Werner Lemberg 6da023d1 2010-05-20T15:38:00 TrueType: Make FreeType ignore maxSizeOfInstructions in `maxp'. Acroread does the same. * src/truetype/ttgload.c (TT_Process_Composite_Glyph): Call `Update_Max' to adjust size of instructions array if necessary and add a rough safety check. (load_truetype_glyph): Save `loader->byte_len' before recursive call. * src/truetype/ttinterp.h, src/truetype/ttinterp.c (Update_Max): Declare it as FT_LOCAL.

Chris Liddell 10cf3887 2010-02-18T17:09:30 Fix Savannah bug #28905. Initialize phantom points before calling the incremental interface to update glyph metrics. * src/truetype/ttgload.c (tt_get_metrics_incr_overrides) [FT_CONFIG_OPTION_INCREMENTAL]: New function, split off from... (tt_get_metrics): This. Updated. (load_truetype_glyph): Use tt_get_metrics_incr_overrides.
Ken Sharp 980b76ea 2010-02-10T07:02:43 Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of *one* direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it.

Werner Lemberg 3445e4f9 2010-01-04T15:53:27 Make incremental interface work with TrueType fonts. * src/truetype/ttgload.c (load_truetype_glyph): Don't check `glyf_offset' if incremental interface is used.
Werner Lemberg 9045f5bd 2009-12-03T05:57:30 Fix compiler warnings. * src/truetype/ttgload.c (tt_get_metrics): Put `Exit' label into the proper preprocessor conditional. * src/pfr/pfrobjs.c (pfr_slot_load): Pacify gcc.

Werner Lemberg c0aeef45 2009-11-08T07:58:05 Fix compiler warning. Reported by Jeremy Manson <jeremy.manson@gmail.com>. * src/truetype/ttgload.c (load_truetype_glyph): Initialize `error'.
Werner Lemberg f186ba68 2009-11-03T15:46:35 Return correct `linearHoriAdvance' value for embedded TT bitmaps too. Reported by Jeremy Manson <jeremy.manson@gmail.com>. src/truetype/ttgload.c (load_truetype_glyph): Add parameter to quickly load the glyph header only. Update all callers. (tt_loader_init): Add parameter to quickly load the `glyf' table only. Update all callers. (TT_Load_Glyph): Compute linear advance values for embedded bitmap glyphs too.

