-Subject: ANNOUNCE: Xpdf 3.02 - a PDF viewer for X
-
-
-Glyph & Cog, LLC is pleased to announce a new version of Xpdf, the
-open source Portable Document Format (PDF) viewer for X. The Xpdf
-project also includes a PDF text extractor, PDF-to-PostScript
-converter, and various other utilities.
-
-Xpdf runs under the X Window System on Unix, VMS, and OS/2. The non-X
-components (pdftops, pdftotext, etc.) also run on Win32 systems and
-should run on pretty much any system with a decent C++ compiler.
-
-Major changes:
-* Anti-aliased vector graphics, including stroke adjustment.
-* Support for PDF 1.6 and PDF 1.7, including AES decryption and
- OpenType fonts.
-* User-configurable key/mouse bindings.
-* Improved full-screen mode, with the ability to toggle on the fly.
-
-See the `CHANGES' file for a complete list of changes.
-
-Source (C++ and C) is available, and it should be fairly easy to
-compile for UNIX, VMS, OS/2, and Win32.
-
-More information, source code, and precompiled binaries are on the
-xpdf web page and ftp site:
-
- http://www.foolabs.com/xpdf/
- ftp://ftp.foolabs.com/pub/xpdf/
-
-For information on commercial licensing and consulting, please see the
-Glyph & Cog web site:

-Many minor bug fixes and optimizations.
-
-
-0.4 (96-apr-24)
----------------
-Implemented DCT filter.
-Implemented PostScript output; wrote pdftops program.
-Implemented links.
-Implemented font rotation -- I was wrong: X11R6 servers *do* support

