5e094c6f | 2013-06-10 14:59:21 | [truetype] Improve handling of broken sbit advance widths. * src/truetype/ttgload.c (TT_Load_Glyph): Use the glyph's (scaled) `linearHoriAdvance' if the sbit's `horiAdvance' value is zero. Cf. font `Fixedsys Excelsior' v3.01 (FSEX300.ttf), glyph A, 16ppem. | |
|
a25ecfdd | 2013-06-10 12:57:16 | [sfnt] Improve embedded bitmap tracing. * src/base/ftobjs.c (FT_Request_Size): Move trace message regarding bitmap strike match to... (FT_Match_Size): This function. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics, tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_png, tt_sbit_decoder_load_image): Decorate with tracing messages. | |
|
99e60d84 | 2013-06-10 01:44:37 | Fix Savannah bug #39160. * src/truetype/ttinterp.c (Ins_SDPVTL): Set projection vector too for the degenerate case. | |
|
2ba871b2 | 2013-06-09 08:20:54 | * src/cache/ftcmanag.c (FTC_Manager_Reset): Add missing cache flush. This code, present since eight(!) years in the unused `CACHE' branch, has been forgotten to apply to the master branch. It's really amazing that noone has ever complained since `FTC_Manager_Reset' is pretty useless without flushing the cache. | |

|
dc624ca4 | 2013-06-04 10:30:48 | Apply fixes for cppcheck nitpicks. http://cppcheck.sourceforge.net/ Note that the current version heavily chokes on FreeType, delivering even wrong results.

|
2429dc3d | 2013-06-03 12:41:58 | Add CFF_CONFIG_OPTION_OLD_ENGINE configuration option. This controls whether the old FreeType CFF engine gets compiled into FreeType.

 |
760d342d | 2013-05-29 11:36:18 | Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng.

77c39b1d | 2013-05-04 18:04:07 | [cff] Make Adobe CFF engine work correctly on 64bit hosts. Reported by numerous people on the `freetype-devel' list. Without this fix, glyphs aren't properly aligned on a common baseline. On 64bit systems, `FT_Pos' expands to `long int', having a width of 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on 64bit hosts also. Wrong casts filled up the blues arrays with incorrect values. Note that all blues values are accessed with the `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion. * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for `data', not `CF2_Fixed'. * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues, cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated. * src/cff/cf2blues.c (cf2_blues_init): Updated. | |

06474c3e | 2013-04-13 18:53:28 | [cff] Add a new Type 2 interpreter and hinter. This work, written by Dave Arnold <darnold@adobe.com> and fully integrated into FreeType by me, is a donation by Adobe in collaboration with Google. It is vastly superior to the old CFF engine, and it will replace it soon. Right now, it is still off by default, and you have to explicitly select it using the new `hinting-engine' property of the cff driver. For convenience, (most of) the new files are committed separately. * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro. * include/freetype/ftcffdrv.h: New file to access CFF driver properties. * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error code. * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints', and `cf2interp'. * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'. * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine' and `no_stem_darkening'. * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'. * src/cff/cff.c: Include new files. * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle `hinting-engine' and `no-stem-darkening' properties (only the Adobe engine listens to them). * src/cff/cffgload.c: Include `cf2ft.h'. (cff_decoder_prepare): Initialize `current_subfont'. (cff_build_add_point): Handle Adobe engine which uses 16.16 coordinates.

