2002-02-09 Werner Lemberg <wl@gnu.org>
* README: Fix typo.
* docs/CHANGES: Minor fixes.
* Version 2.0.8 released.
=========================
2002-02-08 David Turner <david@freetype.org>
* docs/CHANGES: Updating for 2.0.8.
* include/freetype/freetype.h: Setting `PATCH_LEVEL' to 8 and
removing `FT_Get_Next_Char' from the API (temporarily).
* include/freetype/freetype.h: Adding comments to FT_Get_Next_Char;
note that this function might temporarily be removed for the 2.0.8
release.
2002-02-07 David Turner <david@freetype.org>
* src/pcf/pcfread.c (pcf_load_font): Removed immature support of
the AVERAGE_WIDTH property.
2002-02-06 David Turner <david@freetype.org>
* src/sfnt/sfobjs.c (SFNT_Load_Face): Since many fonts embedded in
PDF documents do not include 'cmap', 'post' and 'name' tables, the
SFNT face loader has been changed to not immediately report an
error if these are not present.
Note that the specification _requires_ these tables, but Adobe
seems to ignore it completely.
* src/sfnt/ttcmap.c: Removing compiler warnings.
* src/pcf/pcfread.c (pcf_read_TOC): Use FT_UInt.
(pcf_parse_metric, pcf_parse_compressed_metric): Removed. Code
is now in ...
(pcf_get_metric): Here.
(pcfSeekToType): Renamed to ...
(pcf_seek_to_table_type): This.
Use FT_Int.
(pcfHasType): Renamed to ...
(pcf_has_table_type): This.
Use FT_Int.
(find_property): Renamed to ...
(pcf_find_property): This.
Use FT_Int.
(pcf_get_bitmaps, pcf_get_encodings): Handle invalid PCF fonts
better (delaying format checks out of FT_Access_Frame ..
FT_Forget_Frame blocks to avoid leaving the stream in an incorrect
state when encountering an invalid PCF font).
* src/pcf/pcfdriver.c (PCF_Done_Face): Renamed to ...
(PCF_Face_Done): This.
(PCF_Init_Face): Renamed to ...
(PCF_Face_Init): This.
(PCF_Get_Char_Index): Renamed to ...
(PCF_Char_Get_Index): This.
(PCF_Get_Next_Char): Renamed to ...
(PCF_Char_Get_Next): This.
(pcf_driver_class): Updated.
* src/pcf/pcf.h (PCF_Done_Face): Removed.
2002-02-06 Detlef Würkner <TetiSoft@apg.lahn.de>
* src/pcf/pcfdriver.c (FT_Done_Face): Fixed small memory leak.
* src/pcf/pcfread.c (pcf_load_font): Now handles the `AVERAGE_WIDTH'
property to return correct character pixel (width/height) pairs for
embedded bitmaps.
2002-02-04 Keith Packard <keithp@keithp.com>
Adding the function `FT_Get_Next_Char', doing the obvious thing
w.r.t. the selected charmap.
* include/freetype/freetype.h: Add prototype.
* include/freetype/internal/ftdriver.h: Add `FTDriver_getNextChar'
typedef.
(FT_Driver_Class): Use it.
* include/freetype/internal/psnames.h: Add `PS_Next_Unicode_Func'
typedef.
(PSNames_Interface): Use it.
* include/freetype/internal/tttypes.h: Add `TT_CharNext_Func'
typedef.
(TT_CMapTable): Use it.
* src/base/ftobjs.c (FT_Get_Next_Char): New function, implementing
high-level API.
