is available -from ftp://ftp.sgi.com/graphics/tiff/. - - -ARCHIVE LOCATIONS -================= - -The "official" archive site for this software is ftp.uu.net (Internet -address 192.48.96.9).

(Quite a -few of them use this library to do so.) The JPEG FAQ described above lists -some of the more popular free and shareware viewers, and tells where to -obtain them on Internet. - -If you are on a Unix machine, we highly recommend Jef Poskanzer's free -PBMPLUS software, which provides many useful operations on PPM-format image -files. In particular, it can convert PPM images to and from a wide range of -other formats, thus making cjpeg/djpeg considerably more useful. The latest -version is distributed by the NetPBM group, and is available from numerous -sites, notably ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/. -Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software is; -you are likely to have difficulty making it work on any non-Unix machine. - -A different free JPEG implementation, written by the PVRG group at Stanford, -is available from ftp://havefun.stanford.edu/pub/jpeg/. This program -is designed for research and experimentation rather than production use; -it is slower, harder to use, and less portable than the IJG code, but it -is easier to read and modify. Also, the PVRG code supports lossless JPEG, -which we do not. (On the other hand, it doesn't do progressive JPEG.) - - -FILE FORMAT WARS -================ - -Some JPEG programs produce files that are not compatible with our library. -The root of the problem is that the ISO JPEG committee failed to specify a -concrete file format. Some vendors "filled in the blanks" on their own, -creating proprietary formats that no one else could read. (For example, none -of the early commercial JPEG implementations for the Macintosh were able to -exchange compressed files.) - -The file format we have adopted is called JFIF (see REFERENCES). This format -has been agreed to by a number of major commercial JPEG vendors, and it has -become the de facto standard. JFIF is a minimal or "low end" representation. -We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF -Technical Note #2) for "high end" applications that need to record a lot of -additional data about an image. TIFF/JPEG is fairly new and not yet widely -supported, unfortunately. - -The upcoming JPEG Part 3 standard defines a file format called SPIFF. -SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should -be able to read the most common variant of SPIFF. SPIFF has some technical -advantages over JFIF, but its major claim to fame is simply that it is an -official standard rather than an informal one. At this point it is unclear -whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto -standard. IJG intends to support SPIFF once the standard is frozen, but we -have not decided whether it should become our default output format or not. -(In any case, our decoder will remain capable of reading JFIF indefinitely.) - -Various proprietary file formats incorporating JPEG compression also exist. -We have little or no sympathy for the existence of these formats. Indeed, -one of the original reasons for developing this free software was to help -force convergence on common, open format standards for JPEG files. Don't -use a proprietary file format! - - -TO DO -===== - -The major thrust for v7 will probably be improvement of visual quality. -The current method for scaling the quantization tables is known not to be -very good at low Q values. We also intend to investigate block boundary -smoothing, "poor man's variable quantization", and other means of improving -quality-vs-file-size performance without sacrificing compatibility. - -In future versions, we are considering supporting some of the upcoming JPEG -Part 3 extensions --- principally, variable quantization and the SPIFF file -format. - -As always, speeding things up is of great interest. - -Please send bug reports, offers of help, etc. to jpeg-info@uunet.uu.net. diff --git a/Build/source/extra/jpeg/ansi2knr.1 b/Build/source/extra/jpeg/ansi2knr.1 deleted file mode 100644 index f9ee5a631c2..00000000000 --- a/Build/source/extra/jpeg/ansi2knr.1 +++ /dev/null @@ -1,36 +0,0 @@ -.TH ANSI2KNR 1 "19 Jan 1996" -.SH NAME -ansi2knr \- convert ANSI C to Kernighan & Ritchie C -.SH SYNOPSIS -.I ansi2knr -[--varargs] input_file [output_file] -.SH DESCRIPTION -If no output_file is supplied, output goes to stdout. -.br -There are no error messages. -.sp -.I ansi2knr -recognizes function definitions by seeing a non-keyword identifier at the left -margin, followed by a left parenthesis, with a right parenthesis as the last -character on the line, and with a left brace as the first token on the -following line (ignoring possible intervening comments).

You can also use this wording - to make the terms for other programs. - - The license agreements of most software companies keep you at the -mercy of those companies. By contrast, our general public license is -intended to give everyone the right to share Ghostscript. To make sure -that you get the rights we want you to have, we need to make -restrictions that forbid anyone to deny you these rights or to ask you -to surrender the rights. Hence this license agreement. - - Specifically, we want to make sure that you have the right to give -away copies of Ghostscript, that you receive source code or else can get -it if you want it, that you can change Ghostscript or use pieces of it -in new free programs, and that you know you can do these things. - - To make sure that everyone has such rights, we have to forbid you to -deprive anyone else of these rights. For example, if you distribute -copies of Ghostscript, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must tell them their rights. - - Also, for our own protection, we must make certain that everyone finds -out that there is no warranty for Ghostscript.

You may copy and distribute Ghostscript (or a portion or derivative -of it, under Paragraph 2) in object code or executable form under the -terms of Paragraphs 1 and 2 above provided that you also do one of the -following: - - a) accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of - Paragraphs 1 and 2 above; or, - - b) accompany it with a written offer, valid for at least three - years, to give any third party free (except for a nominal - shipping charge) a complete machine-readable copy of the - corresponding source code, to be distributed under the terms of - Paragraphs 1 and 2 above; or, - - c) accompany it with the information you received as to where the - corresponding source code may be obtained. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form alone.) - -For an executable file, complete source code means all the source code for -all modules it contains; but, as a special exception, it need not include -source code for modules which are standard libraries that accompany the -operating system on which the executable file runs. - - 4. You may not copy, sublicense, distribute or transfer Ghostscript -except as expressly provided under this License Agreement.

Targa files that contain an "identification" -field will not be automatically recognized by -.BR cjpeg ; -for such files you must specify -.B \-targa -to make -.B cjpeg -treat the input as Targa format. -For most Targa files, you won't need this switch. -.PP -The -.B \-quality -switch lets you trade off compressed file size against quality of the -reconstructed image: the higher the quality setting, the larger the JPEG file, -and the closer the output image will be to the original input. Normally you -want to use the lowest quality setting (smallest file) that decompresses into -something visually indistinguishable from the original image. For this -purpose the quality setting should be between 50 and 95; the default of 75 is -often about right. If you see defects at -.B \-quality -75, then go up 5 or 10 counts at a time until you are happy with the output -image. (The optimal setting will vary from one image to another.) -.PP -.B \-quality -100 will generate a quantization table of all 1's, minimizing loss in the -quantization step (but there is still information loss in subsampling, as well -as roundoff error). This setting is mainly of interest for experimental -purposes. Quality values above about 95 are -.B not -recommended for normal use; the compressed file size goes up dramatically for -hardly any gain in output image quality. -.PP -In the other direction, quality values below 50 will produce very small files -of low image quality. Settings around 5 to 10 might be useful in preparing an -index of a large image library, for example. Try -.B \-quality -2 (or so) for some amusing Cubist effects. (Note: quality -values below about 25 generate 2-byte quantization tables, which are -considered optional in the JPEG standard. -.B cjpeg -emits a warning message when you give such a quality value, because some -other JPEG programs may be unable to decode the resulting file. Use -.B \-baseline -if you need to ensure compatibility at low quality values.) -.PP -The -.B \-progressive -switch creates a "progressive JPEG" file. In this type of JPEG file, the data -is stored in multiple scans of increasing quality. If the file is being -transmitted over a slow communications link, the decoder can use the first -scan to display a low-quality image very quickly, and can then improve the -display with each subsequent scan. The final image is exactly equivalent to a -standard JPEG file of the same quality setting, and the total file size is -about the same --- often a little smaller. -.B Caution: -progressive JPEG is not yet widely implemented, so many decoders will be -unable to view a progressive JPEG file at all. -.PP -Switches for advanced users: -.TP -.B \-dct int -Use integer DCT method (default). -.TP -.B \-dct fast -Use fast integer DCT (less accurate). -.TP -.B \-dct float -Use floating-point DCT method. -The float method is very slightly more accurate than the int method, but is -much slower unless your machine has very fast floating-point hardware. Also -note that results of the floating-point method may vary slightly across -machines, while the integer methods should give the same results everywhere. -The fast integer method is much less accurate than the other two. -.TP -.BI \-restart " N" -Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is -attached to the number. -.B \-restart 0 -(the default) means no restart markers. -.TP -.BI \-smooth " N" -Smooth the input image to eliminate dithering noise. N, ranging from 1 to -100, indicates the strength of smoothing. 0 (the default) means no smoothing. -.TP -.BI \-maxmemory " N" -Set limit for amount of memory to use in processing large images. Value is -in thousands of bytes, or millions of bytes if "M" is attached to the -number. For example, -.B \-max 4m -selects 4000000 bytes. If more space is needed, temporary files will be used. -.TP -.BI \-outfile " name" -Send output image to the named file, not to standard output. -.TP -.B \-verbose -Enable debug printout. More -.BR \-v 's -give more output. Also, version information is printed at startup. -.TP -.B \-debug -Same as -.BR \-verbose . -.PP -The -.B \-restart -option inserts extra markers that allow a JPEG decoder to resynchronize after -a transmission error. Without restart markers, any damage to a compressed -file will usually ruin the image from the point of the error to the end of the -image; with restart markers, the damage is usually confined to the portion of -the image up to the next restart marker. Of course, the restart markers -occupy extra space. We recommend -.B \-restart 1 -for images that will be transmitted across unreliable networks such as Usenet. -.PP -The -.B \-smooth -option filters the input to eliminate fine-scale noise. This is often useful -when converting dithered images to JPEG: a moderate smoothing factor of 10 to -50 gets rid of dithering patterns in the input file, resulting in a smaller -JPEG file and a better-looking image. Too large a smoothing factor will -visibly blur the image, however. -.PP -Switches for wizards: -.TP -.B \-baseline -Force baseline-compatible quantization tables to be generated. This clamps -quantization values to 8 bits even at low quality settings. (This switch is -poorly named, since it does not ensure that the output is actually baseline -JPEG. For example, you can use -.B \-baseline -and -.B \-progressive -together.) -.TP -.BI \-qtables " file" -Use the quantization tables given in the specified text file. -.TP -.BI \-qslots " N[,...]" -Select which quantization table to use for each color component. -.TP -.BI \-sample " HxV[,...]" -Set JPEG sampling factors for each color component. -.TP -.BI \-scans " file" -Use the scan script given in the specified text file. -.PP -The "wizard" switches are intended for experimentation with JPEG. If you -don't know what you are doing, \fBdon't use them\fR. These switches are -documented further in the file wizard.doc. -.SH EXAMPLES -.LP -This example compresses the PPM file foo.ppm with a quality factor of -60 and saves the output as foo.jpg: -.IP -.B cjpeg \-quality -.I 60 foo.ppm -.B > -.I foo.jpg -.SH HINTS -Color GIF files are not the ideal input for JPEG; JPEG is really intended for -compressing full-color (24-bit) images. In particular, don't try to convert -cartoons, line drawings, and other images that have only a few distinct -colors. GIF works great on these, JPEG does not. If you want to convert a -GIF to JPEG, you should experiment with -.BR cjpeg 's -.B \-quality -and -.B \-smooth -options to get a satisfactory conversion. -.B \-smooth 10 -or so is often helpful. -.PP -Avoid running an image through a series of JPEG compression/decompression -cycles. Image quality loss will accumulate; after ten or so cycles the image -may be noticeably worse than it was after one cycle. It's best to use a -lossless format while manipulating an image, then convert to JPEG format when -you are ready to file the image away. -.PP -The -.B \-optimize -option to -.B cjpeg -is worth using when you are making a "final" version for posting or archiving. -It's also a win when you are using low quality settings to make very small -JPEG files; the percentage improvement is often a lot more than it is on -larger files. (At present, -.B \-optimize -mode is always selected when generating progressive JPEG files.) -.SH ENVIRONMENT -.TP -.B JPEGMEM -If this environment variable is set, its value is the default memory limit. -The value is specified as described for the -.B \-maxmemory -switch. -.B JPEGMEM -overrides the default value specified when the program was compiled, and -itself is overridden by an explicit -.BR \-maxmemory . -.SH SEE ALSO -.BR djpeg (1), -.BR jpegtran (1), -.BR rdjpgcom (1), -.BR wrjpgcom (1) -.br -.BR ppm (5), -.BR pgm (5) -.br -Wallace, Gregory K.

The goal of using similar coding styles -is much more important than the details of just what that style is. - -In general we follow the recommendations of "Recommended C Style and Coding -Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and -Brader). This document is available in the IJG FTP archive (see -jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl). - -Block comments should be laid out thusly: - -/* - * Block comments in this style. - */ - -We indent statements in K&R style, e.g., - if (test) { - then-part; - } else { - else-part; - } -with two spaces per indentation level. (This indentation convention is -handled automatically by GNU Emacs and many other text editors.) - -Multi-word names should be written in lower case with underscores, e.g., -multi_word_name (not multiWordName). Preprocessor symbols and enum constants -are similar but upper case (MULTI_WORD_NAME). Names should be unique within -the first fifteen characters. (On some older systems, global names must be -unique within six characters. We accommodate this without cluttering the -source code by using macros to substitute shorter names.) - -We use function prototypes everywhere; we rely on automatic source code -transformation to feed prototype-less C compilers. Transformation is done -by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript). -ansi2knr is not very bright, so it imposes a format requirement on function -declarations: the function name MUST BEGIN IN COLUMN 1. Thus all functions -should be written in the following style: - -LOCAL(int *) -function_name (int a, char *b) -{ - code... -} - -Note that each function definition must begin with GLOBAL(type), LOCAL(type), -or METHODDEF(type). These macros expand to "static type" or just "type" as -appropriate. They provide a readable indication of the routine's usage and -can readily be changed for special needs. (For instance, special linkage -keywords can be inserted for use in Windows DLLs.) - -ansi2knr does not transform method declarations (function pointers in -structs). We handle these with a macro JMETHOD, defined as - #ifdef HAVE_PROTOTYPES - #define JMETHOD(type,methodname,arglist) type (*methodname) arglist - #else - #define JMETHOD(type,methodname,arglist) type (*methodname) () - #endif -which is used like this: - struct function_pointers { - JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp)); - JMETHOD(void, term_entropy_encoder, (void)); - }; -Note the set of parentheses surrounding the parameter list. - -A similar solution is used for forward and external function declarations -(see the EXTERN and JPP macros). - -If the code is to work on non-ANSI compilers, we cannot rely on a prototype -declaration to coerce actual parameters into the right types. Therefore, use -explicit casts on actual parameters whenever the actual parameter type is not -identical to the formal parameter. Beware of implicit conversions to "int". - -It seems there are some non-ANSI compilers in which the sizeof() operator -is defined to return int, yet size_t is defined as long. Needless to say, -this is brain-damaged. Always use the SIZEOF() macro in place of sizeof(), -so that the result is guaranteed to be of type size_t. - - -The JPEG library is intended to be used within larger programs. Furthermore, -we want it to be reentrant so that it can be used by applications that process -multiple images concurrently. The following rules support these requirements: - -1. Avoid direct use of file I/O, "malloc", error report printouts, etc; -pass these through the common routines provided. - -2. Minimize global namespace pollution. Functions should be declared static -wherever possible. (Note that our method-based calling conventions help this -a lot: in many modules only the initialization function will ever need to be -called directly, so only that function need be externally visible.) All -global function names should begin with "jpeg_", and should have an -abbreviated name (unique in the first six characters) substituted by macro -when NEED_SHORT_EXTERNAL_NAMES is set. - -3. Don't use global variables; anything that must be used in another module -should be in the common data structures. - -4. Don't use static variables except for read-only constant tables. Variables -that should be private to a module can be placed into private structures (see -the system architecture document, structure.doc). - -5. Source file names should begin with "j" for files that are part of the -library proper; source files that are not part of the library, such as cjpeg.c -and djpeg.c, do not begin with "j". Keep source file names to eight -characters (plus ".c" or ".h", etc) to make life easy for MS-DOSers. Keep -compression and decompression code in separate source files --- some -applications may want only one half of the library. - -Note: these rules (particularly #4) are not followed religiously in the -modules that are used in cjpeg/djpeg but are not part of the JPEG library -proper. Those modules are not really intended to be used in other -applications. diff --git a/Build/source/extra/jpeg/config.guess b/Build/source/extra/jpeg/config.guess deleted file mode 100644 index e792aac6080..00000000000 --- a/Build/source/extra/jpeg/config.guess +++ /dev/null @@ -1,1494 +0,0 @@ -#! /bin/sh -# Attempt to guess a canonical system name. -# Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, -# 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 -# Free Software Foundation, Inc. - -timestamp='2009-09-18' - -# This file is free software; you can redistribute it and/or modify it -# under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2 of the License, or -# (at your option) any later version. -# -# This program is distributed in the hope that it will be useful, but -# WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

PBMPLUS (PPM/PGM), BMP, -GIF, Targa, or RLE (Utah Raster Toolkit) output format can be selected. -(RLE is supported only if the URT library is available.) -.SH OPTIONS -All switch names may be abbreviated; for example, -.B \-grayscale -may be written -.B \-gray -or -.BR \-gr . -Most of the "basic" switches can be abbreviated to as little as one letter. -Upper and lower case are equivalent (thus -.B \-BMP -is the same as -.BR \-bmp ). -British spellings are also accepted (e.g., -.BR \-greyscale ), -though for brevity these are not mentioned below. -.PP -The basic switches are: -.TP -.BI \-colors " N" -Reduce image to at most N colors. This reduces the number of colors used in -the output image, so that it can be displayed on a colormapped display or -stored in a colormapped file format. For example, if you have an 8-bit -display, you'd need to reduce to 256 or fewer colors. -.TP -.BI \-quantize " N" -Same as -.BR \-colors . -.B \-colors -is the recommended name, -.B \-quantize -is provided only for backwards compatibility. -.TP -.B \-fast -Select recommended processing options for fast, low quality output. (The -default options are chosen for highest quality output.) Currently, this is -equivalent to \fB\-dct fast \-nosmooth \-onepass \-dither ordered\fR. -.TP -.B \-grayscale -Force gray-scale output even if JPEG file is color. Useful for viewing on -monochrome displays; also, -.B djpeg -runs noticeably faster in this mode. -.TP -.BI \-scale " M/N" -Scale the output image by a factor M/N. Currently the scale factor must be -1/1, 1/2, 1/4, or 1/8. Scaling is handy if the image is larger than your -screen; also, -.B djpeg -runs much faster when scaling down the output. -.TP -.B \-bmp -Select BMP output format (Windows flavor). 8-bit colormapped format is -emitted if -.B \-colors -or -.B \-grayscale -is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color -format is emitted. -.TP -.B \-gif -Select GIF output format. Since GIF does not support more than 256 colors, -.B \-colors 256 -is assumed (unless you specify a smaller number of colors). -.TP -.B \-os2 -Select BMP output format (OS/2 1.x flavor). 8-bit colormapped format is -emitted if -.B \-colors -or -.B \-grayscale -is specified, or if the JPEG file is gray-scale; otherwise, 24-bit full-color -format is emitted. -.TP -.B \-pnm -Select PBMPLUS (PPM/PGM) output format (this is the default format). -PGM is emitted if the JPEG file is gray-scale or if -.B \-grayscale -is specified; otherwise PPM is emitted. -.TP -.B \-rle -Select RLE output format. (Requires URT library.) -.TP -.B \-targa -Select Targa output format. Gray-scale format is emitted if the JPEG file is -gray-scale or if -.B \-grayscale -is specified; otherwise, colormapped format is emitted if -.B \-colors -is specified; otherwise, 24-bit full-color format is emitted. -.PP -Switches for advanced users: -.TP -.B \-dct int -Use integer DCT method (default). -.TP -.B \-dct fast -Use fast integer DCT (less accurate). -.TP -.B \-dct float -Use floating-point DCT method. -The float method is very slightly more accurate than the int method, but is -much slower unless your machine has very fast floating-point hardware. Also -note that results of the floating-point method may vary slightly across -machines, while the integer methods should give the same results everywhere. -The fast integer method is much less accurate than the other two. -.TP -.B \-dither fs -Use Floyd-Steinberg dithering in color quantization. -.TP -.B \-dither ordered -Use ordered dithering in color quantization. -.TP -.B \-dither none -Do not use dithering in color quantization. -By default, Floyd-Steinberg dithering is applied when quantizing colors; this -is slow but usually produces the best results. Ordered dither is a compromise -between speed and quality; no dithering is fast but usually looks awful. Note -that these switches have no effect unless color quantization is being done. -Ordered dither is only available in -.B \-onepass -mode. -.TP -.BI \-map " file" -Quantize to the colors used in the specified image file. This is useful for -producing multiple files with identical color maps, or for forcing a -predefined set of colors to be used. The -.I file -must be a GIF or PPM file. This option overrides -.B \-colors -and -.BR \-onepass . -.TP -.B \-nosmooth -Use a faster, lower-quality upsampling routine. -.TP -.B \-onepass -Use one-pass instead of two-pass color quantization. The one-pass method is -faster and needs less memory, but it produces a lower-quality image. -.B \-onepass -is ignored unless you also say -.B \-colors -.IR N . -Also, the one-pass method is always used for gray-scale output (the two-pass -method is no improvement then). -.TP -.BI \-maxmemory " N" -Set limit for amount of memory to use in processing large images. Value is -in thousands of bytes, or millions of bytes if "M" is attached to the -number. For example, -.B \-max 4m -selects 4000000 bytes. If more space is needed, temporary files will be used. -.TP -.BI \-outfile " name" -Send output image to the named file, not to standard output. -.TP -.B \-verbose -Enable debug printout. More -.BR \-v 's -give more output. Also, version information is printed at startup. -.TP -.B \-debug -Same as -.BR \-verbose . -.SH EXAMPLES -.LP -This example decompresses the JPEG file foo.jpg, quantizes it to -256 colors, and saves the output in 8-bit BMP format in foo.bmp: -.IP -.B djpeg \-colors 256 \-bmp -.I foo.jpg -.B > -.I foo.bmp -.SH HINTS -To get a quick preview of an image, use the -.B \-grayscale -and/or -.B \-scale -switches. -.B \-grayscale \-scale 1/8 -is the fastest case. -.PP -Several options are available that trade off image quality to gain speed. -.B \-fast -turns on the recommended settings. -.PP -.B \-dct fast -and/or -.B \-nosmooth -gain speed at a small sacrifice in quality. -When producing a color-quantized image, -.B \-onepass \-dither ordered -is fast but much lower quality than the default behavior. -.B \-dither none -may give acceptable results in two-pass mode, but is seldom tolerable in -one-pass mode. -.PP -If you are fortunate enough to have very fast floating point hardware, -\fB\-dct float\fR may be even faster than \fB\-dct fast\fR. But on most -machines \fB\-dct float\fR is slower than \fB\-dct int\fR; in this case it is -not worth using, because its theoretical accuracy advantage is too small to be -significant in practice. -.SH ENVIRONMENT -.TP -.B JPEGMEM -If this environment variable is set, its value is the default memory limit. -The value is specified as described for the -.B \-maxmemory -switch. -.B JPEGMEM -overrides the default value specified when the program was compiled, and -itself is overridden by an explicit -.BR \-maxmemory . -.SH SEE ALSO -.BR cjpeg (1), -.BR jpegtran (1), -.BR rdjpgcom (1), -.BR wrjpgcom (1) -.br -.BR ppm (5), -.BR pgm (5) -.br -Wallace, Gregory K.

We have -tried to make this software extremely portable and flexible, so that it can be -adapted to almost any environment. The downside of this decision is that the -installation process is complicated. We have provided shortcuts to simplify -the task on common systems. But in any case, you will need at least a little -familiarity with C programming and program build procedures for your system. - -If you are only using this software as part of a larger program, the larger -program's installation procedure may take care of configuring the IJG code. -For example, Ghostscript's installation script will configure the IJG code. -You don't need to read this file if you just want to compile Ghostscript. - -If you are on a Unix machine, you may not need to read this file at all. -Try doing - ./configure - make - make test -If that doesn't complain, do - make install -(better do "make -n install" first to see if the makefile will put the files -where you want them).