-Added bindings for Home/End, Page Up/Down, arrow keys.
-Added initialZoom resource and -z option.
-Added geometry resource and -g option.
-Fixed image size off-by-one bug.
-Fixed bug where page content is reference to an array of streams.
-Cleaned up uninitialized variables which were causing random problems
- on various platforms.
-Manually skip whitespace before calling atoi() for startxref.
-Replaced calls to XrmCombineFileDatabase() with calls to
- XrmGetFileDatabase() and XrmMergeDatabases() so it will work under
- older versions of X.
-Fixed problem with reading multiple xref tables in updated PDF files.
-Check for encryption and print appropriate error message.
-Rudimentary dithering of images.
-Fixed bug in CCITTFax filter (pass mode followed by horizontal mode).
-Optimized drawImage() and drawImageMask().
-Changed several things to ease porting:
- - changed '__inline' to 'inline' (to adhere to the ANSI standard)
- - surrounded interface/implementation pragmas with #ifdef _GNUC__
- - got rid of empty array initializer lists
- - moved Operator type definition from Gfx.cc to Gfx.h
- - renamed String, uint, etc.
- - ability to uncompress to file (NO_POPEN and USE_GZIP flags)
- - added definitions of XK_Page_Up/Down and XPointer for old versions
- of X
-For VMS port:
- - use correct Xdefaults name for VMS, get rid of ltkGetHomeDir()
- - added '#include <stddef.h>' before all X includes
- - renamed files with multiple periods in their names
-Fixed window resizing infinite oscillation bug.
-Fixed problem with string-type (as opposed to stream-type) indexed
- color space lookup tables (which are used in inline images).
-If an X font is not found, try smaller and then larger sizes (this is
- useful for old or broken X servers which can't scale bitmap fonts).
-Added -rgb (color cube size) option.
-Various minor bug fixes.
-
-
-0.5 (96-may-23)
----------------
-Fixed bug in LTKWindow which broke the remote server mode.
-Fixed PostScript output:
- - doesn't seg fault if file is unwritable.
- - incorrect DSC comment - need colon in '%%Page:'.
- - use 'imagemask' command for masks.
- - output filters in the correct order.
- - Stream::isBinary() checks the next-to-bottom, not top, stream.
- - if page width > height, rotate it 90 degrees.
- - if page is larger than paper size, scale it down.
-Set default MediaBox to 8.5" x 11" to deal with non-compliant PDF
- files which don't specify a MediaBox.
-Added DEBUG_MEM stuff in gmem.c and gmempp.cc.
-Fixed memory leaks:
- - LTKWindow didn't delete the LTKBox.
- - LinkAction needs a virtual destructor.
-Use $(RANLIB) variable in goo/Makefile and ltk/Makefile.
-Allocate image data after calling XCreateImage, using
- image->bytes_per_line -- works in 24-bit mode now.
-DCTStream rounds width of rowBuf lines up to the next multiple of
- mcuWidth, so last MCU doesn't run off end of buffer.
-Increase size of block (from 255 to 1024 bytes) read at end of file to
- search for 'startxref'.
-Skip past garbage at start of file, look for '%PDF'.
-Moved more compiler options out of Makefiles into Makefile.config.
-Top-level Makefile uses '$(MAKE)' instead of 'make' for making
- subdirectories.
-Space/PageDown/Next and Backspace/PageUp/Previous now moves to
- next/previous page if already scrolled to bottom/top of current
- page.
-
-
-0.5a (96-jul-09)
-----------------
-[not a public release]
-For PDF 1.2 (a.k.a. Amber, a.k.a. Acrobat 3) support:
- - look for trailer after first xref instead of at end of file.
-Deal with font subsets by converting character names of the form
- 'Cnnnn' to the appropriate character from the standard encoding.
-Extract encoding from embedded Type 1 fonts.
-Kludge to fill one-pixel thick polygons.
-Changed X font encoding to use endash for hyphen (gets rid of too-long
- hyphens).
-Handle Resources key in Pages dictionaries (needed for pstoedit
- output).
-Fix comment handling in Parser (needed for pstoedit output).
-Move Bezier curve conversion from GfxState to XOutputDev; look at
- flatness parameter in GfxState.
-Change all of the path functions in XOutputDev (stroke, fill, clip) to
- use the same path transformation/conversion function.
-Rewrote PostScript output driver as a subclass of OutputDev; removed
- duplicated code (ps_ functions) from Gfx.
-Fixed bug in xref code with small (< 1024 bytes) PDF files.
-Implemented BX/EX operators.
-Added PDFDoc class.
-
-
-0.6 (96-nov-12)
----------------
-Add support for PostScript output to stdout (-) and to a command
- (|lpr); added -ps option and psFile resource.
-Decryption is implemented but not included in the distribution due to
- legal restrictions: the decryption algorithm is a trade secret of
- RSA, Inc., and the U.S.A. still has bogus export controls on
- cryptography software.
-Added .xpdfrc config file:
- - Added fontmap parameter: user can map PDF font names to X fonts.
- - Added fontpath parameter: search for Type 1 font if encoding is
- not in PDF file.
-Incremental display: display is updated after every 200 commands.
-Added forward and backward by-10-page buttons.
-Links:
- - Implement links with "Launch" actions that point to PDF files.
- - Draw borders around links.
- - Handle links with named destinations.
- - GoToR links specify a page number instead of a page reference.
-Optimizations:
- - Rewrote Stream to use buffering, and added lookChar() functions;
- rewrote Lexer to take advantage of this.
- - Use hash tables for name->code mapping in font encodings.
- - Made XOutputDev::doCurve() iterative, changed /2 to *0.5, and
- changed the flatness test.
-Added file name to window title.
-Implemented RunLength filter.
-Implemented forms.
-Convert ObjType to an enum.
-Changed isDict("Pages") to isDict() (in Catalog.cc) to deal with
- incorrect PDF files.
-Changed color selection so that very pale colors don't map to white.
-Fixed bug in CCITTFax filter (multiple make-up codes).
-In GString::clear(): need to set length to 0 before calling resize().
-Base initial window size on first displayed page, not page 1; deal
- correctly with rotated pages.
-Added ltkGetIntResource() and LTKApp::getIntResource().
-PostScript output fixes:
- - Escape backslashes in strings.
- - When doing ASCII85 encoding, keep both chars of EOF marker ('~>')
- on same line.
- - Add extra line '%-EOD-' after image data streams; call wrapper
- functions for image and imagemask which look for this line -- this
- should fix the 'too much data in stream' bug.
- - Font tags can be reused for different fonts on different pages --
- so use font object reference (number/generation) instead.