* src/cff/cffdrivr.c (cff_get_next_char): New function.
(cff_driver_class): Add it.
* src/cid/cidriver.c (Cid_Get_Next_Char): New function.
(t1cid_driver_class): Add it.
* src/pcf/pcfdriver.c (PCF_Get_Next_Char): New function.
(pcf_driver_class): Add it.
* src/psnames/psmodule.c (PS_Next_Unicode): New function.
(psnames_interface): Add it.
* src/sfnt/ttcmap.c (code_to_next0, code_to_next2, code_to_next4,
code_to_next6, code_to_next_8_12, code_to_next_10): New auxiliary
functions.
(TT_CharMap_Load): Use them.
* src/truetype/ttdriver.c (Get_Next_Char): New function.
(tt_driver_class): Add it.
* src/type1/t1driver.c (Get_Next_Char): New function.
(t1_driver_class): Add it.
* src/winfonts/winfnt.c (FNT_Get_Next_Char): New function.
(winfnt_driver_class): Add it.
* src/pcf/pcfread.c (pcf_load_font): For now, report Unicode for
Unicode and Latin 1 encodings.
2002-02-02 Keith Packard <keithp@keithp.com>
* builds/unix/freetype-config.in: Add missing `fi'.
* Version 2.0.7 released.
=========================
2002-02-01 David Turner <david@freetype.org>
* include/freetype/freetype.h: Increasing FREETYPE_PATCH to 7
for the new release.
2002-01-31 David Turner <david@freetype.org>
* README, README.UNX, docs/CHANGES: Updating documentation for the
2.0.7 release.
2002-01-30 David Turner <david@freetype.org>
* INSTALL: Moved to ...
* docs/INSTALL: Here to avoid conflicts with the `install' script on
Windows, where the filesystem doesn't preserve case.
2002-01-29 David Turner <david@freetype.org>
* configure: Fixed the script. It previously didn't accept more
than one argument correctly. For example, when typing:
./configure --disable-shared --disable-nls
the `--disable-nls' was incorrectly sent to the `make' program.
2002-01-29 Werner Lemberg <wl@gnu.org>
* README.UNX: Fix typo.
* builds/unix/install.mk (uninstall): Fix library name for libtool.
2002-01-28 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr>
* src/pcf/pcfdriver.c (PCF_Done_Face): Fix incorrect destruction of
the face object (face->toc.tables, face->root.family_name,
face->root.available_size, face->charset_encoding,
face->charset_registry are now freed). Thanks to Niels Moseley.
2002-01-28 Roberto Alameda <ojancano@geekmail.de>
* src/type1/t1load.c (parse_encoding): Set `loader->num_chars'.
2002-01-28 Werner Lemberg <wl@gnu.org>
* src/type1/t1load.c (parse_subrs, parse_charstrings): Use copy
of `base' string for decrypting to not modify the original data.
Based on a patch by Jakub Bogusz <qboosh@pld.org.pl>.
2002-01-27 Giuliano Pochini <pochini@shiny.it>
* src/smooth/ftgrays.c (gray_render_scanline): Fix bug which caused
bad rendering of thin lines (less than one pixel thick).
2002-01-25 Werner Lemberg <wl@gnu.org>
* src/cff/cffdrivr.c (cff_get_name_index): Make last patch work
actually.

