Programs that already use - t1lib have to be rewritten (sorry....) - - -- Function for computing the width of a string added (T1_GetStringWidth()). - - -- Function for computing the BoundingBox of a string added - (T1_GetStringBBox()). - - -- Function T1_GetMetricsInfo() added. It returns a struct containing width, - bounding box, number of characters and horizontal position of the characters - in character space coordinates (afm-units). - - -- Function T1_GetBBox() renamed to T1_GetCharBBox() for consistency reasons. - - -- All exit() calls removed from library and replaced by appropriate error - return codes. - - -- t1lib now optionally supports a logfile for logging of error- and - warning-messages at runtime. The "verbosity" of this logfile may be chosen - by the user. - - -- Documentation more complete. - - - -July 1997: t1lib-0.3-beta -------------------------- - - -- Code for placing character bitmaps in T1_SetString() slightly advanced; the - restrictions concerning slanted fonts are eliminated. - - -- T1_GetStringBBox()/T1_GetCharBBox() extended. It is now possible to get the - bounding box if the font is slanted. This is implemented by examining the - characters outline at 1000bp. - - -- Some Bugs in the code managing linked lists of font sizes have been - corrected. - - -- Bug in T1_CopyFont() has been corrected. This should work now. - - -- The behavior during configuration file searching has been changed to - be compatible to well known UNIX-conventions. - - -- As the main new feature in this release t1lib now has direct support - for X11 (optionally). There is a set of functions that act similar - to XDrawText(), i.e. they draw directly into a drawable (pixmap or - window). - - - Caching of bitmaps of the X11 rastering functions is also done - in the X-Server for maximum performance (although it is not as - fast as I dreamed of, admittedly). - - - X11 rastering functions use the current foreground/background - colors - - - The X11 rastering functions implement automatical antialiasing - between foreground and background color - - - The X11 rastering functions provide an opaque and a transparent - mode - - - The X11 rastering functions can draw into drawable of any depth - (provided the depth is large enough) - - -- A new target has been added to the makefiles allowing to remove - a t1lib-installation automatically from a system. - - - -December 1997: t1lib-0.4-beta ------------------------------ - - -- Many memory allocation bugs fixed. t1lib is now "libefence-proved". - - -- Kerning and Metrics-Lookup rewritten. The corresponding functions are now - based on character indices rather than on character names which makes them - up to 8 x faster than before, depeding on data and context. - - -- Raph Levien (raph@acm.org) contributed a fast algorithm for subsampling - which improves Antialiasing time significantly. - - -- Fred L. Drake, Jr. (fdrake@acm.org) contributed a Python-interface - to t1lib. This allows Python programmers to make use of Adobe Type - 1 fonts. This package, called t1python, is distributed with t1lib in - an independent subdirectory of the distribution. See README.t1python - for more information on t1python. - - -- Bitmaps and antialiased bitmaps may now be padded 8, 16 or 32 bits. This - allows (with some restrictions) somewhat faster concatenation of - characterbitmaps to stringbitmaps. The padding-value may be set and queried - at runtime. - - -- The optional X11-interface, introduced in t1lib-0.3-beta, has been reduced - to a simple wrapper. X11-pixmap caching has been completely dropped since it - has proven to be too inefficient. However, at the level of the function - calls, nothing has changed. - - -- Configuration of t1lib (with or without X11-interface) may be queried by - applicationprogrammers at compiletime or by applications at runtime. - - -- Two functions for informations on fonts have been added: - - 1) T1_GetFontBBox(): Return a fonts' bounding box. - - 2) T1_GetAllCharNames(): Return a list of all character defined in a Type 1 - font. This might be of interest if somebody wants - to set up new encodings. - - -- Function T1_CloseLib() added. This function allows to completely free the - data-structures of t1lib. T1_CloseLib() should be called in future when an - application using t1lib exits. - - -- Many other things not worth to be metioned ... - - - -March 1998: t1lib-0.5-beta --------------------------- - - -- Changed the license to the GNU General Public Library License (LGPL) - - -- Definition of INFINITY removed from - lib/type1/[regions.c|regions.h|t1imager.h]. Collided with a - definition in math.h on OS/2. - - -- Implemented proper handling of environment variables CFLAGS, LDFLAGS - and CC during build process. - - -- Added target 'without_doc' for people who have a very rudimentary or - no LaTeX-System at all - - -- Fixed some bugs that appeared when font files from database were not - found - - -- Clipmask Bug in the X11-rastering functions fixed - - -- Bugs in VM-reallocation (T1_LoadFont()) repeatedly