However, there is a potential for error if you needed to convert the -files to the local standard text file format (for example, if you are on -MS-DOS you may have converted LF end-of-line to CR/LF). You must apply -such conversion to all the files EXCEPT those whose names begin with "test". -The test files contain binary data; if you change them in any way then the -self-test will give bad results. - -Please check the last section of this file to see if there are hints for the -specific machine or compiler you are using. - - -CONFIGURING THE SOFTWARE -======================== - -To configure the IJG code for your system, you need to create two files: - * jconfig.h: contains values for system-dependent #define symbols. - * Makefile: controls the compilation process. -(On a non-Unix machine, you may create "project files" or some other -substitute for a Makefile. jconfig.h is needed in any environment.) - -We provide three different ways to generate these files: - * On a Unix system, you can just run the "configure" script. - * We provide sample jconfig files and makefiles for popular machines; - if your machine matches one of the samples, just copy the right sample - files to jconfig.h and Makefile. - * If all else fails, read the instructions below and make your own files. - - -Configuring the software using the automatic "configure" script ---------------------------------------------------------------- - -If you are on a Unix machine, you can just type - ./configure -and let the configure script construct appropriate configuration files. -If you're using "csh" on an old version of System V, you might need to type - sh configure -instead to prevent csh from trying to execute configure itself. -Expect configure to run for a few minutes, particularly on slower machines; -it works by compiling a series of test programs. - -Configure was created with GNU Autoconf and it follows the usual conventions -for GNU configure scripts. It makes a few assumptions that you may want to -override. You can do this by providing optional switches to configure: - -* If you want to build libjpeg as a shared library, say - ./configure --enable-shared -To get both shared and static libraries, say - ./configure --enable-shared --enable-static -Note that these switches invoke GNU libtool to take care of system-dependent -shared library building methods. If things don't work this way, please try -running configure without either switch; that should build a static library -without using libtool. If that works, your problem is probably with libtool -not with the IJG code. libtool is fairly new and doesn't support all flavors -of Unix yet. (You might be able to find a newer version of libtool than the -one included with libjpeg; see ftp.gnu.org. Report libtool problems to -bug-libtool@gnu.org.) - -* Configure will use gcc (GNU C compiler) if it's available, otherwise cc. -To force a particular compiler to be selected, use the CC option, for example - ./configure CC='cc' -The same method can be used to include any unusual compiler switches. -For example, on HP-UX you probably want to say - ./configure CC='cc -Aa' -to get HP's compiler to run in ANSI mode. - -* The default CFLAGS setting is "-O" for non-gcc compilers, "-O2" for gcc. -You can override this by saying, for example, - ./configure CFLAGS='-g' -if you want to compile with debugging support. - -* Configure will set up the makefile so that "make install" will install files -into /usr/local/bin, /usr/local/man, etc. You can specify an installation -prefix other than "/usr/local" by giving configure the option "--prefix=PATH". - -* If you don't have a lot of swap space, you may need to enable the IJG -software's internal virtual memory mechanism. To do this, give the option -"--enable-maxmem=N" where N is the default maxmemory limit in megabytes. -This is discussed in more detail under "Selecting a memory manager", below. -You probably don't need to worry about this on reasonably-sized Unix machines, -unless you plan to process very large images. - -Configure has some other features that are useful if you are cross-compiling -or working in a network of multiple machine types; but if you need those -features, you probably already know how to use them. - - -Configuring the software using one of the supplied jconfig and makefile files ------------------------------------------------------------------------------ - -If you have one of these systems, you can just use the provided configuration -files: - -Makefile jconfig file System and/or compiler - -makefile.manx jconfig.manx Amiga, Manx Aztec C -makefile.sas jconfig.sas Amiga, SAS C -makeproj.mac jconfig.mac Apple Macintosh, Metrowerks CodeWarrior -mak*jpeg.st jconfig.st Atari ST/STE/TT, Pure C or Turbo C -makefile.bcc jconfig.bcc MS-DOS or OS/2, Borland C -makefile.dj jconfig.dj MS-DOS, DJGPP (Delorie's port of GNU C) -makefile.mc6 jconfig.mc6 MS-DOS, Microsoft C (16-bit only) -makefile.wat jconfig.wat MS-DOS, OS/2, or Windows NT, Watcom C -makefile.vc jconfig.vc Windows NT/95, MS Visual C++ -make*.ds jconfig.vc Windows NT/95, MS Developer Studio -makefile.mms jconfig.vms Digital VMS, with MMS software -makefile.vms jconfig.vms Digital VMS, without MMS software - -Copy the proper jconfig file to jconfig.h and the makefile to Makefile (or -whatever your system uses as the standard makefile name). For more info see -the appropriate system-specific hints section near the end of this file. - - -Configuring the software by hand --------------------------------- - -First, generate a jconfig.h file. If you are moderately familiar with C, -the comments in jconfig.doc should be enough information to do this; just -copy jconfig.doc to jconfig.h and edit it appropriately. Otherwise, you may -prefer to use the ckconfig.c program. You will need to compile and execute -ckconfig.c by hand --- we hope you know at least enough to do that. -ckconfig.c may not compile the first try (in fact, the whole idea is for it -to fail if anything is going to). If you get compile errors, fix them by -editing ckconfig.c according to the directions given in ckconfig.c. Once -you get it to run, it will write a suitable jconfig.h file, and will also -print out some advice about which makefile to use. - -You may also want to look at the canned jconfig files, if there is one for a -system similar to yours. - -Second, select a makefile and copy it to Makefile (or whatever your system -uses as the standard makefile name). The most generic makefiles we provide -are - makefile.ansi: if your C compiler supports function prototypes - makefile.unix: if not. -(You have function prototypes if ckconfig.c put "#define HAVE_PROTOTYPES" -in jconfig.h.) You may want to start from one of the other makefiles if -there is one for a system similar to yours. - -Look over the selected Makefile and adjust options as needed. In particular -you may want to change the CC and CFLAGS definitions. For instance, if you -are using GCC, set CC=gcc. If you had to use any compiler switches to get -ckconfig.c to work, make sure the same switches are in CFLAGS. - -If you are on a system that doesn't use makefiles, you'll need to set up -project files (or whatever you do use) to compile all the source files and -link them into executable files cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom. -See the file lists in any of the makefiles to find out which files go into -each program. Note that the provided makefiles all make a "library" file -libjpeg first, but you don't have to do that if you don't want to; the file -lists identify which source files are actually needed for compression, -decompression, or both. As a last resort, you can make a batch script that -just compiles everything and links it all together; makefile.vms is an example -of this (it's for VMS systems that have no make-like utility). - -Here are comments about some specific configuration decisions you'll -need to make: - -Command line style ------------------- - -These programs can use a Unix-like command line style which supports -redirection and piping, like this: - cjpeg inputfile >outputfile - cjpeg outputfile - source program | cjpeg >outputfile -The simpler "two file" command line style is just - cjpeg inputfile outputfile -You may prefer the two-file style, particularly if you don't have pipes. - -You MUST use two-file style on any system that doesn't cope well with binary -data fed through stdin/stdout; this is true for some MS-DOS compilers, for -example. If you're not on a Unix system, it's safest to assume you need -two-file style. (But if your compiler provides either the Posix-standard -fdopen() library routine or a Microsoft-compatible setmode() routine, you -can safely use the Unix command line style, by defining USE_FDOPEN or -USE_SETMODE respectively.) - -To use the two-file style, make jconfig.h say "#define TWO_FILE_COMMANDLINE". - -Selecting a memory manager --------------------------- - -The IJG code is capable of working on images that are too big to fit in main -memory; data is swapped out to temporary files as necessary. However, the -code to do this is rather system-dependent. We provide five different -memory managers: - -* jmemansi.c This version uses the ANSI-standard library routine tmpfile(), - which not all non-ANSI systems have. On some systems - tmpfile() may put the temporary file in a non-optimal - location; if you don't like what it does, use jmemname.c. - -* jmemname.c This version creates named temporary files. For anything - except a Unix machine, you'll need to configure the - select_file_name() routine appropriately; see the comments - near the head of jmemname.c. If you use this version, define - NEED_SIGNAL_CATCHER in jconfig.h to make sure the temp files - are removed if the program is aborted. - -* jmemnobs.c (That stands for No Backing Store :-).) This will compile on - almost any system, but it assumes you have enough main memory - or virtual memory to hold the biggest images you work with. - -* jmemdos.c This should be used with most 16-bit MS-DOS compilers. - See the system-specific notes about MS-DOS for more info. - IMPORTANT: if you use this, define USE_MSDOS_MEMMGR in - jconfig.h, and include the assembly file jmemdosa.asm in the - programs. The supplied makefiles and jconfig files for - 16-bit MS-DOS compilers already do both. - -* jmemmac.c Custom version for Apple Macintosh; see the system-specific - notes for Macintosh for more info. - -To use a particular memory manager, change the SYSDEPMEM variable in your -makefile to equal the corresponding object file name (for example, jmemansi.o -or jmemansi.obj for jmemansi.c). - -If you have plenty of (real or virtual) main memory, just use jmemnobs.c. -"Plenty" means about ten bytes for every pixel in the largest images -you plan to process, so a lot of systems don't meet this criterion. -If yours doesn't, try jmemansi.c first. If that doesn't compile, you'll have -to use jmemname.c; be sure to adjust select_file_name() for local conditions. -You may also need to change unlink() to remove() in close_backing_store(). - -Except with jmemnobs.c or jmemmac.c, you need to adjust the DEFAULT_MAX_MEM -setting to a reasonable value for your system (either by adding a #define for -DEFAULT_MAX_MEM to jconfig.h, or by adding a -D switch to the Makefile). -This value limits the amount of data space the program will attempt to -allocate. Code and static data space isn't counted, so the actual memory -needs for cjpeg or djpeg are typically 100 to 150Kb more than the max-memory -setting. Larger max-memory settings reduce the amount of I/O needed to -process a large image, but too large a value can result in "insufficient -memory" failures. On most Unix machines (and other systems with virtual -memory), just set DEFAULT_MAX_MEM to several million and forget it. At the -other end of the spectrum, for MS-DOS machines you probably can't go much -above 300K to 400K. (On MS-DOS the value refers to conventional memory only. -Extended/expanded memory is handled separately by jmemdos.c.) - - -BUILDING THE SOFTWARE -===================== - -Now you should be able to compile the software. Just say "make" (or -whatever's necessary to start the compilation). Have a cup of coffee. - -Here are some things that could go wrong: - -If your compiler complains about undefined structures, you should be able to -shut it up by putting "#define INCOMPLETE_TYPES_BROKEN" in jconfig.h. - -If you have trouble with missing system include files or inclusion of the -wrong ones, read jinclude.h. This shouldn't happen if you used configure -or ckconfig.c to set up jconfig.h. - -There are a fair number of routines that do not use all of their parameters; -some compilers will issue warnings about this, which you can ignore. There -are also a few configuration checks that may give "unreachable code" warnings. -Any other warning deserves investigation. - -If you don't have a getenv() library routine, define NO_GETENV. - -Also see the system-specific hints, below. - - -TESTING THE SOFTWARE -==================== - -As a quick test of functionality we've included a small sample image in -several forms: - testorig.jpg Starting point for the djpeg tests. - testimg.ppm The output of djpeg testorig.jpg - testimg.bmp The output of djpeg -bmp -colors 256 testorig.jpg - testimg.jpg The output of cjpeg testimg.ppm - testprog.jpg Progressive-mode equivalent of testorig.jpg. - testimgp.jpg The output of cjpeg -progressive -optimize testimg.ppm -(The first- and second-generation .jpg files aren't identical since JPEG is -lossy.) If you can generate duplicates of the testimg* files then you -probably have working programs. - -With most of the makefiles, "make test" will perform the necessary -comparisons. - -If you're using a makefile that doesn't provide the test option, run djpeg -and cjpeg by hand and compare the output files to testimg* with whatever -binary file comparison tool you have. The files should be bit-for-bit -identical. - -If the programs complain "MAX_ALLOC_CHUNK is wrong, please fix", then you -need to reduce MAX_ALLOC_CHUNK to a value that fits in type size_t. -Try adding "#define MAX_ALLOC_CHUNK 65520L" to jconfig.h. A less likely -configuration error is "ALIGN_TYPE is wrong, please fix": defining ALIGN_TYPE -as long should take care of that one. - -If the cjpeg test run fails with "Missing Huffman code table entry", it's a -good bet that you needed to define RIGHT_SHIFT_IS_UNSIGNED. Go back to the -configuration step and run ckconfig.c. (This is a good plan for any other -test failure, too.) - -If you are using Unix (one-file) command line style on a non-Unix system, -it's a good idea to check that binary I/O through stdin/stdout actually -works. You should get the same results from "djpeg out.ppm" -as from "djpeg -outfile out.ppm testorig.jpg". Note that the makefiles all -use the latter style and therefore do not exercise stdin/stdout! If this -check fails, try recompiling with USE_SETMODE or USE_FDOPEN defined. -If it still doesn't work, better use two-file style. - -If you chose a memory manager other than jmemnobs.c, you should test that -temporary-file usage works. Try "djpeg -bmp -colors 256 -max 0 testorig.jpg" -and make sure its output matches testimg.bmp. If you have any really large -images handy, try compressing them with -optimize and/or decompressing with --colors 256 to make sure your DEFAULT_MAX_MEM setting is not too large. - -NOTE: this is far from an exhaustive test of the JPEG software; some modules, -such as 1-pass color quantization, are not exercised at all. It's just a -quick test to give you some confidence that you haven't missed something -major. - - -INSTALLING THE SOFTWARE -======================= - -Once you're done with the above steps, you can install the software by -copying the executable files (cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom) -to wherever you normally install programs. On Unix systems, you'll also want -to put the man pages (cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1) -in the man-page directory. The pre-fab makefiles don't support this step -since there's such a wide variety of installation procedures on different -systems. - -If you generated a Makefile with the "configure" script, you can just say - make install -to install the programs and their man pages into the standard places. -(You'll probably need to be root to do this.) We recommend first saying - make -n install -to see where configure thought the files should go. You may need to edit -the Makefile, particularly if your system's conventions for man page -filenames don't match what configure expects. - -If you want to install the IJG library itself, for use in compiling other -programs besides ours, then you need to put the four include files - jpeglib.h jerror.h jconfig.h jmorecfg.h -into your include-file directory, and put the library file libjpeg.a -(extension may vary depending on system) wherever library files go. -If you generated a Makefile with "configure", it will do what it thinks -is the right thing if you say - make install-lib - - -OPTIONAL STUFF -============== - -Progress monitor: - -If you like, you can #define PROGRESS_REPORT (in jconfig.h) to enable display -of percent-done progress reports. The routine provided in cdjpeg.c merely -prints percentages to stderr, but you can customize it to do something -fancier. - -Utah RLE file format support: - -We distribute the software with support for RLE image files (Utah Raster -Toolkit format) disabled, because the RLE support won't compile without the -Utah library. If you have URT version 3.1 or later, you can enable RLE -support as follows: - 1. #define RLE_SUPPORTED in jconfig.h. - 2. Add a -I option to CFLAGS in the Makefile for the directory - containing the URT .h files (typically the "include" - subdirectory of the URT distribution). - 3. Add -L... -lrle to LDLIBS in the Makefile, where ... specifies - the directory containing the URT "librle.a" file (typically the - "lib" subdirectory of the URT distribution). - -Support for 12-bit-deep pixel data: - -The JPEG standard allows either 8-bit or 12-bit data precision. (For color, -this means 8 or 12 bits per channel, of course.) If you need to work with -deeper than 8-bit data, you can compile the IJG code for 12-bit operation. -To do so: - 1. In jmorecfg.h, define BITS_IN_JSAMPLE as 12 rather than 8. - 2. In jconfig.h, undefine BMP_SUPPORTED, RLE_SUPPORTED, and TARGA_SUPPORTED, - because the code for those formats doesn't handle 12-bit data and won't - even compile. (The PPM code does work, as explained below. The GIF - code works too; it scales 8-bit GIF data to and from 12-bit depth - automatically.) - 3. Compile. Don't expect "make test" to pass, since the supplied test - files are for 8-bit data. - -Currently, 12-bit support does not work on 16-bit-int machines. - -Note that a 12-bit version will not read 8-bit JPEG files, nor vice versa; -so you'll want to keep around a regular 8-bit compilation as well. -(Run-time selection of data depth, to allow a single copy that does both, -is possible but would probably slow things down considerably; it's very low -on our to-do list.) - -The PPM reader (rdppm.c) can read 12-bit data from either text-format or -binary-format PPM and PGM files. Binary-format PPM/PGM files which have a -maxval greater than 255 are assumed to use 2 bytes per sample, LSB first -(little-endian order). As of early 1995, 2-byte binary format is not -officially supported by the PBMPLUS library, but it is expected that a -future release of PBMPLUS will support it. Note that the PPM reader will -read files of any maxval regardless of the BITS_IN_JSAMPLE setting; incoming -data is automatically rescaled to either maxval=255 or maxval=4095 as -appropriate for the cjpeg bit depth. - -The PPM writer (wrppm.c) will normally write 2-byte binary PPM or PGM -format, maxval 4095, when compiled with BITS_IN_JSAMPLE=12. Since this -format is not yet widely supported, you can disable it by compiling wrppm.c -with PPM_NORAWWORD defined; then the data is scaled down to 8 bits to make a -standard 1-byte/sample PPM or PGM file. (Yes, this means still another copy -of djpeg to keep around. But hopefully you won't need it for very long. -Poskanzer's supposed to get that new PBMPLUS release out Real Soon Now.) - -Of course, if you are working with 12-bit data, you probably have it stored -in some other, nonstandard format. In that case you'll probably want to -write your own I/O modules to read and write your format. - -Note that a 12-bit version of cjpeg always runs in "-optimize" mode, in -order to generate valid Huffman tables. This is necessary because our -default Huffman tables only cover 8-bit data. - -Removing code: - -If you need to make a smaller version of the JPEG software, some optional -functions can be removed at compile time. See the xxx_SUPPORTED #defines in -jconfig.h and jmorecfg.h. If at all possible, we recommend that you leave in -decoder support for all valid JPEG files, to ensure that you can read anyone's -output. Taking out support for image file formats that you don't use is the -most painless way to make the programs smaller. Another possibility is to -remove some of the DCT methods: in particular, the "IFAST" method may not be -enough faster than the others to be worth keeping on your machine. (If you -do remove ISLOW or IFAST, be sure to redefine JDCT_DEFAULT or JDCT_FASTEST -to a supported method, by adding a #define in jconfig.h.) - - -OPTIMIZATION -============ - -Unless you own a Cray, you'll probably be interested in making the JPEG -software go as fast as possible. This section covers some machine-dependent -optimizations you may want to try. We suggest that before trying any of -this, you first get the basic installation to pass the self-test step. -Repeat the self-test after any optimization to make sure that you haven't -broken anything. - -The integer DCT routines perform a lot of multiplications. These -multiplications must yield 32-bit results, but none of their input values -are more than 16 bits wide. On many machines, notably the 680x0 and 80x86 -CPUs, a 16x16=>32 bit multiply instruction is faster than a full 32x32=>32 -bit multiply. Unfortunately there is no portable way to specify such a -multiplication in C, but some compilers can generate one when you use the -right combination of casts. See the MULTIPLYxxx macro definitions in -jdct.h. If your compiler makes "int" be 32 bits and "short" be 16 bits, -defining SHORTxSHORT_32 is fairly likely to work. When experimenting with -alternate definitions, be sure to test not only whether the code still works -(use the self-test), but also whether it is actually faster --- on some -compilers, alternate definitions may compute the right answer, yet be slower -than the default. Timing cjpeg on a large PGM (grayscale) input file is the -best way to check this, as the DCT will be the largest fraction of the runtime -in that mode. (Note: some of the distributed compiler-specific jconfig files -already contain #define switches to select appropriate MULTIPLYxxx -definitions.) - -If your machine has sufficiently fast floating point hardware, you may find -that the float DCT method is faster than the integer DCT methods, even -after tweaking the integer multiply macros. In that case you may want to -make the float DCT be the default method. (The only objection to this is -that float DCT results may vary slightly across machines.) To do that, add -"#define JDCT_DEFAULT JDCT_FLOAT" to jconfig.h. Even if you don't change -the default, you should redefine JDCT_FASTEST, which is the method selected -by djpeg's -fast switch. Don't forget to update the documentation files -(usage.doc and/or cjpeg.1, djpeg.1) to agree with what you've done. - -If access to "short" arrays is slow on your machine, it may be a win to -define type JCOEF as int rather than short. This will cost a good deal of -memory though, particularly in some multi-pass modes, so don't do it unless -you have memory to burn and short is REALLY slow. - -If your compiler can compile function calls in-line, make sure the INLINE -macro in jmorecfg.h is defined as the keyword that marks a function -inline-able. Some compilers have a switch that tells the compiler to inline -any function it thinks is profitable (e.g., -finline-functions for gcc). -Enabling such a switch is likely to make the compiled code bigger but faster. - -In general, it's worth trying the maximum optimization level of your compiler, -and experimenting with any optional optimizations such as loop unrolling. -(Unfortunately, far too many compilers have optimizer bugs ... be prepared to -back off if the code fails self-test.) If you do any experimentation along -these lines, please report the optimal settings to jpeg-info@uunet.uu.net so -we can mention them in future releases. Be sure to specify your machine and -compiler version. - - -HINTS FOR SPECIFIC SYSTEMS -========================== - -We welcome reports on changes needed for systems not mentioned here. Submit -'em to jpeg-info@uunet.uu.net. Also, if configure or ckconfig.c is wrong -about how to configure the JPEG software for your system, please let us know. - - -Acorn RISC OS: - -(Thanks to Simon Middleton for these hints on compiling with Desktop C.) -After renaming the files according to Acorn conventions, take a copy of -makefile.ansi, change all occurrences of 'libjpeg.a' to 'libjpeg.o' and -change these definitions as indicated: - -CFLAGS= -throwback -IC: -Wn -LDLIBS=C:o.Stubs -SYSDEPMEM=jmemansi.o -LN=Link -AR=LibFile -c -o - -Also add a new line '.c.o:; $(cc) $< $(cflags) -c -o $@'. Remove the -lines '$(RM) libjpeg.o' and '$(AR2) libjpeg.o' and the 'jconfig.h' -dependency section. - -Copy jconfig.doc to jconfig.h. Edit jconfig.h to define TWO_FILE_COMMANDLINE -and CHAR_IS_UNSIGNED. - -Run the makefile using !AMU not !Make. If you want to use the 'clean' and -'test' makefile entries then you will have to fiddle with the syntax a bit -and rename the test files. - - -Amiga: - -SAS C 6.50 reportedly is too buggy to compile the IJG code properly. -A patch to update to 6.51 is available from SAS or AmiNet FTP sites. - -The supplied config files are set up to use jmemname.c as the memory -manager, with temporary files being created on the device named by -"JPEGTMP:". - - -Atari ST/STE/TT: - -Copy the project files makcjpeg.st, makdjpeg.st, maktjpeg.st, and makljpeg.st -to cjpeg.prj, djpeg.prj, jpegtran.prj, and libjpeg.prj respectively. The -project files should work as-is with Pure C. For Turbo C, change library -filenames "pc..." to "tc..." in each project file. Note that libjpeg.prj -selects jmemansi.c as the recommended memory manager. You'll probably want to -adjust the DEFAULT_MAX_MEM setting --- you want it to be a couple hundred K -less than your normal free memory. Put "#define DEFAULT_MAX_MEM nnnn" into -jconfig.h to do this. - -To use the 68881/68882 coprocessor for the floating point DCT, add the -compiler option "-8" to the project files and replace pcfltlib.lib with -pc881lib.lib in cjpeg.prj and djpeg.prj. Or if you don't have a -coprocessor, you may prefer to remove the float DCT code by undefining -DCT_FLOAT_SUPPORTED in jmorecfg.h (since without a coprocessor, the float -code will be too slow to be useful). In that case, you can delete -pcfltlib.lib from the project files. - -Note that you must make libjpeg.lib before making cjpeg.ttp, djpeg.ttp, -or jpegtran.ttp. You'll have to perform the self-test by hand. - -We haven't bothered to include project files for rdjpgcom and wrjpgcom. -Those source files should just be compiled by themselves; they don't -depend on the JPEG library. - -There is a bug in some older versions of the Turbo C library which causes the -space used by temporary files created with "tmpfile()" not to be freed after -an abnormal program exit. If you check your disk afterwards, you will find -cluster chains that are allocated but not used by a file. This should not -happen in cjpeg/djpeg/jpegtran, since we enable a signal catcher to explicitly -close temp files before exiting. But if you use the JPEG library with your -own code, be sure to supply a signal catcher, or else use a different -system-dependent memory manager. - - -Cray: - -Should you be so fortunate as to be running JPEG on a Cray YMP, there is a -compiler bug in old versions of Cray's Standard C (prior to 3.1). If you -still have an old compiler, you'll need to insert a line reading -"#pragma novector" just before the loop - for (i = 1; i <= (int) htbl->bits[l]; i++) - huffsize[p++] = (char) l; -in fix_huff_tbl (in V5beta1, line 204 of jchuff.c and line 176 of jdhuff.c). -[This bug may or may not still occur with the current IJG code, but it's -probably a dead issue anyway...] - - -HP-UX: - -If you have HP-UX 7.05 or later with the "software development" C compiler, -you should run the compiler in ANSI mode. If using the configure script, -say - ./configure CC='cc -Aa' -(or -Ae if you prefer). If configuring by hand, use makefile.ansi and add -"-Aa" to the CFLAGS line in the makefile. - -If you have a pre-7.05 system, or if you are using the non-ANSI C compiler -delivered with a minimum HP-UX system, then you must use makefile.unix -(and do NOT add -Aa); or just run configure without the CC option. - -On HP 9000 series 800 machines, the HP C compiler is buggy in revisions prior -to A.08.07. If you get complaints about "not a typedef name", you'll have to -use makefile.unix, or run configure without the CC option. - - -Macintosh, generic comments: - -The supplied user-interface files (cjpeg.c, djpeg.c, etc) are set up to -provide a Unix-style command line interface. You can use this interface on -the Mac by means of the ccommand() library routine provided by Metrowerks -CodeWarrior or Think C. This is only appropriate for testing the library, -however; to make a user-friendly equivalent of cjpeg/djpeg you'd really want -to develop a Mac-style user interface. There isn't a complete example -available at the moment, but there are some helpful starting points: -1. Sam Bushell's free "To JPEG" applet provides drag-and-drop conversion to -JPEG under System 7 and later. This only illustrates how to use the -compression half of the library, but it does a very nice job of that part. -The CodeWarrior source code is available from http://www.pobox.com/~jsam. -2. Jim Brunner prepared a Mac-style user interface for both compression and -decompression. Unfortunately, it hasn't been updated since IJG v4, and -the library's API has changed considerably since then. Still it may be of -some help, particularly as a guide to compiling the IJG code under Think C. -Jim's code is available from the Info-Mac archives, at sumex-aim.stanford.edu -or mirrors thereof; see file /info-mac/dev/src/jpeg-convert-c.hqx. - -jmemmac.c is the recommended memory manager back end for Macintosh. It uses -NewPtr/DisposePtr instead of malloc/free, and has a Mac-specific -implementation of jpeg_mem_available(). It also creates temporary files that -follow Mac conventions. (That part of the code relies on System-7-or-later OS -functions. See the comments in jmemmac.c if you need to run it on System 6.) -NOTE that USE_MAC_MEMMGR must be defined in jconfig.h to use jmemmac.c. - -You can also use jmemnobs.c, if you don't care about handling images larger -than available memory. If you use any memory manager back end other than -jmemmac.c, we recommend replacing "malloc" and "free" by "NewPtr" and -"DisposePtr", because Mac C libraries often have peculiar implementations of -malloc/free. (For instance, free() may not return the freed space to the -Mac Memory Manager. This is undesirable for the IJG code because jmemmgr.c -already clumps space requests.) - - -Macintosh, Metrowerks CodeWarrior: - -The Unix-command-line-style interface can be used by defining USE_CCOMMAND. -You'll also need to define TWO_FILE_COMMANDLINE to avoid stdin/stdout. -This means that when using the cjpeg/djpeg programs, you'll have to type the -input and output file names in the "Arguments" text-edit box, rather than -using the file radio buttons. (Perhaps USE_FDOPEN or USE_SETMODE would -eliminate the problem, but I haven't heard from anyone who's tried it.) - -On 680x0 Macs, Metrowerks defines type "double" as a 10-byte IEEE extended -float. jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power -of 2. Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint. - -The supplied configuration file jconfig.mac can be used for your jconfig.h; -it includes all the recommended symbol definitions. If you have AppleScript -installed, you can run the supplied script makeproj.mac to create CodeWarrior -project files for the library and the testbed applications, then build the -library and applications. (Thanks to Dan Sears and Don Agro for this nifty -hack, which saves us from trying to maintain CodeWarrior project files as part -of the IJG distribution...) - - -Macintosh, Think C: - -The documentation in Jim Brunner's "JPEG Convert" source code (see above) -includes detailed build instructions for Think C; it's probably somewhat -out of date for the current release, but may be helpful. - -If you want to build the minimal command line version, proceed as follows. -You'll have to prepare project files for the programs; we don't include any -in the distribution since they are not text files. Use the file lists in -any of the supplied makefiles as a guide. Also add the ANSI and Unix C -libraries in a separate segment. You may need to divide the JPEG files into -more than one segment; we recommend dividing compression and decompression -modules. Define USE_CCOMMAND in jconfig.h so that the ccommand() routine is -called. You must also define TWO_FILE_COMMANDLINE because stdin/stdout -don't handle binary data correctly. - -On 680x0 Macs, Think C defines type "double" as a 12-byte IEEE extended float. -jmemmgr.c won't like this: it wants sizeof(ALIGN_TYPE) to be a power of 2. -Add "#define ALIGN_TYPE long" to jconfig.h to eliminate the complaint. - -jconfig.mac should work as a jconfig.h configuration file for Think C, -but the makeproj.mac AppleScript script is specific to CodeWarrior. Sorry. - - -MIPS R3000: - -MIPS's cc version 1.31 has a rather nasty optimization bug. Don't use -O -if you have that compiler version. (Use "cc -V" to check the version.) -Note that the R3000 chip is found in workstations from DEC and others. - - -MS-DOS, generic comments for 16-bit compilers: - -The IJG code is designed to work well in 80x86 "small" or "medium" memory -models (i.e., data pointers are 16 bits unless explicitly declared "far"; -code pointers can be either size). You may be able to use small model to -compile cjpeg or djpeg by itself, but you will probably have to use medium -model for any larger application. This won't make much difference in -performance. You *will* take a noticeable performance hit if you use a -large-data memory model, and you should avoid "huge" model if at all -possible. Be sure that NEED_FAR_POINTERS is defined in jconfig.h if you use -a small-data memory model; be sure it is NOT defined if you use a large-data -model. (The supplied makefiles and jconfig files for Borland and Microsoft C -compile in medium model and define NEED_FAR_POINTERS.) - -The DOS-specific memory manager, jmemdos.c, should be used if possible. -It needs some assembly-code routines which are in jmemdosa.asm; make sure -your makefile assembles that file and includes it in the library. If you -don't have a suitable assembler, you can get pre-assembled object files for -jmemdosa by FTP from ftp.uu.net:/graphics/jpeg/jdosaobj.zip. (DOS-oriented -distributions of the IJG source code often include these object files.) - -When using jmemdos.c, jconfig.h must define USE_MSDOS_MEMMGR and must set -MAX_ALLOC_CHUNK to less than 64K (65520L is a typical value). If your -C library's far-heap malloc() can't allocate blocks that large, reduce -MAX_ALLOC_CHUNK to whatever it can handle. - -If you can't use jmemdos.c for some reason --- for example, because you -don't have an assembler to assemble jmemdosa.asm --- you'll have to fall -back to jmemansi.c or jmemname.c. You'll probably still need to set -MAX_ALLOC_CHUNK in jconfig.h, because most DOS C libraries won't malloc() -more than 64K at a time. IMPORTANT: if you use jmemansi.c or jmemname.c, -you will have to compile in a large-data memory model in order to get the -right stdio library. Too bad. - -wrjpgcom needs to be compiled in large model, because it malloc()s a 64KB -work area to hold the comment text. If your C library's malloc can't -handle that, reduce MAX_COM_LENGTH as necessary in wrjpgcom.c. - -Most MS-DOS compilers treat stdin/stdout as text files, so you must use -two-file command line style. But if your compiler has either fdopen() or -setmode(), you can use one-file style if you like. To do this, define -USE_SETMODE or USE_FDOPEN so that stdin/stdout will be set to binary mode. -(USE_SETMODE seems to work with more DOS compilers than USE_FDOPEN.) You -should test that I/O through stdin/stdout produces the same results as I/O -to explicitly named files... the "make test" procedures in the supplied -makefiles do NOT use stdin/stdout. - - -MS-DOS, generic comments for 32-bit compilers: - -None of the above comments about memory models apply if you are using a -32-bit flat-memory-space environment, such as DJGPP or Watcom C. (And you -should use one if you have it, as performance will be much better than -8086-compatible code!) For flat-memory-space compilers, do NOT define -NEED_FAR_POINTERS, and do NOT use jmemdos.c. Use jmemnobs.c if the -environment supplies adequate virtual memory, otherwise use jmemansi.c or -jmemname.c. - -You'll still need to be careful about binary I/O through stdin/stdout. -See the last paragraph of the previous section. - - -MS-DOS, Borland C: - -Be sure to convert all the source files to DOS text format (CR/LF newlines). -Although Borland C will often work OK with unmodified Unix (LF newlines) -source files, sometimes it will give bogus compile errors. -"Illegal character '#'" is the most common such error. (This is true with -Borland C 3.1, but perhaps is fixed in newer releases.) - -If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE. -jconfig.bcc already includes #define USE_SETMODE to make this work. -(fdopen does not work correctly.) - - -MS-DOS, Microsoft C: - -makefile.mc6 works with Microsoft C, DOS Visual C++, etc. It should only -be used if you want to build a 16-bit (small or medium memory model) program. - -If you want one-file command line style, just undefine TWO_FILE_COMMANDLINE. -jconfig.mc6 already includes #define USE_SETMODE to make this work. -(fdopen does not work correctly.) - -Note that this makefile assumes that the working copy of itself is called -"makefile". If you want to call it something else, say "makefile.mak", -be sure to adjust the dependency line that reads "$(RFILE) : makefile". -Otherwise the make will fail because it doesn't know how to create "makefile". -Worse, some releases of Microsoft's make utilities give an incorrect error -message in this situation. - -Old versions of MS C fail with an "out of macro expansion space" error -because they can't cope with the macro TRACEMS8 (defined in jerror.h). -If this happens to you, the easiest solution is to change TRACEMS8 to -expand to nothing. You'll lose the ability to dump out JPEG coefficient -tables with djpeg -debug -debug, but at least you can compile. - -Original MS C 6.0 is very buggy; it compiles incorrect code unless you turn -off optimization entirely (remove -O from CFLAGS). 6.00A is better, but it -still generates bad code if you enable loop optimizations (-Ol or -Ox). - -MS C 8.0 crashes when compiling jquant1.c with optimization switch /Oo ... -which is on by default. To work around this bug, compile that one file -with /Oo-. - - -Microsoft Windows (all versions), generic comments: - -Some Windows system include files define typedef boolean as "unsigned char". -The IJG code also defines typedef boolean, but we make it "int" by default. -This doesn't affect the IJG programs because we don't import those Windows -include files. But if you use the JPEG library in your own program, and some -of your program's files import one definition of boolean while some import the -other, you can get all sorts of mysterious problems. A good preventive step -is to make the IJG library use "unsigned char" for boolean. To do that, -add something like this to your jconfig.h file: - /* Define "boolean" as unsigned char, not int, per Windows custom */ - #ifndef __RPCNDR_H__ /* don't conflict if rpcndr.h already read */ - typedef unsigned char boolean; - #endif - #define HAVE_BOOLEAN /* prevent jmorecfg.h from redefining it */ -(This is already in jconfig.vc, by the way.) - -windef.h contains the declarations - #define far - #define FAR far -Since jmorecfg.h tries to define FAR as empty, you may get a compiler -warning if you include both jpeglib.h and windef.h (which windows.h -includes). To suppress the warning, you can put "#ifndef FAR"/"#endif" -around the line "#define FAR" in jmorecfg.h. - -When using the library in a Windows application, you will almost certainly -want to modify or replace the error handler module jerror.c, since our -default error handler does a couple of inappropriate things: - 1. it tries to write error and warning messages on stderr; - 2. in event of a fatal error, it exits by calling exit(). - -A simple stopgap solution for problem 1 is to replace the line - fprintf(stderr, "%s\n", buffer); -(in output_message in jerror.c) with - MessageBox(GetActiveWindow(),buffer,"JPEG Error",MB_OK|MB_ICONERROR); -It's highly recommended that you at least do that much, since otherwise -error messages will disappear into nowhere. (Beginning with IJG v6b, this -code is already present in jerror.c; just define USE_WINDOWS_MESSAGEBOX in -jconfig.h to enable it.) - -The proper solution for problem 2 is to return control to your calling -application after a library error. This can be done with the setjmp/longjmp -technique discussed in libjpeg.doc and illustrated in example.c. (NOTE: -some older Windows C compilers provide versions of setjmp/longjmp that -don't actually work under Windows. You may need to use the Windows system -functions Catch and Throw instead.) - -The recommended memory manager under Windows is jmemnobs.c; in other words, -let Windows do any virtual memory management needed. You should NOT use -jmemdos.c nor jmemdosa.asm under Windows. - -For Windows 3.1, we recommend compiling in medium or large memory model; -for newer Windows versions, use a 32-bit flat memory model. (See the MS-DOS -sections above for more info about memory models.) In the 16-bit memory -models only, you'll need to put - #define MAX_ALLOC_CHUNK 65520L /* Maximum request to malloc() */ -into jconfig.h to limit allocation chunks to 64Kb. (Without that, you'd -have to use huge memory model, which slows things down unnecessarily.) -jmemnobs.c works without modification in large or flat memory models, but to -use medium model, you need to modify its jpeg_get_large and jpeg_free_large -routines to allocate far memory. In any case, you might like to replace -its calls to malloc and free with direct calls on Windows memory allocation -functions. - -You may also want to modify jdatasrc.c and jdatadst.c to use Windows file -operations rather than fread/fwrite. This is only necessary if your C -compiler doesn't provide a competent implementation of C stdio functions. - -You might want to tweak the RGB_xxx macros in jmorecfg.h so that the library -will accept or deliver color pixels in BGR sample order, not RGB; BGR order -is usually more convenient under Windows. Note that this change will break -the sample applications cjpeg/djpeg, but the library itself works fine. - - -Many people want to convert the IJG library into a DLL. This is reasonably -straightforward, but watch out for the following: - - 1. Don't try to compile as a DLL in small or medium memory model; use -large model, or even better, 32-bit flat model. Many places in the IJG code -assume the address of a local variable is an ordinary (not FAR) pointer; -that isn't true in a medium-model DLL. - - 2. Microsoft C cannot pass file pointers between applications and DLLs. -(See Microsoft Knowledge Base, PSS ID Number Q50336.) So jdatasrc.c and -jdatadst.c don't work if you open a file in your application and then pass -the pointer to the DLL. One workaround is to make jdatasrc.c/jdatadst.c -part of your main application rather than part of the DLL. - - 3. You'll probably need to modify the macros GLOBAL() and EXTERN() to -attach suitable linkage keywords to the exported routine names. Similarly, -you'll want to modify METHODDEF() and JMETHOD() to ensure function pointers -are declared in a way that lets application routines be called back through -the function pointers. These macros are in jmorecfg.h. Typical definitions -for a 16-bit DLL are: - #define GLOBAL(type) type _far _pascal _loadds _export - #define EXTERN(type) extern type _far _pascal _loadds - #define METHODDEF(type) static type _far _pascal - #define JMETHOD(type,methodname,arglist) \ - type (_far _pascal *methodname) arglist -For a 32-bit DLL you may want something like - #define GLOBAL(type) __declspec(dllexport) type - #define EXTERN(type) extern __declspec(dllexport) type -Although not all the GLOBAL routines are actually intended to be called by -the application, the performance cost of making them all DLL entry points is -negligible. - -The unmodified IJG library presents a very C-specific application interface, -so the resulting DLL is only usable from C or C++ applications. There has -been some talk of writing wrapper code that would present a simpler interface -usable from other languages, such as Visual Basic. This is on our to-do list -but hasn't been very high priority --- any volunteers out there? - - -Microsoft Windows, Borland C: - -The provided jconfig.bcc should work OK in a 32-bit Windows environment, -but you'll need to tweak it in a 16-bit environment (you'd need to define -NEED_FAR_POINTERS and MAX_ALLOC_CHUNK). Beware that makefile.bcc will need -alteration if you want to use it for Windows --- in particular, you should -use jmemnobs.c not jmemdos.c under Windows. - -Borland C++ 4.5 fails with an internal compiler error when trying to compile -jdmerge.c in 32-bit mode. If enough people complain, perhaps Borland will fix -it.

(Are there -several different releases all numbered "4.5"??) - - -Microsoft Windows, Microsoft Visual C++: - -jconfig.vc should work OK with any Microsoft compiler for a 32-bit memory -model. makefile.vc is intended for command-line use. (If you are using -the Developer Studio environment, you may prefer the DevStudio project -files; see below.) - -Some users feel that it's easier to call the library from C++ code if you -force VC++ to treat the library as C++ code, which you can do by renaming -all the *.c files to *.cpp (and adjusting the makefile to match). This -avoids the need to put extern "C" { ... } around #include "jpeglib.h" in -your C++ application. - - -Microsoft Windows, Microsoft Developer Studio: - -We include makefiles that should work as project files in DevStudio 4.2 or -later.

Copy jconfig.vc to jconfig.h, makelib.ds to jpeg.mak, and - makeapps.ds to apps.mak. (Note that the renaming is critical!) -2. Click on the .mak files to construct project workspaces. - (If you are using DevStudio more recent than 4.2, you'll probably - get a message saying that the makefiles are being updated.) -3. Build the library project, then the applications project. -4. Move the application .exe files from `app`\Release to an - appropriate location on your path. -5. To perform the self-test, execute the command line - NMAKE /f makefile.vc test - - -OS/2, Borland C++: - -Watch out for optimization bugs in older Borland compilers; you may need -to back off the optimization switch settings.

Use it only if the make fails at the -stage of linking the completed programs. - -On the MIPS R4000 architecture (Indy, etc.), the compiler option "-mips2" -reportedly speeds up the float DCT method substantially, enough to make it -faster than the default int method (but still slower than the fast int -method). If you use -mips2, you may want to alter the default DCT method to -be float. To do this, put "#define JDCT_DEFAULT JDCT_FLOAT" in jconfig.h. - - -VMS: - -On an Alpha/VMS system with MMS, be sure to use the "/Marco=Alpha=1" -qualifier with MMS when building the JPEG package. - -VAX/VMS v5.5-1 may have problems with the test step of the build procedure -reporting differences when it compares the original and test images.

Nonetheless, the main controller is not - * trivial. Its responsibility is to provide context rows for upsampling/ - * rescaling, and doing this in an efficient fashion is a bit tricky. - * - * Postprocessor input data is counted in "row groups". A row group - * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size) - * sample rows of each component. (We require DCT_scaled_size values to be - * chosen such that these numbers are integers. In practice DCT_scaled_size - * values will likely be powers of two, so we actually have the stronger - * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.) - * Upsampling will typically produce max_v_samp_factor pixel rows from each - * row group (times any additional scale factor that the upsampler is - * applying). - * - * The coefficient controller will deliver data to us one iMCU row at a time; - * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or - * exactly min_DCT_scaled_size row groups. (This amount of data corresponds - * to one row of MCUs when the image is fully interleaved.) Note that the - * number of sample rows varies across components, but the number of row - * groups does not. Some garbage sample rows may be included in the last iMCU - * row at the bottom of the image. - * - * Depending on the vertical scaling algorithm used, the upsampler may need - * access to the sample row(s) above and below its current input row group. - * The upsampler is required to set need_context_rows TRUE at global selection - * time if so. When need_context_rows is FALSE, this controller can simply - * obtain one iMCU row at a time from the coefficient controller and dole it - * out as row groups to the postprocessor. - * - * When need_context_rows is TRUE, this controller guarantees that the buffer - * passed to postprocessing contains at least one row group's worth of samples - * above and below the row group(s) being processed. Note that the context - * rows "above" the first passed row group appear at negative row offsets in - * the passed buffer. At the top and bottom of the image, the required - * context rows are manufactured by duplicating the first or last real sample - * row; this avoids having special cases in the upsampling inner loops. - * - * The amount of context is fixed at one row group just because that's a - * convenient number for this controller to work with. The existing - * upsamplers really only need one sample row of context. An upsampler - * supporting arbitrary output rescaling might wish for more than one row - * group of context when shrinking the image; tough, we don't handle that. - * (This is justified by the assumption that downsizing will be handled mostly - * by adjusting the DCT_scaled_size values, so that the actual scale factor at - * the upsample step needn't be much less than one.) - * - * To provide the desired context, we have to retain the last two row groups - * of one iMCU row while reading in the next iMCU row. (The last row group - * can't be processed until we have another row group for its below-context, - * and so we have to save the next-to-last group too for its above-context.) - * We could do this most simply by copying data around in our buffer, but - * that'd be very slow. We can avoid copying any data by creating a rather - * strange pointer structure. Here's how it works. We allocate a workspace - * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number - * of row groups per iMCU row). We create two sets of redundant pointers to - * the workspace. Labeling the physical row groups 0 to M+1, the synthesized - * pointer lists look like this: - * M+1 M-1 - * master pointer --> 0 master pointer --> 0 - * 1 1 - * ... ... - * M-3 M-3 - * M-2 M - * M-1 M+1 - * M M-2 - * M+1 M-1 - * 0 0 - * We read alternate iMCU rows using each master pointer; thus the last two - * row groups of the previous iMCU row remain un-overwritten in the workspace. - * The pointer lists are set up so that the required context rows appear to - * be adjacent to the proper places when we pass the pointer lists to the - * upsampler. - * - * The above pictures describe the normal state of the pointer lists. - * At top and bottom of the image, we diddle the pointer lists to duplicate - * the first or last sample row as necessary (this is cheaper than copying - * sample rows around). - * - * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1. In that - * situation each iMCU row provides only one row group so the buffering logic - * must be different (eg, we must read two iMCU rows before we can emit the - * first row group). For now, we simply do not support providing context - * rows when min_DCT_scaled_size is 1.

Lane. - * This file is part of the Independent JPEG Group's software. - * For conditions of distribution and use, see the accompanying README file. - * - * This file contains a floating-point implementation of the - * forward DCT (Discrete Cosine Transform). - * - * This implementation should be more accurate than either of the integer - * DCT implementations. However, it may not give the same results on all - * machines because of differences in roundoff behavior. Speed will depend - * on the hardware's floating point capacity. - * - * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT - * on each column. Direct algorithms are also available, but they are - * much more complex and seem not to be any faster when reduced to code. - * - * This implementation is based on Arai, Agui, and Nakajima's algorithm for - * scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in - * Japanese, but the algorithm is described in the Pennebaker & Mitchell - * JPEG textbook (see REFERENCES section in file README). The following code - * is based directly on figure 4-8 in P&M. - * While an 8-point DCT cannot be done in less than 11 multiplies, it is - * possible to arrange the computation so that many of the multiplies are - * simple scalings of the final outputs.

Full-image-sized buffers - * are handled as "virtual" arrays. The array is still accessed a strip at a - * time, but the memory manager must save the whole array for repeated - * accesses. The intended implementation is that there is a strip buffer in - * memory (as high as is possible given the desired memory limit), plus a - * backing file that holds the rest of the array. - * - * The request_virt_array routines are told the total size of the image and - * the maximum number of rows that will be accessed at once. The in-memory - * buffer must be at least as large as the maxaccess value. - * - * The request routines create control blocks but not the in-memory buffers. - * That is postponed until realize_virt_arrays is called. At that time the - * total amount of space needed is known (approximately, anyway), so free - * memory can be divided up fairly. - * - * The access_virt_array routines are responsible for making a specific strip - * area accessible (after reading or writing the backing file, if necessary). - * Note that the access routines are told whether the caller intends to modify - * the accessed strip; during a read-only pass this saves having to rewrite - * data to disk.