2002-01-18 Ian Brown <ian.brown@printsoft.de>
* builds/win32/visualc/freetype.dsp: Updated.
2002-01-13 Werner Lemberg <wl@gnu.org>
* builds/unix/freetype2.a4: The script was still buggy.
* builds/unix/freetype-config.in: Make it really work for any install
prefix.
2002-01-10 Werner Lemberg <wl@gnu.org>
* builds/unix/freetype2.a4: Fix some serious bugs.
2002-01-09 David Turner <david@freetype.org>
* builds/unix/configure.ac: Build top-level Jamfile.
2002-01-09 Maxim Shemanarev <mcseemagg@yahoo.com>
* src/smooth/ftgrays.c (gray_render_line): Small optimization to
the smooth anti-aliased renderer that deals with vertical segments.
This results in a 5-7% speedup in rendering speed.
2002-01-08 David Turner <david@freetype.org>
Added some wrapper scripts to make the installation more
Unix-friendly.
* configure, install: New files.
* INSTALL, README.UNX: Updated installation documentation to use the
new 'configure' and 'install' scripts.
2002-01-07 David Turner <david@freetype.org>
* Version 2.0.6 released.
=========================
* docs/BUGS, docs/CHANGES: Updating documentation for 2.0.6 release.
* src/tools/docmaker.py: Fixed HTML quoting in sources.
(html_format): Replaced with ...
(html_quote): New function.
(html_quote0): New function.
(DocCode::dump_html): Small improvement.
(DocParagraph::dump, DocBlock::html): Use html_quote0 and html_quote.
* include/freetype/config/ftoption.h: Setting default options for
a release build (debugging off, bytecode interpreter off).
* src/base/ftobjs.c, src/base/ftoutln.c, src/cache/ftccmap.c,
src/cff/cffload.c, src/cff/cffobjs.c, src/pshinter/pshalgo2.c,
src/sfnt/ttload.c, src/sfnt/ttsbit.c: Removing small compiler
warnings (in pedantic compilation modes).
2002-01-05 David Turner <david@freetype.org>
* src/autohint/ahhint.c (ah_align_linked_edge): Modified computation
of auto-hinted stem widths; this avoids color fringes in
`ClearType-like' rendering.
* src/truetype/ttgload.c (TT_Load_Glyph_Header,
TT_Load_Simple_Glyph, TT_Load_Composite_Glyph, load_truetype_glyph):
Modified the TrueType loader to make it more paranoid; this avoids
nasty buffer overflows in the case of invalid glyph data (as
encountered in the output of some buggy font converters).
2002-01-04 David Turner <david@freetype.org>
* README.UNX: Added special README file for Unix users.
* builds/unix/ftsystem.c (FT_New_Stream): Fixed typo.
* src/base/ftobjs.c: Added #include FT_OUTLINE_H to get rid
of compiler warnings.