-Initialize character widths to zero (this caused crashes on OSF/1).
-Handle image masks which go outside of pixmap.
-Makefile.config changes:
- - Remove -o in C++ compile rule.
- - Add $(AR) variable.
-Code which read char widths from font dictionary read all but the last
- width.
-Add 'return 0;' to main() in xpdf and pdftops.
-Allow fonts to use StandardEncoding.
-Convert man pages to VMS help files.
-
-0.7 (97-may-28)
----------------
-Implemented FlateDecode filter (for PDF 1.2).
-Basic xref table reconstruction for damaged files
-New pdftotext program converts PDF to plain text.
-Implemented menus in LTK; added a menu to xpdf.
-Added open and save functions; allow xpdf to start without any PDF
- file.
-Implemented text find.
-Implemented text select/copy.
-Change mouse cursor when it's over a link.
-Embed Type 1 fonts in PostScript output.
-Moved rotate functions to menu; added quit to menu.
-Fixed stroke color bug in PostScript output (was using fill color
- instead of stroke color; this sometimes caused lines to be missing
- (white) in PostScript output).
-Support Launch-type links -- pops up a dialog before executing
- anything. Expects the A (action) dictionary to contain a Unix
- dictionary with F (file) and P (paremeter) keys just like the Win
- dictionary.
-A moveto op all by itself should just be discarded, instead of
- generating a subpath with one point (this was causing seg faults).
-Balanced parentheses in strings don't need to be escaped.
-Tj operator in PostScript prolog didn't check for zero when dividing
- by length of string.
-Implemented selection in LTK; TextIn widgets support dragging/copy/
- paste.
-Handle font subsets that use hex character codes.
-Added icon pixmap; added the XPMLIB and NO_XPM variables to
- Makefile.config.
-Fixed subtle bug in use of horizontal scaling parameter (it affects
- only the width of drawn characters, not positioning done in text
- space).
-Memory testing (with DEBUG_MEM):
- - gmalloc now fills memory blocks with garbage to catch unitialized
- fields.
- - gfree fills memory blocks with garbage to catch uses of freed
- blocks.
-Handle image masks which go off the pixmap on the top and/or left.
-Fixed inline functions which had two return statements (to make the
- HP, SCO, and other cfront-based compilers happy).
-Fixed bug which caused seg faults when following a link to a different
- file (info in LinkGoto object was used after link was deleted by
- loadFile).
-If page content is an array of streams, the streams are concatenated;
- objects and commands can span multiple streams.
-If file open fails, try lower-casing and upper-casing the file name.
-Commands should end when lexer sees a '/' character.
-GString::append(char *, int) was broken.
-Changed LTKScrollingCanvas redraw to be more efficient: copy as much
- as possible from window before copying from off-screen pixmap.
-Ignore gs (set extended graphics state) operator.
-Handle colorspaces (CalGray/RGB are treated as DeviceGray/RGB; the
- weird colorspaces are not yet implemented).
-Named destinations (for links) can be strings as well as names; deal
- with the names tree in the catalog.
-Clip to the page CropBox.
-Added '-q' to gzip options (to suppress warnings, in case user has -v
- in GZIP env var).
-Added 'include Makefile.config' to top-level Makefile.
-Added INSTALL variable to Makefile.config; used in top-level
- Makefile.
-Always initialize LinkDest left/bottom/top/right/zoom fields (bogus
- floating point values were causing crashes on Alpha).
-Added Makefile.config options for Digital Unix (DEC compilers), HP-UX
- (HP compilers), SCO Unix, and Evans & Sutherland ES/OS.
-Added flag to set stream mode in fopen call for VMS.
-Rewrote Link module.
-Pages with no contents shouldn't cause an error message.
-In PostScript output: pdfImM needs to set fill color before doing
- imagemask.
-If font doesn't specify character widths, use widths from built-in
- font, based on font flags.
-Fixed LTK scrollbar to delay before repeating and to control the
- period between repeats.
-Removed window/widget copy() methods (they were untested and unused).
-Unknown filter types produce a single error message instead of a
- stream of errors.
-Added a dummy target in top-level Makefile so making individual
- executables (e.g., 'make pdftops') should now work.
-Added optional xpdf-flip.ltk with buttons on right side instead of
- bottom of window.
-
-0.7a (98-feb-22)
-----------------
-Moved find command from menu to toolbar button ('f' key still works).
-Support TrueColor visuals.
-Added a -cmap option and a installCmap resource to install a private
- colormap.
-Mouse button 2 pans the window.
-Selecting a URI link now executes a configurable command (from the
- urlCommand resource).
-Added a "link info" display which shows the URL or file for the link
- under the mouse.
-Don't draw (or convert to PostScript) text drawn in render modes 3 and
- 7 -- this is invisible text, used by Acrobat Capture; this text is
- still passed to the TextPage object so that selection works.
-Recognize (and quietly ignore) marked content operators (BMC, BDC,
- EMC, MP, DP).
-Recognize new color-setting operators (scn, SCN).
-Added A4_PAPER option.
-Embed external Type 1 font files (this currently only works with PFA
- files).
-Added "-level1" option (in xpdf and pdftops) to generate Level 1
- PostScript.
-Setup autoconf -- replaced Makefile.config. Added SELECT_TAKES_INT
- flag, and use configure to autodetect (for HP-UX).
-Fixed appendToPath() to behave reasonably when appending ".." to root
- directory.
-Fixed array size in FlateStream::compHuffmanCodes() (was causing xpdf
- to crash under OSF/1).
-ASCII85Stream, ASCIIHexStream, and DCTStream didn't check for EOF and
- could run past the end of the stream in damaged files.
-Handle hex escapes (#xx) in names. Still allow the name /# for
- backward-compatibility.
-Check for NULL characters in encoding array in GfxFont.cc (was calling
- strcmp() with NULL which crashed under Solaris).
-PageAttrs::PageAttrs() didn't initialize crop box boundaries.
-Changed uses of lookup() to lookupNF() in XRef.cc.
-Fixed type checking of operators which take a variable number of
- args.
-Gfx::buildImageStream() doesn't need to check for parser (since I got
- rid of the bogus array-of-command thing).
-XOutputFont matches on font reference instead of font tag (similar to
- PSOutputDev fix).
-Fixed bug in position calculation for multi-char substitutions in
- XOutputDev.
-Cleaned up local variables which hid class variables.