fixed. It is now - ANSI-C compliant. - - -- Alignment of VM changed. This was needed on some systems. - - -- Set of functions for accessing information from FontInfo dictionary - is now complete. This introduces the new functions - T1_GetFullName(), T1_GetFamilyName(), T1_GetWeight(), - T1_GetItalicAngle(), T1_GetIsFixedPitch(), T1_GetVersion(), - T1_GetNotice(). - - -- ATTENTION: In the above context, T1_GetPostScriptName() has been - renamed to T1_GetFontName() for consistency reasons, sorry. - - -- ATTENTION: All types "unsigned char (*)" have been changed to - char (*) in the API functions. This was necessary while adapting - t1lib to ANSI-standard to make it portable. Sorry for this - confusion. - - -- New function T1_AddFont(): Fonts can now be added to the font - database at runtime. This means especially, one can ignore a - FontDataBase file thus can start t1lib-programs on single fontfiles - without doing a complete setup before. - - -- There is now also the possibility to ignore the currently active - configuration file, thereby setting all search paths to the current - working directory and having an empty font data base. This is meant - for small applications that work on single files. - - -- t1lib is now able to work with fonts without corresponding - afm-files. AFM-information can be produced from pfa- and - pfb-files. This, of course, refers only to character-metrics - information. - - -- A function T1_WriteAFMFallbackFile() is provided which allows to - dump metrics information to a valid AFM-file. - - -- New subdirectory type1afm created which contains type1afm, a program - to extract afm files from Type 1 font files. - - -- Renamed definitions MAX, MIN, ABS, TRUE and FALSE because they - collided with system header files on some systems. - - -- Corrected antialiasing functions. The metrics should now be as - correct as possible and black pixel at the right edge of the bitmaps - should not appear any more. - - -- Handling of unencoded characters in strings (such as adieresis in - AdobeStandardEncoding) is now consistent in rotated and non-rotated - glyphs. - - -- A few functions have been added to get information on the file search - environment and to manipulate the search paths from within applications. - - -- Mixed endian setups (i.e., client and X-server on different machines - with different endianess) should now be handled correctly. - - -- In summary t1lib should now be much more portable than before. - - -- Update to t1python-0.3 - - - -March 1998: t1lib-0.6-beta --------------------------- - - -- Cleaned up the sources in type1-directory - - -- Functions Xalloc() and Xfree removed. x11dummy.c from list of source files - removed. - - -- A few bugs fixed - - -- Character positioning rewritten. It does now handle strings - correctly in which the leftmost pixels does not belong to the first - character and the rightmost pixels do not belong to the last character. - - -- t1lib now substitutes .notdef for defined character names that have - no corresponding charstring. This is a workaround for some fonts in - the ghostscript distribution (e.g., s050000l.pfb) - - -- Separated the X11-wrapper from the rest of t1-stuff. t1lib now - consists of two libraries and two include files. - - -- Cleaned up configuration and compilation process. - - - -May 1998: t1lib-0.7-beta ------------------------- - - -- Athena libraries are explicitly located for non-standard system - - -- glyph-structure changed. glyph.metrics.characterWidth is replaced - glyph.metrics.advanceX and an entry glyph.metrics.advanceY is added. - - -- Interpretation of the sign of glyph.metrics.descent has changed. - - -- String-rastering functions now support Underlining, Overlining and - Overstriking. - - -- Functions for overriding default line-parameters implemented. - - -- Whitespace at beginning and ending of glyphs is now correctly recorded into - leftSideBearing and RightSideBearing. - - -- Function T1_ConcatGlyphs() added to API. It concatenates two glyphs of - identical depth with an optional displacement inserted. - - -- xglyph output window has changed for X-rastering functions. It is now of - constant size with the logical origin in the center. Too large glyphs are - simply clipped. - - -- t1lib can be compiled and run on VMS thanks to John Hasstedt - (John.Hasstedt@sunysb.edu). A configure.com script for building on VMS is - included in the toplevel directory. - - -- T1_GetMetricsInfo() and T1_GetStringBBox() fixed. Now results are correct - also if the leftmost pixel in a glyph doesn't belong to the first char and if - the rightmost pixel does not belong to the last character. - - -- Leading and trailing white space in glyphs should now be recorded - consistently and correctly for all rastering functions. - - -- xglyph can now display a character map of a font. - - -- Global variable T1_errno introduced. It basically works the same way - as the errno in libc. This allows applications a unified - error-handling. - - -- Update to t1python-0.7. - - - -November 