David Turner 4d57024d 2002-02-24T02:59:24 * moving all code related to glyph loaders to "internal/ftgloadr.h" and "src/base/ftgloadr.c". Note also that the type "FT_GlyphLoader" is now a pointer to the structure "FT_GlyphLoaderRec"..
Werner Lemberg a7d2f5e1 2002-02-19T01:12:23 * src/autohint/ahglyph.c (ah_outline_link_segments): Remove unused variables. * src/autohint/ahhint.c (ah_align_serif_edge): Use FT_UNUSED instead of UNUSED. * src/autohint/ahmodule.c (ft_autohinter_reset): Ditto. * src/pshinter/pshrec.c (ps_mask_table_merge): Fix typo in variable swapping code. * src/pshinter/pshglob.h (PSH_Blue_Align): Add PSH_BLUE_ALIGN_NONE. * src/pshinter/pshglob.c (psh_blues_snap_stem): Use it. * src/pshinter/pshalgo1.c (psh1_hint_table_optimize): Ditto. * src/pshinter/pshalgo2.c (psh2_hint_align): Ditto. * include/freetype/internal/ftobjs.h (UNUSED): Removed.
David Turner f7f82d77 2002-01-06T10:13:40 the TrueType glyph loader is now much more paranoid, this avoids unpleasant overwrites in the case of invalid glyph data (found in the output of buggy font converters) the computation of auto-hinted stem widths has been modified to avoid certain color fringes in LCD-decimation rendering (a.k.a. "ClearType")
David Turner 1127b2bf 2001-12-30T01:30:11 improving the computation of the advance widths of auto-hinted glyphs, in order to produce better letter spacing..
Werner Lemberg 3681e37d 2001-12-23T00:56:36 Formatting.
David Turner 9a9edc66 2001-12-22T16:07:52 fixing the autohinter: the advance of auto-hinted glyphs in mono-spaced fonts was incorrect
Werner Lemberg e9e130c0 2001-12-07T21:56:32 Formatting.
David Turner 14183ea0 2001-12-05T15:59:33 First of all, a big thanks to Werner and Antoine for their latest work !! * src/pshinter/pshalgo2.c (psh2_hint_table_init), src/pshinter/pshalgo1.c (psh1_hint_table_init): removed compiler warnings * 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..
Werner Lemberg c3b21608 2001-12-05T01:22:05 Formatting. Cleaning up of ChangeLog. * docs/license.txt: s/X Windows/X Window System/. * 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. Remove unused variable. * src/cache/ftcimage.c (ftc_image_node_init, ftc_image_node_compare): Remove unused variables. * src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused 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()'.
David Turner adf07a93 2001-10-30T23:51:24 * src/smooth/ftgrays.c: adding experimental "gamma" support. This produces smoother glyphs at small sizes for very little cost * src/autohint/ahglyph.c, src/autohint/ahhint.c: 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) * tests/gview.c: updated the debugging glyph viewer to show the hints generated by the "autohint" module
David Turner 9d7e5e8b 2001-10-29T17:22:12 other auto-hinter experiments not worthy of a Changelog entry
David Turner b92479b8 2001-10-29T10:45:57 experimental changes to debug the auto-hinter. These are not worthy of a Changelog entry yet..
David Turner a11cd4e1 2001-10-26T07:21:38 a few updates used to debug the auto-hinter as well as try to improve it significantly
Werner Lemberg a560a1e0 2001-07-03T12:45:24 * src/autohint/ahhint.c (ah_hinter_align_weak_points): Remove unused variable `edges'. (ah_hinter_load): Remove unused variables `old_width' and `new_width'. * src/cid/cidload.c (cid_decrypt): Use `U' for constant (again). * src/psaux/psobjs.c (T1_Decrypt): Ditto. * src/type1/t1parse.c (T1_Get_Private_Dict): Ditto.

Werner Lemberg f814d0fa 2001-06-27T16:18:10 First round in converting type foo ( ... ) to type foo ( ... ) Other minor formatting issues.
David Turner 8edbcabc 2001-06-19T08:28:24 - updated doc for FT_New_Memory_Face - removed lots of compiler warnings in lint-style warning modes (/W4 with Visual C++)
Werner Lemberg cf24d515 2001-06-18T14:23:45 Minor cleanups to remove compiler warnings. * include/freetype/cache/ftcmanag.h (FTC_MAX_BYTES_DEFAULT): Use `L' for constant. * include/freetype/config/ftoption.h (FT_RENDER_POOL_SIZE): Ditto. * src/base/ftcalc.c (FT_MulDiv): Use `L' for constant. * src/base/ftglyph.c (FT_Glyph_Get_CBox): Remove `error' variable. * src/base/fttrigon.c (ft_trig_arctan_table): Use `L' for constants. * src/base/ftobjs.c (FT_Done_Size): Fix return value.