- problem where XQueryTree crashed if the window no longer existed
- (with leftover events from a destroyed window). (Thanks to Yair
- Lenga for the suggestion.)
-Create a new GC for selection -- xor black and white (instead of LTK
- foreground and background).
-Fixed crash with blank lines in .xpdfrc.

- entries.
-Added NO_TEXT_SELECT option.
-Ignore APPn/COM/etc. markers in DCT streams.

- windows/dialogs are simply closed.
-Optimized DCT decoder; switched to integer arithmetic.
-The "/Type /Annots" field in an annotation dictionary is optional.
-Check for null nameTree in Catalog::findDest().
-In XOutputDev, search user font map before default font map.

-Added a hack which allows better font substitution for some Type 3
- fonts. Also allow character names of the form /nn and /nnn.
-Added <strings.h> and <bstring.h> to LTKApp.cc (needed by AIX and IRIX
- for bzero() declaration for FD_ZERO).
-

- - Added better test for sys/select.h, sys/bsdtypes.h, strings.h,
- bstring.h.
- - New VMS make scripts from Martin P.J. Zinser.

- (which isn't supported by all make implementations). Also changed
- all non-system include files to '#include "..."' (from '<...>').
-Tweaked the TextOutputDev heuristics slightly.
-Modify Gfx to use a stack of resources -- this is necessary for Form

-Added PDFDoc::isLinearized() and corresponding code in pdfinfo.cc.
-Handle files with an incorrect page count in the Pages dictionary
- (FOP, from the Apache project produces a page count of 0).

-FlateStream didn't correctly handle zero-length streams.
-Xref reconstruction didn't handle the case where the opening "<<"
- immediately followed "trailer" with no intervening whitespace.

-Fixed a bug in the new image transformation code.
-Look for character names of the form "<letter><digit><digit>", instead
- of looking for names beginning with a few specific letters.

- invalid type (i.e., not an array), don't draw the link at all (this
- matches Adobe's behavior).
-Don't remap small caps and oldstyle glyphs in the name-to-Unicode
- table - it messes up TrueType font encodings.

- in tables) were being split vertically onto multiple lines.
-Automatically select the correct radio button ("print with command"
- vs. "print to file") in the print dialog.

-Encryption with revision=2 always uses a 40-bit key, regardless of the
- specified Length value.
-Yet another minor change to the TrueType font encoding deciphering
- algorithm.
-Don't completely invalidate the Catalog if one (or more) of the page
- objects are bogus -- just skip over those pages.
-Removed the workaround in pdftops for too-small Length2 values in Type
- 1 fonts -- it was causing problems on various PostScript printers.

- near complete yet).
-Extended the "unicodeToUnicode" config option to also apply to CID
- fonts.
-Added the narrow Latin characters to the Adobe-Korea1.cidToUnicode
- file in the Korean language support package.
-Fixed the code that handles page rotation in PSOutputDev.

-3.02 (2007-feb-27)
-------------------
-Added anti-aliasing for vector graphics; added the vectorAntialias
- xpdfrc option; added the "-aaVector" switch to xpdf and pdftoppm.
-Implemented stroke adjustment (always enabled by default, ignoring the
- SA parameter, to match Adobe's behavior), and added the strokeAdjust
- xpdfrc command.
-Support PDF 1.6 and PDF 1.7.
-Added support for AES decryption.
-Added support for OpenType fonts (only tested with 8-bit CFF data so
- far).
-Added user-configurable key/mouse bindings - the bind/unbind xpdfrc
- commands.
-Cleaned up the full-screen mode code and added the ability to toggle
- it on the fly (the default key binding is alt-f).

- (grayscale) DCT images, in addition to 3-component (RGB) images.
-Fixed bugs in handling sampled (type 0) functions with 32-bit
- samples.
-Fixed some things to support DeviceN color spaces with up to 32
- colorants.
-Pdftops now constructs the %%Creator and %%Title DSC comments from the
- relevant information in the PDF Info dictionary.
-Tweak the TrueType font encoding deciphering algorithm.
-Added the "mapUnkownCharNames" xpdfrc option.
-Fix a bug (that only showed up with certain window managers) in the
- intermediate resize event optimization. [Thanks to Michael Rogers.]