It can also -perform some rearrangements of the image data, for example turning an image -from landscape to portrait format by rotation. -.PP -.B jpegtran -works by rearranging the compressed data (DCT coefficients), without -ever fully decoding the image. Therefore, its transformations are lossless: -there is no image degradation at all, which would not be true if you used -.B djpeg -followed by -.B cjpeg -to accomplish the same conversion. But by the same token, -.B jpegtran -cannot perform lossy operations such as changing the image quality. -.PP -.B jpegtran -reads the named JPEG/JFIF file, or the standard input if no file is -named, and produces a JPEG/JFIF file on the standard output. -.SH OPTIONS -All switch names may be abbreviated; for example, -.B \-optimize -may be written -.B \-opt -or -.BR \-o . -Upper and lower case are equivalent. -British spellings are also accepted (e.g., -.BR \-optimise ), -though for brevity these are not mentioned below. -.PP -To specify the coded JPEG representation used in the output file, -.B jpegtran -accepts a subset of the switches recognized by -.BR cjpeg : -.TP -.B \-optimize -Perform optimization of entropy encoding parameters. -.TP -.B \-progressive -Create progressive JPEG file. -.TP -.BI \-restart " N" -Emit a JPEG restart marker every N MCU rows, or every N MCU blocks if "B" is -attached to the number. -.TP -.BI \-scans " file" -Use the scan script given in the specified text file. -.PP -See -.BR cjpeg (1) -for more details about these switches. -If you specify none of these switches, you get a plain baseline-JPEG output -file. The quality setting and so forth are determined by the input file. -.PP -The image can be losslessly transformed by giving one of these switches: -.TP -.B \-flip horizontal -Mirror image horizontally (left-right). -.TP -.B \-flip vertical -Mirror image vertically (top-bottom). -.TP -.B \-rotate 90 -Rotate image 90 degrees clockwise. -.TP -.B \-rotate 180 -Rotate image 180 degrees. -.TP -.B \-rotate 270 -Rotate image 270 degrees clockwise (or 90 ccw). -.TP -.B \-transpose -Transpose image (across UL-to-LR axis). -.TP -.B \-transverse -Transverse transpose (across UR-to-LL axis). -.PP -The transpose transformation has no restrictions regarding image dimensions. -The other transformations operate rather oddly if the image dimensions are not -a multiple of the iMCU size (usually 8 or 16 pixels), because they can only -transform complete blocks of DCT coefficient data in the desired way. -.PP -.BR jpegtran 's -default behavior when transforming an odd-size image is designed -to preserve exact reversibility and mathematical consistency of the -transformation set. As stated, transpose is able to flip the entire image -area. Horizontal mirroring leaves any partial iMCU column at the right edge -untouched, but is able to flip all rows of the image. Similarly, vertical -mirroring leaves any partial iMCU row at the bottom edge untouched, but is -able to flip all columns. The other transforms can be built up as sequences -of transpose and flip operations; for consistency, their actions on edge -pixels are defined to be the same as the end result of the corresponding -transpose-and-flip sequence. -.PP -For practical use, you may prefer to discard any untransformable edge pixels -rather than having a strange-looking strip along the right and/or bottom edges -of a transformed image. To do this, add the -.B \-trim -switch: -.TP -.B \-trim -Drop non-transformable edge blocks. -.PP -Obviously, a transformation with -.B \-trim -is not reversible, so strictly speaking -.B jpegtran -with this switch is not lossless. Also, the expected mathematical -equivalences between the transformations no longer hold. For example, -.B \-rot 270 -trim -trims only the bottom edge, but -.B \-rot 90 -trim -followed by -.B \-rot 180 -trim -trims both edges. -.PP -Another not-strictly-lossless transformation switch is: -.TP -.B \-grayscale -Force grayscale output. -.PP -This option discards the chrominance channels if the input image is YCbCr -(ie, a standard color JPEG), resulting in a grayscale JPEG file. The -luminance channel is preserved exactly, so this is a better method of reducing -to grayscale than decompression, conversion, and recompression. This switch -is particularly handy for fixing a monochrome picture that was mistakenly -encoded as a color JPEG. (In such a case, the space savings from getting rid -of the near-empty chroma channels won't be large; but the decoding time for -a grayscale JPEG is substantially less than that for a color JPEG.) -.PP -.B jpegtran -also recognizes these switches that control what to do with "extra" markers, -such as comment blocks: -.TP -.B \-copy none -Copy no extra markers from source file. This setting suppresses all -comments and other excess baggage present in the source file. -.TP -.B \-copy comments -Copy only comment markers. This setting copies comments from the source file, -but discards any other inessential data. -.TP -.B \-copy all -Copy all extra markers. This setting preserves miscellaneous markers -found in the source file, such as JFIF thumbnails and Photoshop settings. -In some files these extra markers can be sizable. -.PP -The default behavior is -.BR "\-copy comments" . -(Note: in IJG releases v6 and v6a, -.B jpegtran -always did the equivalent of -.BR "\-copy none" .) -.PP -Additional switches recognized by jpegtran are: -.TP -.BI \-maxmemory " N" -Set limit for amount of memory to use in processing large images. Value is -in thousands of bytes, or millions of bytes if "M" is attached to the -number. For example, -.B \-max 4m -selects 4000000 bytes. If more space is needed, temporary files will be used. -.TP -.BI \-outfile " name" -Send output image to the named file, not to standard output. -.TP -.B \-verbose -Enable debug printout. More -.BR \-v 's -give more output. Also, version information is printed at startup. -.TP -.B \-debug -Same as -.BR \-verbose . -.SH EXAMPLES -.LP -This example converts a baseline JPEG file to progressive form: -.IP -.B jpegtran \-progressive -.I foo.jpg -.B > -.I fooprog.jpg -.PP -This example rotates an image 90 degrees clockwise, discarding any -unrotatable edge pixels: -.IP -.B jpegtran \-rot 90 -trim -.I foo.jpg -.B > -.I foo90.jpg -.SH ENVIRONMENT -.TP -.B JPEGMEM -If this environment variable is set, its value is the default memory limit. -The value is specified as described for the -.B \-maxmemory -switch. -.B JPEGMEM -overrides the default value specified when the program was compiled, and -itself is overridden by an explicit -.BR \-maxmemory . -.SH SEE ALSO -.BR cjpeg (1), -.BR djpeg (1), -.BR rdjpgcom (1), -.BR wrjpgcom (1) -.br -Wallace, Gregory K.

This may not be quite the closest entry to - * the actual input color, but it's almost as good.

When we find the - * nearest color for a cell, its colormap index plus one is recorded in the - * cache for future use. The pass2 scanning routines call fill_inverse_cmap - * when they need to use an unfilled entry in the cache. - * - * Our method of efficiently finding nearest colors is based on the "locally - * sorted search" idea described by Heckbert and on the incremental distance - * calculation described by Spencer W. Thomas in chapter III.1 of Graphics - * Gems II (James Arvo, ed. Academic Press, 1991). Thomas points out that - * the distances from a given colormap entry to each cell of the histogram can - * be computed quickly using an incremental method: the differences between - * distances to adjacent cells themselves differ by a constant. This allows a - * fairly fast implementation of the "brute force" approach of computing the - * distance from every colormap entry to every histogram cell. Unfortunately, - * it needs a work array to hold the best-distance-so-far for each histogram - * cell (because the inner loop has to be over cells, not colormap entries). - * The work array elements have to be INT32s, so the work array would need - * 256Kb at our recommended precision. This is not feasible in DOS machines. - * - * To get around these problems, we apply Thomas' method to compute the - * nearest colors for only the cells within a small subbox of the histogram. - * The work array need be only as big as the subbox, so the memory usage - * problem is solved. Furthermore, we need not fill subboxes that are never - * referenced in pass2; many images use only part of the color gamut, so a - * fair amount of work is saved. An additional advantage of this - * approach is that we can apply Heckbert's locality criterion to quickly - * eliminate colormap entries that are far away from the subbox; typically - * three-fourths of the colormap entries are rejected by Heckbert's criterion, - * and we need not compute their distances to individual cells in the subbox. - * The speed of this approach is heavily influenced by the subbox size: too - * small means too much overhead, too big loses because Heckbert's criterion - * can't eliminate as many colormap entries. Empirically the best subbox - * size seems to be about 1/512th of the histogram (1/8th in each direction). - * - * Thomas' article also describes a refined method which is asymptotically - * faster than the brute-force method, but it is also far more complex and - * cannot efficiently be applied to small subboxes.