1998: t1lib-0.8-beta ------------------------------ - - -- T1_GetAllCharNames() returned invalid list if the Charstrings dictionary was - larger than the actual number of charstrings defined (which is perfectly - valid, even if it does not make much sense) --> fixed. - - -- 4 x Antialiasing implemented. This can improve the quality at small sizes - once more, at the cost of some computational and memory requirement. It is - possible to work with 2 x and 4 x concurrently. - - -- Function T1_GetLibIdent() added to API. - - -- Function T1_SetRasterFlags() added to API. It allows to selectively enable - or disable certain rasterizer features like, e.g., hinting. - - -- xglyph extended to support 4 x antialiasing. - - -- xglyph now recognizes a few commandline options, primarily intended for - debugging purposes. - - -- xglyph is now somewhat more intelligent (and faster) if slanting, - extending or reencoding is applied to a font. - - -- New function T1_SetDefaultEncoding(). It allows to set a default - encoding vector which then is applied to all subsequently loaded fonts - that have StandardEncoding. - - -- Bug in Type 1 rasterizer corrected which prevented fonts with non-standard - lenIV values from being correctly decrypted (Charstring decryption). - - -- Internal ISOLatin1Encoding removed from rasterizer since there's no reason - for mainting this encoding scheme internally - - -- tlib now has notion of "Encoding Schemes". The format of encoding files is - extended correspondingly and is backward compatible. - - -- Memory leaks eliminated, thanks to David Huggins-Daines. - - -- Some slight performance improvements. - - -- Kerning performance improved. Moreover, kerning pairs need no longer be - alphabetically sorted. - - -- AFM-parser modified to work with DOS-style AFM-files. - - -- Some bugs in scan-code of Type 1 rasterizer corrected. Scanner is now aware - of pfb-blocks and can scan files with multiple binary data segments. - - -- t1lib now uses GNU-libtool, thanks to Hirotsugo Kakugawa - (h.kakugawa@computer.org) - - -- An encoding file for IsoLatin2 charset is included thanks to Jiri - Pavlovsky (jirap@bajt.cz). - - -- The angle-argument of the rastering functions has been replaced by a more - general transformation specification. This is an incompatible change to - previous versions, but I think it should be worth it. - - -- t1lib can now handle fontfile names with arbitrary extensions and - even without extension. - - -- t1lib compiles and runs under Win32 using the cygwin32 toolkit. - - -- Maximum number of stem-hints enlarged (-> 256) because 128 were not enough - for complicated fonts. - - - -May 1999: t1lib-0.9 -------------------- - - -- Sub-Pixel positioning for Antialiasing functions enthanced (It was in fact - not correct before. - - -- Multiple Master fonts are rejected instead of SIGSEGV (nearly as - professional as supporting them ;) - - -- An additional set of functions allows access, filling and manipulation of - outlines. - - -- Functionality for non-antialiased "bytemaps". - - -- "Smart Antialiasing", allows to automatically let t1lib decide what AA-level - to use. The switchlimits are adjustable. - - -- An AFM-filename may explicitly be specified. This suppresses t1libīs search - for these files. This allows interfacing with other path search systems like - kpathsea. This was suggested by Nicolai Langfeldt (janl@math.uio.no). - - -- Some problems with aspect ratios different from 1 and transformed glyphs - fixed. - - -- Support for Right-To-Left typesetting. This might be experimental because I - don't know the rules for this exactly. - - -- In the context of Right-To-Left typesetting T1_ConcatGlyphs() expects one - additional argument "mode". - ATTENTION: This is an incompatible change with respect to V. 0.8. - - -- abort()-calls in type1-sources are caught by longjmp(). t1lib does not - any longer exit a program. Rather, errors may be handled by the user. - - -- If a rastering operation did not produce any black pixels, the rastering - fuctions do not return a NULL-glyph any longer. Rather, a glyph with the - correct metrics and NULL-bitmap pointer is returned. This seems to come - closer to accepted standards. - - -- The t1python-package is currently not distributed with t1lib because the - interface is not up to date. - - -- A lot of bugs fixed (and a lot of others introduced, of course :) - - - - -June 1999: t1lib-0.9.1 ---------------------- - - -- Several Bug-fixes, some functions that have been reported to be missing by - users, but no general new features. - - -- New functions T1_GetExtend(), T1_GetSlant() and T1_GetTransform() which give - access to currently active values of fontlevel transformations - - -- New function T1_GetNoKernPairs() which gives access to the number of defined - kerningpairs. - - -- New functions to query the grayvalue settings (T1_AAGetGrayValues(), - T1_AAHGetGrayValues() and T1_AANGetGrayValues()) - - -- Arbitrary linear transformations on fontlevel including caching using - T1_TransformFont() (on