- crash).
-Added support for transfer functions in PostScript output.
-Be a bit more tolerant of Link destinations that contain null values
- for positioning parameters.
-Use ordered dot dithering instead of clustered dot dithering at
- resolutions below 300 dpi (for monochrome output).
-Fixed security holes (bounds checking issues) in several places.
-Don't bother creating a SplashFont (allocating memory) for fonts that
- are only used for hidden text - this avoids problems with fonts of
- unreasonably large sizes.
-Clipping in TextOutputDev was off for characters on the left edge of
- the page.
-The scn and SCN operators weren't correctly handling colors with more
- than four components.
-FoFiType1::writeEncoded wasn't always correctly finding the end of the
- encoding.
-Use the ColorTransform parameter in the DCTDecode stream dictionary.
-Type 3 fonts are allowed to have a bbox of [0 0 0 0], which means
- "unspecified" -- don't issue error messages in that case.
-Perform the transform (to device space) in Splash instead of in
- SplashOutputDev -- this is needed to correctly handle round joins
- and caps on stroked paths.
-PSOutputDev now rasterizes any pages that use transparency.
-Limit the crop, bleed, trim, and art boxes to the edges of the media
- box (per the PDF spec).
-Change GString to increase the allocation increment by powers of two.

- tiling pattern fills.
-Avoid a divide-by-zero in stitching functions which have a subfunction
- with empty bounds.
-Honor the "Hidden", "NoView", and "Print" flags on annotations.
-Rewrote the pixel rendering code in Splash to use a single set of
- pixel pipeline functions.
-Added support for transparency groups and soft masks.
-Fixed the transparency blend functions to match the addendum published
- by Adobe.
-Changed Splash/SplashBitmap to store alpha in a separate plane.
-Setting the color space now selects the correct default color for that
- color space.
-Remove the mutex lock from GlobalParams::getErrQuiet() to avoid a
- deadlock when parseCIDToUnicode() or parseUnicodeToUnicode() calls
- it from inside a locked section.
-Added error checking (on the argument count) in the sc/SC/scn/SCN
- operators.
-Skip over notdef glyphs in TrueType fonts (which sometimes get drawn
- as little boxes), to match Adobe's behavior.
-Painting operations in a Separation color space with the "None"
- colorant or a DeviceN color space with all colorants set to "None"
- never mark the page.
-Fixed an obscure bug in the JPX decoder - it wasn't reading the extra
- stuffing byte in the case where the last byte of a packet header was
- 0xff.
-Change the TrueType font parser (FoFiTrueType) to change the glyph
- count rather than report an error if the 'loca' table is too small.
-Fixed a couple of bugs in the JBIG2 decoder.
-Added stochastic clustered dot dithering.
-Added the screenType, screenSize, screenDotRadius, screenGamma,
- screenBlackThreshold, and screenWhiteThreshold xpdfrc settings.
-PSOutputDev now correctly handles invalid Type 3 charprocs which don't
- start with a d0 or d1 operator
-FreeType 2.2.x support - get rid of the FT_INTERNAL_OBJECTS_H include,
- and add some 'const' declarations.

- when looking for objects.
-Added the "-exec" switch to xpdf.
-Removed the xpdf.viKeys X resource.
-Changed the color key / explicit masked image code in PSOutputDev to
- generate better PS code, including a Level 3 option.
-Tweaked the DEBUG_MEM code for performance.
-Move the JBIG2 global stream reading code into reset() instead of the
- constructor - this way, pdftotext doesn't end up reading the global
- stream.
-Added the "-preload" option to pdftops and the psPreload xpdfrc
- command.
-Added the "zoom to selection" command (on the popup menu).
-Fix a bug (in xpdf/pdftoppm/pdftops) with tiling patterns whose bbox
- size is different from their xStep/yStep.
-Implemented stroke with pattern color spaces.
-Following a link to a page whose CropBox was different from the
- MediaBox was resulting in an incorrect scroll position.
-Parse truncated date strings from the Info dictionary correctly.
-Change FoFiType1 to handle Type 1 fonts with two /Encoding keys.
-Extend the PSOutputDev shaded fill code to handle DeviceCMYK shaded
- fills in level2sep and level3sep modes.
-Detect infinite loops in the Page tree.
-Optimized the ASCII85Encoder code.
-Tweaked the text extractor to do a better job of lining up rows of
- text.
-Leave images compressed (or re-compress them with RLE) in PostScript
- output when setting up images for forms and Type 3 fonts (or with
- -preload).
-Extend FoFiType1 to handle Type 1 fonts with octal character codes in
- their encodings.
-Use a custom string formatter to avoid problems with locale-based decimal
- formatting (commas instead of periods) in PS output.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, 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 show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 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 Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program 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. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-Xpdf
-====
-
-version 3.02
-2007-feb-27
-
-The Xpdf software and documentation are
-copyright 1996-2007 Glyph & Cog, LLC.

