2005-08-20 Chia I Wu <[email protected]> * src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of ttmetrics here. TrueType fonts with only sbits always have ttmetrics.valid set to false. * src/truetype/ttgload.c (TT_Load_Glyph): Check that ttmetrics is valid before loading outline glyph. * src/cache/ftcimage.c (FTC_INode_New): Fix a memory leak. 2005-08-20 Werner Lemberg <[email protected]> * src/sfnt/ttload.c (tt_face_load_metrics_header): Ignore missing `hhea' table for SFNT Mac fonts. Change based on a patch by [email protected]. 2005-08-20 Masatake YAMATO <[email protected]> * src/otvalid/otvmod.c (otv_validate): Use ft_validator_run instead of ft_setjmp. 2005-08-19 Werner Lemberg <[email protected]> * src/truetype/ttgload.c (load_truetype_glyph): Fix compiler warnings. 2005-08-16 Chia I Wu <[email protected]> * src/truetype/ttinterp.c, src/truetype/ttinterp.h: Update copyright messages. 2005-08-16 Chia I Wu <[email protected]> * src/truetype/ttinterp.c, src/truetype/ttinterp.h: Remove original TT_Done_Context and rename TT_Destroy_Context to TT_Done_Context with slight changes. Update all callers. (TT_New_Context): Now takes TT_Driver argument directly. Update all callers. * src/truetype/ttobjs.h (tt_slot_init): New function. * src/truetype/ttobjs.c (tt_driver_init): Initialize execution context here. (tt_slot_init): New function to create extra points for the internal glyph loader. We then use it directly, instead of face's glyph loader, when loading glyph. * src/truetype/ttdriver.c (tt_driver_class): Use tt_slot_init for glyph slot initialization. (Load_Glyph): Load flag dependencies are handled here. Return error if size is NULL. * src/truetype/ttgload.c: Heavy cleanup and refactoring. (org_to_cur): Removed. (TT_Load_Simple_Glyph): Call FT_GlyphLoader_CheckPoints. (TT_Hint_Glyph): New funcion to hint a zone, prepared by caller. (TT_Process_Simple_Glyph): s/load/loader/. Use loader->pp values instead of recalculation. Use TT_Hint_Glyph. No need to save/restore loader->stream before and after TT_Vary_Get_Glyph_Deltas now. (TT_LOADER_SET_PP): New macro to calculate and set the four phantom points. (load_truetype_glyph): Never set exec->glyphSize to 0. This closes Savannah bug #13107. Forget glyph frame before calling TT_Process_Simple_Glyph. Use TT_LOADER_SET_PP. Scale all four phantom points. Split off some functionality to ... (TT_Process_Composite_Component, TT_Process_Composite_Glyph): These new functions. (TT_Load_Glyph): Set various fields of `glyph' here, not in load_truetype_glyph and compute_glyph_metrics. Split off some functionality to ... (load_sbit_image, tt_loader_init): These new functions. (compute_glyph_metrics): Call FT_Outline_Get_CBox. 2005-08-08 Werner Lemberg <[email protected]> * docs/INSTALL.ANY: Updated. 2005-08-05 Werner Lemberg <[email protected]> * src/cff/cffgload.c (cff_builder_close_contour), src/psaux/psobjs.c (t1_builder_close_contour): Protect against zero `outline' pointer. * src/base/ftgloadr.c (FT_GlyphLoader_Add): Protect against zero `loader' address. 2005-08-03 Werner Lemberg <[email protected]> * src/sfnt/sfdriver.c (sfnt_interface) [FT_OPTIMIZE_MEMORY]: Reactivate pointers to tt_find_sbit_image and tt_load_sbit_metrics to make X work again. 2005-08-02 Werner Lemberg <[email protected]> * src/otvalid/otvcommn.h: Remove dead code. 2005-07-31 Chia I Wu <[email protected]> * src/truetype/ttobjs.h (tt_size_run_fpgm, tt_size_run_prep): New functions. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): New functions. (tt_size_init): Add 4, instead of 2, (phantom) points to twilight zone. Move code that runs fpgm to tt_size_run_fpgm. (Reset_Outline_Size): Move code that runs prep to tt_size_run_prep. (tt_glyphzone_new): Allocate right size of arrays. Set max_points and max_contours properly. 