David Turner 0ebd3338 2001-06-08T10:54:43 * src/autohint/ahhint.c (ah_hinter_load_glyph): fixed a bug that corrupted transformed glyphs that were auto-hinted (the transform was applied twice !!)
Werner Lemberg 1f7f0e87 2001-06-06T17:30:41 Complete redesign of error codes. Please check ftmoderr.h for more details. * include/freetype/internal/cfferrs.h, include/freetype/internal/tterrors.h, include/freetype/internal/t1errors.h: Removed. Replaced with files local to the module. All extra error codes have been moved to `fterrors.h'. * src/sfnt/ttpost.h: Move error codes to `fterrors.h'. * src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h, src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h, src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h, src/smooth/ftsmerrs.h, src/truetype/tterrors.h, src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the error names for the module it belongs to. * include/freetype/ftmoderr.h: New file, defining the module error offsets. Its structure is similar to `fterrors.h'. * include/freetype/fterrors.h (FT_NOERRORDEF): New macro. (FT_ERRORDEF): Redefined to use module error offsets. All internal error codes are now public; unused error codes have been removed, some are new. * include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New macro. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro. All other source files have been updated to use the new error codes; some already existing (internal) error codes local to a module have been renamed to give them the same name as in the base module. All make files have been updated to include the local error files. * src/cid/cidtokens.h: Replaced with... * src/cid/cidtoken.h: This file for 8+3 consistency. * src/raster/ftraster.c: Use macros for header file names.
David Turner 66cb4790 2001-05-14T14:04:23 * src/base/ftcalc.c (FT_DivFix): fixed a bug in the 64-bit code that created incorrect scale factors !! * src/autohint/ahglobal.c, src/autohint/ahglyph.c, src/autohint/ahhint.c: fixed the incorrect blue zone computations, and improved the composite support. Note that these changes result in improved rendering, while sometimes introducing their own artefacts. That's probably the last big change to the autohinter before the introduction of its complete replacement..
David Turner 8d3a401f 2001-03-20T11:14:24 * builds/*/*-def.mk: changed the objects directory from "obj" to "objs" * include/freetype/config/ftheader.h: removed obsolete macros like FT_SOURCE_FILE, etc.. and added cache-specific macro definitions that were previously defined in <freetype/ftcache.h>. Added comments to be included in a new API Reference section. * src/*/*: removed the use of FT_SOURCE_FILE, etc.. now, each component needs to added its own directory to the include path at compile time. Modified all "rules.mk" and "descrip.mms" accordingly..
Werner Lemberg e274cfd3 2001-03-04T21:53:08 * src/autohint/ahtypes.h (AH_Hinter): Add elements `disable_horz_edges', `disable_vert_edges'. * src/autohint/ahhint.c (ah_hint_edges_3, ah_hinter_hint_edges): Use them (and remove static variables with the same names). * src/pcf/pcfutil.c (BitOrderInvert): Add `const'. * docs/glnames.py: Updated to latest pstables.h changes. * src/psnames/pstables.h: Add more `const'. * src/pcf/pcfutil.c: Ditto. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixing typo (FT_Glyph_Done -> FT_Done_Glyph). * include/freetype/ttnameid.h: Added some new Microsoft language codes and LCIDs as found in Office Xp. * builds/hurd/detect.mk: New file. Added support to detect the GNU Hurd operating system as Unix-like. Fix submitted by Anthony Fok <foka@debian.org>. * src/type1/t1gload.c (T1_Load_Glyph): Set glyph control data to the the Type 1 glyph charstring (used by conversion programs). Submitted by Ha Shao <hashao@chinese.com>. * src/base/ftgrays.c (grays_sweep): The function didn't exit immediately if `num_cells' was 0 as it should. Thanks to Boris for finding this out. * src/base/ftglyph.c (FT_Glyph_To_Bitmap): Fixed memory leak when bitmap rendering fails (thanks to Graham Asher). * docs/docmaker.py, include/freetype/*.h: Updated the DocMaker script to support chapters and section block ordering. Updated the public header files accordingly. * src/base/ftglyph.c (FT_Glyph_Copy): Advance width and glyph format were not correctly copied.
Tom Kacvinsky 45fbecbb 2000-12-22T07:24:02 Removed unnecessary comments and commented-out code from ah_hinter_load_glyph.
Tom Kacvinsky f8d841a7 2000-12-21T01:25:13 Changed functions ah_hinter_load and ah_hinter_load_glyph so that synthetic fonts render correctly. Previously, the first glyph rendered from such a font did not have the FontMatrix applied.