suggestion and patches by Derek B. Noonburg, - (derekn@foolabs.com) - - -- Introduction of the initialization flag T1_NO_AFM which suppresses use of - AFM data. This limits the functionality of t1lib considerably but - applications that do not need those advanced functions can gain some - performance boost while loading fonts because AFM files are not parsed and - the mapping tables are not setup (also by Derek B. Noonburg) - - -- xglyph clips output window for the function fonttable() to the physical - screen size. This is to prevent from freezing or exceeding resources if the - fonttable button had accidentally been pressed while a large size was active. - - -- The utility function T1_DumpPixmap() removed from API. New function - T1_XImageFromGlyph() added to X11 interface. This function allows, together - with the Xpm-library function XpmWriteFileFromImage(), to write xpm-files - from glyphs of arbitrary depths, colors, etc ... - - -- Functions T1_CopyOutline() and T1_FreeOutline() added to the outline interface. - - -- Fixed alignment problem on 64bit architecture. - - - -September 1999: t1lib-0.9.2: ----------------------------- - - -- Support for EMX-environments under MSDOS. This concerns the file locating - routines. - - -- t1lib now allows for charstring code 15 and escape code 15 by ignoring - these. They may appear in some old Adobe fonts. - - -- Makefiles are more independent of GNU make. - - -- Finally, undefined/missing characters are handled consistent in all rastering - functions by substituting .notdef. - - -- Several bug-fixes - - - -November 1999: t1lib-1.0: -------------------------- - - -- Bug-fixes. - - -- There happen to exist different assumptions about what exactly ISOLatin1Encoding - is. Especially the name for char 45 (dec) is not uniquely specified in - ISO 8859-1. Thus t1lib provides two encoding files ISOLatin1Encoding one - which (PSLatin1.enc) is compatible with PostScript Level 2 and above. - - - -March 2000: t1lib-1.0.1: -------------------------- - - -- A few bug Fixes. - - -- lenIV=-1 is now handled. According to an undocumented Adobe convention - lenIV=-1 indicates suppressing of charstring encryption. - - -- Patches to compile t1lib und MS Visual C++ 6.0. In case something goes - wrong, please contact Nakano Hideo (hideo@mb.infoeddy.ne.jp). - - - -February 2001: t1lib-1.1.0: ---------------------------- - - -- Bug Fixes. - - -- Functions T1_GetFontFilePath() and T1_GetAfmFilePath() which return the - complete path of the files used by t1lib. - - -- Fixed parser code which previously failed on ASCII-encrypted files in - which the hex-lines were separated by <LF><CR> instead of by <LF> (Yes, - there such DOSian files out there ...). - - -- Multiple inclusion protection for t1lib.h - - -- T1_QueryLigs() fixed. It did not work correct if successors and/or - ligatures were not in the current encoding. - - -- New patches for VMS by Martin P. J. Zinser (zinser@decus.de). - - -- Patch by Sergey Babkin (babkin@bellatlantic.net) to correct the rasterizer - to respect StdStemWidths. - - -- General support for font subsetting. - - -- Dokumentation also provided as pdf for those people who do not have LaTeX - installed. This is due to suggestions and patches by Nguyen-Dai Quy - (NDQ@iris.ltas.ulg.ac.be). - - - -April 2001: t1lib-1.1.1: ------------------------- - - -- Update to libtool-1.3.5. - - -- T1_GetFontBBox() also accepts specification consisting of floating point - numbers (as suggested by Derek B. Noonburg (derekn@foolabs.com)). - - -- Within the near future the t1lib-webpage will be no longer available - because I will change my employer. - - -- Similarly, the sources will be distributed from sunsite only from then on. - - -- The Author's eMail-address will also become invalid in the near future. The - new and hopefully permanent eMail.address will be "Rainer.Menzner@web.de". - - - -July 2001: t1lib-1.2: ----------------------- - - -- Fixed bug in subsetting code. - - -- Fixed bug in AFM-parser code. - - -- Fixed kerning mapping code. Kerning did not work correctly for characters - that appeared multiple times in an encoding vector. - - -- In the same context a new function, T1_GetEncodingIndices() has been added - to the API. It returns an array of indices (by contrast, - T1_GetEncodingIndex() returns only the lowest index found). - - -- Support for composite characters. - - -- Additional support for dvips encoding files (thanks to suggestion and - contribution by Nicolai Langfeldt (janl@linpro.no). - - -- Documentation is installed in PostScript and PDF format, but no longer in - DVI format. - - - -October 2001: t1lib-1.3: ------------------------- - - -- *Really* an update to libtool-1.3.5 - - -- Global Font Metrics Information is loaded from AFM files in order to be able - to read the typographic ascender. Line ruling did not behave as - documented. However, problems could still exist because the typographic - ascender specification is optional in AFMs. - - -- Reorganized search path handling and, in particular, the