* src/type1/t1objs.c (T1_Face_Init): Add cast to avoid compiler
warning.
2002-01-03 Keith Packard <keithp@keithp.com>
* builds/unix/ftsystem.c (FT_New_Stream): Added a fix to ensure that
all FreeType input streams are closed in child processes of a `fork'
on Unix systems. This is important to avoid (potential) access
control issues.
2002-01-03 David Turner <david@freetype.org>
* src/type1/t1objs.c (T1_Face_Init): Fixed a bug that crashed the
library when dealing with certain weird fonts like `Stalingrad', in
`sadn.pfb' (this font has no full font name entry).
* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):
New function to check the consistency of outline data.
* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to
ensure that loaded glyphs are valid. This allows certain fonts like
`tt1095m_.ttf' to be loaded even though it appears they contain
really funky glyphs.
There still is a bug there, though.
* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.
2001-12-30 David Turner <david@freetype.org>
* src/autohint/ahhint.c (ah_hinter_load): Fix advance width
computation of auto-hinted glyphs. This noticeably improves the
spacing of letters in KDE and Gnome.
2001-12-25 Antoine Leca <Antoine-Freetype@Leca-Marti.org>
* builds/dos/detect.mk: Correcting the order for Borland compilers:
16-bit bcc was never selected, always overridden by 32-bit bcc32.
2001-12-22 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr>
* src/pcf/pcfread.c (pcf_load_font): Handle property `POINT_SIZE'
and fix incorrect computation of `available_sizes'.
2001-12-22 David Turner <david@freetype.org>
* src/autohint/ahhint.c (ah_hinter_load): Auto-hinted glyphs had an
incorrect glyph advance in the case of mono-width fonts (like
Courier, Andale Mono, and others).
2001-12-22 Detlef Würkner <TetiSoft@apg.lahn.de>
* builds/amiga/*: Adaptations to latest changes.
Support added for MorphOS.
2001-12-22 Werner Lemberg <wl@gnu.org>
* src/pshinter/pshrec.c (FT_COMPONENT): Redefine to `trace_pshrec'.