Bram Tassyns 4694ea2b 2009-09-02T13:06:33 Improve vertical metrics calculation (Savannah bug #27364). The calculation of `vertBearingX' is not defined in the OTF font spec so FreeType does a `best effort' attempt. However, this value is defined in the PDF and PostScript specs, and that algorithm is better than the one FreeType currently uses: FreeType: Use the middle of the bounding box as the X coordinate of the vertical origin. Adobe PDF spec: Use the middle of the horizontal advance vector as the X coordinate of the vertical origin. FreeType's algorithm goes wrong if you have a really small glyph (like the full-width, circle-like dot at the end of the sentence, as used in CJK scripts) with large bearings. With the FreeType algorithm this dot gets centered on the baseline; with the PDF algorithm it gets the correct location (in the top right). Note that this is a serious issue, it's like printing the dot at the end of a Roman sentence at the center of the textline instead of on the baseline like it should. So i believe the PDF spec's algorithm should be used in FreeType as well. The `vertBearingY' value for such small glyphs is also very strange if no `vmtx' information is present, since the height of the bbox is not representable for the height of the glyph visually (the whitespace up to the baseline is part of the glyph). The fix also includes some code for a better estimate of `vertBearingY'. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Estimate for `vertBearingY' now works better for small glyphs completely above or below the baseline into account. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Vertical metrics information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS was not defined. * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec.
suzuki toshiya 9206eba2 2009-08-01T00:32:17 truetype: Truncate the deltas of composite glyph at 16-bit values.
suzuki toshiya 1b6f1d20 2009-08-01T00:32:16 truetype: Truncate the instructions upto 16-bit per a glyph.
suzuki toshiya 9fc40943 2009-08-01T00:32:14 truetype: Cast the scaling params to 32-bit for LP64 system.
Werner Lemberg 858abbed 2009-06-26T06:15:41 For warning messages, replace FT_ERROR with FT_TRACE0. FT_ERROR is now used only if a function produces a non-zero `error' value. Formatting, improving and harmonizing debug strings.
Werner Lemberg 72271140 2009-06-18T15:42:52 Fix B/W rasterization of subglyphs with different drop-out modes. Normally, the SCANMODE instruction (if present) to set the drop-out mode in a TrueType font is located in the `prep' table only and thus valid for all glyphs. However, there are fonts like `pala.ttf' which additionally contain this instruction in the hinting code of some glyphs (but not all). As a result it can happen that a composite glyph needs multiple drop-out modes for its subglyphs since the rendering state gets reset for each subglyph. FreeType collects the hinted outlines from all subglyphs, then it sends the data to the rasterizer. It also sends the drop-out mode -- after hinting has been applied -- and here is the error: It sends the drop-out mode of the last subglyph only; drop-out modes of all other subglyphs are lost. This patch fixes the problem; it adds a second, alternative mechanism to pass the drop-out mode: For each contour, the rasterizer now checks the first `tags' array element. If bit 2 is set, bits 5-7 contain the contour's drop-out mode, overriding the global drop-out mode. * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro. * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in `tags[0]'. * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom): Use bits 3-5 instead of 0-2. (New_Profile): Set the drop-out mode in the profile's `flags' field. (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if necessary. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out mode.
Werner Lemberg 780d7e05 2009-06-17T06:45:20 Minor simplification.
Werner Lemberg 1474f439 2008-12-09T06:51:56 Really fix Savannah bug #25010: An SFNT font with neither outlines nor bitmaps can be considered as containing space `glyphs' only. * src/truetype/ttpload.c (tt_face_load_loca): Handle the case where a `glyf' table is missing. * src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no `glyf' table but a non-zero `loca' entry. (tt_loader_init): Handle missing `glyf' table. * src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05. * src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines nor bitmaps is scalable.
Werner Lemberg 35ae574a 2008-10-02T10:40:52 Add casts for stupid compilers. Reported by Graham.
David Turner 28534d61 2008-09-01T21:35:21 * include/freetype/ftadvanc.h, src/base/ftadvanc.c, include/freetype/config/ftheader.h, include/freetype/freetype.h, src/base/Jamfile, src/base/rules.mk, src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffgload.h, src/truetype/ttdriver.c, src/truetype/ttgload.h, src/truetype/ttgload.c, src/type1/t1driver.c, src/type1/t1gload.h, src/type1/t1gload.c: Add a new header named FT_ADVANCES_H declaring some new APIs to extract the advances of one or more glyphs without necessarily loading their outlines. Also provide 'fast loaders' for the TrueType, Type1 and CFF font drivers (more to come later) * autogen.sh: add checks for minimum version of the 'autotools' stuff.
Werner Lemberg 745a4f42 2008-06-22T22:41:24 * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff with IS_HINTED. * docs/CHANGES: Updated.
Werner Lemberg 5df5dbb7 2008-06-22T13:40:08 Enable access to the various dropout rules of the B&W rasterizer. Pass dropout rules from the TT bytecode interpreter to the rasterizer; temporarily this is enabled only if `USE_SCAN_CONVERSION_RULES' is defined. * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS, FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the OpenType specification. Fix mode 4 computation.

Werner Lemberg ffa49657 2008-05-25T12:43:57 * src/truetype/ttgload.c (load_truetype_glyph): Move initialization of the graphics state for subglyphs to... (TT_Hint_Glyph): This function. Hinting instructions for a composite glyph apparently refer to the just hinted subglyphs, not the unhinted, unscaled outline. This seems to fix Savannah bugs #20973 and (at least partially) #23310.
Werner Lemberg 89d64fa6 2008-05-17T20:06:13 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour glyphs correctly. Patch from Savannah bug #23277.
Werner Lemberg bf391cb8 2008-01-10T08:47:08 * src/truetype/ttgload.c (load_truetype_glyph): Handle the case where the number of contours in a simple glyph is zero (and which does contain an entry in the `glyf' table). This fixes Savannah bug #21990.
Werner Lemberg bd7e1c3c 2007-12-06T17:17:30 Pass options from one configure script to another as-is (not expanded). This is needed for options like --includedir='${prefix}/include'. * builds/unix/detect.mk, configure: Prevent argument expansion in call to the (real) `configure' script. * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if TT_USE_BYTECODE_INTERPRETER isn't defined. There exist CFFs which contain opcodes for the Type 1 operators `hsbw' and `closepath' which are both invalid in Type 2 charstrings. However, it doesn't harm to support them. * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and `cff_op_closepath.' (cff_argument_counts): Ditto. (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath) and 13 (hsbw) which are invalid in Type 2 charstrings.