David Turner 170c0d4c 2000-12-13T19:55:11 * include/freetype/config/ft2build.h, include/freetype/internal/internal.h: fixed header inclusion macros to use direct definitions. This is the only way to do these things in a portable way :-( The rest of the code should follow shortly though everything compiles now.. * builds/compiler/intelc.mk, builds/compiler/watcom.mk, builds/win32/detect.mk: added support for the Intel C/C++ compiler, as well as _preliminary_ (read: doesn't work !!) support for Watcom. Also added a new setup target. Type "make setup list" for a list of supported command-line compilers on Win32..
Werner Lemberg d5c1b27d 2000-12-12T22:28:12 * include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT): Removed. ANSI C doesn't (explicitly) allow macro expansion in arguments using `##'. (FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory names directly. Make them configurable. Use `##' to strip leading and trailing spaces from arguments. * builds/unix/ft2unix.h: Adapted. * src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream, ft_close_stream): Use FT_CALLBACK_DEF. * builds/unix/ftsystem.c: Use new header scheme. (FT_Done_Memory): Use free() from FT_Memory structure. * src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes. * include/freetype/config/ft2build.h (FT2_CONFIG_ROOT, FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE, FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.
Werner Lemberg cc069beb 2000-12-08T16:17:16 cleanups
David Turner 19ed8afe 2000-12-08T02:42:29 - updated all source files to adhere to the new inclusion scheme - the CFF loader now loads the encodings and charset tables though doesn't use them for now
Werner Lemberg 5c4f5ebd 2000-11-18T04:42:41 formatting
David Turner e006675e 2000-11-16T19:06:28 added support to synthetic Type 1 fonts. Why didn't this thing get committed ??
David Turner a6c747d2 2000-11-08T19:44:48 fixed a small bug: the "linearHoriAdvance" and "vertHoriAdvance" were not set correctly when the auto-hinter is used to load/hint a glyph..
David Turner 54e75749 2000-11-04T02:52:02 defining new types to hold "internal" fields of public objects: FT_Face_Internal, FT_Size_Internal, FT_Slot_Internal these contain some fields that may change between releases of FreeType, without affecting the size of FT_FaceRec, FT_SizeRec, FT_GlyphSlotRec, etc.., which means that drivers wouldn't need to be recompiled if we only add new fields to an internal structure.. I plan to hack a few things related to the auto-hinter and I need this move to ensure that we will not break binary compatibility between 2.0 and 2.1 :-) - David
David Turner 76a5f623 2000-11-04T01:55:49 major reformatting of the sources: FT_EXPORT_DEF => FT_EXPORT FT_EXPORT_FUNC => FT_EXPORT_DEF BASE_DEF => FT_BASE BASE_FUNC => FT_BASE_DEF LOCAL_DEF => FT_LOCAL LOCAL_FUNC => FT_LOCAL_DEF LOCAL_FUNC_X => FT_CALLBACK_DEF LOCAL_DEF_X => FT_CALLBACK_TABLE FT_CPLUSPLUS => FT_CALLBACK_TABLE_DEF
Werner Lemberg e4b32a5d 2000-10-31T20:42:18 Removing trailing whitespace.
David Turner a39acf55 2000-08-23T02:47:57 updated "psaux" and "type1z". The Type 1 driver now completely relies on "psaux". I now need to change the CID driver accordingly, then finally move the Type 2 parsing routines to "psaux" when appropriate..
Werner Lemberg e72c9fec 2000-07-31T18:59:02 Simplifying the FIELD_* and FRAME_* macros. Before calling these macros, you should #define FT_STRUCTURE to the structure which will be filled. Replaced FT_FIELD_REF with FT_FIELD_SIZE, FT_FIELD_SIZE_DELTA, and FT_FIELD_OFFSET to make the code more readable; additionally, it should be more portable because we no longer cast a pointer to an FT_UShort (which e.g. fails with Sun's C++ compiler) but computes the difference between two pointers which is guaranteed to work. Fixing warnings (and C++ errors) while using Sun's latest cc and CC incarnations. Most of them are related to variable shadowing.
Werner Lemberg c3dd151b 2000-07-26T14:11:15 autohint: Formatting. Replacing many enums with #defines since we do arithmetics (especially ORing which would produce undefined enum values). The ideal thing instead of #defines is `const int' as provided in C++... Adding header files to rules.mk
David Turner c49f69cb 2000-07-20T03:44:50 some welcome fixes related to the auto-hinter: - removed a stupid memory leak - fixed the weird metrics hinting (the horizontal edges were used, instead of the vertical one, to compute the metrics adjustments, silly, silly, silly). there is still some bugs that I'm looking at though, but we're very near the release..
David Turner 3469d0d0 2000-07-19T20:02:14 added auto-hinter module. Note that the code has been cleaned up, and it seems a bug was introduced ??? I'll start checking this under Linux, as debugging is a lot easier under this environment..