ps_hints_t1stem3, ps_hints_t2mask, ps_hints_t2counter): Fix
FT_ERROR messages.
* src/pshinter/pshalgo1.c (FT_COMPONENT): Define as
`trace_pshalgo1'.
* src/pshinter/pshalgo2.c (FT_COMPONENT): Define as

2001-12-21 David Turner <david@freetype.org>
* src/pshinter/pshrec.c (ps_hints_t2mask, ps_hints_t2counter):
Ignore invalid `hintmask' and `cntrmask' operators (instead of
returning an error). Glyph 2028 of the CFF font `MSung-Light-Acro'
couldn't be rendered otherwise (it seems its charstring is buggy,
though this requires more analysis).
(FT_COMPONENT): Define.
* src/cff/cffgload.c (CFF_Parse_CharStrings), src/psaux/t1decode.c
(T1_Decoder_Parse_Charstrings), src/pshinter/pshalgo2.c (*), Fixed a
bug where the X and Y axis where inverted in the postscript hinter.
This caused problem when displaying on non-square surfaces.
* src/pshinter/pshalgo2.c: s/vertical/dimension/.
* src/pshinter/pshglob.c (psh_globals_new): Replaced a floating
point constant with a fixed-float equivalent. For some reasons not
all compilers are capable of directly computing a floating pointer
constant casted to FT_Fixed, and will link a math library instead.
2001-12-20 Werner Lemberg <wl@gnu.org>
* src/cache/ftccache.c (ftc_node_destroy, ftc_cache_lookup): Fix
tracing strings.
* src/cache/ftccmap.c (ftc_cmap_family_init): Ditto.

* src/cid/cidobjs.c (CID_Face_Done): Fixed a memory leak; the subrs
routines were never released when CID faces were destroyed.
* src/cff/cffload.h, src/cff/cffload.c, src/cff/cffgload.c: Updated
to move the definition of encoding tables back within `cffload.c'
instead of making them part of a shared header (causing problems in
`multi' builds). This reverts change 2001-08-08.
* docs/CHANGES: Updated for 2.0.6 release.
* docs/TODO: Added `stem3 and counter hints support' to the TODO
list for the Postscript hinter.
* docs/BUGS: Closed the AUTOHINT-NO-SBITS bug.
2001-12-19 David Turner <david@freetype.org>
* include/freetype/cache/ftcache.h: Added comments to indicate that
some of the exported functions should only be used by applications
that need to implement custom cache types.
* src/truetype/ttgload.c (cur_to_org, org_to_cur): Fixed a nasty bug
that prevented composites from loading correctly, due to missing
parentheses around macro parameters.
* src/sfnt/sfobjs.c (SFNT_Load_Face): Make the `post' and `name'
tables optional to load PCL fonts properly.
* src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c
(FT_Load_Glyph), include/freetype/freetype.h (FT_LOAD_SBITS_ONLY):
`Fixed' the bug that prevented embedded bitmaps to be loaded when
the auto-hinter is used. This actually is a hack but will be enough
until the internal re-design scheduled for FreeType 2.1.
* src/raster/ftrend1.c (ft_raster1_render): Fixed a nasty outline
shifting bug in the monochrome renderer.
* README: Updated version numbers to 2.0.6.
2001-12-17 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (load_truetype_glyph): Fix test for invalid
glyph header.

already in ftcmanag.h.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Remove unused variable
`gfam'.

* builds/mac/README: Updated.
2001-12-14 Scott Long <scott@swiftview.com>
* src/truetype/ttgload.c (load_truetype_glyph): Fixing crash when
dealing with invalid fonts (i.e. glyph size < 10 bytes).
2001-12-14 Sam Latinga <slouken@devolution.com>
* builds/mac/freetype.make: A new Makefile to build with MPW on
MacOS classic.
2001-12-14 David Turner <david@freetype.org>
* src/truetype/ttgload.c (TT_Load_Glyph), src/type1/t1gload.c
(T1_Load_Glyph), src/cid/cidgload.c (CID_Load_Glyph),
src/cff/cffgload.c (CFF_Load_Glyph): Fixed a serious bug common to
all font drivers (the advance width was never hinted when it
should).
* include/freetype/freetype.h (FREETYPE_PATCH): New macro.