Werner Lemberg 3033f436 2007-07-04T14:12:19 * src/truetype/ttgload.c (load_truetype_glyph): Always allow a recursion depth of 1. This was the maximum value in TrueType 1.0, and some older fonts don't set this field correctly. * src/gxvalid/gxvmort1.c (gxv_mort_subtable_type1_substTable_validate): Fix tracing message.
David Turner 0ba89912 2007-07-01T09:34:04 fix a small bug in the TrueType loader that created distortion in the result of bytecode-hinted text. Werner, feel free to package 2.3.5 now :-)

Werner Lemberg e12ed563 2007-06-17T05:31:23 * src/tools/ftrandom.c (font_size): New global variable. (TestFace): Use it. (main): Handle new option `--size' to set `font_size'. (Usage): Updated. Formatting.
David Turner 815911ae 2007-06-16T17:07:20 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): check the well-formedness of the contours array when loading a glyph * src/truetype/ttinterp.c (Ins_IP): check argument ranges to reject bogus operations properly
Werner Lemberg f6c120f8 2007-06-11T04:55:58 * docs/CHANGES: Document FT_Face_CheckTrueTypePatents). Formatting, reformulations.

Werner Lemberg 6f99c888 2007-05-19T07:01:49 * src/truetype/ttgload.c (load_truetype_glyph): Save graphics state before handling subglyphs so that it can be reinitialized each time. This fixes Savannah bug #19859.
Werner Lemberg d0692468 2007-05-16T15:48:02 Oops! Incorrect application of a patch...
Werner Lemberg 607dec79 2007-05-15T06:49:37 * src/autofit/afcjk.c (af_cjk_hints_compute_edges): Remove unused variable. * src/autofit/afloader.c (af_loader_load_g): Ditto. * src/base/ftobjs.c (ft_validator_error): Use `ft_jmp_buf'.

David Turner 384be234 2007-01-05T15:32:01 * src/truetype/ttobjs.h, src/truetype/ttobjs.c, src/truetype/ttgload.c: do not allocate interpreter-specific tables in memory if we're not going to load glyphs with it anyway.
Werner Lemberg 6b87e6f0 2007-01-02T19:20:08 * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): Remove compiler warning. Formatting.