respective - documentation is more detailed. - - -- The configuration file now allows multiple lines of one type of search path - specification and it is also possible to quote path specification in order - to specify paths that contains special characters like spaces, colons, etc. - - -- Multiple font databases are supported. - - -- T1_PrintLog() extended to accept a variable argument list. - - -- The environment variable T1LIB_LOGMODE is evaluated to give the user the - chance to specify a loglevel and hence to detect t1lib-problems even if the - application programmer did not enable the log file features. - - -- Further bug fixes - - - -November 2001: t1lib-1.3.1: ---------------------------- - - -- Color problem in t1x11-module fixed. - - -- Fixes in AFM parser. Among others, Version had been read as name, instead of - as string. This led to a failure to scan global font info for some standard AFMs. - - -- Fixes in of OpenVMS special code - - -- Further Fixes - - - -January 2003: t1lib-5.0.0: --------------------------- - - -- Forced PostScript target in the doc directory to file. - - -- Subsetting code extended in order to ensure that components of - composite characters are also part of the subset. - - -- Hinting meachanism reworked in order to get rid of some - rasterizing artifacts. - - -- Experimental support for stroked fonts (PaintType=1) - - -- Experimental support for stroking standard ATM fonts with PaintType=0. - - -- For historical reasons, there happened to exist a few documented API - functions that did not adhere to the T1_... naming convention. After - considering the pro's and con's, I have decided to cleanup the interface, - thus making this version incompatible to the previous version. Especially - in the type1 subdirectory there are still a lot of global symbols, but at - least these are not part of the documented API. The following functions - are affected: - - CheckForInit() --> T1_CheckForInit() - CheckForFontID() --> T1_CheckForFontID() - T1_Get_no_fonts() --> T1_GetNoFonts() - - Furthermore, I have removed and made static a few functions which - accidentally had found their way into t1lib.h, but which had not been part - of the documented API. - - I'm sorry if this causes inconveniences ... - - -- The new version, 5.0.0, follows as consequence from the issues discussed - above. It is defined by the libtool quantities CURRENT, REVISION and AGE. - - -- Functions for drawing rectangles. - - -- Bug Fixes - - -- Please also have a look at the topic "Future" in README.t1lib-5.0.0. - - - -February 2004: t1lib-5.0.1: ---------------------------- - - -- Support for Flex was not adapted to the changes from 5.0.0. This led to - rasterization errors in fonts that use the Flex functionality --> fixed. - - -- Bug Fixes - - - -April 2004: t1lib-5.0.2: ------------------------- - - -- Changes not updated for this version - - - -Mai 2005: t1lib-5.1.0: ----------------------- - - -- Check against MultipleMasterFonts somewhat more tolerant, so that - Type 1 Fonts automatically created from Multiple Master Fonts (e.g. - using Mmpfb) should now be acceptable. - - -- The configure-machinery had been somewhat out of date and has been - updated. The distributed configure script has been generated by - AutoConf 2.59 and the redistributed libtool parts are taken from - GNU libtool 1.5.10. - - -- Top-Level TeX-file in the doc subdirectory adapted to recent TeX - systems' requirements. - - -- Added IsoLatin9.enc to distribution. - - -- Subsetting extended so that it works for SEAC-constructed composites - even if no AFM composite character information is available - - -- Somewhat more intelligent defaults for subsetting when composite - characters are included in the subset. - - -- Reallocation had been broken by relocation of internal StandardEncoding - vector. This problem turned out on systems where realloc() actually - returned a different pointer. - - -- Fix for outline code on 64bit systems. This involves a redefinition - of the T1_PATHPOINT struct. This should be uncritical because for 32bit - systems there is no difference, whereas on 64bit systems, this has never - worked correctly before. - - -- DESTDIR support in Makefile.in by Volker Zell - - -- Support for XLFD font database format (in which the fonts' names appear - in the first place on a line). - - -- Further Bug Fixes - - - -December 2006: t1lib-5.1.1: ---------------------------- - -- DESTDIR support was missing and has been addded in install-target for type1afm. - -- A bug fix in Anti-Aliasing subsampling code, which could make t1lib crash - under certain conditions. - -- Small number of further fixes, in particular with respect to the build - mechanism. - - - -December 2007: t1lib-5.1.2: ---------------------------- - -- Small number of fixes reported by users. The fixes pertain to a - vulnerability issue, memory access issues. - -- More decent handling if Encoding and / or FontBBox specification are missing - (which is invalid with respect to the specification, but recoverablel). |