use `extern' keyword.
2001-12-12 David Turner <david@freetype.org>
* src/pshinter/pshglob.c (psh_blues_scale_zones, psh_blues_snap_stem
psh_globals_new): Adding correct BlueScale/BlueShift support, plus
family blues processing.
* src/pshinter/pshglob.h (PSH_BluesRec): Updated.
Started adding support for the Postscript hinter in the CFF module.
* src/cff/cffgload.c: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.
(CFF_Parse_CharStrings): Implement it.
* src/cff/cffgload.h: Updated.

passing `-L/usr/lib' to gcc.
* docs/FTL.TXT: Simple fix (change `LICENSE.TXT' to `FTL.TXT').
* builds/unix/freetype2.m4: New file for checking configure paths.
We need to install it in $(prefix)/share/aclocal/freetype2.m4 but I
didn't modify builds/unix/install.mk yet.
* INSTALL: Updated the instructions to build shared libraries with
Jam. They were simply wrong.
* src/base/fttrigon.c (FT_Cos): Fixed a small bug that caused
slightly improper results for `FT_Cos' and `FT_Sin' (example:
FT_Sin(0) == -1!).
2001-12-11 Detlef Würkner <TetiSoft@apg.lahn.de>
* include/freetype/internal/ftstream.h (GET_LongLE, GET_ULongLE):
Fixed incorrect argument types.
2001-12-10 Francesco Zappa Nardelli <Francesco.Zappa.Nardelli@ens.fr>
* src/pcf/pcfdriver.c (PCF_Init_Face): Allow Xft to use PCF fonts
by setting the `face->metrics.max_advance' correctly.
2001-12-07 David Turner <david@freetype.org>
* include/freetype/cache/ftccmap.h, src/cache/ftccmap.c: Added new
charmap cache.
* src/cache/ftcache.c: Updated.
* src/autohint/ahhint.c (ah_hinter_hint_edges): s/UNUSED/FT_UNUSED/.
2001-12-06 Leonard Rosenthol <leonardr@lazerware.com>

debugging purposes.
Comment out use of `origin'.
* src/smooth/ftsmooth.c (ft_smooth_render): Fixed a nasty hidden bug
where outline shifting wasn't correctly undone after bitmap
rasterization. This created problems with certain glyphs (like '"'
of certain fonts) and the cache system.
* src/pshinter/pshalgo1.c (psh1_hint_table_init): Fix typo.
* src/pshinter/pshalgo2.c (psh2_hint_table_init): Fix typo.
(ps2_hints_apply): Small fix.
2001-12-05 David Turner <david@freetype.org>
* src/pshinter/pshalgo2.c (psh2_hint_table_init),
src/pshinter/pshalgo1.c (psh1_hint_table_init): Removed compiler
warnings.
* include/freetype/ftcache.h, include/freetype/cache/*, src/cache/*:
Yet another massive rewrite of the caching sub-system in order to
both increase performance and allow simpler cache sub-classing. As
an example, the code for the image and sbit caches is now much
simpler.
I still need to update the documentation in
www/freetype2/docs/cache.html to reflect the new design though.
* include/freetype/config/ftheader.h (FT_CACHE_CHARMAP_H): New
macro.
(FT_CACHE_INTERNAL_CACHE_H): Updated.
2001-12-05 David Krause <freetype@davidkrause.com>
* docs/license.txt: s/X Windows/X Window System/.
2001-12-04 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c: Fix definition condition of MEM_Set().
* src/smooth/ftgrays.c (M_Y): Change value to 192.
* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.