-Email: derekn@foolabs.com
-WWW: http://www.foolabs.com/xpdf/

-
-Compiling xpdf
---------------
-
-Xpdf is written in C++ (with a little bit of C). It should work with
-any ANSI-compliant C++ and C compilers. The systems and compilers
-it's been tested with are listed on the xpdf web page.
-
-Xpdf requires the Motif (or Lesstif) toolkit.
-
-The following notes give specific instructions for compiling on
-different systems.
-
-
-**************
-*** UNIX ***
-**************
-
-* Install t1lib (if desired). The resulting library (libt1) and
- include files (t1lib.h and t1libx.h) should be placed somewhere on
- the standard search paths. Alternatively, when you configure xpdf,
- you can use the following options to tell configure where to find
- the t1lib files:
-
- --with-t1-library=PATH
- --with-t1-includes=PATH
-
-* Install FreeType 2 (this is required). WARNING: You must have
- version 2.0.5 or newer. Some older versions of XFree86 ship with an
- older version of FreeType, which means you'll need to explicitly set
- include and library paths to get the correct version:
-
- --with-freetype2-library=PATH
- --with-freetype2-includes=PATH
-
- (The include path is the directory which contains the freetype2
- directory, i.e., do NOT include "freetype2" in the
- --with-freetype2-includes path. For example, with the default
- installation, the library path is /usr/local/lib and the include
- path is /usr/local/include/freetype2.)
-
-* If you have Motif (or Lesstif) installed in a non-standard place,
- you can use the following options to tell configure where to find
- it:
-
- --with-Xm-library=PATH
- --with-Xm-includes=PATH
-
-* Run the configure script:
-
- ./configure
-
- This should produce a set of makefiles customized for your system.
- The configure script accepts the following options (in addition to
- the usual things accepted by autoconf configure scripts):
-
- --prefix=PREFIX
- Changes the directory where xpdf is installed. The default is
- /usr/local.
-
- --enable-a4-paper
- Switches the default paper size for PostScript output (xpdf
- and pdftops) to A4. The default is Letter size.
-
- --enable-no-text-select
- With this option, xpdf will not copy text. (This is only
- useful on closed systems where the user can't get at the PDF
- file directly.)
-
- --enable-opi
- Enables support for generation of OPI (Open Prepress
- Interface) comments with pdftops.
-
- --sysconfdir=DIR
- Look for the system-wide xpdfrc config file in this directory.
- The default is PREFIX/etc.
-
- --with-appdef-dir=DIR
- Use the specified app-defaults directory. The default is
- /usr/lib/X11/app-defaults.
-
- If you need to pass specific options to the C and/or C++ compiler,
- you can set the CFLAGS and/or CXXFLAGS environment variables before
- running the configure script. Any options given that way will be
- added to the CFLAGS/CXXFLAGS used by all of the Xpdf makefiles.
-
-* Type 'make'. This should build the executables:
-
- xpdf/xpdf
- xpdf/pdftops
- xpdf/pdftotext
- xpdf/pdfinfo
- xpdf/pdffonts
- xpdf/pdftoppm
- xpdf/pdfimages
-
-* If desired, type 'make install' to install the binaries and man
- pages.
-
-The old Makefile.config and Makefiles are no longer provided or
-supported. If you really want to manually configure Xpdf (which is
-not recommended), the files that need to be created are aconf.h,
-Makefile, goo/Makefile, fofi/Makefile, splash/Makefile, and
-xpdf/Makefile, all of which are generated from the corresponding '.in'
-files.
-
-If you want to run a quick test, there is a tiny PDF file included
-with xpdf, as misc/hello.pdf .
-
-
-*************
-*** VMS ***
-*************
-
-* The 'stddef.h' include file which comes with older versions of gcc
- may be missing a definition for wchar_t. In this case, add the
- following lines:
- -----
- File GNU_CC:[INCLUDE]STDDEF.H;2
- 44 /* Wide characters, not yet supported by VAXCRTL [match VAXC's <stddef.
- 45 #if !defined(_WCHAR_T) && !defined(_WCHAR_T_)
- 46 typedef unsigned int wchar_t;
- 47 #endif
- 48 #define _WCHAR_T
- 49 #define _WCHAR_T_
- 50
- -----
-
-* Read the instructions at the top of vms_make.com.
-
-* Type '@vms_make' in the top-level directory. You'll probably want
- to use some of the options described in the file.
-
-* The executables will be left in '[.xpdf]'.
-
-If you want to run a quick test, there is a tiny PDF file included
-with xpdf, as misc/hello.pdf .
-
-
-**************
-*** OS/2 ***
-**************
-
-Xpdf is known to run under OS/2 with the EMX runtime environment and
-XFree86. Using a proper autoconf port you can generate a valid
-configure script version.
-
-
-***************
-*** Win32 ***
-***************
-
-The non-X programs (pdftops, pdftotext, pdfinfo, pdffonts, pdfimages,
-and pdftoppm) will compile with both gcc (from cygwin), djgpp (the
-Delorie port of gcc) and Microsoft Visual C++.
-
-With cygwin, the build procedure is the same as for Unix:
-
- * Open a shell.
-
- * ./configure
-
- * make
-
- * make install
-
-It is also possible to build the Xpdf viewer with the cygwin XFree86
-port (thanks to Michael A. Richmond for these instructions):
-
- * make sure you have the lesstif, XFree86-base, and XFree86-prog
- cygwin packages installed (all from the "XFree86" category)
-
- * to build t1lib:
- - cd T1Lib-x.y
- - ./configure --without-x
- - make without_doc
- - make install
- (this should install /usr/local/include/t1lib.h and
- /usr/local/lib/libt1.a)
-
- * to build xpdf:
- - cd xpdf-x.yy
- - ./configure --with-t1-library=/usr/local/lib
- --with-t1-includes=/usr/local/include
- --with-freetype2-library=/usr/X11R6/lib
- --with-freetype2-includes=/usr/X11R6/include/freetype2
- --with-Xm-library=/usr/X11R6/lib
- --with-Xm-includes=/usr/X11R6/include
- (all on one line)
- - make
- (this should build xpdf.exe, in addition to the command line
- utilities)
-
-With djgpp:
-
- * Open a DOS window.
-
- * ./dj_make
-
- * djgpp is a DOS/Windows port of gcc, available from
- http://www.delorie.com/
-
-With djgpp, for DOS 6 (instead of Win32):
-
- * ./dj_make
-
- * cd xpdf
-
- * strip pdftops.exe
-
- * exe2coff pdftops.exe
-
- * copy /B c:\djgpp\bin\cwsdstub.exe+pdftops pdftops.exe
-
- * upx pdftops.exe
- - if you want compressed executables
-
- * and similarly for the other executables
-
- * cwsdstub.exe comes from djgpp/v2misc/csdpmi5b.zip on any of the
- djgpp ftp mirrors; exe2coff is part of the standard djgpp install
-
- * upx comes from http://upx.sourceforge.net/
-
-With the Microsoft tools:
-
- * Open a DOS window.
-
- * Type "cl". If you get the message "Bad command or file name", you
- must run VCVARS32.BAT. (The location of this BAT file can be
- determined with Explorer.)
-
- * Type "ms_make"
-
-The dj_make and ms_make scripts don't build pdftoppm -- you'll need to
-install t1lib and FreeType 2 before you can compile pdftoppm.