2005-07-26 Chia I Wu <[email protected]> * src/truetype/ttdriver.c (Set_Char_Sizes): Avoid unnecessary computations and clean up. * src/truetype/ttobjs.h (struct TT_SizeRec_): Comment on the internal copy of metrics. 2005-07-12 Werner Lemberg <[email protected]> * include/freetype/ftoutln.h (FT_Outline_Embolden): Fix prototype. Reported by Xerxes. 2005-07-04 Werner Lemberg <[email protected]> * include/freetype/internal/ftmemory.h (FT_REALLOC_ARRAY): Fix typo. Reported by Brett Hutley. 2005-06-30 David Turner <[email protected]> * src/sfnt/ftbitmap.c, src/truetype/ttgload.c, src/sfnt/ttcmap.c: Removing compiler warnings (Visual C++ /W4). Implement a work-around for broken C preprocessor in Visual C++ (it has been confirmed by the MS developers that it is indeed a bug which won't be fixed in the very near future). * Jamfile (FT2_COMPONENTS): Include otvalid (again). * src/otvalid/otvcommn.h (OTV_NAME, OTV_FUNC): New macros. (OTV_NEST1, OTV_NEST2, OTV_NEST3): Use OTV_NAME and OTV_FUNC to avoid argument expansion by argument prescan. Append `Func' to all affected macros and change them to take just a single argument. Example: `AttachList' is renamed to `AttachListFunc'. * src/otvalid/otvgdef.c, src/otvalid/otvgpos.c, src/otvalid/otvgsub.c, src/otvjstf.c: Append `Func' to macros affected by the changes to OTV_NESTx and modify them to take just a single argument. 2005-06-20 Chia I Wu <[email protected]> * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: New function ft_glyphslot_grid_fit_metrics. * src/truetype/ttgload.c (compute_glyph_metrics): Use ft_glyphslot_grid_fit_metrics. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Use ft_glyphslot_grid_fit_metrics. FT_Outline_Get_CBox is called twice. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Modify metrics to more reasonable values when emboldening outline glyphs. The theoretic ones are unrealistic. 2005-06-16 Chia I Wu <[email protected]> * src/base/ftoutln.c (FT_Outline_Embolden): Strength should be halved. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Change the default strength. Don't increase slot->advance.y. 2005-06-16 Werner Lemberg <[email protected]> * include/freetype/freetype.h (FREETYPE_MINOR): Set to 2. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.ac (version_info): Set to 9:9:3. Currently, we are still binary compatible. * builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj: s/219/2110/, s/2.1.9/2.1.10/. * builds/freetype.mk (refdoc), README, Jamfile (RefDoc): s/2.1.9/2.1.10/. * docs/CHANGES, docs/VERSION.DLL: Updated. * ChangeLog: Split off older entries into... * ChangeLog.20, ChangeLog.21: These new files. 2005-06-15 Kirill Smelkov <[email protected]> The next release will be 2.2.0, so don't worry about source code backwards compatibility. * include/freetype/ftimage.h (FT_Outline_MoveToFunc, FT_Outline_LineToFunc, FT_Outline_ConicToFunc, FT_Outline_CubicToFunc, FT_SpanFunc, FT_Raster_RenderFunc), include/freetype/ftrender.h (FT_Glyph_TransformFunc, FT_Renderer_RenderFunc, FT_Renderer_TransformFunc): Decorate parameters with `const' where appropriate. 2005-06-15 Chia I Wu <[email protected]> * src/sfnt/ttsbit.c (tt_face_load_sbit_image): Compute vertBearingY to make glyphs centered vertically. * src/truetype/ttgload.c (compute_glyph_metrics): Compute vertBearingY to make glyphs centered vertically. Fix some bugs in vertical metrics: . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font units. . As we use the glyph's cbox to calculate the top bearing now there iss no need to adjust `top'. 2005-06-15 Werner Lemberg <[email protected]> * src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be in sync with OTV_OPTIONAL_OFFSET. Reported by YAMATO Masatake. 2005-06-13 Werner Lemberg <[email protected]> * docs/release: Update.