The sections on advanced features can be read -if and when you need them. - - -OVERVIEW -======== - -Functions provided by the library ---------------------------------- - -The IJG JPEG library provides C code to read and write JPEG-compressed image -files. The surrounding application program receives or supplies image data a -scanline at a time, using a straightforward uncompressed image format. All -details of color conversion and other preprocessing/postprocessing can be -handled by the library. - -The library includes a substantial amount of code that is not covered by the -JPEG standard but is necessary for typical applications of JPEG. These -functions preprocess the image before JPEG compression or postprocess it after -decompression. They include colorspace conversion, downsampling/upsampling, -and color quantization. The application indirectly selects use of this code -by specifying the format in which it wishes to supply or receive image data. -For example, if colormapped output is requested, then the decompression -library automatically invokes color quantization. - -A wide range of quality vs. speed tradeoffs are possible in JPEG processing, -and even more so in decompression postprocessing. The decompression library -provides multiple implementations that cover most of the useful tradeoffs, -ranging from very-high-quality down to fast-preview operation. On the -compression side we have generally not provided low-quality choices, since -compression is normally less time-critical. It should be understood that the -low-quality modes may not meet the JPEG standard's accuracy requirements; -nonetheless, they are useful for viewers. - -A word about functions *not* provided by the library. We handle a subset of -the ISO JPEG standard; most baseline, extended-sequential, and progressive -JPEG processes are supported. (Our subset includes all features now in common -use.) Unsupported ISO options include: - * Hierarchical storage - * Lossless JPEG - * Arithmetic entropy coding (unsupported for legal reasons) - * DNL marker - * Nonintegral subsampling ratios -We support both 8- and 12-bit data precision, but this is a compile-time -choice rather than a run-time choice; hence it is difficult to use both -precisions in a single application. - -By itself, the library handles only interchange JPEG datastreams --- in -particular the widely used JFIF file format. The library can be used by -surrounding code to process interchange or abbreviated JPEG datastreams that -are embedded in more complex file formats. (For example, this library is -used by the free LIBTIFF library to support JPEG compression in TIFF.) - - -Outline of typical usage ------------------------- - -The rough outline of a JPEG compression operation is: - - Allocate and initialize a JPEG compression object - Specify the destination for the compressed data (eg, a file) - Set parameters for compression, including image size & colorspace - jpeg_start_compress(...); - while (scan lines remain to be written) - jpeg_write_scanlines(...); - jpeg_finish_compress(...); - Release the JPEG compression object - -A JPEG compression object holds parameters and working state for the JPEG -library. We make creation/destruction of the object separate from starting -or finishing compression of an image; the same object can be re-used for a -series of image compression operations. This makes it easy to re-use the -same parameter settings for a sequence of images. Re-use of a JPEG object -also has important implications for processing abbreviated JPEG datastreams, -as discussed later. - -The image data to be compressed is supplied to jpeg_write_scanlines() from -in-memory buffers. If the application is doing file-to-file compression, -reading image data from the source file is the application's responsibility. -The library emits compressed data by calling a "data destination manager", -which typically will write the data into a file; but the application can -provide its own destination manager to do something else. - -Similarly, the rough outline of a JPEG decompression operation is: - - Allocate and initialize a JPEG decompression object - Specify the source of the compressed data (eg, a file) - Call jpeg_read_header() to obtain image info - Set parameters for decompression - jpeg_start_decompress(...); - while (scan lines remain to be read) - jpeg_read_scanlines(...); - jpeg_finish_decompress(...); - Release the JPEG decompression object - -This is comparable to the compression outline except that reading the -datastream header is a separate step. This is helpful because information -about the image's size, colorspace, etc is available when the application -selects decompression parameters. For example, the application can choose an -output scaling ratio that will fit the image into the available screen size. - -The decompression library obtains compressed data by calling a data source -manager, which typically will read the data from a file; but other behaviors -can be obtained with a custom source manager. Decompressed data is delivered -into in-memory buffers passed to jpeg_read_scanlines(). - -It is possible to abort an incomplete compression or decompression operation -by calling jpeg_abort(); or, if you do not need to retain the JPEG object, -simply release it by calling jpeg_destroy(). - -JPEG compression and decompression objects are two separate struct types. -However, they share some common fields, and certain routines such as -jpeg_destroy() can work on either type of object. - -The JPEG library has no static variables: all state is in the compression -or decompression object. Therefore it is possible to process multiple -compression and decompression operations concurrently, using multiple JPEG -objects. - -Both compression and decompression can be done in an incremental memory-to- -memory fashion, if suitable source/destination managers are used. See the -section on "I/O suspension" for more details. - - -BASIC LIBRARY USAGE -=================== - -Data formats ------------- - -Before diving into procedural details, it is helpful to understand the -image data format that the JPEG library expects or returns. - -The standard input image format is a rectangular array of pixels, with each -pixel having the same number of "component" or "sample" values (color -channels). You must specify how many components there are and the colorspace -interpretation of the components. Most applications will use RGB data -(three components per pixel) or grayscale data (one component per pixel). -PLEASE NOTE THAT RGB DATA IS THREE SAMPLES PER PIXEL, GRAYSCALE ONLY ONE. -A remarkable number of people manage to miss this, only to find that their -programs don't work with grayscale JPEG files. - -There is no provision for colormapped input. JPEG files are always full-color -or full grayscale (or sometimes another colorspace such as CMYK). You can -feed in a colormapped image by expanding it to full-color format. However -JPEG often doesn't work very well with source data that has been colormapped, -because of dithering noise. This is discussed in more detail in the JPEG FAQ -and the other references mentioned in the README file. - -Pixels are stored by scanlines, with each scanline running from left to -right. The component values for each pixel are adjacent in the row; for -example, R,G,B,R,G,B,R,G,B,... for 24-bit RGB color. Each scanline is an -array of data type JSAMPLE --- which is typically "unsigned char", unless -you've changed jmorecfg.h. (You can also change the RGB pixel layout, say -to B,G,R order, by modifying jmorecfg.h. But see the restrictions listed in -that file before doing so.) - -A 2-D array of pixels is formed by making a list of pointers to the starts of -scanlines; so the scanlines need not be physically adjacent in memory. Even -if you process just one scanline at a time, you must make a one-element -pointer array to conform to this structure. Pointers to JSAMPLE rows are of -type JSAMPROW, and the pointer to the pointer array is of type JSAMPARRAY. - -The library accepts or supplies one or more complete scanlines per call. -It is not possible to process part of a row at a time. Scanlines are always -processed top-to-bottom. You can process an entire image in one call if you -have it all in memory, but usually it's simplest to process one scanline at -a time. - -For best results, source data values should have the precision specified by -BITS_IN_JSAMPLE (normally 8 bits). For instance, if you choose to compress -data that's only 6 bits/channel, you should left-justify each value in a -byte before passing it to the compressor. If you need to compress data -that has more than 8 bits/channel, compile with BITS_IN_JSAMPLE = 12. -(See "Library compile-time options", later.) - - -The data format returned by the decompressor is the same in all details, -except that colormapped output is supported. (Again, a JPEG file is never -colormapped. But you can ask the decompressor to perform on-the-fly color -quantization to deliver colormapped output.) If you request colormapped -output then the returned data array contains a single JSAMPLE per pixel; -its value is an index into a color map. The color map is represented as -a 2-D JSAMPARRAY in which each row holds the values of one color component, -that is, colormap[i][j] is the value of the i'th color component for pixel -value (map index) j. Note that since the colormap indexes are stored in -JSAMPLEs, the maximum number of colors is limited by the size of JSAMPLE -(ie, at most 256 colors for an 8-bit JPEG library). - - -Compression details -------------------- - -Here we revisit the JPEG compression outline given in the overview. - -1. Allocate and initialize a JPEG compression object. - -A JPEG compression object is a "struct jpeg_compress_struct". (It also has -a bunch of subsidiary structures which are allocated via malloc(), but the -application doesn't control those directly.) This struct can be just a local -variable in the calling routine, if a single routine is going to execute the -whole JPEG compression sequence. Otherwise it can be static or allocated -from malloc(). - -You will also need a structure representing a JPEG error handler. The part -of this that the library cares about is a "struct jpeg_error_mgr". If you -are providing your own error handler, you'll typically want to embed the -jpeg_error_mgr struct in a larger structure; this is discussed later under -"Error handling". For now we'll assume you are just using the default error -handler. The default error handler will print JPEG error/warning messages -on stderr, and it will call exit() if a fatal error occurs. - -You must initialize the error handler structure, store a pointer to it into -the JPEG object's "err" field, and then call jpeg_create_compress() to -initialize the rest of the JPEG object. - -Typical code for this step, if you are using the default error handler, is - - struct jpeg_compress_struct cinfo; - struct jpeg_error_mgr jerr; - ... - cinfo.err = jpeg_std_error(&jerr); - jpeg_create_compress(&cinfo); - -jpeg_create_compress allocates a small amount of memory, so it could fail -if you are out of memory. In that case it will exit via the error handler; -that's why the error handler must be initialized first. - - -2. Specify the destination for the compressed data (eg, a file). - -As previously mentioned, the JPEG library delivers compressed data to a -"data destination" module. The library includes one data destination -module which knows how to write to a stdio stream. You can use your own -destination module if you want to do something else, as discussed later. - -If you use the standard destination module, you must open the target stdio -stream beforehand. Typical code for this step looks like: - - FILE * outfile; - ... - if ((outfile = fopen(filename, "wb")) == NULL) { - fprintf(stderr, "can't open %s\n", filename); - exit(1); - } - jpeg_stdio_dest(&cinfo, outfile); - -where the last line invokes the standard destination module. - -WARNING: it is critical that the binary compressed data be delivered to the -output file unchanged. On non-Unix systems the stdio library may perform -newline translation or otherwise corrupt binary data. To suppress this -behavior, you may need to use a "b" option to fopen (as shown above), or use -setmode() or another routine to put the stdio stream in binary mode. See -cjpeg.c and djpeg.c for code that has been found to work on many systems. - -You can select the data destination after setting other parameters (step 3), -if that's more convenient. You may not change the destination between -calling jpeg_start_compress() and jpeg_finish_compress(). - - -3. Set parameters for compression, including image size & colorspace. - -You must supply information about the source image by setting the following -fields in the JPEG object (cinfo structure): - - image_width Width of image, in pixels - image_height Height of image, in pixels - input_components Number of color channels (samples per pixel) - in_color_space Color space of source image - -The image dimensions are, hopefully, obvious. JPEG supports image dimensions -of 1 to 64K pixels in either direction. The input color space is typically -RGB or grayscale, and input_components is 3 or 1 accordingly. (See "Special -color spaces", later, for more info.) The in_color_space field must be -assigned one of the J_COLOR_SPACE enum constants, typically JCS_RGB or -JCS_GRAYSCALE. - -JPEG has a large number of compression parameters that determine how the -image is encoded. Most applications don't need or want to know about all -these parameters. You can set all the parameters to reasonable defaults by -calling jpeg_set_defaults(); then, if there are particular values you want -to change, you can do so after that. The "Compression parameter selection" -section tells about all the parameters. - -You must set in_color_space correctly before calling jpeg_set_defaults(), -because the defaults depend on the source image colorspace. However the -other three source image parameters need not be valid until you call -jpeg_start_compress(). There's no harm in calling jpeg_set_defaults() more -than once, if that happens to be convenient. - -Typical code for a 24-bit RGB source image is - - cinfo.image_width = Width; /* image width and height, in pixels */ - cinfo.image_height = Height; - cinfo.input_components = 3; /* # of color components per pixel */ - cinfo.in_color_space = JCS_RGB; /* colorspace of input image */ - - jpeg_set_defaults(&cinfo); - /* Make optional parameter settings here */ - - -4. jpeg_start_compress(...); - -After you have established the data destination and set all the necessary -source image info and other parameters, call jpeg_start_compress() to begin -a compression cycle. This will initialize internal state, allocate working -storage, and emit the first few bytes of the JPEG datastream header. - -Typical code: - - jpeg_start_compress(&cinfo, TRUE); - -The "TRUE" parameter ensures that a complete JPEG interchange datastream -will be written. This is appropriate in most cases. If you think you might -want to use an abbreviated datastream, read the section on abbreviated -datastreams, below. - -Once you have called jpeg_start_compress(), you may not alter any JPEG -parameters or other fields of the JPEG object until you have completed -the compression cycle. - - -5. while (scan lines remain to be written) - jpeg_write_scanlines(...); - -Now write all the required image data by calling jpeg_write_scanlines() -one or more times. You can pass one or more scanlines in each call, up -to the total image height. In most applications it is convenient to pass -just one or a few scanlines at a time. The expected format for the passed -data is discussed under "Data formats", above. - -Image data should be written in top-to-bottom scanline order. The JPEG spec -contains some weasel wording about how top and bottom are application-defined -terms (a curious interpretation of the English language...) but if you want -your files to be compatible with everyone else's, you WILL use top-to-bottom -order. If the source data must be read in bottom-to-top order, you can use -the JPEG library's virtual array mechanism to invert the data efficiently. -Examples of this can be found in the sample application cjpeg. - -The library maintains a count of the number of scanlines written so far -in the next_scanline field of the JPEG object. Usually you can just use -this variable as the loop counter, so that the loop test looks like -"while (cinfo.next_scanline < cinfo.image_height)". - -Code for this step depends heavily on the way that you store the source data. -example.c shows the following code for the case of a full-size 2-D source -array containing 3-byte RGB pixels: - - JSAMPROW row_pointer[1]; /* pointer to a single row */ - int row_stride; /* physical row width in buffer */ - - row_stride = image_width * 3; /* JSAMPLEs per row in image_buffer */ - - while (cinfo.next_scanline < cinfo.image_height) { - row_pointer[0] = & image_buffer[cinfo.next_scanline * row_stride]; - jpeg_write_scanlines(&cinfo, row_pointer, 1); - } - -jpeg_write_scanlines() returns the number of scanlines actually written. -This will normally be equal to the number passed in, so you can usually -ignore the return value. It is different in just two cases: - * If you try to write more scanlines than the declared image height, - the additional scanlines are ignored. - * If you use a suspending data destination manager, output buffer overrun - will cause the compressor to return before accepting all the passed lines. - This feature is discussed under "I/O suspension", below. The normal - stdio destination manager will NOT cause this to happen. -In any case, the return value is the same as the change in the value of -next_scanline. - - -6. jpeg_finish_compress(...); - -After all the image data has been written, call jpeg_finish_compress() to -complete the compression cycle. This step is ESSENTIAL to ensure that the -last bufferload of data is written to the data destination. -jpeg_finish_compress() also releases working memory associated with the JPEG -object. - -Typical code: - - jpeg_finish_compress(&cinfo); - -If using the stdio destination manager, don't forget to close the output -stdio stream (if necessary) afterwards. - -If you have requested a multi-pass operating mode, such as Huffman code -optimization, jpeg_finish_compress() will perform the additional passes using -data buffered by the first pass. In this case jpeg_finish_compress() may take -quite a while to complete. With the default compression parameters, this will -not happen. - -It is an error to call jpeg_finish_compress() before writing the necessary -total number of scanlines. If you wish to abort compression, call -jpeg_abort() as discussed below. - -After completing a compression cycle, you may dispose of the JPEG object -as discussed next, or you may use it to compress another image. In that case -return to step 2, 3, or 4 as appropriate. If you do not change the -destination manager, the new datastream will be written to the same target. -If you do not change any JPEG parameters, the new datastream will be written -with the same parameters as before. Note that you can change the input image -dimensions freely between cycles, but if you change the input colorspace, you -should call jpeg_set_defaults() to adjust for the new colorspace; and then -you'll need to repeat all of step 3. - - -7. Release the JPEG compression object. - -When you are done with a JPEG compression object, destroy it by calling -jpeg_destroy_compress(). This will free all subsidiary memory (regardless of -the previous state of the object). Or you can call jpeg_destroy(), which -works for either compression or decompression objects --- this may be more -convenient if you are sharing code between compression and decompression -cases. (Actually, these routines are equivalent except for the declared type -of the passed pointer. To avoid gripes from ANSI C compilers, jpeg_destroy() -should be passed a j_common_ptr.) - -If you allocated the jpeg_compress_struct structure from malloc(), freeing -it is your responsibility --- jpeg_destroy() won't. Ditto for the error -handler structure. - -Typical code: - - jpeg_destroy_compress(&cinfo); - - -8. Aborting. - -If you decide to abort a compression cycle before finishing, you can clean up -in either of two ways: - -* If you don't need the JPEG object any more, just call - jpeg_destroy_compress() or jpeg_destroy() to release memory. This is - legitimate at any point after calling jpeg_create_compress() --- in fact, - it's safe even if jpeg_create_compress() fails. - -* If you want to re-use the JPEG object, call jpeg_abort_compress(), or call - jpeg_abort() which works on both compression and decompression objects. - This will return the object to an idle state, releasing any working memory. - jpeg_abort() is allowed at any time after successful object creation. - -Note that cleaning up the data destination, if required, is your -responsibility; neither of these routines will call term_destination(). -(See "Compressed data handling", below, for more about that.) - -jpeg_destroy() and jpeg_abort() are the only safe calls to make on a JPEG -object that has reported an error by calling error_exit (see "Error handling" -for more info). The internal state of such an object is likely to be out of -whack. Either of these two routines will return the object to a known state. - - -Decompression details ---------------------- - -Here we revisit the JPEG decompression outline given in the overview. - -1. Allocate and initialize a JPEG decompression object. - -This is just like initialization for compression, as discussed above, -except that the object is a "struct jpeg_decompress_struct" and you -call jpeg_create_decompress(). Error handling is exactly the same. - -Typical code: - - struct jpeg_decompress_struct cinfo; - struct jpeg_error_mgr jerr; - ... - cinfo.err = jpeg_std_error(&jerr); - jpeg_create_decompress(&cinfo); - -(Both here and in the IJG code, we usually use variable name "cinfo" for -both compression and decompression objects.) - - -2. Specify the source of the compressed data (eg, a file). - -As previously mentioned, the JPEG library reads compressed data from a "data -source" module. The library includes one data source module which knows how -to read from a stdio stream. You can use your own source module if you want -to do something else, as discussed later. - -If you use the standard source module, you must open the source stdio stream -beforehand. Typical code for this step looks like: - - FILE * infile; - ... - if ((infile = fopen(filename, "rb")) == NULL) { - fprintf(stderr, "can't open %s\n", filename); - exit(1); - } - jpeg_stdio_src(&cinfo, infile); - -where the last line invokes the standard source module. - -WARNING: it is critical that the binary compressed data be read unchanged. -On non-Unix systems the stdio library may perform newline translation or -otherwise corrupt binary data. To suppress this behavior, you may need to use -a "b" option to fopen (as shown above), or use setmode() or another routine to -put the stdio stream in binary mode. See cjpeg.c and djpeg.c for code that -has been found to work on many systems. - -You may not change the data source between calling jpeg_read_header() and -jpeg_finish_decompress(). If you wish to read a series of JPEG images from -a single source file, you should repeat the jpeg_read_header() to -jpeg_finish_decompress() sequence without reinitializing either the JPEG -object or the data source module; this prevents buffered input data from -being discarded. - - -3. Call jpeg_read_header() to obtain image info. - -Typical code for this step is just - - jpeg_read_header(&cinfo, TRUE); - -This will read the source datastream header markers, up to the beginning -of the compressed data proper. On return, the image dimensions and other -info have been stored in the JPEG object. The application may wish to -consult this information before selecting decompression parameters. - -More complex code is necessary if - * A suspending data source is used --- in that case jpeg_read_header() - may return before it has read all the header data. See "I/O suspension", - below. The normal stdio source manager will NOT cause this to happen. - * Abbreviated JPEG files are to be processed --- see the section on - abbreviated datastreams. Standard applications that deal only in - interchange JPEG files need not be concerned with this case either. - -It is permissible to stop at this point if you just wanted to find out the -image dimensions and other header info for a JPEG file. In that case, -call jpeg_destroy() when you are done with the JPEG object, or call -jpeg_abort() to return it to an idle state before selecting a new data -source and reading another header. - - -4. Set parameters for decompression. - -jpeg_read_header() sets appropriate default decompression parameters based on -the properties of the image (in particular, its colorspace). However, you -may well want to alter these defaults before beginning the decompression. -For example, the default is to produce full color output from a color file. -If you want colormapped output you must ask for it. Other options allow the -returned image to be scaled and allow various speed/quality tradeoffs to be -selected. "Decompression parameter selection", below, gives details. - -If the defaults are appropriate, nothing need be done at this step. - -Note that all default values are set by each call to jpeg_read_header(). -If you reuse a decompression object, you cannot expect your parameter -settings to be preserved across cycles, as you can for compression. -You must set desired parameter values each time. - - -5. jpeg_start_decompress(...); - -Once the parameter values are satisfactory, call jpeg_start_decompress() to -begin decompression. This will initialize internal state, allocate working -memory, and prepare for returning data. - -Typical code is just - - jpeg_start_decompress(&cinfo); - -If you have requested a multi-pass operating mode, such as 2-pass color -quantization, jpeg_start_decompress() will do everything needed before data -output can begin. In this case jpeg_start_decompress() may take quite a while -to complete. With a single-scan (non progressive) JPEG file and default -decompression parameters, this will not happen; jpeg_start_decompress() will -return quickly. - -After this call, the final output image dimensions, including any requested -scaling, are available in the JPEG object; so is the selected colormap, if -colormapped output has been requested. Useful fields include - - output_width image width and height, as scaled - output_height - out_color_components # of color components in out_color_space - output_components # of color components returned per pixel - colormap the selected colormap, if any - actual_number_of_colors number of entries in colormap - -output_components is 1 (a colormap index) when quantizing colors; otherwise it -equals out_color_components. It is the number of JSAMPLE values that will be -emitted per pixel in the output arrays. - -Typically you will need to allocate data buffers to hold the incoming image. -You will need output_width * output_components JSAMPLEs per scanline in your -output buffer, and a total of output_height scanlines will be returned. - -Note: if you are using the JPEG library's internal memory manager to allocate -data buffers (as djpeg does), then the manager's protocol requires that you -request large buffers *before* calling jpeg_start_decompress(). This is a -little tricky since the output_XXX fields are not normally valid then. You -can make them valid by calling jpeg_calc_output_dimensions() after setting the -relevant parameters (scaling, output color space, and quantization flag). - - -6. while (scan lines remain to be read) - jpeg_read_scanlines(...); - -Now you can read the decompressed image data by calling jpeg_read_scanlines() -one or more times. At each call, you pass in the maximum number of scanlines -to be read (ie, the height of your working buffer); jpeg_read_scanlines() -will return up to that many lines. The return value is the number of lines -actually read. The format of the returned data is discussed under "Data -formats", above. Don't forget that grayscale and color JPEGs will return -different data formats! - -Image data is returned in top-to-bottom scanline order. If you must write -out the image in bottom-to-top order, you can use the JPEG library's virtual -array mechanism to invert the data efficiently. Examples of this can be -found in the sample application djpeg. - -The library maintains a count of the number of scanlines returned so far -in the output_scanline field of the JPEG object. Usually you can just use -this variable as the loop counter, so that the loop test looks like -"while (cinfo.output_scanline < cinfo.output_height)". (Note that the test -should NOT be against image_height, unless you never use scaling. The -image_height field is the height of the original unscaled image.) -The return value always equals the change in the value of output_scanline. - -If you don't use a suspending data source, it is safe to assume that -jpeg_read_scanlines() reads at least one scanline per call, until the -bottom of the image has been reached. - -If you use a buffer larger than one scanline, it is NOT safe to assume that -jpeg_read_scanlines() fills it. (The current implementation returns only a -few scanlines per call, no matter how large a buffer you pass.) So you must -always provide a loop that calls jpeg_read_scanlines() repeatedly until the -whole image has been read. - - -7. jpeg_finish_decompress(...); - -After all the image data has been read, call jpeg_finish_decompress() to -complete the decompression cycle. This causes working memory associated -with the JPEG object to be released. - -Typical code: - - jpeg_finish_decompress(&cinfo); - -If using the stdio source manager, don't forget to close the source stdio -stream if necessary. - -It is an error to call jpeg_finish_decompress() before reading the correct -total number of scanlines. If you wish to abort decompression, call -jpeg_abort() as discussed below. - -After completing a decompression cycle, you may dispose of the JPEG object as -discussed next, or you may use it to decompress another image. In that case -return to step 2 or 3 as appropriate. If you do not change the source -manager, the next image will be read from the same source. - - -8. Release the JPEG decompression object. - -When you are done with a JPEG decompression object, destroy it by calling -jpeg_destroy_decompress() or jpeg_destroy(). The previous discussion of -destroying compression objects applies here too. - -Typical code: - - jpeg_destroy_decompress(&cinfo); - - -9. Aborting. - -You can abort a decompression cycle by calling jpeg_destroy_decompress() or -jpeg_destroy() if you don't need the JPEG object any more, or -jpeg_abort_decompress() or jpeg_abort() if you want to reuse the object. -The previous discussion of aborting compression cycles applies here too. - - -Mechanics of usage: include files, linking, etc ------------------------------------------------ - -Applications using the JPEG library should include the header file jpeglib.h -to obtain declarations of data types and routines. Before including -jpeglib.h, include system headers that define at least the typedefs FILE and -size_t. On ANSI-conforming systems, including is sufficient; on -older Unix systems, you may need to define size_t. - -If the application needs to refer to individual JPEG library error codes, also -include jerror.h to define those symbols. - -jpeglib.h indirectly includes the files jconfig.h and jmorecfg.h. If you are -installing the JPEG header files in a system directory, you will want to -install all four files: jpeglib.h, jerror.h, jconfig.h, jmorecfg.h. - -The most convenient way to include the JPEG code into your executable program -is to prepare a library file ("libjpeg.a", or a corresponding name on non-Unix -machines) and reference it at your link step. If you use only half of the -library (only compression or only decompression), only that much code will be -included from the library, unless your linker is hopelessly brain-damaged. -The supplied makefiles build libjpeg.a automatically (see install.doc). - -While you can build the JPEG library as a shared library if the whim strikes -you, we don't really recommend it. The trouble with shared libraries is that -at some point you'll probably try to substitute a new version of the library -without recompiling the calling applications. That generally doesn't work -because the parameter struct declarations usually change with each new -version. In other words, the library's API is *not* guaranteed binary -compatible across versions; we only try to ensure source-code compatibility. -(In hindsight, it might have been smarter to hide the parameter structs from -applications and introduce a ton of access functions instead. Too late now, -however.) - -On some systems your application may need to set up a signal handler to ensure -that temporary files are deleted if the program is interrupted. This is most -critical if you are on MS-DOS and use the jmemdos.c memory manager back end; -it will try to grab extended memory for temp files, and that space will NOT be -freed automatically. See cjpeg.c or djpeg.c for an example signal handler. - -It may be worth pointing out that the core JPEG library does not actually -require the stdio library: only the default source/destination managers and -error handler need it. You can use the library in a stdio-less environment -if you replace those modules and use jmemnobs.c (or another memory manager of -your own devising). More info about the minimum system library requirements -may be found in jinclude.h. - - -ADVANCED FEATURES -================= - -Compression parameter selection -------------------------------- - -This section describes all the optional parameters you can set for JPEG -compression, as well as the "helper" routines provided to assist in this -task. Proper setting of some parameters requires detailed understanding -of the JPEG standard; if you don't know what a parameter is for, it's best -not to mess with it! See REFERENCES in the README file for pointers to -more info about JPEG. - -It's a good idea to call jpeg_set_defaults() first, even if you plan to set -all the parameters; that way your code is more likely to work with future JPEG -libraries that have additional parameters. For the same reason, we recommend -you use a helper routine where one is provided, in preference to twiddling -cinfo fields directly. - -The helper routines are: - -jpeg_set_defaults (j_compress_ptr cinfo) - This routine sets all JPEG parameters to reasonable defaults, using - only the input image's color space (field in_color_space, which must - already be set in cinfo). Many applications will only need to use - this routine and perhaps jpeg_set_quality(). - -jpeg_set_colorspace (j_compress_ptr cinfo, J_COLOR_SPACE colorspace) - Sets the JPEG file's colorspace (field jpeg_color_space) as specified, - and sets other color-space-dependent parameters appropriately. See - "Special color spaces", below, before using this. A large number of - parameters, including all per-component parameters, are set by this - routine; if you want to twiddle individual parameters you should call - jpeg_set_colorspace() before rather than after. - -jpeg_default_colorspace (j_compress_ptr cinfo) - Selects an appropriate JPEG colorspace based on cinfo->in_color_space, - and calls jpeg_set_colorspace(). This is actually a subroutine of - jpeg_set_defaults(). It's broken out in case you want to change - just the colorspace-dependent JPEG parameters. - -jpeg_set_quality (j_compress_ptr cinfo, int quality, boolean force_baseline) - Constructs JPEG quantization tables appropriate for the indicated - quality setting. The quality value is expressed on the 0..100 scale - recommended by IJG (cjpeg's "-quality" switch uses this routine). - Note that the exact mapping from quality values to tables may change - in future IJG releases as more is learned about DCT quantization. - If the force_baseline parameter is TRUE, then the quantization table - entries are constrained to the range 1..255 for full JPEG baseline - compatibility. In the current implementation, this only makes a - difference for quality settings below 25, and it effectively prevents - very small/low quality files from being generated. The IJG decoder - is capable of reading the non-baseline files generated at low quality - settings when force_baseline is FALSE, but other decoders may not be. - -jpeg_set_linear_quality (j_compress_ptr cinfo, int scale_factor, - boolean force_baseline) - Same as jpeg_set_quality() except that the generated tables are the - sample tables given in the JPEC spec section K.1, multiplied by the - specified scale factor (which is expressed as a percentage; thus - scale_factor = 100 reproduces the spec's tables). Note that larger - scale factors give lower quality. This entry point is useful for - conforming to the Adobe PostScript DCT conventions, but we do not - recommend linear scaling as a user-visible quality scale otherwise. - force_baseline again constrains the computed table entries to 1..255. - -int jpeg_quality_scaling (int quality) - Converts a value on the IJG-recommended quality scale to a linear - scaling percentage. Note that this routine may change or go away - in future releases --- IJG may choose to adopt a scaling method that - can't be expressed as a simple scalar multiplier, in which case the - premise of this routine collapses. Caveat user. - -jpeg_add_quant_table (j_compress_ptr cinfo, int which_tbl, - const unsigned int *basic_table, - int scale_factor, boolean force_baseline) - Allows an arbitrary quantization table to be created. which_tbl - indicates which table slot to fill. basic_table points to an array - of 64 unsigned ints given in normal array order. These values are - multiplied by scale_factor/100 and then clamped to the range 1..65535 - (or to 1..255 if force_baseline is TRUE). - CAUTION: prior to library version 6a, jpeg_add_quant_table expected - the basic table to be given in JPEG zigzag order. If you need to - write code that works with either older or newer versions of this - routine, you must check the library version number. Something like - "#if JPEG_LIB_VERSION >= 61" is the right test. - -jpeg_simple_progression (j_compress_ptr cinfo) - Generates a default scan script for writing a progressive-JPEG file. - This is the recommended method of creating a progressive file, - unless you want to make a custom scan sequence. You must ensure that - the JPEG color space is set correctly before calling this routine. - - -Compression parameters (cinfo fields) include: - -J_DCT_METHOD dct_method - Selects the algorithm used for the DCT step. Choices are: - JDCT_ISLOW: slow but accurate integer algorithm - JDCT_IFAST: faster, less accurate integer method - JDCT_FLOAT: floating-point method - JDCT_DEFAULT: default method (normally JDCT_ISLOW) - JDCT_FASTEST: fastest method (normally JDCT_IFAST) - The FLOAT method is very slightly more accurate than the ISLOW method, - but may give different results on different machines due to varying - roundoff behavior. The integer methods should give the same results - on all machines. On machines with sufficiently fast FP hardware, the - floating-point method may also be the fastest. The IFAST method is - considerably less accurate than the other two; its use is not - recommended if high quality is a concern. JDCT_DEFAULT and - JDCT_FASTEST are macros configurable by each installation. - -J_COLOR_SPACE jpeg_color_space -int num_components - The JPEG color space and corresponding number of components; see - "Special color spaces", below, for more info. We recommend using - jpeg_set_color_space() if you want to change these. - -boolean optimize_coding - TRUE causes the compressor to compute optimal Huffman coding tables - for the image. This requires an extra pass over the data and - therefore costs a good deal of space and time. The default is - FALSE, which tells the compressor to use the supplied or default - Huffman tables. In most cases optimal tables save only a few percent - of file size compared to the default tables. Note that when this is - TRUE, you need not supply Huffman tables at all, and any you do - supply will be overwritten. - -unsigned int restart_interval -int restart_in_rows - To emit restart markers in the JPEG file, set one of these nonzero. - Set restart_interval to specify the exact interval in MCU blocks. - Set restart_in_rows to specify the interval in MCU rows. (If - restart_in_rows is not 0, then restart_interval is set after the - image width in MCUs is computed.) Defaults are zero (no restarts). - One restart marker per MCU row is often a good choice. - NOTE: the overhead of restart markers is higher in grayscale JPEG - files than in color files, and MUCH higher in progressive JPEGs. - If you use restarts, you may want to use larger intervals in those - cases. - -const jpeg_scan_info * scan_info -int num_scans - By default, scan_info is NULL; this causes the compressor to write a - single-scan sequential JPEG file. If not NULL, scan_info points to - an array of scan definition records of length num_scans. The - compressor will then write a JPEG file having one scan for each scan - definition record. This is used to generate noninterleaved or - progressive JPEG files. The library checks that the scan array - defines a valid JPEG scan sequence. (jpeg_simple_progression creates - a suitable scan definition array for progressive JPEG.) This is - discussed further under "Progressive JPEG support". - -int smoothing_factor - If non-zero, the input image is smoothed; the value should be 1 for - minimal smoothing to 100 for maximum smoothing. Consult jcsample.c - for details of the smoothing algorithm. The default is zero. - -boolean write_JFIF_header - If TRUE, a JFIF APP0 marker is emitted. jpeg_set_defaults() and - jpeg_set_colorspace() set this TRUE if a JFIF-legal JPEG color space - (ie, YCbCr or grayscale) is selected, otherwise FALSE. - -UINT8 JFIF_major_version -UINT8 JFIF_minor_version - The version number to be written into the JFIF marker. - jpeg_set_defaults() initializes the version to 1.01 (major=minor=1). - You should set it to 1.02 (major=1, minor=2) if you plan to write - any JFIF 1.02 extension markers. - -UINT8 density_unit -UINT16 X_density -UINT16 Y_density - The resolution information to be written into the JFIF marker; - not used otherwise. density_unit may be 0 for unknown, - 1 for dots/inch, or 2 for dots/cm. The default values are 0,1,1 - indicating square pixels of unknown size. - -boolean write_Adobe_marker - If TRUE, an Adobe APP14 marker is emitted. jpeg_set_defaults() and - jpeg_set_colorspace() set this TRUE if JPEG color space RGB, CMYK, - or YCCK is selected, otherwise FALSE. It is generally a bad idea - to set both write_JFIF_header and write_Adobe_marker. In fact, - you probably shouldn't change the default settings at all --- the - default behavior ensures that the JPEG file's color space can be - recognized by the decoder. - -JQUANT_TBL * quant_tbl_ptrs[NUM_QUANT_TBLS] - Pointers to coefficient quantization tables, one per table slot, - or NULL if no table is defined for a slot. Usually these should - be set via one of the above helper routines; jpeg_add_quant_table() - is general enough to define any quantization table. The other - routines will set up table slot 0 for luminance quality and table - slot 1 for chrominance. - -JHUFF_TBL * dc_huff_tbl_ptrs[NUM_HUFF_TBLS] -JHUFF_TBL * ac_huff_tbl_ptrs[NUM_HUFF_TBLS] - Pointers to Huffman coding tables, one per table slot, or NULL if - no table is defined for a slot. Slots 0 and 1 are filled with the - JPEG sample tables by jpeg_set_defaults(). If you need to allocate - more table structures, jpeg_alloc_huff_table() may be used. - Note that optimal Huffman tables can be computed for an image - by setting optimize_coding, as discussed above; there's seldom - any need to mess with providing your own Huffman tables. - -There are some additional cinfo fields which are not documented here -because you currently can't change them; for example, you can't set -arith_code TRUE because arithmetic coding is unsupported. - - -Per-component parameters are stored in the struct cinfo.comp_info[i] for -component number i. Note that components here refer to components of the -JPEG color space, *not* the source image color space. A suitably large -comp_info[] array is allocated by jpeg_set_defaults(); if you choose not -to use that routine, it's up to you to allocate the array. - -int component_id - The one-byte identifier code to be recorded in the JPEG file for - this component. For the standard color spaces, we recommend you - leave the default values alone. - -int h_samp_factor -int v_samp_factor - Horizontal and vertical sampling factors for the component; must - be 1..4 according to the JPEG standard. Note that larger sampling - factors indicate a higher-resolution component; many people find - this behavior quite unintuitive. The default values are 2,2 for - luminance components and 1,1 for chrominance components, except - for grayscale where 1,1 is used. - -int quant_tbl_no - Quantization table number for component. The default value is - 0 for luminance components and 1 for chrominance components. - -int dc_tbl_no -int ac_tbl_no - DC and AC entropy coding table numbers. The default values are - 0 for luminance components and 1 for chrominance components. - -int component_index - Must equal the component's index in comp_info[]. (Beginning in - release v6, the compressor library will fill this in automatically; - you don't have to.) - - -Decompression parameter selection ---------------------------------- - -Decompression parameter selection is somewhat simpler than compression -parameter selection, since all of the JPEG internal parameters are -recorded in the source file and need not be supplied by the application. -(Unless you are working with abbreviated files, in which case see -"Abbreviated datastreams", below.) Decompression parameters control -the postprocessing done on the image to deliver it in a format suitable -for the application's use. Many of the parameters control speed/quality -tradeoffs, in which faster decompression may be obtained at the price of -a poorer-quality image. The defaults select the highest quality (slowest) -processing. - -The following fields in the JPEG object are set by jpeg_read_header() and -may be useful to the application in choosing decompression parameters: - -JDIMENSION image_width Width and height of image -JDIMENSION image_height -int num_components Number of color components -J_COLOR_SPACE jpeg_color_space Colorspace of image -boolean saw_JFIF_marker TRUE if a JFIF APP0 marker was seen - UINT8 JFIF_major_version Version information from JFIF marker - UINT8 JFIF_minor_version - UINT8 density_unit Resolution data from JFIF marker - UINT16 X_density - UINT16 Y_density -boolean saw_Adobe_marker TRUE if an Adobe APP14 marker was seen - UINT8 Adobe_transform Color transform code from Adobe marker - -The JPEG color space, unfortunately, is something of a guess since the JPEG -standard proper does not provide a way to record it. In practice most files -adhere to the JFIF or Adobe conventions, and the decoder will recognize these -correctly. See "Special color spaces", below, for more info. - - -The decompression parameters that determine the basic properties of the -returned image are: - -J_COLOR_SPACE out_color_space - Output color space. jpeg_read_header() sets an appropriate default - based on jpeg_color_space; typically it will be RGB or grayscale. - The application can change this field to request output in a different - colorspace. For example, set it to JCS_GRAYSCALE to get grayscale - output from a color file. (This is useful for previewing: grayscale - output is faster than full color since the color components need not - be processed.) Note that not all possible color space transforms are - currently implemented; you may need to extend jdcolor.c if you want an - unusual conversion. - -unsigned int scale_num, scale_denom - Scale the image by the fraction scale_num/scale_denom. Default is - 1/1, or no scaling. Currently, the only supported scaling ratios - are 1/1, 1/2, 1/4, and 1/8. (The library design allows for arbitrary - scaling ratios but this is not likely to be implemented any time soon.) - Smaller scaling ratios permit significantly faster decoding since - fewer pixels need be processed and a simpler IDCT method can be used. - -boolean quantize_colors - If set TRUE, colormapped output will be delivered. Default is FALSE, - meaning that full-color output will be delivered. - -The next three parameters are relevant only if quantize_colors is TRUE. - -int desired_number_of_colors - Maximum number of colors to use in generating a library-supplied color - map (the actual number of colors is returned in a different field). - Default 256. Ignored when the application supplies its own color map. - -boolean two_pass_quantize - If TRUE, an extra pass over the image is made to select a custom color - map for the image. This usually looks a lot better than the one-size- - fits-all colormap that is used otherwise. Default is TRUE. Ignored - when the application supplies its own color map. - -J_DITHER_MODE dither_mode - Selects color dithering method. Supported values are: - JDITHER_NONE no dithering: fast, very low quality - JDITHER_ORDERED ordered dither: moderate speed and quality - JDITHER_FS Floyd-Steinberg dither: slow, high quality - Default is JDITHER_FS. (At present, ordered dither is implemented - only in the single-pass, standard-colormap case. If you ask for - ordered dither when two_pass_quantize is TRUE or when you supply - an external color map, you'll get F-S dithering.) - -When quantize_colors is TRUE, the target color map is described by the next -two fields. colormap is set to NULL by jpeg_read_header(). The application -can supply a color map by setting colormap non-NULL and setting -actual_number_of_colors to the map size. Otherwise, jpeg_start_decompress() -selects a suitable color map and sets these two fields itself. -[Implementation restriction: at present, an externally supplied colormap is -only accepted for 3-component output color spaces.] - -JSAMPARRAY colormap - The color map, represented as a 2-D pixel array of out_color_components - rows and actual_number_of_colors columns. Ignored if not quantizing. - CAUTION: if the JPEG library creates its own colormap, the storage - pointed to by this field is released by jpeg_finish_decompress(). - Copy the colormap somewhere else first, if you want to save it. - -int actual_number_of_colors - The number of colors in the color map. - -Additional decompression parameters that the application may set include: - -J_DCT_METHOD dct_method - Selects the algorithm used for the DCT step. Choices are the same - as described above for compression. - -boolean do_fancy_upsampling - If TRUE, do careful upsampling of chroma components. If FALSE, - a faster but sloppier method is used. Default is TRUE. The visual - impact of the sloppier method is often very small. - -boolean do_block_smoothing - If TRUE, interblock smoothing is applied in early stages of decoding - progressive JPEG files; if FALSE, not. Default is TRUE. Early - progression stages look "fuzzy" with smoothing, "blocky" without. - In any case, block smoothing ceases to be applied after the first few - AC coefficients are known to full accuracy, so it is relevant only - when using buffered-image mode for progressive images. - -boolean enable_1pass_quant -boolean enable_external_quant -boolean enable_2pass_quant - These are significant only in buffered-image mode, which is - described in its own section below. - - -The output image dimensions are given by the following fields. These are -computed from the source image dimensions and the decompression parameters -by jpeg_start_decompress(). You can also call jpeg_calc_output_dimensions() -to obtain the values that will result from the current parameter settings. -This can be useful if you are trying to pick a scaling ratio that will get -close to a desired target size. It's also important if you are using the -JPEG library's memory manager to allocate output buffer space, because you -are supposed to request such buffers *before* jpeg_start_decompress(). - -JDIMENSION output_width Actual dimensions of output image. -JDIMENSION output_height -int out_color_components Number of color components in out_color_space. -int output_components Number of color components returned. -int rec_outbuf_height Recommended height of scanline buffer. - -When quantizing colors, output_components is 1, indicating a single color map -index per pixel. Otherwise it equals out_color_components. The output arrays -are required to be output_width * output_components JSAMPLEs wide. - -rec_outbuf_height is the recommended minimum height (in scanlines) of the -buffer passed to jpeg_read_scanlines(). If the buffer is smaller, the -library will still work, but time will be wasted due to unnecessary data -copying. In high-quality modes, rec_outbuf_height is always 1, but some -faster, lower-quality modes set it to larger values (typically 2 to 4). -If you are going to ask for a high-speed processing mode, you may as well -go to the trouble of honoring rec_outbuf_height so as to avoid data copying. -(An output buffer larger than rec_outbuf_height lines is OK, but won't -provide any material speed improvement over that height.) - - -Special color spaces --------------------- - -The JPEG standard itself is "color blind" and doesn't specify any particular -color space. It is customary to convert color data to a luminance/chrominance -color space before compressing, since this permits greater compression. The -existing de-facto JPEG file format standards specify YCbCr or grayscale data -(JFIF), or grayscale, RGB, YCbCr, CMYK, or YCCK (Adobe). For special -applications such as multispectral images, other color spaces can be used, -but it must be understood that such files will be unportable. - -The JPEG library can handle the most common colorspace conversions (namely -RGB <=> YCbCr and CMYK <=> YCCK). It can also deal with data of an unknown -color space, passing it through without conversion. If you deal extensively -with an unusual color space, you can easily extend the library to understand -additional color spaces and perform appropriate conversions. - -For compression, the source data's color space is specified by field -in_color_space. This is transformed to the JPEG file's color space given -by jpeg_color_space. jpeg_set_defaults() chooses a reasonable JPEG color -space depending on in_color_space, but you can override this by calling -jpeg_set_colorspace(). Of course you must select a supported transformation. -jccolor.c currently supports the following transformations: - RGB => YCbCr - RGB => GRAYSCALE - YCbCr => GRAYSCALE - CMYK => YCCK -plus the null transforms: GRAYSCALE => GRAYSCALE, RGB => RGB, -YCbCr => YCbCr, CMYK => CMYK, YCCK => YCCK, and UNKNOWN => UNKNOWN. - -The de-facto file format standards (JFIF and Adobe) specify APPn markers that -indicate the color space of the JPEG file. It is important to ensure that -these are written correctly, or omitted if the JPEG file's color space is not -one of the ones supported by the de-facto standards. jpeg_set_colorspace() -will set the compression parameters to include or omit the APPn markers -properly, so long as it is told the truth about the JPEG color space. -For example, if you are writing some random 3-component color space without -conversion, don't try to fake out the library by setting in_color_space and -jpeg_color_space to JCS_YCbCr; use JCS_UNKNOWN. You may want to write an -APPn marker of your own devising to identify the colorspace --- see "Special -markers", below. - -When told that the color space is UNKNOWN, the library will default to using -luminance-quality compression parameters for all color components. You may -well want to change these parameters. See the source code for -jpeg_set_colorspace(), in jcparam.c, for details. - -For decompression, the JPEG file's color space is given in jpeg_color_space, -and this is transformed to the output color space out_color_space. -jpeg_read_header's setting of jpeg_color_space can be relied on if the file -conforms to JFIF or Adobe conventions, but otherwise it is no better than a -guess. If you know the JPEG file's color space for certain, you can override -jpeg_read_header's guess by setting jpeg_color_space. jpeg_read_header also -selects a default output color space based on (its guess of) jpeg_color_space; -set out_color_space to override this. Again, you must select a supported -transformation. jdcolor.c currently supports - YCbCr => GRAYSCALE - YCbCr => RGB - GRAYSCALE => RGB - YCCK => CMYK -as well as the null transforms. (Since GRAYSCALE=>RGB is provided, an -application can force grayscale JPEGs to look like color JPEGs if it only -wants to handle one case.) - -The two-pass color quantizer, jquant2.c, is specialized to handle RGB data -(it weights distances appropriately for RGB colors). You'll need to modify -the code if you want to use it for non-RGB output color spaces. Note that -jquant2.c is used to map to an application-supplied colormap as well as for -the normal two-pass colormap selection process. - -CAUTION: it appears that Adobe Photoshop writes inverted data in CMYK JPEG -files: 0 represents 100% ink coverage, rather than 0% ink as you'd expect. -This is arguably a bug in Photoshop, but if you need to work with Photoshop -CMYK files, you will have to deal with it in your application. We cannot -"fix" this in the library by inverting the data during the CMYK<=>YCCK -transform, because that would break other applications, notably Ghostscript. -Photoshop versions prior to 3.0 write EPS files containing JPEG-encoded CMYK -data in the same inverted-YCCK representation used in bare JPEG files, but -the surrounding PostScript code performs an inversion using the PS image -operator. I am told that Photoshop 3.0 will write uninverted YCCK in -EPS/JPEG files, and will omit the PS-level inversion. (But the data -polarity used in bare JPEG files will not change in 3.0.) In either case, -the JPEG library must not invert the data itself, or else Ghostscript would -read these EPS files incorrectly. - - -Error handling --------------- - -When the default error handler is used, any error detected inside the JPEG -routines will cause a message to be printed on stderr, followed by exit(). -You can supply your own error handling routines to override this behavior -and to control the treatment of nonfatal warnings and trace/debug messages. -The file example.c illustrates the most common case, which is to have the -application regain control after an error rather than exiting. - -The JPEG library never writes any message directly; it always goes through -the error handling routines. Three classes of messages are recognized: - * Fatal errors: the library cannot continue. - * Warnings: the library can continue, but the data is corrupt, and a - damaged output image is likely to result. - * Trace/informational messages. These come with a trace level indicating - the importance of the message; you can control the verbosity of the - program by adjusting the maximum trace level that will be displayed. - -You may, if you wish, simply replace the entire JPEG error handling module -(jerror.c) with your own code. However, you can avoid code duplication by -only replacing some of the routines depending on the behavior you need. -This is accomplished by calling jpeg_std_error() as usual, but then overriding -some of the method pointers in the jpeg_error_mgr struct, as illustrated by -example.c. - -All of the error handling routines will receive a pointer to the JPEG object -(a j_common_ptr which points to either a jpeg_compress_struct or a -jpeg_decompress_struct; if you need to tell which, test the is_decompressor -field). This struct includes a pointer to the error manager struct in its -"err" field. Frequently, custom error handler routines will need to access -additional data which is not known to the JPEG library or the standard error -handler. The most convenient way to do this is to embed either the JPEG -object or the jpeg_error_mgr struct in a larger structure that contains -additional fields; then casting the passed pointer provides access to the -additional fields. Again, see example.c for one way to do it. (Beginning -with IJG version 6b, there is also a void pointer "client_data" in each -JPEG object, which the application can also use to find related data. -The library does not touch client_data at all.) - -The individual methods that you might wish to override are: - -error_exit (j_common_ptr cinfo) - Receives control for a fatal error. Information sufficient to - generate the error message has been stored in cinfo->err; call - output_message to display it. Control must NOT return to the caller; - generally this routine will exit() or longjmp() somewhere. - Typically you would override this routine to get rid of the exit() - default behavior. Note that if you continue processing, you should - clean up the JPEG object with jpeg_abort() or jpeg_destroy(). - -output_message (j_common_ptr cinfo) - Actual output of any JPEG message. Override this to send messages - somewhere other than stderr. Note that this method does not know - how to generate a message, only where to send it. - -format_message (j_common_ptr cinfo, char * buffer) - Constructs a readable error message string based on the error info - stored in cinfo->err. This method is called by output_message. Few - applications should need to override this method. One possible - reason for doing so is to implement dynamic switching of error message - language. - -emit_message (j_common_ptr cinfo, int msg_level) - Decide whether or not to emit a warning or trace message; if so, - calls output_message. The main reason for overriding this method - would be to abort on warnings. msg_level is -1 for warnings, - 0 and up for trace messages. - -Only error_exit() and emit_message() are called from the rest of the JPEG -library; the other two are internal to the error handler. - -The actual message texts are stored in an array of strings which is pointed to -by the field err->jpeg_message_table. The messages are numbered from 0 to -err->last_jpeg_message, and it is these code numbers that are used in the -JPEG library code. You could replace the message texts (for instance, with -messages in French or German) by changing the message table pointer. See -jerror.h for the default texts. CAUTION: this table will almost certainly -change or grow from one library version to the next. - -It may be useful for an application to add its own message texts that are -handled by the same mechanism. The error handler supports a second "add-on" -message table for this purpose. To define an addon table, set the pointer -err->addon_message_table and the message numbers err->first_addon_message and -err->last_addon_message. If you number the addon messages beginning at 1000 -or so, you won't have to worry about conflicts with the library's built-in -messages. See the sample applications cjpeg/djpeg for an example of using -addon messages (the addon messages are defined in cderror.h). - -Actual invocation of the error handler is done via macros defined in jerror.h: - ERREXITn(...) for fatal errors - WARNMSn(...) for corrupt-data warnings - TRACEMSn(...) for trace and informational messages. -These macros store the message code and any additional parameters into the -error handler struct, then invoke the error_exit() or emit_message() method. -The variants of each macro are for varying numbers of additional parameters. -The additional parameters are inserted into the generated message using -standard printf() format codes. - -See jerror.h and jerror.c for further details. - - -Compressed data handling (source and destination managers) ----------------------------------------------------------- - -The JPEG compression library sends its compressed data to a "destination -manager" module. The default destination manager just writes the data to a -stdio stream, but you can provide your own manager to do something else. -Similarly, the decompression library calls a "source manager" to obtain the -compressed data; you can provide your own source manager if you want the data -to come from somewhere other than a stdio stream. - -In both cases, compressed data is processed a bufferload at a time: the -destination or source manager provides a work buffer, and the library invokes -the manager only when the buffer is filled or emptied. (You could define a -one-character buffer to force the manager to be invoked for each byte, but -that would be rather inefficient.) The buffer's size and location are -controlled by the manager, not by the library. For example, if you desired to -decompress a JPEG datastream that was all in memory, you could just make the -buffer pointer and length point to the original data in memory. Then the -buffer-reload procedure would be invoked only if the decompressor ran off the -end of the datastream, which would indicate an erroneous datastream. - -The work buffer is defined as an array of datatype JOCTET, which is generally -"char" or "unsigned char". On a machine where char is not exactly 8 bits -wide, you must define JOCTET as a wider data type and then modify the data -source and destination modules to transcribe the work arrays into 8-bit units -on external storage. - -A data destination manager struct contains a pointer and count defining the -next byte to write in the work buffer and the remaining free space: - - JOCTET * next_output_byte; /* => next byte to write in buffer */ - size_t free_in_buffer; /* # of byte spaces remaining in buffer */ - -The library increments the pointer and decrements the count until the buffer -is filled. The manager's empty_output_buffer method must reset the pointer -and count. The manager is expected to remember the buffer's starting address -and total size in private fields not visible to the library. - -A data destination manager provides three methods: - -init_destination (j_compress_ptr cinfo) - Initialize destination. This is called by jpeg_start_compress() - before any data is actually written. It must initialize - next_output_byte and free_in_buffer. free_in_buffer must be - initialized to a positive value. - -empty_output_buffer (j_compress_ptr cinfo) - This is called whenever the buffer has filled (free_in_buffer - reaches zero). In typical applications, it should write out the - *entire* buffer (use the saved start address and buffer length; - ignore the current state of next_output_byte and free_in_buffer). - Then reset the pointer & count to the start of the buffer, and - return TRUE indicating that the buffer has been dumped. - free_in_buffer must be set to a positive value when TRUE is - returned. A FALSE return should only be used when I/O suspension is - desired (this operating mode is discussed in the next section). - -term_destination (j_compress_ptr cinfo) - Terminate destination --- called by jpeg_finish_compress() after all - data has been written. In most applications, this must flush any - data remaining in the buffer. Use either next_output_byte or - free_in_buffer to determine how much data is in the buffer. - -term_destination() is NOT called by jpeg_abort() or jpeg_destroy(). If you -want the destination manager to be cleaned up during an abort, you must do it -yourself. - -You will also need code to create a jpeg_destination_mgr struct, fill in its -method pointers, and insert a pointer to the struct into the "dest" field of -the JPEG compression object. This can be done in-line in your setup code if -you like, but it's probably cleaner to provide a separate routine similar to -the jpeg_stdio_dest() routine of the supplied destination manager. - -Decompression source managers follow a parallel design, but with some -additional frammishes. The source manager struct contains a pointer and count -defining the next byte to read from the work buffer and the number of bytes -remaining: - - const JOCTET * next_input_byte; /* => next byte to read from buffer */ - size_t bytes_in_buffer; /* # of bytes remaining in buffer */ - -The library increments the pointer and decrements the count until the buffer -is emptied. The manager's fill_input_buffer method must reset the pointer and -count. In most applications, the manager must remember the buffer's starting -address and total size in private fields not visible to the library. - -A data source manager provides five methods: - -init_source (j_decompress_ptr cinfo) - Initialize source. This is called by jpeg_read_header() before any - data is actually read. Unlike init_destination(), it may leave - bytes_in_buffer set to 0 (in which case a fill_input_buffer() call - will occur immediately). - -fill_input_buffer (j_decompress_ptr cinfo) - This is called whenever bytes_in_buffer has reached zero and more - data is wanted. In typical applications, it should read fresh data - into the buffer (ignoring the current state of next_input_byte and - bytes_in_buffer), reset the pointer & count to the start of the - buffer, and return TRUE indicating that the buffer has been reloaded. - It is not necessary to fill the buffer entirely, only to obtain at - least one more byte. bytes_in_buffer MUST be set to a positive value - if TRUE is returned. A FALSE return should only be used when I/O - suspension is desired (this mode is discussed in the next section). - -skip_input_data (j_decompress_ptr cinfo, long num_bytes) - Skip num_bytes worth of data. The buffer pointer and count should - be advanced over num_bytes input bytes, refilling the buffer as - needed. This is used to skip over a potentially large amount of - uninteresting data (such as an APPn marker). In some applications - it may be possible to optimize away the reading of the skipped data, - but it's not clear that being smart is worth much trouble; large - skips are uncommon. bytes_in_buffer may be zero on return. - A zero or negative skip count should be treated as a no-op. - -resync_to_restart (j_decompress_ptr cinfo, int desired) - This routine is called only when the decompressor has failed to find - a restart (RSTn) marker where one is expected. Its mission is to - find a suitable point for resuming decompression. For most - applications, we recommend that you just use the default resync - procedure, jpeg_resync_to_restart(). However, if you are able to back - up in the input data stream, or if you have a-priori knowledge about - the likely location of restart markers, you may be able to do better. - Read the read_restart_marker() and jpeg_resync_to_restart() routines - in jdmarker.c if you think you'd like to implement your own resync - procedure. - -term_source (j_decompress_ptr cinfo) - Terminate source --- called by jpeg_finish_decompress() after all - data has been read. Often a no-op. - -For both fill_input_buffer() and skip_input_data(), there is no such thing -as an EOF return. If the end of the file has been reached, the routine has -a choice of exiting via ERREXIT() or inserting fake data into the buffer. -In most cases, generating a warning message and inserting a fake EOI marker -is the best course of action --- this will allow the decompressor to output -however much of the image is there. In pathological cases, the decompressor -may swallow the EOI and again demand data ... just keep feeding it fake EOIs. -jdatasrc.c illustrates the recommended error recovery behavior. - -term_source() is NOT called by jpeg_abort() or jpeg_destroy(). If you want -the source manager to be cleaned up during an abort, you must do it yourself. - -You will also need code to create a jpeg_source_mgr struct, fill in its method -pointers, and insert a pointer to the struct into the "src" field of the JPEG -decompression object. This can be done in-line in your setup code if you -like, but it's probably cleaner to provide a separate routine similar to the -jpeg_stdio_src() routine of the supplied source manager. - -For more information, consult the stdio source and destination managers -in jdatasrc.c and jdatadst.c. - - -I/O suspension --------------- - -Some applications need to use the JPEG library as an incremental memory-to- -memory filter: when the compressed data buffer is filled or emptied, they want -control to return to the outer loop, rather than expecting that the buffer can -be emptied or reloaded within the data source/destination manager subroutine. -The library supports this need by providing an "I/O suspension" mode, which we -describe in this section. - -The I/O suspension mode is not a panacea: nothing is guaranteed about the -maximum amount of time spent in any one call to the library, so it will not -eliminate response-time problems in single-threaded applications. If you -need guaranteed response time, we suggest you "bite the bullet" and implement -a real multi-tasking capability. - -To use I/O suspension, cooperation is needed between the calling application -and the data source or destination manager; you will always need a custom -source/destination manager. (Please read the previous section if you haven't -already.) The basic idea is that the empty_output_buffer() or -fill_input_buffer() routine is a no-op, merely returning FALSE to indicate -that it has done nothing. Upon seeing this, the JPEG library suspends -operation and returns to its caller. The surrounding application is -responsible for emptying or refilling the work buffer before calling the -JPEG library again. - -Compression suspension: - -For compression suspension, use an empty_output_buffer() routine that returns -FALSE; typically it will not do anything else. This will cause the -compressor to return to the caller of jpeg_write_scanlines(), with the return -value indicating that not all the supplied scanlines have been accepted. -The application must make more room in the output buffer, adjust the output -buffer pointer/count appropriately, and then call jpeg_write_scanlines() -again, pointing to the first unconsumed scanline. - -When forced to suspend, the compressor will backtrack to a convenient stopping -point (usually the start of the current MCU); it will regenerate some output -data when restarted. Therefore, although empty_output_buffer() is only -called when the buffer is filled, you should NOT write out the entire buffer -after a suspension. Write only the data up to the current position of -next_output_byte/free_in_buffer. The data beyond that point will be -regenerated after resumption. - -Because of the backtracking behavior, a good-size output buffer is essential -for efficiency; you don't want the compressor to suspend often. (In fact, an -overly small buffer could lead to infinite looping, if a single MCU required -more data than would fit in the buffer.) We recommend a buffer of at least -several Kbytes. You may want to insert explicit code to ensure that you don't -call jpeg_write_scanlines() unless there is a reasonable amount of space in -the output buffer; in other words, flush the buffer before trying to compress -more data. - -The compressor does not allow suspension while it is trying to write JPEG -markers at the beginning and end of the file. This means that: - * At the beginning of a compression operation, there must be enough free - space in the output buffer to hold the header markers (typically 600 or - so bytes). The recommended buffer size is bigger than this anyway, so - this is not a problem as long as you start with an empty buffer. However, - this restriction might catch you if you insert large special markers, such - as a JFIF thumbnail image, without flushing the buffer afterwards. - * When you call jpeg_finish_compress(), there must be enough space in the - output buffer to emit any buffered data and the final EOI marker. In the - current implementation, half a dozen bytes should suffice for this, but - for safety's sake we recommend ensuring that at least 100 bytes are free - before calling jpeg_finish_compress(). - -A more significant restriction is that jpeg_finish_compress() cannot suspend. -This means you cannot use suspension with multi-pass operating modes, namely -Huffman code optimization and multiple-scan output. Those modes write the -whole file during jpeg_finish_compress(), which will certainly result in -buffer overrun. (Note that this restriction applies only to compression, -not decompression. The decompressor supports input suspension in all of its -operating modes.) - -Decompression suspension: - -For decompression suspension, use a fill_input_buffer() routine that simply -returns FALSE (except perhaps during error recovery, as discussed below). -This will cause the decompressor to return to its caller with an indication -that suspension has occurred. This can happen at four places: - * jpeg_read_header(): will return JPEG_SUSPENDED. - * jpeg_start_decompress(): will return FALSE, rather than its usual TRUE. - * jpeg_read_scanlines(): will return the number of scanlines already - completed (possibly 0). - * jpeg_finish_decompress(): will return FALSE, rather than its usual TRUE. -The surrounding application must recognize these cases, load more data into -the input buffer, and repeat the call. In the case of jpeg_read_scanlines(), -increment the passed pointers past any scanlines successfully read. - -Just as with compression, the decompressor will typically backtrack to a -convenient restart point before suspending. When fill_input_buffer() is -called, next_input_byte/bytes_in_buffer point to the current restart point, -which is where the decompressor will backtrack to if FALSE is returned. -The data beyond that position must NOT be discarded if you suspend; it needs -to be re-read upon resumption. In most implementations, you'll need to shift -this data down to the start of your work buffer and then load more data after -it. Again, this behavior means that a several-Kbyte work buffer is essential -for decent performance; furthermore, you should load a reasonable amount of -new data before resuming decompression. (If you loaded, say, only one new -byte each time around, you could waste a LOT of cycles.) - -The skip_input_data() source manager routine requires special care in a -suspension scenario. This routine is NOT granted the ability to suspend the -decompressor; it can decrement bytes_in_buffer to zero, but no more. If the -requested skip distance exceeds the amount of data currently in the input -buffer, then skip_input_data() must set bytes_in_buffer to zero and record the -additional skip distance somewhere else. The decompressor will immediately -call fill_input_buffer(), which should return FALSE, which will cause a -suspension return. The surrounding application must then arrange to discard -the recorded number of bytes before it resumes loading the input buffer. -(Yes, this design is rather baroque, but it avoids complexity in the far more -common case where a non-suspending source manager is used.) - -If the input data has been exhausted, we recommend that you emit a warning -and insert dummy EOI markers just as a non-suspending data source manager -would do. This can be handled either in the surrounding application logic or -within fill_input_buffer(); the latter is probably more efficient. If -fill_input_buffer() knows that no more data is available, it can set the -pointer/count to point to a dummy EOI marker and then return TRUE just as -though it had read more data in a non-suspending situation. - -The decompressor does not attempt to suspend within standard JPEG markers; -instead it will backtrack to the start of the marker and reprocess the whole -marker next time. Hence the input buffer must be large enough to hold the -longest standard marker in the file. Standard JPEG markers should normally -not exceed a few hundred bytes each (DHT tables are typically the longest). -We recommend at least a 2K buffer for performance reasons, which is much -larger than any correct marker is likely to be. For robustness against -damaged marker length counts, you may wish to insert a test in your -application for the case that the input buffer is completely full and yet -the decoder has suspended without consuming any data --- otherwise, if this -situation did occur, it would lead to an endless loop. (The library can't -provide this test since it has no idea whether "the buffer is full", or -even whether there is a fixed-size input buffer.) - -The input buffer would need to be 64K to allow for arbitrary COM or APPn -markers, but these are handled specially: they are either saved into allocated -memory, or skipped over by calling skip_input_data(). In the former case, -suspension is handled correctly, and in the latter case, the problem of -buffer overrun is placed on skip_input_data's shoulders, as explained above. -Note that if you provide your own marker handling routine for large markers, -you should consider how to deal with buffer overflow. - -Multiple-buffer management: - -In some applications it is desirable to store the compressed data in a linked -list of buffer areas, so as to avoid data copying. This can be handled by -having empty_output_buffer() or fill_input_buffer() set the pointer and count -to reference the next available buffer; FALSE is returned only if no more -buffers are available. Although seemingly straightforward, there is a -pitfall in this approach: the backtrack that occurs when FALSE is returned -could back up into an earlier buffer. For example, when fill_input_buffer() -is called, the current pointer & count indicate the backtrack restart point. -Since fill_input_buffer() will set the pointer and count to refer to a new -buffer, the restart position must be saved somewhere else. Suppose a second -call to fill_input_buffer() occurs in the same library call, and no -additional input data is available, so fill_input_buffer must return FALSE. -If the JPEG library has not moved the pointer/count forward in the current -buffer, then *the correct restart point is the saved position in the prior -buffer*. Prior buffers may be discarded only after the library establishes -a restart point within a later buffer. Similar remarks apply for output into -a chain of buffers. - -The library will never attempt to backtrack over a skip_input_data() call, -so any skipped data can be permanently discarded. You still have to deal -with the case of skipping not-yet-received data, however. - -It's much simpler to use only a single buffer; when fill_input_buffer() is -called, move any unconsumed data (beyond the current pointer/count) down to -the beginning of this buffer and then load new data into the remaining buffer -space. This approach requires a little more data copying but is far easier -to get right. - - -Progressive JPEG support ------------------------- - -Progressive JPEG rearranges the stored data into a series of scans of -increasing quality. In situations where a JPEG file is transmitted across a -slow communications link, a decoder can generate a low-quality image very -quickly from the first scan, then gradually improve the displayed quality as -more scans are received. The final image after all scans are complete is -identical to that of a regular (sequential) JPEG file of the same quality -setting. Progressive JPEG files are often slightly smaller than equivalent -sequential JPEG files, but the possibility of incremental display is the main -reason for using progressive JPEG. - -The IJG encoder library generates progressive JPEG files when given a -suitable "scan script" defining how to divide the data into scans. -Creation of progressive JPEG files is otherwise transparent to the encoder. -Progressive JPEG files can also be read transparently by the decoder library. -If the decoding application simply uses the library as defined above, it -will receive a final decoded image without any indication that the file was -progressive. Of course, this approach does not allow incremental display. -To perform incremental display, an application needs to use the decoder -library's "buffered-image" mode, in which it receives a decoded image -multiple times. - -Each displayed scan requires about as much work to decode as a full JPEG -image of the same size, so the decoder must be fairly fast in relation to the -data transmission rate in order to make incremental display useful. However, -it is possible to skip displaying the image and simply add the incoming bits -to the decoder's coefficient buffer. This is fast because only Huffman -decoding need be done, not IDCT, upsampling, colorspace conversion, etc. -The IJG decoder library allows the application to switch dynamically between -displaying the image and simply absorbing the incoming bits. A properly -coded application can automatically adapt the number of display passes to -suit the time available as the image is received. Also, a final -higher-quality display cycle can be performed from the buffered data after -the end of the file is reached. - -Progressive compression: - -To create a progressive JPEG file (or a multiple-scan sequential JPEG file), -set the scan_info cinfo field to point to an array of scan descriptors, and -perform compression as usual. Instead of constructing your own scan list, -you can call the jpeg_simple_progression() helper routine to create a -recommended progression sequence; this method should be used by all -applications that don't want to get involved in the nitty-gritty of -progressive scan sequence design. (If you want to provide user control of -scan sequences, you may wish to borrow the scan script reading code found -in rdswitch.c, so that you can read scan script files just like cjpeg's.) -When scan_info is not NULL, the compression library will store DCT'd data -into a buffer array as jpeg_write_scanlines() is called, and will emit all -the requested scans during jpeg_finish_compress(). This implies that -multiple-scan output cannot be created with a suspending data destination -manager, since jpeg_finish_compress() does not support suspension. We -should also note that the compressor currently forces Huffman optimization -mode when creating a progressive JPEG file, because the default Huffman -tables are unsuitable for progressive files. - -Progressive decompression: - -When buffered-image mode is not used, the decoder library will read all of -a multi-scan file during jpeg_start_decompress(), so that it can provide a -final decoded image. (Here "multi-scan" means either progressive or -multi-scan sequential.) This makes multi-scan files transparent to the -decoding application. However, existing applications that used suspending -input with version 5 of the IJG library will need to be modified to check -for a suspension return from jpeg_start_decompress(). - -To perform incremental display, an application must use the library's -buffered-image mode. This is described in the next section. - - -Buffered-image mode -------------------- - -In buffered-image mode, the library stores the partially decoded image in a -coefficient buffer, from which it can be read out as many times as desired. -This mode is typically used for incremental display of progressive JPEG files, -but it can be used with any JPEG file. Each scan of a progressive JPEG file -adds more data (more detail) to the buffered image. The application can -display in lockstep with the source file (one display pass per input scan), -or it can allow input processing to outrun display processing. By making -input and display processing run independently, it is possible for the -application to adapt progressive display to a wide range of data transmission -rates. - -The basic control flow for buffered-image decoding is - - jpeg_create_decompress() - set data source - jpeg_read_header() - set overall decompression parameters - cinfo.buffered_image = TRUE; /* select buffered-image mode */ - jpeg_start_decompress() - for (each output pass) { - adjust output decompression parameters if required - jpeg_start_output() /* start a new output pass */ - for (all scanlines in image) { - jpeg_read_scanlines() - display scanlines - } - jpeg_finish_output() /* terminate output pass */ - } - jpeg_finish_decompress() - jpeg_destroy_decompress() - -This differs from ordinary unbuffered decoding in that there is an additional -level of looping. The application can choose how many output passes to make -and how to display each pass. - -The simplest approach to displaying progressive images is to do one display -pass for each scan appearing in the input file. In this case the outer loop -condition is typically - while (! jpeg_input_complete(&cinfo)) -and the start-output call should read - jpeg_start_output(&cinfo, cinfo.input_scan_number); -The second parameter to jpeg_start_output() indicates which scan of the input -file is to be displayed; the scans are numbered starting at 1 for this -purpose. (You can use a loop counter starting at 1 if you like, but using -the library's input scan counter is easier.) The library automatically reads -data as necessary to complete each requested scan, and jpeg_finish_output() -advances to the next scan or end-of-image marker (hence input_scan_number -will be incremented by the time control arrives back at jpeg_start_output()). -With this technique, data is read from the input file only as needed, and -input and output processing run in lockstep. - -After reading the final scan and reaching the end of the input file, the -buffered image remains available; it can be read additional times by -repeating the jpeg_start_output()/jpeg_read_scanlines()/jpeg_finish_output() -sequence. For example, a useful technique is to use fast one-pass color -quantization for display passes made while the image is arriving, followed by -a final display pass using two-pass quantization for highest quality. This -is done by changing the library parameters before the final output pass. -Changing parameters between passes is discussed in detail below. - -In general the last scan of a progressive file cannot be recognized as such -until after it is read, so a post-input display pass is the best approach if -you want special processing in the final pass. - -When done with the image, be sure to call jpeg_finish_decompress() to release -the buffered image (or just use jpeg_destroy_decompress()). - -If input data arrives faster than it can be displayed, the application can -cause the library to decode input data in advance of what's needed to produce -output. This is done by calling the routine jpeg_consume_input(). -The return value is one of the following: - JPEG_REACHED_SOS: reached an SOS marker (the start of a new scan) - JPEG_REACHED_EOI: reached the EOI marker (end of image) - JPEG_ROW_COMPLETED: completed reading one MCU row of compressed data - JPEG_SCAN_COMPLETED: completed reading last MCU row of current scan - JPEG_SUSPENDED: suspended before completing any of the above -(JPEG_SUSPENDED can occur only if a suspending data source is used.) This -routine can be called at any time after initializing the JPEG object. It -reads some additional data and returns when one of the indicated significant -events occurs. (If called after the EOI marker is reached, it will -immediately return JPEG_REACHED_EOI without attempting to read more data.) - -The library's output processing will automatically call jpeg_consume_input() -whenever the output processing overtakes the input; thus, simple lockstep -display requires no direct calls to jpeg_consume_input(). But by adding -calls to jpeg_consume_input(), you can absorb data in advance of what is -being displayed. This has two benefits: - * You can limit buildup of unprocessed data in your input buffer. - * You can eliminate extra display passes by paying attention to the - state of the library's input processing. - -The first of these benefits only requires interspersing calls to -jpeg_consume_input() with your display operations and any other processing -you may be doing. To avoid wasting cycles due to backtracking, it's best to -call jpeg_consume_input() only after a hundred or so new bytes have arrived. -This is discussed further under "I/O suspension", above. (Note: the JPEG -library currently is not thread-safe. You must not call jpeg_consume_input() -from one thread of control if a different library routine is working on the -same JPEG object in another thread.) - -When input arrives fast enough that more than one new scan is available -before you start a new output pass, you may as well skip the output pass -corresponding to the completed scan. This occurs for free if you pass -cinfo.input_scan_number as the target scan number to jpeg_start_output(). -The input_scan_number field is simply the index of the scan currently being -consumed by the input processor. You can ensure that this is up-to-date by -emptying the input buffer just before calling jpeg_start_output(): call -jpeg_consume_input() repeatedly until it returns JPEG_SUSPENDED or -JPEG_REACHED_EOI. - -The target scan number passed to jpeg_start_output() is saved in the -cinfo.output_scan_number field. The library's output processing calls -jpeg_consume_input() whenever the current input scan number and row within -that scan is less than or equal to the current output scan number and row. -Thus, input processing can "get ahead" of the output processing but is not -allowed to "fall behind". You can achieve several different effects by -manipulating this interlock rule. For example, if you pass a target scan -number greater than the current input scan number, the output processor will -wait until that scan starts to arrive before producing any output. (To avoid -an infinite loop, the target scan number is automatically reset to the last -scan number when the end of image is reached. Thus, if you specify a large -target scan number, the library will just absorb the entire input file and -then perform an output pass. This is effectively the same as what -jpeg_start_decompress() does when you don't select buffered-image mode.) -When you pass a target scan number equal to the current input scan number, -the image is displayed no faster than the current input scan arrives. The -final possibility is to pass a target scan number less than the current input -scan number; this disables the input/output interlock and causes the output -processor to simply display whatever it finds in the image buffer, without -waiting for input. (However, the library will not accept a target scan -number less than one, so you can't avoid waiting for the first scan.) - -When data is arriving faster than the output display processing can advance -through the image, jpeg_consume_input() will store data into the buffered -image beyond the point at which the output processing is reading data out -again. If the input arrives fast enough, it may "wrap around" the buffer to -the point where the input is more than one whole scan ahead of the output. -If the output processing simply proceeds through its display pass without -paying attention to the input, the effect seen on-screen is that the lower -part of the image is one or more scans better in quality than the upper part. -Then, when the next output scan is started, you have a choice of what target -scan number to use. The recommended choice is to use the current input scan -number at that time, which implies that you've skipped the output scans -corresponding to the input scans that were completed while you processed the -previous output scan. In this way, the decoder automatically adapts its -speed to the arriving data, by skipping output scans as necessary to keep up -with the arriving data. - -When using this strategy, you'll want to be sure that you perform a final -output pass after receiving all the data; otherwise your last display may not -be full quality across the whole screen. So the right outer loop logic is -something like this: - do { - absorb any waiting input by calling jpeg_consume_input() - final_pass = jpeg_input_complete(&cinfo); - adjust output decompression parameters if required - jpeg_start_output(&cinfo, cinfo.input_scan_number); - ... - jpeg_finish_output() - } while (! final_pass); -rather than quitting as soon as jpeg_input_complete() returns TRUE. This -arrangement makes it simple to use higher-quality decoding parameters -for the final pass. But if you don't want to use special parameters for -the final pass, the right loop logic is like this: - for (;;) { - absorb any waiting input by calling jpeg_consume_input() - jpeg_start_output(&cinfo, cinfo.input_scan_number); - ... - jpeg_finish_output() - if (jpeg_input_complete(&cinfo) && - cinfo.input_scan_number == cinfo.output_scan_number) - break; - } -In this case you don't need to know in advance whether an output pass is to -be the last one, so it's not necessary to have reached EOF before starting -the final output pass; rather, what you want to test is whether the output -pass was performed in sync with the final input scan. This form of the loop -will avoid an extra output pass whenever the decoder is able (or nearly able) -to keep up with the incoming data. - -When the data transmission speed is high, you might begin a display pass, -then find that much or all of the file has arrived before you can complete -the pass. (You can detect this by noting the JPEG_REACHED_EOI return code -from jpeg_consume_input(), or equivalently by testing jpeg_input_complete().) -In this situation you may wish to abort the current display pass and start a -new one using the newly arrived information. To do so, just call -jpeg_finish_output() and then start a new pass with jpeg_start_output(). - -A variant strategy is to abort and restart display if more than one complete -scan arrives during an output pass; this can be detected by noting -JPEG_REACHED_SOS returns and/or examining cinfo.input_scan_number. This -idea should be employed with caution, however, since the display process -might never get to the bottom of the image before being aborted, resulting -in the lower part of the screen being several passes worse than the upper. -In most cases it's probably best to abort an output pass only if the whole -file has arrived and you want to begin the final output pass immediately. - -When receiving data across a communication link, we recommend always using -the current input scan number for the output target scan number; if a -higher-quality final pass is to be done, it should be started (aborting any -incomplete output pass) as soon as the end of file is received. However, -many other strategies are possible. For example, the application can examine -the parameters of the current input scan and decide whether to display it or -not. If the scan contains only chroma data, one might choose not to use it -as the target scan, expecting that the scan will be small and will arrive -quickly. To skip to the next scan, call jpeg_consume_input() until it -returns JPEG_REACHED_SOS or JPEG_REACHED_EOI. Or just use the next higher -number as the target scan for jpeg_start_output(); but that method doesn't -let you inspect the next scan's parameters before deciding to display it. - - -In buffered-image mode, jpeg_start_decompress() never performs input and -thus never suspends. An application that uses input suspension with -buffered-image mode must be prepared for suspension returns from these -routines: -* jpeg_start_output() performs input only if you request 2-pass quantization - and the target scan isn't fully read yet. (This is discussed below.) -* jpeg_read_scanlines(), as always, returns the number of scanlines that it - was able to produce before suspending. -* jpeg_finish_output() will read any markers following the target scan, - up to the end of the file or the SOS marker that begins another scan. - (But it reads no input if jpeg_consume_input() has already reached the - end of the file or a SOS marker beyond the target output scan.) -* jpeg_finish_decompress() will read until the end of file, and thus can - suspend if the end hasn't already been reached (as can be tested by - calling jpeg_input_complete()). -jpeg_start_output(), jpeg_finish_output(), and jpeg_finish_decompress() -all return TRUE if they completed their tasks, FALSE if they had to suspend. -In the event of a FALSE return, the application must load more input data -and repeat the call. Applications that use non-suspending data sources need -not check the return values of these three routines. - - -It is possible to change decoding parameters between output passes in the -buffered-image mode. The decoder library currently supports only very -limited changes of parameters. ONLY THE FOLLOWING parameter changes are -allowed after jpeg_start_decompress() is called: -* dct_method can be changed before each call to jpeg_start_output(). - For example, one could use a fast DCT method for early scans, changing - to a higher quality method for the final scan. -* dither_mode can be changed before each call to jpeg_start_output(); - of course this has no impact if not using color quantization. Typically - one would use ordered dither for initial passes, then switch to - Floyd-Steinberg dither for the final pass. Caution: changing dither mode - can cause more memory to be allocated by the library. Although the amount - of memory involved is not large (a scanline or so), it may cause the - initial max_memory_to_use specification to be exceeded, which in the worst - case would result in an out-of-memory failure. -* do_block_smoothing can be changed before each call to jpeg_start_output(). - This setting is relevant only when decoding a progressive JPEG image. - During the first DC-only scan, block smoothing provides a very "fuzzy" look - instead of the very "blocky" look seen without it; which is better seems a - matter of personal taste. But block smoothing is nearly always a win - during later stages, especially when decoding a successive-approximation - image: smoothing helps to hide the slight blockiness that otherwise shows - up on smooth gradients until the lowest coefficient bits are sent. -* Color quantization mode can be changed under the rules described below. - You *cannot* change between full-color and quantized output (because that - would alter the required I/O buffer sizes), but you can change which - quantization method is used. - -When generating color-quantized output, changing quantization method is a -very useful way of switching between high-speed and high-quality display. -The library allows you to change among its three quantization methods: -1. Single-pass quantization to a fixed color cube. - Selected by cinfo.two_pass_quantize = FALSE and cinfo.colormap = NULL. -2. Single-pass quantization to an application-supplied colormap. - Selected by setting cinfo.colormap to point to the colormap (the value of - two_pass_quantize is ignored); also set cinfo.actual_number_of_colors. -3. Two-pass quantization to a colormap chosen specifically for the image. - Selected by cinfo.two_pass_quantize = TRUE and cinfo.colormap = NULL. - (This is the default setting selected by jpeg_read_header, but it is - probably NOT what you want for the first pass of progressive display!) -These methods offer successively better quality and lesser speed. However, -only the first method is available for quantizing in non-RGB color spaces. - -IMPORTANT: because the different quantizer methods have very different -working-storage requirements, the library requires you to indicate which -one(s) you intend to use before you call jpeg_start_decompress(). (If we did -not require this, the max_memory_to_use setting would be a complete fiction.) -You do this by setting one or more of these three cinfo fields to TRUE: - enable_1pass_quant Fixed color cube colormap - enable_external_quant Externally-supplied colormap - enable_2pass_quant Two-pass custom colormap -All three are initialized FALSE by jpeg_read_header(). But -jpeg_start_decompress() automatically sets TRUE the one selected by the -current two_pass_quantize and colormap settings, so you only need to set the -enable flags for any other quantization methods you plan to change to later. - -After setting the enable flags correctly at jpeg_start_decompress() time, you -can change to any enabled quantization method by setting two_pass_quantize -and colormap properly just before calling jpeg_start_output(). The following -special rules apply: -1. You must explicitly set cinfo.colormap to NULL when switching to 1-pass - or 2-pass mode from a different mode, or when you want the 2-pass - quantizer to be re-run to generate a new colormap. -2. To switch to an external colormap, or to change to a different external - colormap than was used on the prior pass, you must call - jpeg_new_colormap() after setting cinfo.colormap. -NOTE: if you want to use the same colormap as was used in the prior pass, -you should not do either of these things. This will save some nontrivial -switchover costs. -(These requirements exist because cinfo.colormap will always be non-NULL -after completing a prior output pass, since both the 1-pass and 2-pass -quantizers set it to point to their output colormaps. Thus you have to -do one of these two things to notify the library that something has changed. -Yup, it's a bit klugy, but it's necessary to do it this way for backwards -compatibility.) - -Note that in buffered-image mode, the library generates any requested colormap -during jpeg_start_output(), not during jpeg_start_decompress(). - -When using two-pass quantization, jpeg_start_output() makes a pass over the -buffered image to determine the optimum color map; it therefore may take a -significant amount of time, whereas ordinarily it does little work. The -progress monitor hook is called during this pass, if defined. It is also -important to realize that if the specified target scan number is greater than -or equal to the current input scan number, jpeg_start_output() will attempt -to consume input as it makes this pass. If you use a suspending data source, -you need to check for a FALSE return from jpeg_start_output() under these -conditions. The combination of 2-pass quantization and a not-yet-fully-read -target scan is the only case in which jpeg_start_output() will consume input. - - -Application authors who support buffered-image mode may be tempted to use it -for all JPEG images, even single-scan ones. This will work, but it is -inefficient: there is no need to create an image-sized coefficient buffer for -single-scan images. Requesting buffered-image mode for such an image wastes -memory. Worse, it can cost time on large images, since the buffered data has -to be swapped out or written to a temporary file. If you are concerned about -maximum performance on baseline JPEG files, you should use buffered-image -mode only when the incoming file actually has multiple scans. This can be -tested by calling jpeg_has_multiple_scans(), which will return a correct -result at any time after jpeg_read_header() completes. - -It is also worth noting that when you use jpeg_consume_input() to let input -processing get ahead of output processing, the resulting pattern of access to -the coefficient buffer is quite nonsequential. It's best to use the memory -manager jmemnobs.c if you can (ie, if you have enough real or virtual main -memory). If not, at least make sure that max_memory_to_use is set as high as -possible. If the JPEG memory manager has to use a temporary file, you will -probably see a lot of disk traffic and poor performance. (This could be -improved with additional work on the memory manager, but we haven't gotten -around to it yet.) - -In some applications it may be convenient to use jpeg_consume_input() for all -input processing, including reading the initial markers; that is, you may -wish to call jpeg_consume_input() instead of jpeg_read_header() during -startup. This works, but note that you must check for JPEG_REACHED_SOS and -JPEG_REACHED_EOI return codes as the equivalent of jpeg_read_header's codes. -Once the first SOS marker has been reached, you must call -jpeg_start_decompress() before jpeg_consume_input() will consume more input; -it'll just keep returning JPEG_REACHED_SOS until you do. If you read a -tables-only file this way, jpeg_consume_input() will return JPEG_REACHED_EOI -without ever returning JPEG_REACHED_SOS; be sure to check for this case. -If this happens, the decompressor will not read any more input until you call -jpeg_abort() to reset it. It is OK to call jpeg_consume_input() even when not -using buffered-image mode, but in that case it's basically a no-op after the -initial markers have been read: it will just return JPEG_SUSPENDED. - - -Abbreviated datastreams and multiple images -------------------------------------------- - -A JPEG compression or decompression object can be reused to process multiple -images. This saves a small amount of time per image by eliminating the -"create" and "destroy" operations, but that isn't the real purpose of the -feature. Rather, reuse of an object provides support for abbreviated JPEG -datastreams. Object reuse can also simplify processing a series of images in -a single input or output file. This section explains these features. - -A JPEG file normally contains several hundred bytes worth of quantization -and Huffman tables. In a situation where many images will be stored or -transmitted with identical tables, this may represent an annoying overhead. -The JPEG standard therefore permits tables to be omitted. The standard -defines three classes of JPEG datastreams: - * "Interchange" datastreams contain an image and all tables needed to decode - the image. These are the usual kind of JPEG file. - * "Abbreviated image" datastreams contain an image, but are missing some or - all of the tables needed to decode that image. - * "Abbreviated table specification" (henceforth "tables-only") datastreams - contain only table specifications. -To decode an abbreviated image, it is necessary to load the missing table(s) -into the decoder beforehand. This can be accomplished by reading a separate -tables-only file. A variant scheme uses a series of images in which the first -image is an interchange (complete) datastream, while subsequent ones are -abbreviated and rely on the tables loaded by the first image. It is assumed -that once the decoder has read a table, it will remember that table until a -new definition for the same table number is encountered. - -It is the application designer's responsibility to figure out how to associate -the correct tables with an abbreviated image. While abbreviated datastreams -can be useful in a closed environment, their use is strongly discouraged in -any situation where data exchange with other applications might be needed. -Caveat designer. - -The JPEG library provides support for reading and writing any combination of -tables-only datastreams and abbreviated images. In both compression and -decompression objects, a quantization or Huffman table will be retained for -the lifetime of the object, unless it is overwritten by a new table definition. - - -To create abbreviated image datastreams, it is only necessary to tell the -compressor not to emit some or all of the tables it is using. Each -quantization and Huffman table struct contains a boolean field "sent_table", -which normally is initialized to FALSE. For each table used by the image, the -header-writing process emits the table and sets sent_table = TRUE unless it is -already TRUE. (In normal usage, this prevents outputting the same table -definition multiple times, as would otherwise occur because the chroma -components typically share tables.) Thus, setting this field to TRUE before -calling jpeg_start_compress() will prevent the table from being written at -all. - -If you want to create a "pure" abbreviated image file containing no tables, -just call "jpeg_suppress_tables(&cinfo, TRUE)" after constructing all the -tables. If you want to emit some but not all tables, you'll need to set the -individual sent_table fields directly. - -To create an abbreviated image, you must also call jpeg_start_compress() -with a second parameter of FALSE, not TRUE. Otherwise jpeg_start_compress() -will force all the sent_table fields to FALSE. (This is a safety feature to -prevent abbreviated images from being created accidentally.) - -To create a tables-only file, perform the same parameter setup that you -normally would, but instead of calling jpeg_start_compress() and so on, call -jpeg_write_tables(&cinfo). This will write an abbreviated datastream -containing only SOI, DQT and/or DHT markers, and EOI. All the quantization -and Huffman tables that are currently defined in the compression object will -be emitted unless their sent_tables flag is already TRUE, and then all the -sent_tables flags will be set TRUE. - -A sure-fire way to create matching tables-only and abbreviated image files -is to proceed as follows: - - create JPEG compression object - set JPEG parameters - set destination to tables-only file - jpeg_write_tables(&cinfo); - set destination to image file - jpeg_start_compress(&cinfo, FALSE); - write data... - jpeg_finish_compress(&cinfo); - -Since the JPEG parameters are not altered between writing the table file and -the abbreviated image file, the same tables are sure to be used. Of course, -you can repeat the jpeg_start_compress() ... jpeg_finish_compress() sequence -many times to produce many abbreviated image files matching the table file. - -You cannot suppress output of the computed Huffman tables when Huffman -optimization is selected. (If you could, there'd be no way to decode the -image...) Generally, you don't want to set optimize_coding = TRUE when -you are trying to produce abbreviated files. - -In some cases you might want to compress an image using tables which are -not stored in the application, but are defined in an interchange or -tables-only file readable by the application. This can be done by setting up -a JPEG decompression object to read the specification file, then copying the -tables into your compression object. See jpeg_copy_critical_parameters() -for an example of copying quantization tables. - - -To read abbreviated image files, you simply need to load the proper tables -into the decompression object before trying to read the abbreviated image. -If the proper tables are stored in the application program, you can just -allocate the table structs and fill in their contents directly. For example, -to load a fixed quantization table into table slot "n": - - if (cinfo.quant_tbl_ptrs[n] == NULL) - cinfo.quant_tbl_ptrs[n] = jpeg_alloc_quant_table((j_common_ptr) &cinfo); - quant_ptr = cinfo.quant_tbl_ptrs[n]; /* quant_ptr is JQUANT_TBL* */ - for (i = 0; i < 64; i++) { - /* Qtable[] is desired quantization table, in natural array order */ - quant_ptr->quantval[i] = Qtable[i]; - } - -Code to load a fixed Huffman table is typically (for AC table "n"): - - if (cinfo.ac_huff_tbl_ptrs[n] == NULL) - cinfo.ac_huff_tbl_ptrs[n] = jpeg_alloc_huff_table((j_common_ptr) &cinfo); - huff_ptr = cinfo.ac_huff_tbl_ptrs[n]; /* huff_ptr is JHUFF_TBL* */ - for (i = 1; i <= 16; i++) { - /* counts[i] is number of Huffman codes of length i bits, i=1..16 */ - huff_ptr->bits[i] = counts[i]; - } - for (i = 0; i < 256; i++) { - /* symbols[] is the list of Huffman symbols, in code-length order */ - huff_ptr->huffval[i] = symbols[i]; - } - -(Note that trying to set cinfo.quant_tbl_ptrs[n] to point directly at a -constant JQUANT_TBL object is not safe. If the incoming file happened to -contain a quantization table definition, your master table would get -overwritten! Instead allocate a working table copy and copy the master table -into it, as illustrated above. Ditto for Huffman tables, of course.) - -You might want to read the tables from a tables-only file, rather than -hard-wiring them into your application. The jpeg_read_header() call is -sufficient to read a tables-only file. You must pass a second parameter of -FALSE to indicate that you do not require an image to be present. Thus, the -typical scenario is - - create JPEG decompression object - set source to tables-only file - jpeg_read_header(&cinfo, FALSE); - set source to abbreviated image file - jpeg_read_header(&cinfo, TRUE); - set decompression parameters - jpeg_start_decompress(&cinfo); - read data... - jpeg_finish_decompress(&cinfo); - -In some cases, you may want to read a file without knowing whether it contains -an image or just tables. In that case, pass FALSE and check the return value -from jpeg_read_header(): it will be JPEG_HEADER_OK if an image was found, -JPEG_HEADER_TABLES_ONLY if only tables were found. (A third return value, -JPEG_SUSPENDED, is possible when using a suspending data source manager.) -Note that jpeg_read_header() will not complain if you read an abbreviated -image for which you haven't loaded the missing tables; the missing-table check -occurs later, in jpeg_start_decompress(). - - -It is possible to read a series of images from a single source file by -repeating the jpeg_read_header() ... jpeg_finish_decompress() sequence, -without releasing/recreating the JPEG object or the data source module. -(If you did reinitialize, any partial bufferload left in the data source -buffer at the end of one image would be discarded, causing you to lose the -start of the next image.) When you use this method, stored tables are -automatically carried forward, so some of the images can be abbreviated images -that depend on tables from earlier images. - -If you intend to write a series of images into a single destination file, -you might want to make a specialized data destination module that doesn't -flush the output buffer at term_destination() time. This would speed things -up by some trifling amount. Of course, you'd need to remember to flush the -buffer after the last image. You can make the later images be abbreviated -ones by passing FALSE to jpeg_start_compress(). - - -Special markers ---------------- - -Some applications may need to insert or extract special data in the JPEG -datastream. The JPEG standard provides marker types "COM" (comment) and -"APP0" through "APP15" (application) to hold application-specific data. -Unfortunately, the use of these markers is not specified by the standard. -COM markers are fairly widely used to hold user-supplied text. The JFIF file -format spec uses APP0 markers with specified initial strings to hold certain -data. Adobe applications use APP14 markers beginning with the string "Adobe" -for miscellaneous data. Other APPn markers are rarely seen, but might -contain almost anything. - -If you wish to store user-supplied text, we recommend you use COM markers -and place readable 7-bit ASCII text in them. Newline conventions are not -standardized --- expect to find LF (Unix style), CR/LF (DOS style), or CR -(Mac style). A robust COM reader should be able to cope with random binary -garbage, including nulls, since some applications generate COM markers -containing non-ASCII junk. (But yours should not be one of them.) - -For program-supplied data, use an APPn marker, and be sure to begin it with an -identifying string so that you can tell whether the marker is actually yours. -It's probably best to avoid using APP0 or APP14 for any private markers. -(NOTE: the upcoming SPIFF standard will use APP8 markers; we recommend you -not use APP8 markers for any private purposes, either.) - -Keep in mind that at most 65533 bytes can be put into one marker, but you -can have as many markers as you like. - -By default, the IJG compression library will write a JFIF APP0 marker if the -selected JPEG colorspace is grayscale or YCbCr, or an Adobe APP14 marker if -the selected colorspace is RGB, CMYK, or YCCK. You can disable this, but -we don't recommend it. The decompression library will recognize JFIF and -Adobe markers and will set the JPEG colorspace properly when one is found. - - -You can write special markers immediately following the datastream header by -calling jpeg_write_marker() after jpeg_start_compress() and before the first -call to jpeg_write_scanlines(). When you do this, the markers appear after -the SOI and the JFIF APP0 and Adobe APP14 markers (if written), but before -all else. Specify the marker type parameter as "JPEG_COM" for COM or -"JPEG_APP0 + n" for APPn. (Actually, jpeg_write_marker will let you write -any marker type, but we don't recommend writing any other kinds of marker.) -For example, to write a user comment string pointed to by comment_text: - jpeg_write_marker(cinfo, JPEG_COM, comment_text, strlen(comment_text)); - -If it's not convenient to store all the marker data in memory at once, -you can instead call jpeg_write_m_header() followed by multiple calls to -jpeg_write_m_byte(). If you do it this way, it's your responsibility to -call jpeg_write_m_byte() exactly the number of times given in the length -parameter to jpeg_write_m_header(). (This method lets you empty the -output buffer partway through a marker, which might be important when -using a suspending data destination module. In any case, if you are using -a suspending destination, you should flush its buffer after inserting -any special markers. See "I/O suspension".) - -Or, if you prefer to synthesize the marker byte sequence yourself, -you can just cram it straight into the data destination module. - -If you are writing JFIF 1.02 extension markers (thumbnail images), don't -forget to set cinfo.JFIF_minor_version = 2 so that the encoder will write the -correct JFIF version number in the JFIF header marker. The library's default -is to write version 1.01, but that's wrong if you insert any 1.02 extension -markers. (We could probably get away with just defaulting to 1.02, but there -used to be broken decoders that would complain about unknown minor version -numbers. To reduce compatibility risks it's safest not to write 1.02 unless -you are actually using 1.02 extensions.) - - -When reading, two methods of handling special markers are available: -1. You can ask the library to save the contents of COM and/or APPn markers -into memory, and then examine them at your leisure afterwards. -2. You can supply your own routine to process COM and/or APPn markers -on-the-fly as they are read. -The first method is simpler to use, especially if you are using a suspending -data source; writing a marker processor that copes with input suspension is -not easy (consider what happens if the marker is longer than your available -input buffer). However, the second method conserves memory since the marker -data need not be kept around after it's been processed. - -For either method, you'd normally set up marker handling after creating a -decompression object and before calling jpeg_read_header(), because the -markers of interest will typically be near the head of the file and so will -be scanned by jpeg_read_header. Once you've established a marker handling -method, it will be used for the life of that decompression object -(potentially many datastreams), unless you change it. Marker handling is -determined separately for COM markers and for each APPn marker code. - - -To save the contents of special markers in memory, call - jpeg_save_markers(cinfo, marker_code, length_limit) -where marker_code is the marker type to save, JPEG_COM or JPEG_APP0+n. -(To arrange to save all the special marker types, you need to call this -routine 17 times, for COM and APP0-APP15.) If the incoming marker is longer -than length_limit data bytes, only length_limit bytes will be saved; this -parameter allows you to avoid chewing up memory when you only need to see the -first few bytes of a potentially large marker. If you want to save all the -data, set length_limit to 0xFFFF; that is enough since marker lengths are only -16 bits. As a special case, setting length_limit to 0 prevents that marker -type from being saved at all. (That is the default behavior, in fact.) - -After jpeg_read_header() completes, you can examine the special markers by -following the cinfo->marker_list pointer chain. All the special markers in -the file appear in this list, in order of their occurrence in the file (but -omitting any markers of types you didn't ask for). Both the original data -length and the saved data length are recorded for each list entry; the latter -will not exceed length_limit for the particular marker type. Note that these -lengths exclude the marker length word, whereas the stored representation -within the JPEG file includes it. (Hence the maximum data length is really -only 65533.) - -It is possible that additional special markers appear in the file beyond the -SOS marker at which jpeg_read_header stops; if so, the marker list will be -extended during reading of the rest of the file. This is not expected to be -common, however. If you are short on memory you may want to reset the length -limit to zero for all marker types after finishing jpeg_read_header, to -ensure that the max_memory_to_use setting cannot be exceeded due to addition -of later markers. - -The marker list remains stored until you call jpeg_finish_decompress or -jpeg_abort, at which point the memory is freed and the list is set to empty. -(jpeg_destroy also releases the storage, of course.) - -Note that the library is internally interested in APP0 and APP14 markers; -if you try to set a small nonzero length limit on these types, the library -will silently force the length up to the minimum it wants. (But you can set -a zero length limit to prevent them from being saved at all.) Also, in a -16-bit environment, the maximum length limit may be constrained to less than -65533 by malloc() limitations. It is therefore best not to assume that the -effective length limit is exactly what you set it to be. - - -If you want to supply your own marker-reading routine, you do it by calling -jpeg_set_marker_processor(). A marker processor routine must have the -signature - boolean jpeg_marker_parser_method (j_decompress_ptr cinfo) -Although the marker code is not explicitly passed, the routine can find it -in cinfo->unread_marker. At the time of call, the marker proper has been -read from the data source module. The processor routine is responsible for -reading the marker length word and the remaining parameter bytes, if any. -Return TRUE to indicate success. (FALSE should be returned only if you are -using a suspending data source and it tells you to suspend. See the standard -marker processors in jdmarker.c for appropriate coding methods if you need to -use a suspending data source.) - -If you override the default APP0 or APP14 processors, it is up to you to -recognize JFIF and Adobe markers if you want colorspace recognition to occur -properly. We recommend copying and extending the default processors if you -want to do that. (A better idea is to save these marker types for later -examination by calling jpeg_save_markers(); that method doesn't interfere -with the library's own processing of these markers.) - -jpeg_set_marker_processor() and jpeg_save_markers() are mutually exclusive ---- if you call one it overrides any previous call to the other, for the -particular marker type specified. - -A simple example of an external COM processor can be found in djpeg.c. -Also, see jpegtran.c for an example of using jpeg_save_markers. - - -Raw (downsampled) image data ----------------------------- - -Some applications need to supply already-downsampled image data to the JPEG -compressor, or to receive raw downsampled data from the decompressor. The -library supports this requirement by allowing the application to write or -read raw data, bypassing the normal preprocessing or postprocessing steps. -The interface is different from the standard one and is somewhat harder to -use. If your interest is merely in bypassing color conversion, we recommend -that you use the standard interface and simply set jpeg_color_space = -in_color_space (or jpeg_color_space = out_color_space for decompression). -The mechanism described in this section is necessary only to supply or -receive downsampled image data, in which not all components have the same -dimensions. - - -To compress raw data, you must supply the data in the colorspace to be used -in the JPEG file (please read the earlier section on Special color spaces) -and downsampled to the sampling factors specified in the JPEG parameters. -You must supply the data in the format used internally by the JPEG library, -namely a JSAMPIMAGE array. This is an array of pointers to two-dimensional -arrays, each of type JSAMPARRAY. Each 2-D array holds the values for one -color component. This structure is necessary since the components are of -different sizes. If the image dimensions are not a multiple of the MCU size, -you must also pad the data correctly (usually, this is done by replicating -the last column and/or row). The data must be padded to a multiple of a DCT -block in each component: that is, each downsampled row must contain a -multiple of 8 valid samples, and there must be a multiple of 8 sample rows -for each component. (For applications such as conversion of digital TV -images, the standard image size is usually a multiple of the DCT block size, -so that no padding need actually be done.) - -The procedure for compression of raw data is basically the same as normal -compression, except that you call jpeg_write_raw_data() in place of -jpeg_write_scanlines(). Before calling jpeg_start_compress(), you must do -the following: - * Set cinfo->raw_data_in to TRUE. (It is set FALSE by jpeg_set_defaults().) - This notifies the library that you will be supplying raw data. - * Ensure jpeg_color_space is correct --- an explicit jpeg_set_colorspace() - call is a good idea. Note that since color conversion is bypassed, - in_color_space is ignored, except that jpeg_set_defaults() uses it to - choose the default jpeg_color_space setting. - * Ensure the sampling factors, cinfo->comp_info[i].h_samp_factor and - cinfo->comp_info[i].v_samp_factor, are correct. Since these indicate the - dimensions of the data you are supplying, it's wise to set them - explicitly, rather than assuming the library's defaults are what you want. - -To pass raw data to the library, call jpeg_write_raw_data() in place of -jpeg_write_scanlines(). The two routines work similarly except that -jpeg_write_raw_data takes a JSAMPIMAGE data array rather than JSAMPARRAY. -The scanlines count passed to and returned from jpeg_write_raw_data is -measured in terms of the component with the largest v_samp_factor. - -jpeg_write_raw_data() processes one MCU row per call, which is to say -v_samp_factor*DCTSIZE sample rows of each component. The passed num_lines -value must be at least max_v_samp_factor*DCTSIZE, and the return value will -be exactly that amount (or possibly some multiple of that amount, in future -library versions). This is true even on the last call at the bottom of the -image; don't forget to pad your data as necessary. - -The required dimensions of the supplied data can be computed for each -component as - cinfo->comp_info[i].width_in_blocks*DCTSIZE samples per row - cinfo->comp_info[i].height_in_blocks*DCTSIZE rows in image -after jpeg_start_compress() has initialized those fields. If the valid data -is smaller than this, it must be padded appropriately. For some sampling -factors and image sizes, additional dummy DCT blocks are inserted to make -the image a multiple of the MCU dimensions. The library creates such dummy -blocks itself; it does not read them from your supplied data. Therefore you -need never pad by more than DCTSIZE samples. An example may help here. -Assume 2h2v downsampling of YCbCr data, that is - cinfo->comp_info[0].h_samp_factor = 2 for Y - cinfo->comp_info[0].v_samp_factor = 2 - cinfo->comp_info[1].h_samp_factor = 1 for Cb - cinfo->comp_info[1].v_samp_factor = 1 - cinfo->comp_info[2].h_samp_factor = 1 for Cr - cinfo->comp_info[2].v_samp_factor = 1 -and suppose that the nominal image dimensions (cinfo->image_width and -cinfo->image_height) are 101x101 pixels. Then jpeg_start_compress() will -compute downsampled_width = 101 and width_in_blocks = 13 for Y, -downsampled_width = 51 and width_in_blocks = 7 for Cb and Cr (and the same -for the height fields). You must pad the Y data to at least 13*8 = 104 -columns and rows, the Cb/Cr data to at least 7*8 = 56 columns and rows. The -MCU height is max_v_samp_factor = 2 DCT rows so you must pass at least 16 -scanlines on each call to jpeg_write_raw_data(), which is to say 16 actual -sample rows of Y and 8 each of Cb and Cr. A total of 7 MCU rows are needed, -so you must pass a total of 7*16 = 112 "scanlines". The last DCT block row -of Y data is dummy, so it doesn't matter what you pass for it in the data -arrays, but the scanlines count must total up to 112 so that all of the Cb -and Cr data gets passed. - -Output suspension is supported with raw-data compression: if the data -destination module suspends, jpeg_write_raw_data() will return 0. -In this case the same data rows must be passed again on the next call. - - -Decompression with raw data output implies bypassing all postprocessing: -you cannot ask for rescaling or color quantization, for instance. More -seriously, you must deal with the color space and sampling factors present in -the incoming file. If your application only handles, say, 2h1v YCbCr data, -you must check for and fail on other color spaces or other sampling factors. -The library will not convert to a different color space for you. - -To obtain raw data output, set cinfo->raw_data_out = TRUE before -jpeg_start_decompress() (it is set FALSE by jpeg_read_header()). Be sure to -verify that the color space and sampling factors are ones you can handle. -Then call jpeg_read_raw_data() in place of jpeg_read_scanlines(). The -decompression process is otherwise the same as usual. - -jpeg_read_raw_data() returns one MCU row per call, and thus you must pass a -buffer of at least max_v_samp_factor*DCTSIZE scanlines (scanline counting is -the same as for raw-data compression). The buffer you pass must be large -enough to hold the actual data plus padding to DCT-block boundaries. As with -compression, any entirely dummy DCT blocks are not processed so you need not -allocate space for them, but the total scanline count includes them. The -above example of computing buffer dimensions for raw-data compression is -equally valid for decompression. - -Input suspension is supported with raw-data decompression: if the data source -module suspends, jpeg_read_raw_data() will return 0. You can also use -buffered-image mode to read raw data in multiple passes. - - -Really raw data: DCT coefficients ---------------------------------- - -It is possible to read or write the contents of a JPEG file as raw DCT -coefficients. This facility is mainly intended for use in lossless -transcoding between different JPEG file formats. Other possible applications -include lossless cropping of a JPEG image, lossless reassembly of a -multi-strip or multi-tile TIFF/JPEG file into a single JPEG datastream, etc. - -To read the contents of a JPEG file as DCT coefficients, open the file and do -jpeg_read_header() as usual. But instead of calling jpeg_start_decompress() -and jpeg_read_scanlines(), call jpeg_read_coefficients(). This will read the -entire image into a set of virtual coefficient-block arrays, one array per -component. The return value is a pointer to an array of virtual-array -descriptors. Each virtual array can be accessed directly using the JPEG -memory manager's access_virt_barray method (see Memory management, below, -and also read structure.doc's discussion of virtual array handling). Or, -for simple transcoding to a different JPEG file format, the array list can -just be handed directly to jpeg_write_coefficients(). - -Each block in the block arrays contains quantized coefficient values in -normal array order (not JPEG zigzag order). The block arrays contain only -DCT blocks containing real data; any entirely-dummy blocks added to fill out -interleaved MCUs at the right or bottom edges of the image are discarded -during reading and are not stored in the block arrays. (The size of each -block array can be determined from the width_in_blocks and height_in_blocks -fields of the component's comp_info entry.) This is also the data format -expected by jpeg_write_coefficients(). - -When you are done using the virtual arrays, call jpeg_finish_decompress() -to release the array storage and return the decompression object to an idle -state; or just call jpeg_destroy() if you don't need to reuse the object. - -If you use a suspending data source, jpeg_read_coefficients() will return -NULL if it is forced to suspend; a non-NULL return value indicates successful -completion. You need not test for a NULL return value when using a -non-suspending data source. - -It is also possible to call jpeg_read_coefficients() to obtain access to the -decoder's coefficient arrays during a normal decode cycle in buffered-image -mode. This frammish might be useful for progressively displaying an incoming -image and then re-encoding it without loss. To do this, decode in buffered- -image mode as discussed previously, then call jpeg_read_coefficients() after -the last jpeg_finish_output() call. The arrays will be available for your use -until you call jpeg_finish_decompress(). - - -To write the contents of a JPEG file as DCT coefficients, you must provide -the DCT coefficients stored in virtual block arrays. You can either pass -block arrays read from an input JPEG file by jpeg_read_coefficients(), or -allocate virtual arrays from the JPEG compression object and fill them -yourself. In either case, jpeg_write_coefficients() is substituted for -jpeg_start_compress() and jpeg_write_scanlines(). Thus the sequence is - * Create compression object - * Set all compression parameters as necessary - * Request virtual arrays if needed - * jpeg_write_coefficients() - * jpeg_finish_compress() - * Destroy or re-use compression object -jpeg_write_coefficients() is passed a pointer to an array of virtual block -array descriptors; the number of arrays is equal to cinfo.num_components. - -The virtual arrays need only have been requested, not realized, before -jpeg_write_coefficients() is called. A side-effect of -jpeg_write_coefficients() is to realize any virtual arrays that have been -requested from the compression object's memory manager. Thus, when obtaining -the virtual arrays from the compression object, you should fill the arrays -after calling jpeg_write_coefficients(). The data is actually written out -when you call jpeg_finish_compress(); jpeg_write_coefficients() only writes -the file header. - -When writing raw DCT coefficients, it is crucial that the JPEG quantization -tables and sampling factors match the way the data was encoded, or the -resulting file will be invalid. For transcoding from an existing JPEG file, -we recommend using jpeg_copy_critical_parameters(). This routine initializes -all the compression parameters to default values (like jpeg_set_defaults()), -then copies the critical information from a source decompression object. -The decompression object should have just been used to read the entire -JPEG input file --- that is, it should be awaiting jpeg_finish_decompress(). - -jpeg_write_coefficients() marks all tables stored in the compression object -as needing to be written to the output file (thus, it acts like -jpeg_start_compress(cinfo, TRUE)). This is for safety's sake, to avoid -emitting abbreviated JPEG files by accident. If you really want to emit an -abbreviated JPEG file, call jpeg_suppress_tables(), or set the tables' -individual sent_table flags, between calling jpeg_write_coefficients() and -jpeg_finish_compress(). - - -Progress monitoring -------------------- - -Some applications may need to regain control from the JPEG library every so -often. The typical use of this feature is to produce a percent-done bar or -other progress display. (For a simple example, see cjpeg.c or djpeg.c.) -Although you do get control back frequently during the data-transferring pass -(the jpeg_read_scanlines or jpeg_write_scanlines loop), any additional passes -will occur inside jpeg_finish_compress or jpeg_start_decompress; those -routines may take a long time to execute, and you don't get control back -until they are done. - -You can define a progress-monitor routine which will be called periodically -by the library. No guarantees are made about how often this call will occur, -so we don't recommend you use it for mouse tracking or anything like that. -At present, a call will occur once per MCU row, scanline, or sample row -group, whichever unit is convenient for the current processing mode; so the -wider the image, the longer the time between calls. During the data -transferring pass, only one call occurs per call of jpeg_read_scanlines or -jpeg_write_scanlines, so don't pass a large number of scanlines at once if -you want fine resolution in the progress count. (If you really need to use -the callback mechanism for time-critical tasks like mouse tracking, you could -insert additional calls inside some of the library's inner loops.) - -To establish a progress-monitor callback, create a struct jpeg_progress_mgr, -fill in its progress_monitor field with a pointer to your callback routine, -and set cinfo->progress to point to the struct. The callback will be called -whenever cinfo->progress is non-NULL. (This pointer is set to NULL by -jpeg_create_compress or jpeg_create_decompress; the library will not change -it thereafter. So if you allocate dynamic storage for the progress struct, -make sure it will live as long as the JPEG object does. Allocating from the -JPEG memory manager with lifetime JPOOL_PERMANENT will work nicely.) You -can use the same callback routine for both compression and decompression. - -The jpeg_progress_mgr struct contains four fields which are set by the library: - long pass_counter; /* work units completed in this pass */ - long pass_limit; /* total number of work units in this pass */ - int completed_passes; /* passes completed so far */ - int total_passes; /* total number of passes expected */ -During any one pass, pass_counter increases from 0 up to (not including) -pass_limit; the step size is usually but not necessarily 1. The pass_limit -value may change from one pass to another. The expected total number of -passes is in total_passes, and the number of passes already completed is in -completed_passes. Thus the fraction of work completed may be estimated as - completed_passes + (pass_counter/pass_limit) - -------------------------------------------- - total_passes -ignoring the fact that the passes may not be equal amounts of work. - -When decompressing, pass_limit can even change within a pass, because it -depends on the number of scans in the JPEG file, which isn't always known in -advance. The computed fraction-of-work-done may jump suddenly (if the library -discovers it has overestimated the number of scans) or even decrease (in the -opposite case). It is not wise to put great faith in the work estimate. - -When using the decompressor's buffered-image mode, the progress monitor work -estimate is likely to be completely unhelpful, because the library has no way -to know how many output passes will be demanded of it. Currently, the library -sets total_passes based on the assumption that there will be one more output -pass if the input file end hasn't yet been read (jpeg_input_complete() isn't -TRUE), but no more output passes if the file end has been reached when the -output pass is started. This means that total_passes will rise as additional -output passes are requested. If you have a way of determining the input file -size, estimating progress based on the fraction of the file that's been read -will probably be more useful than using the library's value. - - -Memory management ------------------ - -This section covers some key facts about the JPEG library's built-in memory -manager. For more info, please read structure.doc's section about the memory -manager, and consult the source code if necessary. - -All memory and temporary file allocation within the library is done via the -memory manager. If necessary, you can replace the "back end" of the memory -manager to control allocation yourself (for example, if you don't want the -library to use malloc() and free() for some reason). - -Some data is allocated "permanently" and will not be freed until the JPEG -object is destroyed. Most data is allocated "per image" and is freed by -jpeg_finish_compress, jpeg_finish_decompress, or jpeg_abort. You can call the -memory manager yourself to allocate structures that will automatically be -freed at these times. Typical code for this is - ptr = (*cinfo->mem->alloc_small) ((j_common_ptr) cinfo, JPOOL_IMAGE, size); -Use JPOOL_PERMANENT to get storage that lasts as long as the JPEG object. -Use alloc_large instead of alloc_small for anything bigger than a few Kbytes. -There are also alloc_sarray and alloc_barray routines that automatically -build 2-D sample or block arrays. - -The library's minimum space requirements to process an image depend on the -image's width, but not on its height, because the library ordinarily works -with "strip" buffers that are as wide as the image but just a few rows high. -Some operating modes (eg, two-pass color quantization) require full-image -buffers. Such buffers are treated as "virtual arrays": only the current strip -need be in memory, and the rest can be swapped out to a temporary file. - -If you use the simplest memory manager back end (jmemnobs.c), then no -temporary files are used; virtual arrays are simply malloc()'d. Images bigger -than memory can be processed only if your system supports virtual memory. -The other memory manager back ends support temporary files of various flavors -and thus work in machines without virtual memory. They may also be useful on -Unix machines if you need to process images that exceed available swap space. - -When using temporary files, the library will make the in-memory buffers for -its virtual arrays just big enough to stay within a "maximum memory" setting. -Your application can set this limit by setting cinfo->mem->max_memory_to_use -after creating the JPEG object. (Of course, there is still a minimum size for -the buffers, so the max-memory setting is effective only if it is bigger than -the minimum space needed.) If you allocate any large structures yourself, you -must allocate them before jpeg_start_compress() or jpeg_start_decompress() in -order to have them counted against the max memory limit. Also keep in mind -that space allocated with alloc_small() is ignored, on the assumption that -it's too small to be worth worrying about; so a reasonable safety margin -should be left when setting max_memory_to_use. - -If you use the jmemname.c or jmemdos.c memory manager back end, it is -important to clean up the JPEG object properly to ensure that the temporary -files get deleted. (This is especially crucial with jmemdos.c, where the -"temporary files" may be extended-memory segments; if they are not freed, -DOS will require a reboot to recover the memory.) Thus, with these memory -managers, it's a good idea to provide a signal handler that will trap any -early exit from your program. The handler should call either jpeg_abort() -or jpeg_destroy() for any active JPEG objects. A handler is not needed with -jmemnobs.c, and shouldn't be necessary with jmemansi.c or jmemmac.c either, -since the C library is supposed to take care of deleting files made with -tmpfile(). - - -Memory usage ------------- - -Working memory requirements while performing compression or decompression -depend on image dimensions, image characteristics (such as colorspace and -JPEG process), and operating mode (application-selected options). - -As of v6b, the decompressor requires: - 1. About 24K in more-or-less-fixed-size data. This varies a bit depending - on operating mode and image characteristics (particularly color vs. - grayscale), but it doesn't depend on image dimensions. - 2. Strip buffers (of size proportional to the image width) for IDCT and - upsampling results. The worst case for commonly used sampling factors - is about 34 bytes * width in pixels for a color image. A grayscale image - only needs about 8 bytes per pixel column. - 3. A full-image DCT coefficient buffer is needed to decode a multi-scan JPEG - file (including progressive JPEGs), or whenever you select buffered-image - mode. This takes 2 bytes/coefficient. At typical 2x2 sampling, that's - 3 bytes per pixel for a color image. Worst case (1x1 sampling) requires - 6 bytes/pixel. For grayscale, figure 2 bytes/pixel. - 4. To perform 2-pass color quantization, the decompressor also needs a - 128K color lookup table and a full-image pixel buffer (3 bytes/pixel). -This does not count any memory allocated by the application, such as a -buffer to hold the final output image. - -The above figures are valid for 8-bit JPEG data precision and a machine with -32-bit ints. For 12-bit JPEG data, double the size of the strip buffers and -quantization pixel buffer. The "fixed-size" data will be somewhat smaller -with 16-bit ints, larger with 64-bit ints. Also, CMYK or other unusual -color spaces will require different amounts of space. - -The full-image coefficient and pixel buffers, if needed at all, do not -have to be fully RAM resident; you can have the library use temporary -files instead when the total memory usage would exceed a limit you set. -(But if your OS supports virtual memory, it's probably better to just use -jmemnobs and let the OS do the swapping.) - -The compressor's memory requirements are similar, except that it has no need -for color quantization. Also, it needs a full-image DCT coefficient buffer -if Huffman-table optimization is asked for, even if progressive mode is not -requested. - -If you need more detailed information about memory usage in a particular -situation, you can enable the MEM_STATS code in jmemmgr.c. - - -Library compile-time options ----------------------------- - -A number of compile-time options are available by modifying jmorecfg.h. - -The JPEG standard provides for both the baseline 8-bit DCT process and -a 12-bit DCT process. The IJG code supports 12-bit lossy JPEG if you define -BITS_IN_JSAMPLE as 12 rather than 8. Note that this causes JSAMPLE to be -larger than a char, so it affects the surrounding application's image data. -The sample applications cjpeg and djpeg can support 12-bit mode only for PPM -and GIF file formats; you must disable the other file formats to compile a -12-bit cjpeg or djpeg. (install.doc has more information about that.) -At present, a 12-bit library can handle *only* 12-bit images, not both -precisions. (If you need to include both 8- and 12-bit libraries in a single -application, you could probably do it by defining NEED_SHORT_EXTERNAL_NAMES -for just one of the copies. You'd have to access the 8-bit and 12-bit copies -from separate application source files. This is untested ... if you try it, -we'd like to hear whether it works!) - -Note that a 12-bit library always compresses in Huffman optimization mode, -in order to generate valid Huffman tables. This is necessary because our -default Huffman tables only cover 8-bit data. If you need to output 12-bit -files in one pass, you'll have to supply suitable default Huffman tables. -You may also want to supply your own DCT quantization tables; the existing -quality-scaling code has been developed for 8-bit use, and probably doesn't -generate especially good tables for 12-bit. - -The maximum number of components (color channels) in the image is determined -by MAX_COMPONENTS. The JPEG standard allows up to 255 components, but we -expect that few applications will need more than four or so. - -On machines with unusual data type sizes, you may be able to improve -performance or reduce memory space by tweaking the various typedefs in -jmorecfg.h. In particular, on some RISC CPUs, access to arrays of "short"s -is quite slow; consider trading memory for speed by making JCOEF, INT16, and -UINT16 be "int" or "unsigned int". UINT8 is also a candidate to become int. -You probably don't want to make JSAMPLE be int unless you have lots of memory -to burn. - -You can reduce the size of the library by compiling out various optional -functions. To do this, undefine xxx_SUPPORTED symbols as necessary. - -You can also save a few K by not having text error messages in the library; -the standard error message table occupies about 5Kb. This is particularly -reasonable for embedded applications where there's no good way to display -a message anyway. To do this, remove the creation of the message table -(jpeg_std_message_table[]) from jerror.c, and alter format_message to do -something reasonable without it. You could output the numeric value of the -message code number, for example. If you do this, you can also save a couple -more K by modifying the TRACEMSn() macros in jerror.h to expand to nothing; -you don't need trace capability anyway, right? - - -Portability considerations --------------------------- - -The JPEG library has been written to be extremely portable; the sample -applications cjpeg and djpeg are slightly less so. This section summarizes -the design goals in this area. (If you encounter any bugs that cause the -library to be less portable than is claimed here, we'd appreciate hearing -about them.) - -The code works fine on ANSI C, C++, and pre-ANSI C compilers, using any of -the popular system include file setups, and some not-so-popular ones too. -See install.doc for configuration procedures. - -The code is not dependent on the exact sizes of the C data types. As -distributed, we make the assumptions that - char is at least 8 bits wide - short is at least 16 bits wide - int is at least 16 bits wide - long is at least 32 bits wide -(These are the minimum requirements of the ANSI C standard.) Wider types will -work fine, although memory may be used inefficiently if char is much larger -than 8 bits or short is much bigger than 16 bits. The code should work -equally well with 16- or 32-bit ints. - -In a system where these assumptions are not met, you may be able to make the -code work by modifying the typedefs in jmorecfg.h. However, you will probably -have difficulty if int is less than 16 bits wide, since references to plain -int abound in the code. - -char can be either signed or unsigned, although the code runs faster if an -unsigned char type is available. If char is wider than 8 bits, you will need -to redefine JOCTET and/or provide custom data source/destination managers so -that JOCTET represents exactly 8 bits of data on external storage. - -The JPEG library proper does not assume ASCII representation of characters. -But some of the image file I/O modules in cjpeg/djpeg do have ASCII -dependencies in file-header manipulation; so does cjpeg's select_file_type() -routine. - -The JPEG library does not rely heavily on the C library. In particular, C -stdio is used only by the data source/destination modules and the error -handler, all of which are application-replaceable. (cjpeg/djpeg are more -heavily dependent on stdio.) malloc and free are called only from the memory -manager "back end" module, so you can use a different memory allocator by -replacing that one file. - -The code generally assumes that C names must be unique in the first 15 -characters. However, global function names can be made unique in the -first 6 characters by defining NEED_SHORT_EXTERNAL_NAMES. - -More info about porting the code may be gleaned by reading jconfig.doc, -jmorecfg.h, and jinclude.h. - - -Notes for MS-DOS implementors ------------------------------ - -The IJG code is designed to work efficiently in 80x86 "small" or "medium" -memory models (i.e., data pointers are 16 bits unless explicitly declared -"far"; code pointers can be either size). You may be able to use small -model to compile cjpeg or djpeg by itself, but you will probably have to use -medium model for any larger application. This won't make much difference in -performance. You *will* take a noticeable performance hit if you use a -large-data memory model (perhaps 10%-25%), and you should avoid "huge" model -if at all possible. - -The JPEG library typically needs 2Kb-3Kb of stack space. It will also -malloc about 20K-30K of near heap space while executing (and lots of far -heap, but that doesn't count in this calculation). This figure will vary -depending on selected operating mode, and to a lesser extent on image size. -There is also about 5Kb-6Kb of constant data which will be allocated in the -near data segment (about 4Kb of this is the error message table). -Thus you have perhaps 20K available for other modules' static data and near -heap space before you need to go to a larger memory model. The C library's -static data will account for several K of this, but that still leaves a good -deal for your needs. (If you are tight on space, you could reduce the sizes -of the I/O buffers allocated by jdatasrc.c and jdatadst.c, say from 4K to -1K. Another possibility is to move the error message table to far memory; -this should be doable with only localized hacking on jerror.c.) - -About 2K of the near heap space is "permanent" memory that will not be -released until you destroy the JPEG object. This is only an issue if you -save a JPEG object between compression or decompression operations. - -Far data space may also be a tight resource when you are dealing with large -images. The most memory-intensive case is decompression with two-pass color -quantization, or single-pass quantization to an externally supplied color -map. This requires a 128Kb color lookup table plus strip buffers amounting -to about 40 bytes per column for typical sampling ratios (eg, about 25600 -bytes for a 640-pixel-wide image). You may not be able to process wide -images if you have large data structures of your own. - -Of course, all of these concerns vanish if you use a 32-bit flat-memory-model -compiler, such as DJGPP or Watcom C. We highly recommend flat model if you -can use it; the JPEG library is significantly faster in flat model. diff --git a/Build/source/extra/jpeg/ltconfig b/Build/source/extra/jpeg/ltconfig deleted file mode 100644 index 2347e694395..00000000000 --- a/Build/source/extra/jpeg/ltconfig +++ /dev/null @@ -1,1512 +0,0 @@ -#! /bin/sh - -# ltconfig - Create a system-specific libtool. -# Copyright (C) 1996-1998 Free Software Foundation, Inc. -# Gordon Matzigkeit , 1996 -# -# This file is free software; you can redistribute it and/or modify it -# under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2 of the License, or -# (at your option) any later version. -# -# This program is distributed in the hope that it will be useful, but -# WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Lane. -This file is part of the Independent JPEG Group's software. -For conditions of distribution and use, see the accompanying README file. - - -This file provides an overview of the architecture of the IJG JPEG software; -that is, the functions of the various modules in the system and the interfaces -between modules. For more precise details about any data structure or calling -convention, see the include files and comments in the source code. - -We assume that the reader is already somewhat familiar with the JPEG standard. -The README file includes references for learning about JPEG. The file -libjpeg.doc describes the library from the viewpoint of an application -programmer using the library; it's best to read that file before this one. -Also, the file coderules.doc describes the coding style conventions we use. - -In this document, JPEG-specific terminology follows the JPEG standard: - A "component" means a color channel, e.g., Red or Luminance. - A "sample" is a single component value (i.e., one number in the image data). - A "coefficient" is a frequency coefficient (a DCT transform output number). - A "block" is an 8x8 group of samples or coefficients. - An "MCU" (minimum coded unit) is an interleaved set of blocks of size - determined by the sampling factors, or a single block in a - noninterleaved scan. -We do not use the terms "pixel" and "sample" interchangeably. When we say -pixel, we mean an element of the full-size image, while a sample is an element -of the downsampled image. Thus the number of samples may vary across -components while the number of pixels does not. (This terminology is not used -rigorously throughout the code, but it is used in places where confusion would -otherwise result.) - - -*** System features *** - -The IJG distribution contains two parts: - * A subroutine library for JPEG compression and decompression. - * cjpeg/djpeg, two sample applications that use the library to transform - JFIF JPEG files to and from several other image formats. -cjpeg/djpeg are of no great intellectual complexity: they merely add a simple -command-line user interface and I/O routines for several uncompressed image -formats. This document concentrates on the library itself. - -We desire the library to be capable of supporting all JPEG baseline, extended -sequential, and progressive DCT processes. Hierarchical processes are not -supported. - -The library does not support the lossless (spatial) JPEG process. Lossless -JPEG shares little or no code with lossy JPEG, and would normally be used -without the extensive pre- and post-processing provided by this library. -We feel that lossless JPEG is better handled by a separate library. - -Within these limits, any set of compression parameters allowed by the JPEG -spec should be readable for decompression. (We can be more restrictive about -what formats we can generate.) Although the system design allows for all -parameter values, some uncommon settings are not yet implemented and may -never be; nonintegral sampling ratios are the prime example. Furthermore, -we treat 8-bit vs. 12-bit data precision as a compile-time switch, not a -run-time option, because most machines can store 8-bit pixels much more -compactly than 12-bit. - -For legal reasons, JPEG arithmetic coding is not currently supported, but -extending the library to include it would be straightforward. - -By itself, the library handles only interchange JPEG datastreams --- in -particular the widely used JFIF file format. The library can be used by -surrounding code to process interchange or abbreviated JPEG datastreams that -are embedded in more complex file formats. (For example, libtiff uses this -library to implement JPEG compression within the TIFF file format.) - -The library includes a substantial amount of code that is not covered by the -JPEG standard but is necessary for typical applications of JPEG. These -functions preprocess the image before JPEG compression or postprocess it after -decompression. They include colorspace conversion, downsampling/upsampling, -and color quantization. This code can be omitted if not needed. - -A wide range of quality vs. speed tradeoffs are possible in JPEG processing, -and even more so in decompression postprocessing. The decompression library -provides multiple implementations that cover most of the useful tradeoffs, -ranging from very-high-quality down to fast-preview operation. On the -compression side we have generally not provided low-quality choices, since -compression is normally less time-critical. It should be understood that the -low-quality modes may not meet the JPEG standard's accuracy requirements; -nonetheless, they are useful for viewers. - - -*** Portability issues *** - -Portability is an essential requirement for the library. The key portability -issues that show up at the level of system architecture are: - -1. Memory usage. We want the code to be able to run on PC-class machines -with limited memory. Images should therefore be processed sequentially (in -strips), to avoid holding the whole image in memory at once. Where a -full-image buffer is necessary, we should be able to use either virtual memory -or temporary files. - -2. Near/far pointer distinction. To run efficiently on 80x86 machines, the -code should distinguish "small" objects (kept in near data space) from -"large" ones (kept in far data space). This is an annoying restriction, but -fortunately it does not impact code quality for less brain-damaged machines, -and the source code clutter turns out to be minimal with sufficient use of -pointer typedefs. - -3. Data precision. We assume that "char" is at least 8 bits, "short" and -"int" at least 16, "long" at least 32. The code will work fine with larger -data sizes, although memory may be used inefficiently in some cases. However, -the JPEG compressed datastream must ultimately appear on external storage as a -sequence of 8-bit bytes if it is to conform to the standard. This may pose a -problem on machines where char is wider than 8 bits. The library represents -compressed data as an array of values of typedef JOCTET. If no data type -exactly 8 bits wide is available, custom data source and data destination -modules must be written to unpack and pack the chosen JOCTET datatype into -8-bit external representation. - - -*** System overview *** - -The compressor and decompressor are each divided into two main sections: -the JPEG compressor or decompressor proper, and the preprocessing or -postprocessing functions. The interface between these two sections is the -image data that the official JPEG spec regards as its input or output: this -data is in the colorspace to be used for compression, and it is downsampled -to the sampling factors to be used. The preprocessing and postprocessing -steps are responsible for converting a normal image representation to or from -this form. (Those few applications that want to deal with YCbCr downsampled -data can skip the preprocessing or postprocessing step.) - -Looking more closely, the compressor library contains the following main -elements: - - Preprocessing: - * Color space conversion (e.g., RGB to YCbCr). - * Edge expansion and downsampling. Optionally, this step can do simple - smoothing --- this is often helpful for low-quality source data. - JPEG proper: - * MCU assembly, DCT, quantization. - * Entropy coding (sequential or progressive, Huffman or arithmetic). - -In addition to these modules we need overall control, marker generation, -and support code (memory management & error handling). There is also a -module responsible for physically writing the output data --- typically -this is just an interface to fwrite(), but some applications may need to -do something else with the data. - -The decompressor library contains the following main elements: - - JPEG proper: - * Entropy decoding (sequential or progressive, Huffman or arithmetic). - * Dequantization, inverse DCT, MCU disassembly. - Postprocessing: - * Upsampling. Optionally, this step may be able to do more general - rescaling of the image. - * Color space conversion (e.g., YCbCr to RGB). This step may also - provide gamma adjustment [ currently it does not ]. - * Optional color quantization (e.g., reduction to 256 colors). - * Optional color precision reduction (e.g., 24-bit to 15-bit color). - [This feature is not currently implemented.] - -We also need overall control, marker parsing, and a data source module. -The support code (memory management & error handling) can be shared with -the compression half of the library. - -There may be several implementations of each of these elements, particularly -in the decompressor, where a wide range of speed/quality tradeoffs is very -useful. It must be understood that some of the best speedups involve -merging adjacent steps in the pipeline. For example, upsampling, color space -conversion, and color quantization might all be done at once when using a -low-quality ordered-dither technique. The system architecture is designed to -allow such merging where appropriate. - - -Note: it is convenient to regard edge expansion (padding to block boundaries) -as a preprocessing/postprocessing function, even though the JPEG spec includes -it in compression/decompression. We do this because downsampling/upsampling -can be simplified a little if they work on padded data: it's not necessary to -have special cases at the right and bottom edges. Therefore the interface -buffer is always an integral number of blocks wide and high, and we expect -compression preprocessing to pad the source data properly. Padding will occur -only to the next block (8-sample) boundary. In an interleaved-scan situation, -additional dummy blocks may be used to fill out MCUs, but the MCU assembly and -disassembly logic will create or discard these blocks internally. (This is -advantageous for speed reasons, since we avoid DCTing the dummy blocks. -It also permits a small reduction in file size, because the compressor can -choose dummy block contents so as to minimize their size in compressed form. -Finally, it makes the interface buffer specification independent of whether -the file is actually interleaved or not.) Applications that wish to deal -directly with the downsampled data must provide similar buffering and padding -for odd-sized images. - - -*** Poor man's object-oriented programming *** - -It should be clear by now that we have a lot of quasi-independent processing -steps, many of which have several possible behaviors. To avoid cluttering the -code with lots of switch statements, we use a simple form of object-style -programming to separate out the different possibilities. - -For example, two different color quantization algorithms could be implemented -as two separate modules that present the same external interface; at runtime, -the calling code will access the proper module indirectly through an "object". - -We can get the limited features we need while staying within portable C. -The basic tool is a function pointer. An "object" is just a struct -containing one or more function pointer fields, each of which corresponds to -a method name in real object-oriented languages. During initialization we -fill in the function pointers with references to whichever module we have -determined we need to use in this run. Then invocation of the module is done -by indirecting through a function pointer; on most machines this is no more -expensive than a switch statement, which would be the only other way of -making the required run-time choice. The really significant benefit, of -course, is keeping the source code clean and well structured. - -We can also arrange to have private storage that varies between different -implementations of the same kind of object. We do this by making all the -module-specific object structs be separately allocated entities, which will -be accessed via pointers in the master compression or decompression struct. -The "public" fields or methods for a given kind of object are specified by -a commonly known struct. But a module's initialization code can allocate -a larger struct that contains the common struct as its first member, plus -additional private fields. With appropriate pointer casting, the module's -internal functions can access these private fields. (For a simple example, -see jdatadst.c, which implements the external interface specified by struct -jpeg_destination_mgr, but adds extra fields.) - -(Of course this would all be a lot easier if we were using C++, but we are -not yet prepared to assume that everyone has a C++ compiler.) - -An important benefit of this scheme is that it is easy to provide multiple -versions of any method, each tuned to a particular case. While a lot of -precalculation might be done to select an optimal implementation of a method, -the cost per invocation is constant. For example, the upsampling step might -have a "generic" method, plus one or more "hardwired" methods for the most -popular sampling factors; the hardwired methods would be faster because they'd -use straight-line code instead of for-loops. The cost to determine which -method to use is paid only once, at startup, and the selection criteria are -hidden from the callers of the method. - -This plan differs a little bit from usual object-oriented structures, in that -only one instance of each object class will exist during execution. The -reason for having the class structure is that on different runs we may create -different instances (choose to execute different modules). You can think of -the term "method" as denoting the common interface presented by a particular -set of interchangeable functions, and "object" as denoting a group of related -methods, or the total shared interface behavior of a group of modules. - - -*** Overall control structure *** - -We previously mentioned the need for overall control logic in the compression -and decompression libraries. In IJG implementations prior to v5, overall -control was mostly provided by "pipeline control" modules, which proved to be -large, unwieldy, and hard to understand. To improve the situation, the -control logic has been subdivided into multiple modules. The control modules -consist of: - -1. Master control for module selection and initialization. This has two -responsibilities: - - 1A. Startup initialization at the beginning of image processing. - The individual processing modules to be used in this run are selected - and given initialization calls. - - 1B. Per-pass control. This determines how many passes will be performed - and calls each active processing module to configure itself - appropriately at the beginning of each pass. End-of-pass processing, - where necessary, is also invoked from the master control module. - - Method selection is partially distributed, in that a particular processing - module may contain several possible implementations of a particular method, - which it will select among when given its initialization call. The master - control code need only be concerned with decisions that affect more than - one module. - -2. Data buffering control. A separate control module exists for each - inter-processing-step data buffer. This module is responsible for - invoking the processing steps that write or read that data buffer. - -Each buffer controller sees the world as follows: - -input data => processing step A => buffer => processing step B => output data - | | | - ------------------ controller ------------------ - -The controller knows the dataflow requirements of steps A and B: how much data -they want to accept in one chunk and how much they output in one chunk. Its -function is to manage its buffer and call A and B at the proper times. - -A data buffer control module may itself be viewed as a processing step by a -higher-level control module; thus the control modules form a binary tree with -elementary processing steps at the leaves of the tree. - -The control modules are objects. A considerable amount of flexibility can -be had by replacing implementations of a control module. For example: -* Merging of adjacent steps in the pipeline is done by replacing a control - module and its pair of processing-step modules with a single processing- - step module. (Hence the possible merges are determined by the tree of - control modules.) -* In some processing modes, a given interstep buffer need only be a "strip" - buffer large enough to accommodate the desired data chunk sizes. In other - modes, a full-image buffer is needed and several passes are required. - The control module determines which kind of buffer is used and manipulates - virtual array buffers as needed. One or both processing steps may be - unaware of the multi-pass behavior. - -In theory, we might be able to make all of the data buffer controllers -interchangeable and provide just one set of implementations for all. In -practice, each one contains considerable special-case processing for its -particular job. The buffer controller concept should be regarded as an -overall system structuring principle, not as a complete description of the -task performed by any one controller. - - -*** Compression object structure *** - -Here is a sketch of the logical structure of the JPEG compression library: - - |-- Colorspace conversion - |-- Preprocessing controller --| - | |-- Downsampling -Main controller --| - | |-- Forward DCT, quantize - |-- Coefficient controller --| - |-- Entropy encoding - -This sketch also describes the flow of control (subroutine calls) during -typical image data processing. Each of the components shown in the diagram is -an "object" which may have several different implementations available. One -or more source code files contain the actual implementation(s) of each object. - -The objects shown above are: - -* Main controller: buffer controller for the subsampled-data buffer, which - holds the preprocessed input data. This controller invokes preprocessing to - fill the subsampled-data buffer, and JPEG compression to empty it. There is - usually no need for a full-image buffer here; a strip buffer is adequate. - -* Preprocessing controller: buffer controller for the downsampling input data - buffer, which lies between colorspace conversion and downsampling. Note - that a unified conversion/downsampling module would probably replace this - controller entirely. - -* Colorspace conversion: converts application image data into the desired - JPEG color space; also changes the data from pixel-interleaved layout to - separate component planes. Processes one pixel row at a time. - -* Downsampling: performs reduction of chroma components as required. - Optionally may perform pixel-level smoothing as well. Processes a "row - group" at a time, where a row group is defined as Vmax pixel rows of each - component before downsampling, and Vk sample rows afterwards (remember Vk - differs across components). Some downsampling or smoothing algorithms may - require context rows above and below the current row group; the - preprocessing controller is responsible for supplying these rows via proper - buffering. The downsampler is responsible for edge expansion at the right - edge (i.e., extending each sample row to a multiple of 8 samples); but the - preprocessing controller is responsible for vertical edge expansion (i.e., - duplicating the bottom sample row as needed to make a multiple of 8 rows). - -* Coefficient controller: buffer controller for the DCT-coefficient data. - This controller handles MCU assembly, including insertion of dummy DCT - blocks when needed at the right or bottom edge. When performing - Huffman-code optimization or emitting a multiscan JPEG file, this - controller is responsible for buffering the full image. The equivalent of - one fully interleaved MCU row of subsampled data is processed per call, - even when the JPEG file is noninterleaved. - -* Forward DCT and quantization: Perform DCT, quantize, and emit coefficients. - Works on one or more DCT blocks at a time. (Note: the coefficients are now - emitted in normal array order, which the entropy encoder is expected to - convert to zigzag order as necessary. Prior versions of the IJG code did - the conversion to zigzag order within the quantization step.) - -* Entropy encoding: Perform Huffman or arithmetic entropy coding and emit the - coded data to the data destination module. Works on one MCU per call. - For progressive JPEG, the same DCT blocks are fed to the entropy coder - during each pass, and the coder must emit the appropriate subset of - coefficients. - -In addition to the above objects, the compression library includes these -objects: - -* Master control: determines the number of passes required, controls overall - and per-pass initialization of the other modules. - -* Marker writing: generates JPEG markers (except for RSTn, which is emitted - by the entropy encoder when needed). - -* Data destination manager: writes the output JPEG datastream to its final - destination (e.g., a file). The destination manager supplied with the - library knows how to write to a stdio stream; for other behaviors, the - surrounding application may provide its own destination manager. - -* Memory manager: allocates and releases memory, controls virtual arrays - (with backing store management, where required). - -* Error handler: performs formatting and output of error and trace messages; - determines handling of nonfatal errors. The surrounding application may - override some or all of this object's methods to change error handling. - -* Progress monitor: supports output of "percent-done" progress reports. - This object represents an optional callback to the surrounding application: - if wanted, it must be supplied by the application. - -The error handler, destination manager, and progress monitor objects are -defined as separate objects in order to simplify application-specific -customization of the JPEG library. A surrounding application may override -individual methods or supply its own all-new implementation of one of these -objects. The object interfaces for these objects are therefore treated as -part of the application interface of the library, whereas the other objects -are internal to the library. - -The error handler and memory manager are shared by JPEG compression and -decompression; the progress monitor, if used, may be shared as well. - - -*** Decompression object structure *** - -Here is a sketch of the logical structure of the JPEG decompression library: - - |-- Entropy decoding - |-- Coefficient controller --| - | |-- Dequantize, Inverse DCT -Main controller --| - | |-- Upsampling - |-- Postprocessing controller --| |-- Colorspace conversion - |-- Color quantization - |-- Color precision reduction - -As before, this diagram also represents typical control flow. The objects -shown are: - -* Main controller: buffer controller for the subsampled-data buffer, which - holds the output of JPEG decompression proper. This controller's primary - task is to feed the postprocessing procedure. Some upsampling algorithms - may require context rows above and below the current row group; when this - is true, the main controller is responsible for managing its buffer so as - to make context rows available. In the current design, the main buffer is - always a strip buffer; a full-image buffer is never required. - -* Coefficient controller: buffer controller for the DCT-coefficient data. - This controller handles MCU disassembly, including deletion of any dummy - DCT blocks at the right or bottom edge. When reading a multiscan JPEG - file, this controller is responsible for buffering the full image. - (Buffering DCT coefficients, rather than samples, is necessary to support - progressive JPEG.) The equivalent of one fully interleaved MCU row of - subsampled data is processed per call, even when the source JPEG file is - noninterleaved. - -* Entropy decoding: Read coded data from the data source module and perform - Huffman or arithmetic entropy decoding. Works on one MCU per call. - For progressive JPEG decoding, the coefficient controller supplies the prior - coefficients of each MCU (initially all zeroes), which the entropy decoder - modifies in each scan. - -* Dequantization and inverse DCT: like it says. Note that the coefficients - buffered by the coefficient controller have NOT been dequantized; we - merge dequantization and inverse DCT into a single step for speed reasons. - When scaled-down output is asked for, simplified DCT algorithms may be used - that emit only 1x1, 2x2, or 4x4 samples per DCT block, not the full 8x8. - Works on one DCT block at a time. - -* Postprocessing controller: buffer controller for the color quantization - input buffer, when quantization is in use. (Without quantization, this - controller just calls the upsampler.) For two-pass quantization, this - controller is responsible for buffering the full-image data. - -* Upsampling: restores chroma components to full size. (May support more - general output rescaling, too. Note that if undersized DCT outputs have - been emitted by the DCT module, this module must adjust so that properly - sized outputs are created.) Works on one row group at a time. This module - also calls the color conversion module, so its top level is effectively a - buffer controller for the upsampling->color conversion buffer. However, in - all but the highest-quality operating modes, upsampling and color - conversion are likely to be merged into a single step. - -* Colorspace conversion: convert from JPEG color space to output color space, - and change data layout from separate component planes to pixel-interleaved. - Works on one pixel row at a time. - -* Color quantization: reduce the data to colormapped form, using either an - externally specified colormap or an internally generated one. This module - is not used for full-color output. Works on one pixel row at a time; may - require two passes to generate a color map. Note that the output will - always be a single component representing colormap indexes. In the current - design, the output values are JSAMPLEs, so an 8-bit compilation cannot - quantize to more than 256 colors. This is unlikely to be a problem in - practice. - -* Color reduction: this module handles color precision reduction, e.g., - generating 15-bit color (5 bits/primary) from JPEG's 24-bit output. - Not quite clear yet how this should be handled... should we merge it with - colorspace conversion??? - -Note that some high-speed operating modes might condense the entire -postprocessing sequence to a single module (upsample, color convert, and -quantize in one step). - -In addition to the above objects, the decompression library includes these -objects: - -* Master control: determines the number of passes required, controls overall - and per-pass initialization of the other modules. This is subdivided into - input and output control: jdinput.c controls only input-side processing, - while jdmaster.c handles overall initialization and output-side control. - -* Marker reading: decodes JPEG markers (except for RSTn). - -* Data source manager: supplies the input JPEG datastream. The source - manager supplied with the library knows how to read from a stdio stream; - for other behaviors, the surrounding application may provide its own source - manager. - -* Memory manager: same as for compression library. - -* Error handler: same as for compression library. - -* Progress monitor: same as for compression library. - -As with compression, the data source manager, error handler, and progress -monitor are candidates for replacement by a surrounding application. - - -*** Decompression input and output separation *** - -To support efficient incremental display of progressive JPEG files, the -decompressor is divided into two sections that can run independently: - -1. Data input includes marker parsing, entropy decoding, and input into the - coefficient controller's DCT coefficient buffer. Note that this - processing is relatively cheap and fast. - -2. Data output reads from the DCT coefficient buffer and performs the IDCT - and all postprocessing steps. - -For a progressive JPEG file, the data input processing is allowed to get -arbitrarily far ahead of the data output processing. (This occurs only -if the application calls jpeg_consume_input(); otherwise input and output -run in lockstep, since the input section is called only when the output -section needs more data.) In this way the application can avoid making -extra display passes when data is arriving faster than the display pass -can run. Furthermore, it is possible to abort an output pass without -losing anything, since the coefficient buffer is read-only as far as the -output section is concerned. See libjpeg.doc for more detail. - -A full-image coefficient array is only created if the JPEG file has multiple -scans (or if the application specifies buffered-image mode anyway). When -reading a single-scan file, the coefficient controller normally creates only -a one-MCU buffer, so input and output processing must run in lockstep in this -case. jpeg_consume_input() is effectively a no-op in this situation. - -The main impact of dividing the decompressor in this fashion is that we must -be very careful with shared variables in the cinfo data structure. Each -variable that can change during the course of decompression must be -classified as belonging to data input or data output, and each section must -look only at its own variables. For example, the data output section may not -depend on any of the variables that describe the current scan in the JPEG -file, because these may change as the data input section advances into a new -scan. - -The progress monitor is (somewhat arbitrarily) defined to treat input of the -file as one pass when buffered-image mode is not used, and to ignore data -input work completely when buffered-image mode is used. Note that the -library has no reliable way to predict the number of passes when dealing -with a progressive JPEG file, nor can it predict the number of output passes -in buffered-image mode. So the work estimate is inherently bogus anyway. - -No comparable division is currently made in the compression library, because -there isn't any real need for it. - - -*** Data formats *** - -Arrays of pixel sample values use the following data structure: - - typedef something JSAMPLE; a pixel component value, 0..MAXJSAMPLE - typedef JSAMPLE *JSAMPROW; ptr to a row of samples - typedef JSAMPROW *JSAMPARRAY; ptr to a list of rows - typedef JSAMPARRAY *JSAMPIMAGE; ptr to a list of color-component arrays - -The basic element type JSAMPLE will typically be one of unsigned char, -(signed) char, or short. Short will be used if samples wider than 8 bits are -to be supported (this is a compile-time option). Otherwise, unsigned char is -used if possible. If the compiler only supports signed chars, then it is -necessary to mask off the value when reading. Thus, all reads of JSAMPLE -values must be coded as "GETJSAMPLE(value)", where the macro will be defined -as "((value) & 0xFF)" on signed-char machines and "((int) (value))" elsewhere. - -With these conventions, JSAMPLE values can be assumed to be >= 0. This helps -simplify correct rounding during downsampling, etc. The JPEG standard's -specification that sample values run from -128..127 is accommodated by -subtracting 128 just as the sample value is copied into the source array for -the DCT step (this will be an array of signed ints). Similarly, during -decompression the output of the IDCT step will be immediately shifted back to -0..255. (NB: different values are required when 12-bit samples are in use. -The code is written in terms of MAXJSAMPLE and CENTERJSAMPLE, which will be -defined as 255 and 128 respectively in an 8-bit implementation, and as 4095 -and 2048 in a 12-bit implementation.) - -We use a pointer per row, rather than a two-dimensional JSAMPLE array. This -choice costs only a small amount of memory and has several benefits: -* Code using the data structure doesn't need to know the allocated width of - the rows. This simplifies edge expansion/compression, since we can work - in an array that's wider than the logical picture width. -* Indexing doesn't require multiplication; this is a performance win on many - machines. -* Arrays with more than 64K total elements can be supported even on machines - where malloc() cannot allocate chunks larger than 64K. -* The rows forming a component array may be allocated at different times - without extra copying. This trick allows some speedups in smoothing steps - that need access to the previous and next rows. - -Note that each color component is stored in a separate array; we don't use the -traditional layout in which the components of a pixel are stored together. -This simplifies coding of modules that work on each component independently, -because they don't need to know how many components there are. Furthermore, -we can read or write each component to a temporary file independently, which -is helpful when dealing with noninterleaved JPEG files. - -In general, a specific sample value is accessed by code such as - GETJSAMPLE(image[colorcomponent][row][col]) -where col is measured from the image left edge, but row is measured from the -first sample row currently in memory. Either of the first two indexings can -be precomputed by copying the relevant pointer. - - -Since most image-processing applications prefer to work on images in which -the components of a pixel are stored together, the data passed to or from the -surrounding application uses the traditional convention: a single pixel is -represented by N consecutive JSAMPLE values, and an image row is an array of -(# of color components)*(image width) JSAMPLEs. One or more rows of data can -be represented by a pointer of type JSAMPARRAY in this scheme. This scheme is -converted to component-wise storage inside the JPEG library. (Applications -that want to skip JPEG preprocessing or postprocessing will have to contend -with component-wise storage.) - - -Arrays of DCT-coefficient values use the following data structure: - - typedef short JCOEF; a 16-bit signed integer - typedef JCOEF JBLOCK[DCTSIZE2]; an 8x8 block of coefficients - typedef JBLOCK *JBLOCKROW; ptr to one horizontal row of 8x8 blocks - typedef JBLOCKROW *JBLOCKARRAY; ptr to a list of such rows - typedef JBLOCKARRAY *JBLOCKIMAGE; ptr to a list of color component arrays - -The underlying type is at least a 16-bit signed integer; while "short" is big -enough on all machines of interest, on some machines it is preferable to use -"int" for speed reasons, despite the storage cost. Coefficients are grouped -into 8x8 blocks (but we always use #defines DCTSIZE and DCTSIZE2 rather than -"8" and "64"). - -The contents of a coefficient block may be in either "natural" or zigzagged -order, and may be true values or divided by the quantization coefficients, -depending on where the block is in the processing pipeline. In the current -library, coefficient blocks are kept in natural order everywhere; the entropy -codecs zigzag or dezigzag the data as it is written or read. The blocks -contain quantized coefficients everywhere outside the DCT/IDCT subsystems. -(This latter decision may need to be revisited to support variable -quantization a la JPEG Part 3.) - -Notice that the allocation unit is now a row of 8x8 blocks, corresponding to -eight rows of samples. Otherwise the structure is much the same as for -samples, and for the same reasons. - -On machines where malloc() can't handle a request bigger than 64Kb, this data -structure limits us to rows of less than 512 JBLOCKs, or a picture width of -4000+ pixels. This seems an acceptable restriction. - - -On 80x86 machines, the bottom-level pointer types (JSAMPROW and JBLOCKROW) -must be declared as "far" pointers, but the upper levels can be "near" -(implying that the pointer lists are allocated in the DS segment). -We use a #define symbol FAR, which expands to the "far" keyword when -compiling on 80x86 machines and to nothing elsewhere. - - -*** Suspendable processing *** - -In some applications it is desirable to use the JPEG library as an -incremental, memory-to-memory filter. In this situation the data source or -destination may be a limited-size buffer, and we can't rely on being able to -empty or refill the buffer at arbitrary times. Instead the application would -like to have control return from the library at buffer overflow/underrun, and -then resume compression or decompression at a later time. - -This scenario is supported for simple cases. (For anything more complex, we -recommend that the application "bite the bullet" and develop real multitasking -capability.) The libjpeg.doc file goes into more detail about the usage and -limitations of this capability; here we address the implications for library -structure. - -The essence of the problem is that the entropy codec (coder or decoder) must -be prepared to stop at arbitrary times. In turn, the controllers that call -the entropy codec must be able to stop before having produced or consumed all -the data that they normally would handle in one call. That part is reasonably -straightforward: we make the controller call interfaces include "progress -counters" which indicate the number of data chunks successfully processed, and -we require callers to test the counter rather than just assume all of the data -was processed. - -Rather than trying to restart at an arbitrary point, the current Huffman -codecs are designed to restart at the beginning of the current MCU after a -suspension due to buffer overflow/underrun. At the start of each call, the -codec's internal state is loaded from permanent storage (in the JPEG object -structures) into local variables. On successful completion of the MCU, the -permanent state is updated. (This copying is not very expensive, and may even -lead to *improved* performance if the local variables can be registerized.) -If a suspension occurs, the codec simply returns without updating the state, -thus effectively reverting to the start of the MCU. Note that this implies -leaving some data unprocessed in the source/destination buffer (ie, the -compressed partial MCU). The data source/destination module interfaces are -specified so as to make this possible. This also implies that the data buffer -must be large enough to hold a worst-case compressed MCU; a couple thousand -bytes should be enough. - -In a successive-approximation AC refinement scan, the progressive Huffman -decoder has to be able to undo assignments of newly nonzero coefficients if it -suspends before the MCU is complete, since decoding requires distinguishing -previously-zero and previously-nonzero coefficients. This is a bit tedious -but probably won't have much effect on performance. Other variants of Huffman -decoding need not worry about this, since they will just store the same values -again if forced to repeat the MCU. - -This approach would probably not work for an arithmetic codec, since its -modifiable state is quite large and couldn't be copied cheaply. Instead it -would have to suspend and resume exactly at the point of the buffer end. - -The JPEG marker reader is designed to cope with suspension at an arbitrary -point. It does so by backing up to the start of the marker parameter segment, -so the data buffer must be big enough to hold the largest marker of interest. -Again, a couple KB should be adequate. (A special "skip" convention is used -to bypass COM and APPn markers, so these can be larger than the buffer size -without causing problems; otherwise a 64K buffer would be needed in the worst -case.) - -The JPEG marker writer currently does *not* cope with suspension. I feel that -this is not necessary; it is much easier simply to require the application to -ensure there is enough buffer space before starting. (An empty 2K buffer is -more than sufficient for the header markers; and ensuring there are a dozen or -two bytes available before calling jpeg_finish_compress() will suffice for the -trailer.) This would not work for writing multi-scan JPEG files, but -we simply do not intend to support that capability with suspension. - - -*** Memory manager services *** - -The JPEG library's memory manager controls allocation and deallocation of -memory, and it manages large "virtual" data arrays on machines where the -operating system does not provide virtual memory. Note that the same -memory manager serves both compression and decompression operations. - -In all cases, allocated objects are tied to a particular compression or -decompression master record, and they will be released when that master -record is destroyed. - -The memory manager does not provide explicit deallocation of objects. -Instead, objects are created in "pools" of free storage, and a whole pool -can be freed at once. This approach helps prevent storage-leak bugs, and -it speeds up operations whenever malloc/free are slow (as they often are). -The pools can be regarded as lifetime identifiers for objects. Two -pools/lifetimes are defined: - * JPOOL_PERMANENT lasts until master record is destroyed - * JPOOL_IMAGE lasts until done with image (JPEG datastream) -Permanent lifetime is used for parameters and tables that should be carried -across from one datastream to another; this includes all application-visible -parameters. Image lifetime is used for everything else. (A third lifetime, -JPOOL_PASS = one processing pass, was originally planned. However it was -dropped as not being worthwhile. The actual usage patterns are such that the -peak memory usage would be about the same anyway; and having per-pass storage -substantially complicates the virtual memory allocation rules --- see below.) - -The memory manager deals with three kinds of object: -1. "Small" objects. Typically these require no more than 10K-20K total. -2. "Large" objects. These may require tens to hundreds of K depending on - image size. Semantically they behave the same as small objects, but we - distinguish them for two reasons: - * On MS-DOS machines, large objects are referenced by FAR pointers, - small objects by NEAR pointers. - * Pool allocation heuristics may differ for large and small objects. - Note that individual "large" objects cannot exceed the size allowed by - type size_t, which may be 64K or less on some machines. -3. "Virtual" objects. These are large 2-D arrays of JSAMPLEs or JBLOCKs - (typically large enough for the entire image being processed). The - memory manager provides stripwise access to these arrays. On machines - without virtual memory, the rest of the array may be swapped out to a - temporary file. - -(Note: JSAMPARRAY and JBLOCKARRAY data structures are a combination of large -objects for the data proper and small objects for the row pointers. For -convenience and speed, the memory manager provides single routines to create -these structures. Similarly, virtual arrays include a small control block -and a JSAMPARRAY or JBLOCKARRAY working buffer, all created with one call.) - -In the present implementation, virtual arrays are only permitted to have image -lifespan. (Permanent lifespan would not be reasonable, and pass lifespan is -not very useful since a virtual array's raison d'etre is to store data for -multiple passes through the image.) We also expect that only "small" objects -will be given permanent lifespan, though this restriction is not required by -the memory manager. - -In a non-virtual-memory machine, some performance benefit can be gained by -making the in-memory buffers for virtual arrays be as large as possible. -(For small images, the buffers might fit entirely in memory, so blind -swapping would be very wasteful.) The memory manager will adjust the height -of the buffers to fit within a prespecified maximum memory usage. In order -to do this in a reasonably optimal fashion, the manager needs to allocate all -of the virtual arrays at once. Therefore, there isn't a one-step allocation -routine for virtual arrays; instead, there is a "request" routine that simply -allocates the control block, and a "realize" routine (called just once) that -determines space allocation and creates all of the actual buffers. The -realize routine must allow for space occupied by non-virtual large objects. -(We don't bother to factor in the space needed for small objects, on the -grounds that it isn't worth the trouble.) - -To support all this, we establish the following protocol for doing business -with the memory manager: - 1. Modules must request virtual arrays (which may have only image lifespan) - during the initial setup phase, i.e., in their jinit_xxx routines. - 2. All "large" objects (including JSAMPARRAYs and JBLOCKARRAYs) must also be - allocated during initial setup. - 3. realize_virt_arrays will be called at the completion of initial setup. - The above conventions ensure that sufficient information is available - for it to choose a good size for virtual array buffers. -Small objects of any lifespan may be allocated at any time. We expect that -the total space used for small objects will be small enough to be negligible -in the realize_virt_arrays computation. - -In a virtual-memory machine, we simply pretend that the available space is -infinite, thus causing realize_virt_arrays to decide that it can allocate all -the virtual arrays as full-size in-memory buffers. The overhead of the -virtual-array access protocol is very small when no swapping occurs. - -A virtual array can be specified to be "pre-zeroed"; when this flag is set, -never-yet-written sections of the array are set to zero before being made -available to the caller. If this flag is not set, never-written sections -of the array contain garbage. (This feature exists primarily because the -equivalent logic would otherwise be needed in jdcoefct.c for progressive -JPEG mode; we may as well make it available for possible other uses.) - -The first write pass on a virtual array is required to occur in top-to-bottom -order; read passes, as well as any write passes after the first one, may -access the array in any order. This restriction exists partly to simplify -the virtual array control logic, and partly because some file systems may not -support seeking beyond the current end-of-file in a temporary file. The main -implication of this restriction is that rearrangement of rows (such as -converting top-to-bottom data order to bottom-to-top) must be handled while -reading data out of the virtual array, not while putting it in. - - -*** Memory manager internal structure *** - -To isolate system dependencies as much as possible, we have broken the -memory manager into two parts. There is a reasonably system-independent -"front end" (jmemmgr.c) and a "back end" that contains only the code -likely to change across systems. All of the memory management methods -outlined above are implemented by the front end. The back end provides -the following routines for use by the front end (none of these routines -are known to the rest of the JPEG code): - -jpeg_mem_init, jpeg_mem_term system-dependent initialization/shutdown - -jpeg_get_small, jpeg_free_small interface to malloc and free library routines - (or their equivalents) - -jpeg_get_large, jpeg_free_large interface to FAR malloc/free in MSDOS machines; - else usually the same as - jpeg_get_small/jpeg_free_small - -jpeg_mem_available estimate available memory - -jpeg_open_backing_store create a backing-store object - -read_backing_store, manipulate a backing-store object -write_backing_store, -close_backing_store - -On some systems there will be more than one type of backing-store object -(specifically, in MS-DOS a backing store file might be an area of extended -memory as well as a disk file). jpeg_open_backing_store is responsible for -choosing how to implement a given object. The read/write/close routines -are method pointers in the structure that describes a given object; this -lets them be different for different object types. - -It may be necessary to ensure that backing store objects are explicitly -released upon abnormal program termination. For example, MS-DOS won't free -extended memory by itself. To support this, we will expect the main program -or surrounding application to arrange to call self_destruct (typically via -jpeg_destroy) upon abnormal termination. This may require a SIGINT signal -handler or equivalent. We don't want to have the back end module install its -own signal handler, because that would pre-empt the surrounding application's -ability to control signal handling. - -The IJG distribution includes several memory manager back end implementations. -Usually the same back end should be suitable for all applications on a given -system, but it is possible for an application to supply its own back end at -need. - - -*** Implications of DNL marker *** - -Some JPEG files may use a DNL marker to postpone definition of the image -height (this would be useful for a fax-like scanner's output, for instance). -In these files the SOF marker claims the image height is 0, and you only -find out the true image height at the end of the first scan. - -We could read these files as follows: -1. Upon seeing zero image height, replace it by 65535 (the maximum allowed). -2. When the DNL is found, update the image height in the global image - descriptor. -This implies that control modules must avoid making copies of the image -height, and must re-test for termination after each MCU row. This would -be easy enough to do. - -In cases where image-size data structures are allocated, this approach will -result in very inefficient use of virtual memory or much-larger-than-necessary -temporary files. This seems acceptable for something that probably won't be a -mainstream usage. People might have to forgo use of memory-hogging options -(such as two-pass color quantization or noninterleaved JPEG files) if they -want efficient conversion of such files. (One could improve efficiency by -demanding a user-supplied upper bound for the height, less than 65536; in most -cases it could be much less.) - -The standard also permits the SOF marker to overestimate the image height, -with a DNL to give the true, smaller height at the end of the first scan. -This would solve the space problems if the overestimate wasn't too great. -However, it implies that you don't even know whether DNL will be used. - -This leads to a couple of very serious objections: -1. Testing for a DNL marker must occur in the inner loop of the decompressor's - Huffman decoder; this implies a speed penalty whether the feature is used - or not. -2. There is no way to hide the last-minute change in image height from an - application using the decoder. Thus *every* application using the IJG - library would suffer a complexity penalty whether it cared about DNL or - not. -We currently do not support DNL because of these problems. - -A different approach is to insist that DNL-using files be preprocessed by a -separate program that reads ahead to the DNL, then goes back and fixes the SOF -marker. This is a much simpler solution and is probably far more efficient. -Even if one wants piped input, buffering the first scan of the JPEG file needs -a lot smaller temp file than is implied by the maximum-height method. For -this approach we'd simply treat DNL as a no-op in the decompressor (at most, -check that it matches the SOF image height). - -We will not worry about making the compressor capable of outputting DNL. -Something similar to the first scheme above could be applied if anyone ever -wants to make that work. diff --git a/Build/source/extra/jpeg/testimg.bmp b/Build/source/extra/jpeg/testimg.bmp