variable.
* src/raster/ftraster.c (MEM_Set): Move definition down to avoid
compiler warning.
* src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to
avoid compiler warnings.
* src/pcf/pcfread.c (tableNames): Use `const'.
(pcf_read_TOC): Change counter name to avoid compiler warning.
Use `const'.
* src/pshinter/pshrec.c (ps_hints_close): Remove redundant
declaration.
* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
to avoid shadowing.
* src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto.
* src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()'
and `T1_Size_Done()'.
2001-11-20 Antoine Leca <antoineleca@multimania.com>
* include/freetype/ttnameid.h: Added some new Microsoft language
codes and LCIDs as found in MSDN (Passport SDK). Also added
comments about the meaning of bit 57 of the `OS/2' table
(TT_UCR_SURROGATES) which (with OpenType v.1.3) now means `there is
a character beyond 0xFFFF in this font'. Thanks to Detlef Würkner
<TetiSoft@apg.lahn.de> for noticing this.
2001-11-20 David Turner <david@freetype.org>
* src/pshinter/{pshalgo2.c, pshalgo1.c}: Fixed stupid bug in sorting
routine that created nasty alignment artefacts.
* src/pshinter/pshrec.c, tests/gview.c: Debugging updates.
* src/smooth/ftgrays.c: De-activated experimental gamma support.
Apparently, `optimal' gamma tables depend on the monitor type,
resolution and general karma, so it's better to compute them outside
of the rasterizer itself.
(gray_convert_glyph): Use `volatile' keyword.
2001-10-29 David Turner <david@freetype.org>
Adding experimental `gamma' support. This produces smoother glyphs
at small sizes for very little cost.
* src/smooth/ftgrays.c (grays_init_gamma): New function.
(gray_raster_new): Use it.
Various fixes to the auto-hinter. They merely improve the output of
sans-serif fonts. Note that there are still problems with serifed
fonts and composites (accented characters).
* src/autohint/ahglyph.c (ah_outline_load,
ah_outline_link_segments): Implement it.
Fix typos.
(ah_outline_save, ah_outline_compute_segments): Fix typos.
* src/autohint/ahhint.c (ah_align_serif_edge): New argument
`vertical'. Implement improvement.
(ah_hint_edges_3, ah_hinter_hint_edges): Implement it.
Fix typos.
(ah_hinter_align_strong_points, ah_hinter_align_weak_points): Fix
typos.
(ah_hinter_load): Set `ah_debug_hinter' if DEBUG_HINTER is defined.
* src/autohint/ahmodule.c: Implement support for DEBUG_HINTER macro.
* src/autohint/ahtypes.h: Ditto.
(AH_Hinter): Remove `disable_horz_edges' and `disable_vert_edges'
(making them global as `ah_debug_disable_horz' and
`ah_debug_disable_vert').
Fix typos.
* tests/gview.c: Updated the debugging glyph viewer to show the
hints generated by the `autohint' module.
2001-10-27 David Turner <david@freetype.org>
* src/cache/ftcchunk.c (ftc_chunk_cache_lookup): Fixed a bug that
considerably lowered the performance of the abstract chunk cache.
2001-10-26 David Turner <david@freetype.org>
* include/freetype/ftcache.h, include/freetype/cache/*.h,
src/cache/*.c: Major re-design of the cache sub-system to provide
better performance as well as an `Acquire'/`Release' API. Seems to
work well here, but probably needs a bit more testing.
2001-10-26 Leonard Rosenthol <leonardr@lazerware.com>
* builds/mac/README: Updated to reflect my taking over the project
and that is now being actively maintained.
* src/base/ftmac.c (parse_fond): Applied patches from Paul Miller
<paulm@profoundeffects.com> to support loading a face other than the
first from a FOND resource.
(FT_New_Face_From_FOND): Updated.
2001-10-25 Leonard Rosenthol <leonardr@lazerware.com>
* builds/mac/ftlib.prj: Update of CodeWarrior project file for Mac
OS for latest version (7) of CWPro and for recent changes to the FT
source tree.
2001-10-25 David Turner <david@freetype.org>
* include/freetype/config/ftoption.h: Updated comments to explain
precisely how to use project-specific macro definitions without
modifying this file manually.
(FT_CONFIG_FORCE_INT64): Define.
(FT_DEBUG_MEMORY): New macro.
2001-10-24 Tom Kacvinsky <tkacvins@freetype.org>
* builds/unix/ftsystem.c (FT_New_Memory): Added a missing `{'.
2001-10-23 David Turner <david@freetype.org>
* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
Improvements to the memory debugger to report more information in
case of errors. Also, some allocations that occurred through REALLOC
couldn't be previously caught correctly.
* src/autohint/ahglyph.c (ah_outline_compute_segments,
ah_outline_compute_edges), src/raster/ftraster.c (ft_black_new),
src/smooth/ftgrays.c (gray_render_span, gray_raster_new): Replaced
liberal uses of memset() by the MEM_Set() macro.
2001-10-23 David Turner <david@freetype.org>
* src/raster/ftraster.c (Update): Removed to be inlined in ...
(Sort): Updated.
2001-10-22 David Turner <david@freetype.org>
* builds/unix/ftsystem.c (FT_New_Memory, FT_Done_Memory),
builds/vms/ftsystem.c (FT_New_Memory, FT_Done_Memory),
builds/amiga/ftsystem.c (FT_New_Memory, FT_Done_Memory),
src/base/ftdbgmem.c: Updated the memory debugger and
platform-specific implementations of `ftsystem' in order to be able
to debug memory allocations on Unix, VMS and Amiga too!
* src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): Removed
some bogus warnings.
* include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
Modified the debugging memory manager to report the location (source
file name + line number) where leaked memory blocks are allocated in
the source file.
* src/base/ftdbgmem.c: New debugging memory manager. You must
define the FT_DEBUG_MEMORY macro in `ftoption.h' to enable it. It
will record every memory block allocated and report simple errors
like memory leaks and double deletes.
* src/base/Jamfile: Include ftdbgmem.
* src/base/rules.mk: Ditto.
* src/base/ftbase.c: Include ftdbgmem.c.
* include/freetype/config/ftoption.h: Added the FT_DEBUG_MEMORY
macro definition.
* src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): Modified the
base component to use the debugging memory manager when the macro
FT_DEBUG_MEMORY is defined.