-Xpdf
-====
-
-version 3.02
-2007-feb-27
-
-The Xpdf software and documentation are
-copyright 1996-2007 Glyph & Cog, LLC.
-
-Email: derekn@foolabs.com
-WWW: http://www.foolabs.com/xpdf/
-
-The PDF data structures, operators, and specification are
-copyright 1985-2006 Adobe Systems Inc.
-
-
-What is Xpdf?
--------------
-
-Xpdf is an open source viewer for Portable Document Format (PDF)
-files. (These are also sometimes also called 'Acrobat' files, from
-the name of Adobe's PDF software.) The Xpdf project also includes a
-PDF text extractor, PDF-to-PostScript converter, and various other
-utilities.
-
-Xpdf runs under the X Window System on UNIX, VMS, and OS/2. The non-X
-components (pdftops, pdftotext, etc.) also run on Win32 systems and
-should run on pretty much any system with a decent C++ compiler.
-
-Xpdf is designed to be small and efficient. It can use Type 1 or
-TrueType fonts.
-
-
-Distribution
-------------
-
-Xpdf is licensed under the GNU General Public License (GPL), version
-2. In my opinion, the GPL is a convoluted, confusing, ambiguous mess.
-But it's also pervasive, and I'm sick of arguing. And even if it is
-confusing, the basic idea is good.
-
-In order to cut down on the confusion a little bit, here are some
-informal clarifications:
-
-- I don't mind if you redistribute Xpdf in source and/or binary form,
- as long as you include all of the documentation: README, man pages
- (or help files), and COPYING. (Note that the README file contains a
- pointer to a web page with the source code.)
-
-- Selling a CD-ROM that contains Xpdf is fine with me, as long as it
- includes the documentation. I wouldn't mind receiving a sample
- copy, but it's not necessary.
-
-- If you make useful changes to Xpdf, please make the source code
- available -- post it on a web site, email it to me, whatever.
-
-If you're interested in commercial licensing, please see the Glyph &
-Cog web site:
-
- http://www.glyphandcog.com/
-
-
-Compatibility
--------------
-
-Xpdf is developed and tested on a Linux 2.4 x86 system.
-
-In addition, it has been compiled by others on Solaris, AIX, HP-UX,
-Digital Unix, Irix, and numerous other Unix implementations, as well
-as VMS and OS/2. It should work on pretty much any system which runs
-X11 and has Unix-like libraries. You'll need ANSI C++ and C compilers
-to compile it.
-
-The non-X components of Xpdf (pdftops, pdftotext, pdfinfo, pdffonts,
-pdftoppm, and pdfimages) can also be compiled on Win32 systems. See
-the Xpdf web page for details.
-
-If you compile Xpdf for a system not listed on the web page, please
-let me know. If you're willing to make your binary available by ftp
-or on the web, I'll be happy to add a link from the Xpdf web page. I
-have decided not to host any binaries I didn't compile myself (for
-disk space and support reasons).
-
-If you can't get Xpdf to compile on your system, send me email and
-I'll try to help.
-
-Xpdf has been ported to the Acorn, Amiga, BeOS, and EPOC. See the
-Xpdf web page for links.
-
-
-Getting Xpdf
-------------
-
-The latest version is available from:
-
- http://www.foolabs.com/xpdf/
-
-or:
-
- ftp://ftp.foolabs.com/pub/xpdf/
-
-Source code and several precompiled executables are available.
-
-Announcements of new versions are posted to several newsgroups
-(comp.text.pdf, comp.os.linux.announce, and others) and emailed to a
-list of people. If you'd like to receive email notification of new
-versions, just let me know.
-
-
-Running Xpdf
-------------
-
-To run xpdf, simply type:
-
- xpdf file.pdf
-
-To generate a PostScript file, hit the "print" button in xpdf, or run
-pdftops:
-
- pdftops file.pdf
-
-To generate a plain text file, run pdftotext:
-
- pdftotext file.pdf
-
-There are four additional utilities (which are fully described in
-their man pages):
-
- pdfinfo -- dumps a PDF file's Info dictionary (plus some other
- useful information)
- pdffonts -- lists the fonts used in a PDF file along with various
- information for each font
- pdftoppm -- converts a PDF file to a series of PPM/PGM/PBM-format
- bitmaps
- pdfimages -- extracts the images from a PDF file
-
-Command line options and many other details are described in the man
-pages (xpdf.1, etc.) and the VMS help files (xpdf.hlp, etc.).
-
-
-Upgrading from Xpdf 2.xx
-------------------------
-
-WARNING: Xpdf 3.00 switched to a new PDF rasterizer, which no longer
-uses X fonts. You'll need a set of Base-14 fonts -- the URW fonts
-distributed with ghostscript can be used for this. Xpdf will search
-for the URW fonts, but if you have them installed in a non-standard
-directory, you'll need to set up an xpdfrc config file to point to
-them. For full details, please see the xpdfrc(5) man page.
-
-
-Compiling Xpdf
---------------
-
-See the separate file, INSTALL.
-
-
-Bugs
-----
-
-If you find a bug in Xpdf, i.e., if it prints an error message,
-crashes, or incorrectly displays a document, and you don't see that
-bug listed here, please send me email, with a pointer (URL, ftp site,
-etc.) to the PDF file.