(See -the other documentation files if you wish to use the JPEG library within -your own programs.) - -If you are on a Unix machine you may prefer to read the Unix-style manual -pages in files cjpeg.1, djpeg.1, jpegtran.1, rdjpgcom.1, wrjpgcom.1. - - -INTRODUCTION - -These programs implement JPEG image compression and decompression. JPEG -(pronounced "jay-peg") is a standardized compression method for full-color -and gray-scale images. JPEG is designed to handle "real-world" scenes, -for example scanned photographs. Cartoons, line drawings, and other -non-realistic images are not JPEG's strong suit; on that sort of material -you may get poor image quality and/or little compression. - -JPEG is lossy, meaning that the output image is not necessarily identical to -the input image. Hence you should not use JPEG if you have to have identical -output bits. However, on typical real-world images, very good compression -levels can be obtained with no visible change, and amazingly high compression -is possible if you can tolerate a low-quality image. You can trade off image -quality against file size by adjusting the compressor's "quality" setting. - - -GENERAL USAGE - -We provide two programs, cjpeg to compress an image file into JPEG format, -and djpeg to decompress a JPEG file back into a conventional image format. - -On Unix-like systems, you say: - cjpeg [switches] [imagefile] >jpegfile -or - djpeg [switches] [jpegfile] >imagefile -The programs read the specified input file, or standard input if none is -named. They always write to standard output (with trace/error messages to -standard error). These conventions are handy for piping images between -programs. - -On most non-Unix systems, you say: - cjpeg [switches] imagefile jpegfile -or - djpeg [switches] jpegfile imagefile -i.e., both the input and output files are named on the command line. This -style is a little more foolproof, and it loses no functionality if you don't -have pipes. (You can get this style on Unix too, if you prefer, by defining -TWO_FILE_COMMANDLINE when you compile the programs; see install.doc.) - -You can also say: - cjpeg [switches] -outfile jpegfile imagefile -or - djpeg [switches] -outfile imagefile jpegfile -This syntax works on all systems, so it is useful for scripts. - -The currently supported image file formats are: PPM (PBMPLUS color format), -PGM (PBMPLUS gray-scale format), BMP, Targa, and RLE (Utah Raster Toolkit -format). (RLE is supported only if the URT library is available.) -cjpeg recognizes the input image format automatically, with the exception -of some Targa-format files. You have to tell djpeg which format to generate. - -JPEG files are in the defacto standard JFIF file format. There are other, -less widely used JPEG-based file formats, but we don't support them. - -All switch names may be abbreviated; for example, -grayscale may be written --gray or -gr. Most of the "basic" switches can be abbreviated to as little as -one letter. Upper and lower case are equivalent (-BMP is the same as -bmp). -British spellings are also accepted (e.g., -greyscale), though for brevity -these are not mentioned below. - - -CJPEG DETAILS - -The basic command line switches for cjpeg are: - - -quality N Scale quantization tables to adjust image quality. - Quality is 0 (worst) to 100 (best); default is 75. - (See below for more info.) - - -grayscale Create monochrome JPEG file from color input. - Be sure to use this switch when compressing a grayscale - BMP file, because cjpeg isn't bright enough to notice - whether a BMP file uses only shades of gray. By - saying -grayscale, you'll get a smaller JPEG file that - takes less time to process. - - -optimize Perform optimization of entropy encoding parameters. - Without this, default encoding parameters are used. - -optimize usually makes the JPEG file a little smaller, - but cjpeg runs somewhat slower and needs much more - memory. Image quality and speed of decompression are - unaffected by -optimize. - - -progressive Create progressive JPEG file (see below). - - -targa Input file is Targa format. Targa files that contain - an "identification" field will not be automatically - recognized by cjpeg; for such files you must specify - -targa to make cjpeg treat the input as Targa format. - For most Targa files, you won't need this switch. - -The -quality switch lets you trade off compressed file size against quality of -the reconstructed image: the higher the quality setting, the larger the JPEG -file, and the closer the output image will be to the original input. Normally -you want to use the lowest quality setting (smallest file) that decompresses -into something visually indistinguishable from the original image. For this -purpose the quality setting should be between 50 and 95; the default of 75 is -often about right. If you see defects at -quality 75, then go up 5 or 10 -counts at a time until you are happy with the output image. (The optimal -setting will vary from one image to another.) - --quality 100 will generate a quantization table of all 1's, minimizing loss -in the quantization step (but there is still information loss in subsampling, -as well as roundoff error). This setting is mainly of interest for -experimental purposes. Quality values above about 95 are NOT recommended for -normal use; the compressed file size goes up dramatically for hardly any gain -in output image quality. - -In the other direction, quality values below 50 will produce very small files -of low image quality. Settings around 5 to 10 might be useful in preparing an -index of a large image library, for example. Try -quality 2 (or so) for some -amusing Cubist effects. (Note: quality values below about 25 generate 2-byte -quantization tables, which are considered optional in the JPEG standard. -cjpeg emits a warning message when you give such a quality value, because some -other JPEG programs may be unable to decode the resulting file. Use -baseline -if you need to ensure compatibility at low quality values.) - -The -progressive switch creates a "progressive JPEG" file. In this type of -JPEG file, the data is stored in multiple scans of increasing quality. If the -file is being transmitted over a slow communications link, the decoder can use -the first scan to display a low-quality image very quickly, and can then -improve the display with each subsequent scan. The final image is exactly -equivalent to a standard JPEG file of the same quality setting, and the total -file size is about the same --- often a little smaller. CAUTION: progressive -JPEG is not yet widely implemented, so many decoders will be unable to view a -progressive JPEG file at all. - -Switches for advanced users: - - -dct int Use integer DCT method (default). - -dct fast Use fast integer DCT (less accurate). - -dct float Use floating-point DCT method. - The float method is very slightly more accurate than - the int method, but is much slower unless your machine - has very fast floating-point hardware. Also note that - results of the floating-point method may vary slightly - across machines, while the integer methods should give - the same results everywhere. The fast integer method - is much less accurate than the other two. - - -restart N Emit a JPEG restart marker every N MCU rows, or every - N MCU blocks if "B" is attached to the number. - -restart 0 (the default) means no restart markers. - - -smooth N Smooth the input image to eliminate dithering noise. - N, ranging from 1 to 100, indicates the strength of - smoothing. 0 (the default) means no smoothing. - - -maxmemory N Set limit for amount of memory to use in processing - large images. Value is in thousands of bytes, or - millions of bytes if "M" is attached to the number. - For example, -max 4m selects 4000000 bytes. If more - space is needed, temporary files will be used. - - -verbose Enable debug printout. More -v's give more printout. - or -debug Also, version information is printed at startup. - -The -restart option inserts extra markers that allow a JPEG decoder to -resynchronize after a transmission error. Without restart markers, any damage -to a compressed file will usually ruin the image from the point of the error -to the end of the image; with restart markers, the damage is usually confined -to the portion of the image up to the next restart marker. Of course, the -restart markers occupy extra space. We recommend -restart 1 for images that -will be transmitted across unreliable networks such as Usenet. - -The -smooth option filters the input to eliminate fine-scale noise. This is -often useful when converting dithered images to JPEG: a moderate smoothing -factor of 10 to 50 gets rid of dithering patterns in the input file, resulting -in a smaller JPEG file and a better-looking image. Too large a smoothing -factor will visibly blur the image, however. - -Switches for wizards: - - -baseline Force baseline-compatible quantization tables to be - generated. This clamps quantization values to 8 bits - even at low quality settings. (This switch is poorly - named, since it does not ensure that the output is - actually baseline JPEG. For example, you can use - -baseline and -progressive together.) - - -qtables file Use the quantization tables given in the specified - text file. - - -qslots N[,...] Select which quantization table to use for each color - component. - - -sample HxV[,...] Set JPEG sampling factors for each color component. - - -scans file Use the scan script given in the specified text file. - -The "wizard" switches are intended for experimentation with JPEG. If you -don't know what you are doing, DON'T USE THEM. These switches are documented -further in the file wizard.doc. - - -DJPEG DETAILS - -The basic command line switches for djpeg are: - - -colors N Reduce image to at most N colors. This reduces the - or -quantize N number of colors used in the output image, so that it - can be displayed on a colormapped display or stored in - a colormapped file format. For example, if you have - an 8-bit display, you'd need to reduce to 256 or fewer - colors. (-colors is the recommended name, -quantize - is provided only for backwards compatibility.) - - -fast Select recommended processing options for fast, low - quality output. (The default options are chosen for - highest quality output.) Currently, this is equivalent - to "-dct fast -nosmooth -onepass -dither ordered". - - -grayscale Force gray-scale output even if JPEG file is color. - Useful for viewing on monochrome displays; also, - djpeg runs noticeably faster in this mode. - - -scale M/N Scale the output image by a factor M/N. Currently - the scale factor must be 1/1, 1/2, 1/4, or 1/8. - Scaling is handy if the image is larger than your - screen; also, djpeg runs much faster when scaling - down the output. - - -bmp Select BMP output format (Windows flavor). 8-bit - colormapped format is emitted if -colors or -grayscale - is specified, or if the JPEG file is gray-scale; - otherwise, 24-bit full-color format is emitted. - - -gif Select GIF output format. Since GIF does not support - more than 256 colors, -colors 256 is assumed (unless - you specify a smaller number of colors). If you - specify -fast, the default number of colors is 216. - - -os2 Select BMP output format (OS/2 1.x flavor). 8-bit - colormapped format is emitted if -colors or -grayscale - is specified, or if the JPEG file is gray-scale; - otherwise, 24-bit full-color format is emitted. - - -pnm Select PBMPLUS (PPM/PGM) output format (this is the - default format). PGM is emitted if the JPEG file is - gray-scale or if -grayscale is specified; otherwise - PPM is emitted. - - -rle Select RLE output format. (Requires URT library.) - - -targa Select Targa output format. Gray-scale format is - emitted if the JPEG file is gray-scale or if - -grayscale is specified; otherwise, colormapped format - is emitted if -colors is specified; otherwise, 24-bit - full-color format is emitted. - -Switches for advanced users: - - -dct int Use integer DCT method (default). - -dct fast Use fast integer DCT (less accurate). - -dct float Use floating-point DCT method. - The float method is very slightly more accurate than - the int method, but is much slower unless your machine - has very fast floating-point hardware. Also note that - results of the floating-point method may vary slightly - across machines, while the integer methods should give - the same results everywhere. The fast integer method - is much less accurate than the other two. - - -dither fs Use Floyd-Steinberg dithering in color quantization. - -dither ordered Use ordered dithering in color quantization. - -dither none Do not use dithering in color quantization. - By default, Floyd-Steinberg dithering is applied when - quantizing colors; this is slow but usually produces - the best results. Ordered dither is a compromise - between speed and quality; no dithering is fast but - usually looks awful. Note that these switches have - no effect unless color quantization is being done. - Ordered dither is only available in -onepass mode. - - -map FILE Quantize to the colors used in the specified image - file. This is useful for producing multiple files - with identical color maps, or for forcing a predefined - set of colors to be used. The FILE must be a GIF - or PPM file. This option overrides -colors and - -onepass. - - -nosmooth Use a faster, lower-quality upsampling routine. - - -onepass Use one-pass instead of two-pass color quantization. - The one-pass method is faster and needs less memory, - but it produces a lower-quality image. -onepass is - ignored unless you also say -colors N. Also, - the one-pass method is always used for gray-scale - output (the two-pass method is no improvement then). - - -maxmemory N Set limit for amount of memory to use in processing - large images. Value is in thousands of bytes, or - millions of bytes if "M" is attached to the number. - For example, -max 4m selects 4000000 bytes. If more - space is needed, temporary files will be used. - - -verbose Enable debug printout. More -v's give more printout. - or -debug Also, version information is printed at startup. - - -HINTS FOR CJPEG - -Color GIF files are not the ideal input for JPEG; JPEG is really intended for -compressing full-color (24-bit) images. In particular, don't try to convert -cartoons, line drawings, and other images that have only a few distinct -colors. GIF works great on these, JPEG does not. If you want to convert a -GIF to JPEG, you should experiment with cjpeg's -quality and -smooth options -to get a satisfactory conversion. -smooth 10 or so is often helpful. - -Avoid running an image through a series of JPEG compression/decompression -cycles. Image quality loss will accumulate; after ten or so cycles the image -may be noticeably worse than it was after one cycle. It's best to use a -lossless format while manipulating an image, then convert to JPEG format when -you are ready to file the image away. - -The -optimize option to cjpeg is worth using when you are making a "final" -version for posting or archiving. It's also a win when you are using low -quality settings to make very small JPEG files; the percentage improvement -is often a lot more than it is on larger files. (At present, -optimize -mode is always selected when generating progressive JPEG files.) - -GIF input files are no longer supported, to avoid the Unisys LZW patent. -Use a Unisys-licensed program if you need to read a GIF file. (Conversion -of GIF files to JPEG is usually a bad idea anyway.) - - -HINTS FOR DJPEG - -To get a quick preview of an image, use the -grayscale and/or -scale switches. -"-grayscale -scale 1/8" is the fastest case. - -Several options are available that trade off image quality to gain speed. -"-fast" turns on the recommended settings. - -"-dct fast" and/or "-nosmooth" gain speed at a small sacrifice in quality. -When producing a color-quantized image, "-onepass -dither ordered" is fast but -much lower quality than the default behavior. "-dither none" may give -acceptable results in two-pass mode, but is seldom tolerable in one-pass mode. - -If you are fortunate enough to have very fast floating point hardware, -"-dct float" may be even faster than "-dct fast". But on most machines -"-dct float" is slower than "-dct int"; in this case it is not worth using, -because its theoretical accuracy advantage is too small to be significant -in practice. - -Two-pass color quantization requires a good deal of memory; on MS-DOS machines -it may run out of memory even with -maxmemory 0. In that case you can still -decompress, with some loss of image quality, by specifying -onepass for -one-pass quantization. - -To avoid the Unisys LZW patent, djpeg produces uncompressed GIF files. These -are larger than they should be, but are readable by standard GIF decoders. - - -HINTS FOR BOTH PROGRAMS - -If more space is needed than will fit in the available main memory (as -determined by -maxmemory), temporary files will be used. (MS-DOS versions -will try to get extended or expanded memory first.) The temporary files are -often rather large: in typical cases they occupy three bytes per pixel, for -example 3*800*600 = 1.44Mb for an 800x600 image. If you don't have enough -free disk space, leave out -progressive and -optimize (for cjpeg) or specify --onepass (for djpeg). - -On MS-DOS, the temporary files are created in the directory named by the TMP -or TEMP environment variable, or in the current directory if neither of those -exist. Amiga implementations put the temp files in the directory named by -JPEGTMP:, so be sure to assign JPEGTMP: to a disk partition with adequate free -space. - -The default memory usage limit (-maxmemory) is set when the software is -compiled. If you get an "insufficient memory" error, try specifying a smaller --maxmemory value, even -maxmemory 0 to use the absolute minimum space. You -may want to recompile with a smaller default value if this happens often. - -On machines that have "environment" variables, you can define the environment -variable JPEGMEM to set the default memory limit. The value is specified as -described for the -maxmemory switch. JPEGMEM overrides the default value -specified when the program was compiled, and itself is overridden by an -explicit -maxmemory switch. - -On MS-DOS machines, -maxmemory is the amount of main (conventional) memory to -use. (Extended or expanded memory is also used if available.) Most -DOS-specific versions of this software do their own memory space estimation -and do not need you to specify -maxmemory. - - -JPEGTRAN - -jpegtran performs various useful transformations of JPEG files. -It can translate the coded representation from one variant of JPEG to another, -for example from baseline JPEG to progressive JPEG or vice versa. It can also -perform some rearrangements of the image data, for example turning an image -from landscape to portrait format by rotation. - -jpegtran works by rearranging the compressed data (DCT coefficients), without -ever fully decoding the image. Therefore, its transformations are lossless: -there is no image degradation at all, which would not be true if you used -djpeg followed by cjpeg to accomplish the same conversion. But by the same -token, jpegtran cannot perform lossy operations such as changing the image -quality. - -jpegtran uses a command line syntax similar to cjpeg or djpeg. -On Unix-like systems, you say: - jpegtran [switches] [inputfile] >outputfile -On most non-Unix systems, you say: - jpegtran [switches] inputfile outputfile -where both the input and output files are JPEG files. - -To specify the coded JPEG representation used in the output file, -jpegtran accepts a subset of the switches recognized by cjpeg: - -optimize Perform optimization of entropy encoding parameters. - -progressive Create progressive JPEG file. - -restart N Emit a JPEG restart marker every N MCU rows, or every - N MCU blocks if "B" is attached to the number. - -scans file Use the scan script given in the specified text file. -See the previous discussion of cjpeg for more details about these switches. -If you specify none of these switches, you get a plain baseline-JPEG output -file. The quality setting and so forth are determined by the input file. - -The image can be losslessly transformed by giving one of these switches: - -flip horizontal Mirror image horizontally (left-right). - -flip vertical Mirror image vertically (top-bottom). - -rotate 90 Rotate image 90 degrees clockwise. - -rotate 180 Rotate image 180 degrees. - -rotate 270 Rotate image 270 degrees clockwise (or 90 ccw). - -transpose Transpose image (across UL-to-LR axis). - -transverse Transverse transpose (across UR-to-LL axis). - -The transpose transformation has no restrictions regarding image dimensions. -The other transformations operate rather oddly if the image dimensions are not -a multiple of the iMCU size (usually 8 or 16 pixels), because they can only -transform complete blocks of DCT coefficient data in the desired way. - -jpegtran's default behavior when transforming an odd-size image is designed -to preserve exact reversibility and mathematical consistency of the -transformation set. As stated, transpose is able to flip the entire image -area. Horizontal mirroring leaves any partial iMCU column at the right edge -untouched, but is able to flip all rows of the image. Similarly, vertical -mirroring leaves any partial iMCU row at the bottom edge untouched, but is -able to flip all columns. The other transforms can be built up as sequences -of transpose and flip operations; for consistency, their actions on edge -pixels are defined to be the same as the end result of the corresponding -transpose-and-flip sequence. - -For practical use, you may prefer to discard any untransformable edge pixels -rather than having a strange-looking strip along the right and/or bottom edges -of a transformed image. To do this, add the -trim switch: - -trim Drop non-transformable edge blocks. -Obviously, a transformation with -trim is not reversible, so strictly speaking -jpegtran with this switch is not lossless. Also, the expected mathematical -equivalences between the transformations no longer hold. For example, -"-rot 270 -trim" trims only the bottom edge, but "-rot 90 -trim" followed by -"-rot 180 -trim" trims both edges. - -Another not-strictly-lossless transformation switch is: - -grayscale Force grayscale output. -This option discards the chrominance channels if the input image is YCbCr -(ie, a standard color JPEG), resulting in a grayscale JPEG file. The -luminance channel is preserved exactly, so this is a better method of reducing -to grayscale than decompression, conversion, and recompression. This switch -is particularly handy for fixing a monochrome picture that was mistakenly -encoded as a color JPEG. (In such a case, the space savings from getting rid -of the near-empty chroma channels won't be large; but the decoding time for -a grayscale JPEG is substantially less than that for a color JPEG.) - -jpegtran also recognizes these switches that control what to do with "extra" -markers, such as comment blocks: - -copy none Copy no extra markers from source file. This setting - suppresses all comments and other excess baggage - present in the source file. - -copy comments Copy only comment markers. This setting copies - comments from the source file, but discards - any other inessential data. - -copy all Copy all extra markers. This setting preserves - miscellaneous markers found in the source file, such - as JFIF thumbnails and Photoshop settings. In some - files these extra markers can be sizable. -The default behavior is -copy comments. (Note: in IJG releases v6 and v6a, -jpegtran always did the equivalent of -copy none.) - -Additional switches recognized by jpegtran are: - -outfile filename - -maxmemory N - -verbose - -debug -These work the same as in cjpeg or djpeg. - - -THE COMMENT UTILITIES - -The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. -Although the standard doesn't actually define what COM blocks are for, they -are widely used to hold user-supplied text strings. This lets you add -annotations, titles, index terms, etc to your JPEG files, and later retrieve -them as text. COM blocks do not interfere with the image stored in the JPEG -file. The maximum size of a COM block is 64K, but you can have as many of -them as you like in one JPEG file. - -We provide two utility programs to display COM block contents and add COM -blocks to a JPEG file. - -rdjpgcom searches a JPEG file and prints the contents of any COM blocks on -standard output. The command line syntax is - rdjpgcom [-verbose] [inputfilename] -The switch "-verbose" (or just "-v") causes rdjpgcom to also display the JPEG -image dimensions. If you omit the input file name from the command line, -the JPEG file is read from standard input. (This may not work on some -operating systems, if binary data can't be read from stdin.) - -wrjpgcom adds a COM block, containing text you provide, to a JPEG file. -Ordinarily, the COM block is added after any existing COM blocks, but you -can delete the old COM blocks if you wish. wrjpgcom produces a new JPEG -file; it does not modify the input file. DO NOT try to overwrite the input -file by directing wrjpgcom's output back into it; on most systems this will -just destroy your file. - -The command line syntax for wrjpgcom is similar to cjpeg's. On Unix-like -systems, it is - wrjpgcom [switches] [inputfilename] -The output file is written to standard output. The input file comes from -the named file, or from standard input if no input file is named. - -On most non-Unix systems, the syntax is - wrjpgcom [switches] inputfilename outputfilename -where both input and output file names must be given explicitly. - -wrjpgcom understands three switches: - -replace Delete any existing COM blocks from the file. - -comment "Comment text" Supply new COM text on command line. - -cfile name Read text for new COM block from named file. -(Switch names can be abbreviated.) If you have only one line of comment text -to add, you can provide it on the command line with -comment. The comment -text must be surrounded with quotes so that it is treated as a single -argument. Longer comments can be read from a text file. - -If you give neither -comment nor -cfile, then wrjpgcom will read the comment -text from standard input. (In this case an input image file name MUST be -supplied, so that the source JPEG file comes from somewhere else.) You can -enter multiple lines, up to 64KB worth. Type an end-of-file indicator -(usually control-D or control-Z) to terminate the comment text entry. - -wrjpgcom will not add a COM block if the provided comment string is empty. -Therefore -replace -comment "" can be used to delete all COM blocks from a -file. - -These utility programs do not depend on the IJG JPEG library. In -particular, the source code for rdjpgcom is intended as an illustration of -the minimum amount of code required to parse a JPEG file header correctly. diff --git a/Build/source/extra/jpeg/wizard.doc b/Build/source/extra/jpeg/wizard.doc deleted file mode 100644 index 54170b227df..00000000000 --- a/Build/source/extra/jpeg/wizard.doc +++ /dev/null @@ -1,211 +0,0 @@ -Advanced usage instructions for the Independent JPEG Group's JPEG software -========================================================================== - -This file describes cjpeg's "switches for wizards". - -The "wizard" switches are intended for experimentation with JPEG by persons -who are reasonably knowledgeable about the JPEG standard.