David Turner 33f5f249 2006-08-16T16:50:55 * include/freetype/internal/ftgloadr.h, include/freetype/internal/tttypes.h, src/base/ftgloadr.c, src/base/ftobjs.c, src/truetype/ttgload.c, src/truetype/ttinterp.c, src/truetype/ttobjs.c: improvements to native TrueType hinting, this is a first try, controlled by the FIX_BYTECODE macro in src/truetype/ttinterp.c
David Turner 9fbfc6af 2006-08-16T09:11:31 * src/cid/cidgload.c (cid_slot_load_glyph), src/truetype/ttgload.c (tt_prepare_zone): removing compiler warnings
Werner Lemberg a2da05c2 2006-06-25T06:27:27 Fix two hinting bugs as reported in http://lists.nongnu.org/archive/html/freetype-devel/2006-06/msg00057.html. * include/freetype/internal/tttypes.h (TT_GlyphZoneRec): Add `first_point' member. * src/truetype/ttgload.c (tt_prepare_zone): Initialize `first_point'. (TT_Process_Composite_Glyph): Always untouch points. * src/truetype/ttinterp.c (Ins_SHC): Fix computation of `first_point' and `last_point' in case of composite glyphs. (Ins_IUP): Fix computation of `end_point'.
Werner Lemberg 545c4e56 2006-05-17T22:55:04 * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again. Formatting, documentation fixes.
David Turner 281679de 2006-05-17T13:34:21 * include/freetype/internal/tttypes.h, src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c, src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c, src/type1/t1gload.c: this is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glypn vector themselves and the auto-fitter. note that we've started using inline assembler with GCC to implement FT_MulFix, given that this function is so damn important for the engine's performance. the resulting speed-up is about 25%.
Wu, Chia-I (吳佳一) 9a2b3b6d 2006-02-14T08:37:03 * src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply return error if table is missing. Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'. * src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics tables. The last change makes Mac bitmap-only font not load and this fixes it. * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error when FT_CONFIG_OPTION_INCREMENTAL is defined.
Wu, Chia-I (吳佳一) f5aa47be 2006-02-14T06:40:10 Clean up the SFNT_Interface. Table loading functions are now named after the tables' tags; `hdmx' is TrueType-specific and thus the code is moved to the truetype module; `get_metrics' is moved here from the truetype module so that the code can be shared with the cff module. This pass involves no real changes. That is, the code is moved verbatim mostly. The only exception is the return value of `tt_face_get_metrics'. * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading and parsing code is moved here. Move `tt_face_get_metrics' here from the truetype module. The return value is changed from `void' to `FT_Error'. * include/freetype/internal/fttrace.h: New trace: ttmtx. * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and parsing code is moved here. New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'. `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. * src/cff/cffgload.c, src/cff/cffobjs.c: Update. * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

Werner Lemberg 3bfb1c08 2005-08-29T11:59:18 * src/truetype/ttgload.c [TT_MAX_COMPOSITE_RECURSE]: Removed. (load_truetype_glyph): Limit recursion depth by `maxComponentDepth'.
Werner Lemberg 2752bd1a 2005-08-22T07:11:31 * src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline to (0,0) if bit 1 of the `head' table isn't set. This improves rendering of buggy fonts.
Wu, Chia-I (吳佳一) 15c1f5d3 2005-08-20T08:17:44 * src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of ttmetrics 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: Use tt_slot_init for glyph slot initialization. (TT_Load_Glyph): Load flag dependencies are handled here. Return error if size is NULL. * src/truetype/ttgload.c: Heavy cleanup and refactor. (TT_Hint_Glyph): New funcion to hint a zone, prepared by caller. (TT_Process_Simple_Glyph): Use loader->pp's instead of recalculating. Use TT_Hint_Glyph. No need to save/restore loader->stream before/after TT_Vary_Get_Glyph_Deltas now. (TT_LOADER_SET_PP): New macro to calculate and set the four phantom points. (TT_Process_Composite_Component, TT_Process_Composite_Glyph, load_truetype_glyph): Refactor load_truetype_glyph into these three functions. Never set exec->glyphSize to 0. (close #13107) Forget glyph frame before calling TT_Process_Simple_Glyph. (TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into these three functions. Set various fields of `glyph' here, instead of in load_truetype_glyph and compute_glyph_metrics.
Werner Lemberg 8e3fc5ea 2005-08-03T21:17:53 * src/otvalid/otvcommn.h: Remove dead code. Formatting.

Werner Lemberg 07437dba 2005-07-13T06:56:08 * include/freetype/ftoutln.h (FT_Outline_Embolden): Fix prototype. Reported by Xerxes.
David Turner c5621628 2005-06-30T11:46:46 * src/sfnt/ftbitmap.c, src/truetype/ttgload.c, src/sfnt/ttcmap.c: removing compiler warnings (Visual C++ /W4) * Jamfile, src/otvalid/{otvcommn.h,otvgdef.c,otvgpos.c,otvgsub.c, otvjstf.c}: modified the code to use a different pre-processor trick to implement the OTV_NEST1, OTV_NEST2 and OTV_NEST3 macros. The code now compiles neatly with Visual C++. The 'otvalid' module has been put in the Jamfile build again.
Wu, Chia-I (吳佳一) 8cfb220e 2005-06-20T09:04:50 * 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.
Werner Lemberg 49f4d34e 2005-06-16T19:07:08 * 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. * 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. 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. * 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'. * src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be in sync with OTV_OPTIONAL_OFFSET. Reported by YAMATO Masatake. * docs/release: Update.
Werner Lemberg 8744edfe 2005-04-06T14:48:55 * src/truetype/ttgload.c (tt_face_get_metrics) [FT_OPTIMIZE_MEMORY]: Fix typo which sometimes causes wrong metrics for the last glyph.