-\`configure' configures this package to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:

-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags

- CXX C++ compiler command
- CXXFLAGS C++ compiler flags

-// Terminology
-// -----------
-//
-// character code = number used as an element of a text string
-//
-// character name = glyph name = name for a particular glyph within a
-// font
-//
-// glyph index = GID = position (within some internal table in the font)
-// where the instructions to draw a particular glyph are
-// stored
-//
-// Type 1 fonts
-// ------------
-//
-// Type 1 fonts contain:
-//
-// Encoding: array of glyph names, maps char codes to glyph names
-//
-// Encoding[charCode] = charName
-//
-// CharStrings: dictionary of instructions, keyed by character names,
-// maps character name to glyph data
-//
-// CharStrings[charName] = glyphData
-//
-// TrueType fonts
-// --------------
-//
-// TrueType fonts contain:
-//
-// 'cmap' table: mapping from character code to glyph index; there may
-// be multiple cmaps in a TrueType font
-//
-// cmap[charCode] = gid
-//
-// 'post' table: mapping from glyph index to glyph name
-//
-// post[gid] = glyphName
-//
-// Type 42 fonts
-// -------------
-//
-// Type 42 fonts contain:
-//
-// Encoding: array of glyph names, maps char codes to glyph names
-//
-// Encoding[charCode] = charName
-//
-// CharStrings: dictionary of glyph indexes, keyed by character names,
-// maps character name to glyph index