The file should contain one to four tables, each of 64 elements. -The tables are implicitly numbered 0,1,etc. in order of appearance. Table -entries appear in normal array order (NOT in the zigzag order in which they -will be stored in the JPEG file). - -Quantization table files are free format, in that arbitrary whitespace can -appear between numbers. Also, comments can be included: a comment starts -with '#' and extends to the end of the line. Here is an example file that -duplicates the default quantization tables: - - # Quantization tables given in JPEG spec, section K.1 - - # This is table 0 (the luminance table): - 16 11 10 16 24 40 51 61 - 12 12 14 19 26 58 60 55 - 14 13 16 24 40 57 69 56 - 14 17 22 29 51 87 80 62 - 18 22 37 56 68 109 103 77 - 24 35 55 64 81 104 113 92 - 49 64 78 87 103 121 120 101 - 72 92 95 98 112 100 103 99 - - # This is table 1 (the chrominance table): - 17 18 24 47 99 99 99 99 - 18 21 26 66 99 99 99 99 - 24 26 56 99 99 99 99 99 - 47 66 99 99 99 99 99 99 - 99 99 99 99 99 99 99 99 - 99 99 99 99 99 99 99 99 - 99 99 99 99 99 99 99 99 - 99 99 99 99 99 99 99 99 - -If the -qtables switch is used without -quality, then the specified tables -are used exactly as-is. If both -qtables and -quality are used, then the -tables taken from the file are scaled in the same fashion that the default -tables would be scaled for that quality setting. If -baseline appears, then -the quantization values are constrained to the range 1-255. - -By default, cjpeg will use quantization table 0 for luminance components and -table 1 for chrominance components. To override this choice, use the -qslots -switch: - - -qslots N[,...] Select which quantization table to use for - each color component. - -The -qslots switch specifies a quantization table number for each color -component, in the order in which the components appear in the JPEG SOF marker. -For example, to create a separate table for each of Y,Cb,Cr, you could -provide a -qtables file that defines three quantization tables and say -"-qslots 0,1,2". If -qslots gives fewer table numbers than there are color -components, then the last table number is repeated as necessary. - - -Sampling Factor Adjustment --------------------------- - -By default, cjpeg uses 2:1 horizontal and vertical downsampling when -compressing YCbCr data, and no downsampling for all other color spaces. -You can override this default with the -sample switch: - - -sample HxV[,...] Set JPEG sampling factors for each color - component. - -The -sample switch specifies the JPEG sampling factors for each color -component, in the order in which they appear in the JPEG SOF marker. -If you specify fewer HxV pairs than there are components, the remaining -components are set to 1x1 sampling. For example, the default YCbCr setting -is equivalent to "-sample 2x2,1x1,1x1", which can be abbreviated to -"-sample 2x2". - -There are still some JPEG decoders in existence that support only 2x1 -sampling (also called 4:2:2 sampling). Compatibility with such decoders can -be achieved by specifying "-sample 2x1". This is not recommended unless -really necessary, since it increases file size and encoding/decoding time -with very little quality gain. - - -Multiple Scan / Progression Control ------------------------------------ - -By default, cjpeg emits a single-scan sequential JPEG file. The --progressive switch generates a progressive JPEG file using a default series -of progression parameters. You can create multiple-scan sequential JPEG -files or progressive JPEG files with custom progression parameters by using -the -scans switch: - - -scans file Use the scan sequence given in the named file. - -The specified file should be a text file containing a "scan script". -The script specifies the contents and ordering of the scans to be emitted. -Each entry in the script defines one scan. A scan definition specifies -the components to be included in the scan, and for progressive JPEG it also -specifies the progression parameters Ss,Se,Ah,Al for the scan. Scan -definitions are separated by semicolons (';'). A semicolon after the last -scan definition is optional. - -Each scan definition contains one to four component indexes, optionally -followed by a colon (':') and the four progressive-JPEG parameters. The -component indexes denote which color component(s) are to be transmitted in -the scan. Components are numbered in the order in which they appear in the -JPEG SOF marker, with the first component being numbered 0. (Note that these -indexes are not the "component ID" codes assigned to the components, just -positional indexes.) - -The progression parameters for each scan are: - Ss Zigzag index of first coefficient included in scan - Se Zigzag index of last coefficient included in scan - Ah Zero for first scan of a coefficient, else Al of prior scan - Al Successive approximation low bit position for scan -If the progression parameters are omitted, the values 0,63,0,0 are used, -producing a sequential JPEG file. cjpeg automatically determines whether -the script represents a progressive or sequential file, by observing whether -Ss and Se values other than 0 and 63 appear. (The -progressive switch is -not needed to specify this; in fact, it is ignored when -scans appears.) -The scan script must meet the JPEG restrictions on progression sequences. -(cjpeg checks that the spec's requirements are obeyed.) - -Scan script files are free format, in that arbitrary whitespace can appear -between numbers and around punctuation. Also, comments can be included: a -comment starts with '#' and extends to the end of the line. For additional -legibility, commas or dashes can be placed between values. (Actually, any -single punctuation character other than ':' or ';' can be inserted.) For -example, the following two scan definitions are equivalent: - 0 1 2: 0 63 0 0; - 0,1,2 : 0-63, 0,0 ; - -Here is an example of a scan script that generates a partially interleaved -sequential JPEG file: - - 0; # Y only in first scan - 1 2; # Cb and Cr in second scan - -Here is an example of a progressive scan script using only spectral selection -(no successive approximation): - - # Interleaved DC scan for Y,Cb,Cr: - 0,1,2: 0-0, 0, 0 ; - # AC scans: - 0: 1-2, 0, 0 ; # First two Y AC coefficients - 0: 3-5, 0, 0 ; # Three more - 1: 1-63, 0, 0 ; # All AC coefficients for Cb - 2: 1-63, 0, 0 ; # All AC coefficients for Cr - 0: 6-9, 0, 0 ; # More Y coefficients - 0: 10-63, 0, 0 ; # Remaining Y coefficients - -Here is an example of a successive-approximation script. This is equivalent -to the default script used by "cjpeg -progressive" for YCbCr images: - - # Initial DC scan for Y,Cb,Cr (lowest bit not sent) - 0,1,2: 0-0, 0, 1 ; - # First AC scan: send first 5 Y AC coefficients, minus 2 lowest bits: - 0: 1-5, 0, 2 ; - # Send all Cr,Cb AC coefficients, minus lowest bit: - # (chroma data is usually too small to be worth subdividing further; - # but note we send Cr first since eye is least sensitive to Cb) - 2: 1-63, 0, 1 ; - 1: 1-63, 0, 1 ; - # Send remaining Y AC coefficients, minus 2 lowest bits: - 0: 6-63, 0, 2 ; - # Send next-to-lowest bit of all Y AC coefficients: - 0: 1-63, 2, 1 ; - # At this point we've sent all but the lowest bit of all coefficients. - # Send lowest bit of DC coefficients - 0,1,2: 0-0, 1, 0 ; - # Send lowest bit of AC coefficients - 2: 1-63, 1, 0 ; - 1: 1-63, 1, 0 ; - # Y AC lowest bit scan is last; it's usually the largest scan - 0: 1-63, 1, 0 ; - -It may be worth pointing out that this script is tuned for quality settings -of around 50 to 75. For lower quality settings, you'd probably want to use -a script with fewer stages of successive approximation (otherwise the -initial scans will be really bad). For higher quality settings, you might -want to use more stages of successive approximation (so that the initial -scans are not too large). diff --git a/Build/source/extra/jpeg/wrbmp.c b/Build/source/extra/jpeg/wrbmp.c deleted file mode 100644 index 3283b0f15c2..00000000000 --- a/Build/source/extra/jpeg/wrbmp.c +++ /dev/null @@ -1,442 +0,0 @@ -/* - * wrbmp.c - * - * Copyright (C) 1994-1996, Thomas G.