706fc833 | 2013-03-17 08:09:17 | Remove dead code. * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init) src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it. | |
|
8b4459b8 | 2013-03-17 07:44:35 | * src/pshinter/pshpic.h (GET_PIC): Use correct container. | |
|
89f50647 | 2013-03-14 17:50:49 | */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code. | |
|
e3c93015 | 2013-03-14 11:21:17 | */*: Use FT_Err_Ok only. This is a purely mechanical conversion. | |
|
059bc335 | 2013-03-14 10:27:35 | */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. | |
|
c58ce3be | 2013-03-13 11:06:39 | Introduce `FT_THROW' macro. The idea is to replace code like return FT_Err_Foo_Bar; or return CFF_Err_Foo_Bar; with return FT_THROW( Foo_Bar ); The FT_THROW macro has two functions: . It hides the module specific prefix. . In debug mode, it calls the empty function `FT_Throw' which can be thus used to set a breakpoint. * include/freetype/internal/ftdebug.h (FT_THROW): New macro. (FT_Throw): New prototype. * src/base/ftdebug.c (FT_Throw): New function. | |
|
dbc6e3f1 | 2013-03-12 11:42:20 | Remove `FT_KEEP_ERR_PREFIX'. The idea is to always have FT_ERR_PREFIX available internally. * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard undefinition of FT_ERR_PREFIX * src/gxvalid/gxverror.h, src/otvalid/otverror.h, src/sfnt/sferrors.h: Updated. | |
|
c879f245 | 2013-03-11 10:11:57 | [gxvalid] Fix module error. * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as FT_Mod_Err_GXvalid. * include/freetype/ftmoderr.h: Add module error for `GXvalid'. | |
|
d6bc524b | 2013-03-11 09:50:53 | Always use module related error codes. * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use `FT_ERROR_BASE'. * src/type1/t1load.c (parse_encoding): Use T1_Err_Unknown_File_Format. | |
|
2d882540 | 2013-03-08 21:23:45 | [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also. * src/cff/cffgload.c (cff_slot_load): Implement it. | |
 |
2ba18ba1 | 2013-02-22 23:58:57 | [base] Fix commit ab02d9e8. * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22. | |
|
f9434dba | 2013-02-19 21:27:18 | [base] New bisecting BBox_Cubic_Check (disabled). * src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm for extremum search built around simple condition that defines which half contains the extremum. | |
|
0e536676 | 2013-02-18 20:41:56 | [tools] Update BBox testing tool. * src/tools/test_bbox.c: Add another cubic outline with exact BBox. (REPEAT): Increase the number of benchmarking cycles. (profile_outline): Tweak output formatting. | |
|
a2c7eb18 | 2013-02-07 19:49:12 | * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables. BTW, Greg agrees that the OpenType specification is missing the list of GS variables which will always be reset to the default values after the `prep' table has been executed. | |
|
bfcc375b | 2013-02-06 08:47:29 | * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points. Up to now, we simply took a snapshot of the Graphics State after the `prep' table has been executed, and right before a glyph's bytecode was run it got reloaded. However, as Greg Hitchcock has told us in private communication, reference points get reset to zero in the MS rasterizer and we follow in due course. While reasonable, this is undocumented behaviour. Most notably, this fixes the rendering of Arial's `x' glyph in subpixel hinting mode. | |
|
00dfa330 | 2013-02-05 19:23:16 | [truetype] A better fix for Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Implement identical behaviour to MS rasterizer if rp1 == rp2 (confirmed by Greg Hitchcock). | |
|
0eb6316f | 2013-02-01 20:24:00 | [pcf] Streamline parsing of PCF encoding table. * src/pcf/pcfread.c (pcf_get_encodings): Use simpler double for-loop. Reallocate array instead of using temporary storage. | |
|
30f1e6ca | 2013-02-01 14:50:08 | Fix Savannah bug #38221. This complements commit 83c0ebab. * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with `TT_USE_BYTECODE_INTERPRETER'. | |
|
40633205 | 2013-02-01 12:55:44 | [truetype] Fix Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical to other interpreters if rp1 == rp2 (which is invalid). | |

|
f41ee054 | 2013-01-25 16:41:24 | Fix Savannah bug #38167. This fixes commit 83c0ebab from 2012-06-27. * src/truetype/ttinterp.h: s/TT_CONFIG_OPTION_BYTECODE_INTERPRETER/TT_USE_BYTECODE_INTERPRETER/. | |
 |
ba931be2 | 2013-01-25 00:57:09 | [sfnt] Fix broken pointer overflow checks. Many compilers such as gcc and clang optimize away pointer overflow checks `p + n < p', because pointer overflow is undefined behavior. Use a safe form `n > p_limit - p' instead. Also avoid possible integer overflow issues, for example, using `num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2' given a large `num_glyphs'. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_image): Implement it. | |
|
817caa9f | 2013-01-25 00:40:56 | Fix `make multi' * src/base/ftoutln.c, src/base/fttrigon.c: Include FT_INTERNAL_CALC_H. | |