* src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if
we are working with a CID keyed CFF font. Otherwise, a variable
that was never allocated memory might freed. This is a correction
to the previous patch for freeing subfonts.
2001-10-21 Tom Kacvinsky <tkacvins@freetype.org>
* src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to
avoid a memory leak.
2001-10-21 David Turner <david@freetype.org>
* src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c,
src/pshinter/pshglob.c: Removing compiler warnings in pedantic modes
(in multi-object compilation mode, mainly).
2001-10-20 Tom Kacvinsky <tkacvins@freetype.org>
* src/type1/t1load.c (parse_encoding): Add a test to make sure
that custom encodings (i.e., neither StandardEncoding nor
ExpertEncoding) are not loaded twice when the Type 1 font is
synthetic.
* src/type1/t1load.c (parse_font_name, parse_subrs): Added a test
for when loading synthetic fonts to make sure that the font name
and subroutines are not loaded twice. This is to remove a memory
leak that occurred because the original memory blocks for these
objects were not deallocated when the objects were parsed the
second time.

* src/smooth/ftgrays.c, src/pshinter/pshglob.h,
src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: Getting rid of
compiler warnings.
* src/pshinter/module.mk, src/pshinter/rules.mk: Adding control
files to build the PostScript hinter with the `old' build system.
2001-10-19 Jacob Jansen <joukj@hrem.stm.tudelft.nl>
* descrip.mms, src/pshinter/descrip.mms: Updates to the VMS build
files.
2001-10-18 David Turner <david@freetype.org>
* src/psnames/pstables.h, src/tools/glnames.py: Rewrote the
`glnames.py' script used to generate the `pstables.h' header file.
The old one contained a serious bug that made FreeType return
incorrect glyph names for certain glyphs.
* src/truetype/ttdriver.c (Set_Char_Sizes): Changing computation of
pixel size from character size to use rounding. This is an
experiment to see whether this gives values similar to Windows for
scaled ascent/descent/etc.
* src/base/ftcalc.c (FT_Div64by32): Changed the implementation
slightly since the original code was mis-compiled on Mac machines
using the MPW C compiler.
* src/base/ftobjs.c (FT_Realloc): When a memory block was grown
through FT_Realloc(), the new bytes were not set to 0, which created
some strange bugs in the PostScript hinter.
(destroy_face): Don't deallocate unconditionally.
* src/cid/cidgload.c (CID_Compute_Max_Advance, CID_Load_Glyph):
Adding support to new PostScript hinter.
* include/freetype/internal/psglobal.h,
include/freetype/internal/pshints.h,
include/freetype/config/ftmodule.h, src/pshinter/Jamfile,
src/pshinter/pshalgo.h, src/pshinter/pshalgo1.h,

src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c,
src/pshinter/pshrec.h: Adding new PostScript hinter module.
* include/freetype/internal/ftobjs.h,
include/freetype/internal/internal.h,
include/freetype/internal/psaux.h,
include/freetype/internal/t1types.h, src/psaux/psobjs.c,

src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c,
src/type1/t1objs.h: Updates to use the new PostScript hinter.
* tests/Jamfile, tests/gview.c: Adding a new glyph hinting
viewer/debugger to the source tree. Note that you will _not_ be
able to compile it since it depends on an unavailable graphics
library named `Nirvana' to render vector images.
2001-10-17 David Turner <david@freetype.org>
* Version 2.0.5 released.
=========================
* include/freetype/freetype.h, include/internal/ftobjs.h,
src/base/ftobjs.c, src/type1/t1driver.c: Adding a new function named
'FT_Get_Postscript_Name' to retrieve the PostScript name of a given
font. Should work with all formats except pure CFF/CEF fonts (this
will be added soon).
* src/cid/cidriver (cid_get_postscript_name): New function.
(CID_Get_Interface): Handle `postscript_name' interface.
* src/sfnt/sfdriver.c (get_sfnt_postscript_name): New function.
(SFNT_Get_Interface): Handle `postscript_name' interface.
* src/type1/t1driver.c (t1_get_ps_name): New function.
(Get_Interface): Handle `postscript_name' interface.
* README, docs/CHANGES: Updated for 2.0.5 release.
2001-10-08 David Turner <david@freetype.org>
Fixed a bug in `glnames.py' that prevented it from generating
correct glyph names tables. This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).
* src/tools/glnames.py (mac_standard_names): Fixed.
(t1_standard_strings): Some fixes and renamed to ...
(sid_standard_names): This.
(t1_expert_encoding): Fixed.
(the_adobe_glyph_list): Renamed to ...
(adobe_glyph_names): This.
(the_adobe_glyphs): Renamed to ...
(adobe_glyph_values): This.
(dump_mac_indices, dump_glyph_list, dump_unicode_values, main):
Updated.
* src/psnames/pstables.h: Regenerated.
* src/psnames/psmodule.c (PS_Unicode_Value): Fix offset.
Fix return value.
Use `sid_standard_table' and `ps_names_to_unicode' instead of
`t1_standard_glyphs' and `names_to_unicode'.
(PS_Macintosh_Name): Use `ps_glyph_names' instead of
`standard_glyph_names'.
(PS_Standard_Strings): Use `sid_standard_names' instead of
`t1_standard_glyphs'.
* doc/BUGS, doc/TODO: New documents.
2001-10-07 Richard Barber <rich@solutionuk.com>
* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.
2001-10-07 David Turner <david@freetype.org>
setjmp() and longjmp() are now used for rollback (i.e. when memory
pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.
* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
too small on 16-bit systems). <limits.h> is included to properly