A comment block is -added to the file. -.PP -The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. -Although the standard doesn't actually define what COM blocks are for, they -are widely used to hold user-supplied text strings. This lets you add -annotations, titles, index terms, etc to your JPEG files, and later retrieve -them as text. COM blocks do not interfere with the image stored in the JPEG -file. The maximum size of a COM block is 64K, but you can have as many of -them as you like in one JPEG file. -.PP -.B wrjpgcom -adds a COM block, containing text you provide, to a JPEG file. -Ordinarily, the COM block is added after any existing COM blocks; but you -can delete the old COM blocks if you wish. -.SH OPTIONS -Switch names may be abbreviated, and are not case sensitive. -.TP -.B \-replace -Delete any existing COM blocks from the file. -.TP -.BI \-comment " text" -Supply text for new COM block on command line. -.TP -.BI \-cfile " name" -Read text for new COM block from named file. -.PP -If you have only one line of comment text to add, you can provide it on the -command line with -.BR \-comment . -The comment text must be surrounded with quotes so that it is treated as a -single argument. Longer comments can be read from a text file. -.PP -If you give neither -.B \-comment -nor -.BR \-cfile , -then -.B wrjpgcom -will read the comment text from standard input. (In this case an input image -file name MUST be supplied, so that the source JPEG file comes from somewhere -else.) You can enter multiple lines, up to 64KB worth. Type an end-of-file -indicator (usually control-D) to terminate the comment text entry. -.PP -.B wrjpgcom -will not add a COM block if the provided comment string is empty. Therefore -\fB\-replace \-comment ""\fR can be used to delete all COM blocks from a file. -.SH EXAMPLES -.LP -Add a short comment to in.jpg, producing out.jpg: -.IP -.B wrjpgcom \-c -\fI"View of my back yard" in.jpg -.B > -.I out.jpg -.PP -Attach a long comment previously stored in comment.txt: -.IP -.B wrjpgcom -.I in.jpg -.B < -.I comment.txt -.B > -.I out.jpg -.PP -or equivalently -.IP -.B wrjpgcom -.B -cfile -.I comment.txt -.B < -.I in.jpg -.B > -.I out.jpg -.SH SEE ALSO -.BR cjpeg (1), -.BR djpeg (1), -.BR jpegtran (1), -.BR rdjpgcom (1) -.SH AUTHOR -Independent JPEG Group diff --git a/Build/source/extra/jpeg/wrjpgcom.c b/Build/source/extra/jpeg/wrjpgcom.c deleted file mode 100644 index 8c04b055120..00000000000 --- a/Build/source/extra/jpeg/wrjpgcom.c +++ /dev/null @@ -1,583 +0,0 @@ -/* - * wrjpgcom.c - * - * Copyright (C) 1994-1997, Thomas G.