Werner Lemberg f13516c8 2005-03-03T17:09:08 Various fixes for C and C++ compiling. * src/autofit/*: Add copyright messages. Formatting. * src/autofit/afhints.c (af_glyph_hints_done): Don't use `AF_Dimension' but `int' for loop counter. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Don't use `AF_Dimension' but `int' for loop counter. Use proper enumeration value for `render_mode'. (af_latin_metrics_scale_dim): Don't shadow variables. (af_latin_hints_compute_segments): Use proper cast for `major_dir' and `segment_dir'. (af_latin_align_linked_edge, af_latin_hint_edges): Fix arguments of call to `af_latin_compute_stem_width'. (af_latin_hints_apply): Don't use `AF_Dimension' but `int' for loop counter. * src/base/ftdbgmem.c (ft_mem_table_get_source, FT_DumpMemory): Use proper cast for memory allocation. * src/cff/cffdrivr.c (cff_get_kerning): Use proper cast for initialization of `sfnt'. * src/sfnt/sfdriver.c: Include `ttkern.h'. * src/sfnt/ttkern.c (tt_face_get_kerning): Don't shadow variables. * src/truetype/ttgload.c: Include `ttpload.h'. * src/truetype/ttpload.c (tt_face_load_loca) [FT_OPTIMIZE_MEMORY]: Remove redundant variable.

(FT_COMPONENT): Updated. * include/freetype/internal/fttrace.h: Add entry for `ttkern'. * src/sfnt/ttsbit0.c: s/FT_Err_/SFNT_Err_/. Decorate constants with `U' and `L' where necessary. * src/sfnt/ttcmap.c (tt_cmap4_next): Remove unused variable.
David Turner e5680279 2005-02-26T00:12:04 * many, many files: several memory optimizations were implemented to drastically reduce the heap usage of FreeType, especially in the case of memory-mapped files. The idea is to avoid loading and decoding tables in the heap, and instead access the raw data whenever possible (i.e. when it doesn't compromise performance). This had several impacts: first, opening vera.ttf uses a ridiculous amount of memory (when the FT_Library footprint is accounted for), until you start loading glyphs. Even then, you'll save at least 20 Kb compared to the non optimized case. performance of various operations, including open/close has also been dramatically improved. More optimisations to come. The auto-hinter eats memory like crazy? This must be stopped...
David Turner e70d5531 2005-02-22T16:53:06 * include/freetype/config/ftoption.h, include/freetype/internal/ttypes.h, src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c: added the temporary configuration FT_OPTIMIZE_MEMORY to control various optimizations used to reduce the heap footprint of memory-mapped TrueType files. * src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location, tt_face_done_loca): when FT_OPTIMIZE_MEMORY is set, the locations table is read directly from memory-mapped streams, instead of being decoded into the heap. * src/truetype/ttpload.c: only load the CVT and fpgm tables when the bytecode interpreter is compiled in.
Werner Lemberg b9ff415d 2004-11-19T10:35:52 Fix a serious bug in the TT hinter. * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Don't shift points vertically before hinting. * docs/CHANGES: Updated. * src/cache/ftcglyph.c (FTC_GNode_UnselectFamily, FTC_GCache_Lookup): A new try to fix comparison with zero.
Werner Lemberg 685dd4f7 2004-10-13T05:15:44 * src/sfnt/ttcmap.c (tt_face_build_cmaps): Check for pointer overflow. * src/sfnt/ttload.c (tt_face_load_hdmx): Protect against bad input. Don't use FT_QNEW_ARRAY but FT_NEW_ARRAY to make deallocation work in case of failure. * src/sfnt/ttsbit.c (Load_SBit_Range): Check range intervals. (tt_face_load_sbit_strikes): Allocate `strike_sbit_ranges' after frame test. * src/truetype/ttgload.c (TTLoad_Simple_Glyph): Add assertion for `flag'.