This compression - method searches for as much of the current string of bytes (up to a length - of ~320) in the previous 4K or 8K bytes. If it doesn't find any matches - (of at least length 2 or 3), it codes the next byte. Otherwise, it codes - the length of the matched string and its distance backwards from the - current position. Single bytes ("literals") are preceded by a one (a - single bit) and are either uncoded (the eight bits go directly into the - compressed stream for a total of nine bits) or Huffman coded with a - supplied literal code tree. If literals are coded, then the minimum match - length is three, otherwise it is two. - - There are therefore four kinds of imploded streams: 8K search with coded - literals (min match = 3), 4K search with coded literals (min match = 3), - 8K with uncoded literals (min match = 2), and 4K with uncoded literals - (min match = 2). The kind of stream is identified in two bits of a - general purpose bit flag that is outside of the compressed stream. - - Distance-length pairs for matched strings are preceded by a zero bit (to - distinguish them from literals) and are always coded. The distance comes - first and is either the low six (4K) or low seven (8K) bits of the - distance (uncoded), followed by the high six bits of the distance coded. - Then the length is six bits coded (0..63 + min match length), and if the - maximum such length is coded, then it's followed by another eight bits - (uncoded) to be added to the coded length. This gives a match length - range of 2..320 or 3..321 bytes. - - The literal, length, and distance codes are all represented in a slightly - compressed form themselves. What is sent are the lengths of the codes for - each value, which is sufficient to construct the codes. Each byte of the - code representation is the code length (the low four bits representing - 1..16), and the number of values sequentially with that length (the high - four bits also representing 1..16). There are 256 literal code values (if - literals are coded), 64 length code values, and 64 distance code values, - in that order at the beginning of the compressed stream. Each set of code - values is preceded (redundantly) with a byte indicating how many bytes are - in the code description that follows, in the range 1..256. - - The codes themselves are decoded using tables made by huft_build() from - the bit lengths.

Since the central di- - rectory lies at the end of the zipfile and the member files lie at the - beginning or middle or wherever, it is not very desirable to simply - read a central directory entry, jump to the member and extract it, and - then jump back to the central directory. In the case of a large zipfile - this would lead to a whole lot of disk-grinding, especially if each mem- - ber file is small. Instead, we read from the central directory the per- - tinent information for a block of files, then go extract/test the whole - block. Thus this routine contains two small(er) loops within a very - large outer loop: the first of the small ones reads a block of files - from the central directory; the second extracts or tests each file; and - the outer one loops over blocks. There's some file-pointer positioning - stuff in between, but that's about it. Btw, it's because of this jump- - ing around that we can afford to be lenient if an error occurs in one of - the member files: we should still be able to go find the other members, - since we know the offset of each from the beginning of the zipfile. - ---------------------------------------------------------------------------*/ - - G.pInfo = G.info; - members_remaining = (unsigned)G.ecrec.total_entries_central_dir; - -#if CRYPT - G.newzip = TRUE; -#endif -#ifndef SFX - G.reported_backslash = FALSE; -#endif - - /* malloc space for check on unmatched filespecs (OK if one or both NULL) */ - if (G.filespecs > 0 && - (fn_matched=(int *)malloc(G.filespecs*sizeof(int))) != (int *)NULL) - for (i = 0; i < G.filespecs; ++i) - fn_matched[i] = FALSE; - if (G.xfilespecs > 0 && - (xn_matched=(int *)malloc(G.xfilespecs*sizeof(int))) != (int *)NULL) - for (i = 0; i < G.xfilespecs; ++i) - xn_matched[i] = FALSE; - -/*--------------------------------------------------------------------------- - Begin main loop over blocks of member files.

This must - also be done by any API function that jumps into the middle of the - code. - - The DESTROYGLOBALS; statement should be inserted before EVERY "EXIT(n)". - Naturally, it also needs to be put before any API returns as well. - In fact, it's much more important in API functions since the process - will NOT end, and therefore the memory WON'T automatically be freed - by the operating system. - - USING VARIABLES FROM THE STRUCTURE - ---------------------------------- - - All global variables must now be prefixed with `G.' which is either a - global struct (in which case it should be the only global variable) or - a macro for the value of a local pointer variable that is passed from - function to function. Yes, this is a pain. But it's the only way to - allow full reentrancy. - - ADDING VARIABLES TO THE STRUCTURE - --------------------------------- - - If you make the inclusion of any variables conditional, be sure to only - check macros that are GUARANTEED to be included in every module. - For instance, newzip and pwdarg are needed only if CRYPT is TRUE, - but this is defined after unzip.h has been read. If you are not careful, - some modules will expect your variable to be part of this struct while - others won't. This will cause BIG problems. (Inexplicable crashes at - strange times, car fires, etc.) When in doubt, always include it! - - Note also that UnZipSFX needs a few variables that UnZip doesn't. However, - it also includes some object files from UnZip. If we were to conditionally - include the extra variables that UnZipSFX needs, the object files from - UnZip would not mesh with the UnZipSFX object files. Result: we just - include the UnZipSFX variables every time. (It's only an extra 4 bytes - so who cares!) - - ADDING FUNCTIONS - ---------------- - - To support this new global struct, all functions must now conditionally - pass the globals pointer (pG) to each other. This is supported by 5 macros: - __GPRO, __GPRO__, __G, __G__ and __GDEF. A function that needs no other - parameters would look like this: - - int extract_or_test_files(__G) - __GDEF - { - ... stuff ... - } - - A function with other parameters would look like: - - int memextract(__G__ tgt, tgtsize, src, srcsize) - __GDEF - uch *tgt, *src; - ulg tgtsize, srcsize; - { - ... stuff ... - } - - In the Function Prototypes section of unzpriv.h, you should use __GPRO and - __GPRO__ instead: - - int uz_opts OF((__GPRO__ int *pargc, char ***pargv)); - int process_zipfiles OF((__GPRO)); - - Note that there is NO comma after __G__ or __GPRO__ and no semi-colon after - __GDEF. I wish there was another way but I don't think there is. - - - TESTING THE CODE - ----------------- - - Whether your platform requires reentrancy or not, you should always try - building with REENTRANT defined if any functions have been added. It is - pretty easy to forget a __G__ or a __GDEF and this mistake will only show - up if REENTRANT is defined. All platforms should run with REENTRANT - defined. Platforms that can't take advantage of it will just be paying - a performance penalty needlessly. - - SIGNAL MADNESS - -------------- - - This whole pointer passing scheme falls apart when it comes to SIGNALs. - I handle this situation 2 ways right now. If you define USETHREADID, - UnZip will include a 64-entry table. Each entry can hold a global - pointer and thread ID for one thread. This should allow up to 64 - threads to access UnZip simultaneously. Calling DESTROYGLOBALS() - will free the global struct and zero the table entry. If somebody - forgets to call DESTROYGLOBALS(), this table will eventually fill up - and UnZip will exit with an error message. A good way to test your - code to make sure you didn't forget a DESTROYGLOBALS() is to change - THREADID_ENTRIES to 3 or 4 in globals.c, making the table real small. - Then make a small test program that calls your API a dozen times. - - Those platforms that don't have threads still need to be able to compile - with REENTRANT defined to test and see if new code is correctly written - to work either way. For these platforms, I simply keep a global pointer - called GG that points to the Globals structure. Good enough for testing. - - I believe that NT has thread level storage. This could probably be used - to store a global pointer for the sake of the signal handler more cleanly - than my table approach. - - ---------------------------------------------------------------------------*/ - -#ifndef __globals_h -#define __globals_h - -#ifdef USE_ZLIB -# include "zlib.h" -#endif - - -/*************/ -/* Globals */ -/*************/ - -typedef struct Globals { -#ifdef DLL - zvoid *callerglobs; /* pointer to structure of pass-through global vars */ -#endif - - /* command options of general use */ - UzpOpts UzO; /* command options of general use */ - -#ifndef FUNZIP - /* command options specific to the high level command line interface */ -#ifdef MORE - int M_flag; /* -M: built-in "more" function */ -#endif - - /* internal flags and general globals */ -#ifdef MORE - int height; /* check for SIGWINCH, etc., eventually... */ -#endif /* (take line-wrapping into account?) */ -#if (defined(IZ_CHECK_TZ) && defined(USE_EF_UT_TIME)) - int tz_is_valid; /* indicates that timezone info can be used */ -#endif -#ifdef WINDLL - int prompt_always; /* prompt to overwrite if TRUE */ -#endif - int noargs; /* did true command line have *any* arguments? */ - unsigned filespecs; /* number of real file specifications to be matched */ - unsigned xfilespecs; /* number of excluded filespecs to be matched */ - int process_all_files; - int create_dirs; /* used by main(), mapname(), checkdir() */ - int extract_flag; - int newzip; /* reset in extract.c; used in crypt.c */ - LONGINT real_ecrec_offset; - LONGINT expect_ecrec_offset; - long csize; /* used by decompr.

The compression - method searches for as much of the current string of bytes (up to a - length of 258) in the previous 32K bytes. If it doesn't find any - matches (of at least length 3), it codes the next byte. Otherwise, it - codes the length of the matched string and its distance backwards from - the current position. There is a single Huffman code that codes both - single bytes (called "literals") and match lengths. A second Huffman - code codes the distance information, which follows a length code. Each - length or distance code actually represents a base value and a number - of "extra" (sometimes zero) bits to get to add to the base value. At - the end of each deflated block is a special end-of-block (EOB) literal/ - length code. The decoding process is basically: get a literal/length - code; if EOB then done; if a literal, emit the decoded byte; if a - length then get the distance and emit the referred-to bytes from the - sliding window of previously emitted data. - - There are (currently) three kinds of inflate blocks: stored, fixed, and - dynamic. The compressor outputs a chunk of data at a time and decides - which method to use on a chunk-by-chunk basis. A chunk might typically - be 32K to 64K, uncompressed. If the chunk is uncompressible, then the - "stored" method is used. In this case, the bytes are simply stored as - is, eight bits per byte, with none of the above coding. The bytes are - preceded by a count, since there is no longer an EOB code. - - If the data are compressible, then either the fixed or dynamic methods - are used. In the dynamic method, the compressed data are preceded by - an encoding of the literal/length and distance Huffman codes that are - to be used to decode this block. The representation is itself Huffman - coded, and so is preceded by a description of that code. These code - descriptions take up a little space, and so for small blocks, there is - a predefined set of codes, called the fixed codes. The fixed method is - used if the block ends up smaller that way (usually for quite small - chunks); otherwise the dynamic method is used. In the latter case, the - codes are customized to the probabilities in the current block and so - can code it much better than the pre-determined fixed codes can. - - The Huffman codes themselves are decoded using a multi-level table - lookup, in order to maximize the speed of decoding plus the speed of - building the decoding tables. See the comments below that precede the - lbits and dbits tuning parameters. - - GRR: return values(?) - 0 OK - 1 incomplete table - 2 bad input - 3 not enough memory - */ - - -/* - Notes beyond the 1.93a appnote.txt: - - 1. Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12. Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths. It is possible (and advantageous) for - a repeat code (16, 17, or 18) to go across the boundary between - the two sets of lengths. - */ - - -#define PKZIP_BUG_WORKAROUND /* PKZIP 1.93a problem--live with it */ - -/* - inflate.h must supply the uch slide[WSIZE] array, the zvoid typedef - (void if (void *) is accepted, else char) and the NEXTBYTE, - FLUSH() and memzero macros.

The most common codes are necessarily the - shortest codes, so those codes dominate the decoding time, and hence - the speed. The idea is you can have a shorter table that decodes the - shorter, more probable codes, and then point to subsidiary tables for - the longer codes. The time it costs to decode the longer codes is - then traded against the time it takes to make longer tables. - - This results of this trade are in the variables lbits and dbits - below. lbits is the number of bits the first level table for literal/ - length codes can decode in one step, and dbits is the same thing for - the distance codes. Subsequent tables are also less than or equal to - those sizes. These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each. The literal/length table - codes 286 possible values, or in a flat code, a little over eight - bits. The distance table codes 30 possible values, or a little less - than five bits, flat. The optimum values for speed end up being - about one bit more than those, so lbits is 8+1 and dbits is 5+1. - The optimum values may differ though from machine to machine, and - possibly even between compilers.

(From reading the patent, it appears - that a pure LZW decompressor is *not* covered, but this claim has - not been tested in court, and Unisys is reported to believe other- - wise.) It is therefore the responsibility of the user to acquire - whatever license(s) may be required for legal use of this code. - - THE INFO-ZIP GROUP DISCLAIMS ALL LIABILITY FOR USE OF THIS CODE - IN VIOLATION OF APPLICABLE PATENT LAW. - - - Shrinking is basically a dynamic LZW algorithm with allowed code sizes of - up to 13 bits; in addition, there is provision for partial clearing of - leaf nodes. PKWARE uses the special code 256 (decimal) to indicate a - change in code size or a partial clear of the code tree: 256,1 for the - former and 256,2 for the latter. [Note that partial clearing can "orphan" - nodes: the parent-to-be can be cleared before its new child is added, - but the child is added anyway (as an orphan, as though the parent still - existed). When the tree fills up to the point where the parent node is - reused, the orphan is effectively "adopted." Versions prior to 1.05 were - affected more due to greater use of pointers (to children and siblings - as well as parents).] - - This replacement version of unshrink.c was written from scratch. It is - based only on the algorithms described in Mark Nelson's _The Data Compres- - sion Book_ and in Terry Welch's original paper in the June 1984 issue of - IEEE _Computer_; no existing source code, including any in Nelson's book, - was used. - - Memory requirements have been reduced in this version and are now no more - than the original Sam Smith code. This is still larger than any of the - other algorithms: at a minimum, 8K+8K+16K (stack+values+parents) assuming - 16-bit short ints, and this does not even include the output buffer (the - other algorithms leave the uncompressed data in the work area, typically - called slide[]). For machines with a 64KB data space this is a problem, - particularly when text conversion is required and line endings have more - than one character. UnZip's solution is to use two roughly equal halves - of outbuf for the ASCII conversion in such a case; the "unshrink" argument - to flush() signals that this is the case. - - For large-memory machines, a second outbuf is allocated for translations, - but only if unshrinking and only if translations are required. - - | binary mode | text mode - --------------------------------------------------- - big mem | big outbuf | big outbuf + big outbuf2 <- malloc'd here - small mem | small outbuf | half + half small outbuf - - Copyright 1994, 1995 Greg Roelofs.