Include FT_TRIGONOMETRY_H. * src/truetype/ttgload.c: Don't include FT_TRIGONOMETRY_H. | |
|
87dc86d6 | 2013-01-24 08:39:43 | [truetype] Revert change from 2013-01-22. FreeType's `height' value is the baseline-to-baseline distance... * src/truetype/ttobjs.c (tt_size_reset): Undo. | |
|
b6de8e66 | 2013-01-23 23:31:41 | [base, truetype] New internal FT_Hypot function. * include/freetype/fttrigon.h (FT_Hypot): Declare it. * src/base/fttrigon.c (FT_Hypot): Define it. * src/truetype/ttgload.c (TT_Process_Composite_Component): Use it instead of explicit expressions. * src/truetype/ttinterp.c (Current_Ratio, Normalize): Use it instead of TT_VecLen. (TT_VecLen): Removed. | |

da11e5e7 | 2013-01-23 20:11:40 | [base] Fix integer overflow. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Normalize incoming and outgoing vectors and use fixed point arithmetic. | |
|
e1a2ac19 | 2013-01-23 19:51:28 | [base] Fix integer overflow. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Scale the coordinates down to avoid overflow. | |
|
869fb8c4 | 2013-01-23 19:43:28 | [base] Split out MSB function. * src/base/fttrigon.c (ft_trig_prenorm): Borrow from here. * include/freetype/internal/ftcalc.h (FT_MSB): Declare here. * src/base/ftcalc.c (FT_MSB): Define here. | |
|
e0469372 | 2013-01-22 11:07:07 | [truetype] Fix font height. * src/truetype/ttobjs.c (tt_size_reset): The Windows rendering engine uses rounded values of the ascender and descender to compute the TrueType font height. | |
|
71900980 | 2013-01-16 20:08:35 | Minor. | |
|
cd3f871e | 2013-01-16 19:56:08 | [sfnt] Fix optimized sbit loader. It was not taking bit_depth into consideration when blitting! * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_byte_aligned, * tt_sbit_decoder_load_bit_aligned): Handle bit depth. | |
 |
3a406127 | 2013-01-16 19:48:31 | [truetype] Improve sub-pixel code. This patches fixes many issues with the ttsubpix implementation. 1. Data tables are defined, instead of declared, in the header, and thus copied into each source file that includes it. 2. These tables were defined as global, mutable, visible variables, and thus costing private RAM to every process that loads the library (> 50 KB / process, this is huge!). Additionally, this also made the library export the symbols completely needlessly. 3. Missing `sph_' and `SPH_' prefixes to some of the definitions. Note that this doesn't try to fix the incredibly inefficient storage format for the data tables used by the code. This one will require another pass in the future. * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS): Renamed to... (SPH_MAX_NAME_SIZE, SPH_MAX_CLASS_MEMBERS): This. Update all users. (SPH_TweakRule, SPH_ScaleRule): Decorate with `const' where appropriate. (Font_Class): Rename to... (SPH_Font_Class): This. Decorate with `const' where appropriate. * src/truetype/ttsubpix.h (scale_test_tweak, sph_test_tweak): Decorate arguments with `const' where appropriate. Move font tweaking tables to... * src/truetype/ttsubpic.c: This file and decorate them with `static' and `const' where appropriate. (X_SCALING_Rules, X_SCALING_RULES_SIZE): Renamed to... (spu_X_SCALING_Rules, SPH_X_SCALING_RULES_SIZE): This. Update all users. | |

0e0fdc5d | 2013-01-12 23:05:55 | [truetype] Improve accuracy of normalization of short vectors. Unit vector components are stored as 2.14 fixed-point numbers. In order to calculate all 14 bits accurately, a short vector to be normalized has to be upscaled to at least 14 bits before its length is calculated. This has been safe since accurate CORDIC algorithms were adopted. * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000. | |
|
081aba39 | 2013-01-12 22:36:37 | [truetype] Kill very old vector normalization hacks. Back in the days, vector length calculations were not very accurate and the vector normalization function, Normalize, had to meticulously correct the errors for long vectors [commit b7ef2b096867]. It was no longer necessary after accurate CORDIC algorithms were adopted, but the code remained. It is time to kill it. * src/truetype/ttinterp.c (Normalize): Remove error compensation. (TT_VecLen): Remove any mention of old less accurate implementation. | |
|
a692170a | 2013-01-12 19:17:05 | Call it fixed-point. | |

ad9d5c97 | 2013-01-10 22:29:07 | [base] Update the overflow protection bit. The recent optimizations of CORDIC iterations drastically reduce the expansion factor. The vector components with MSB of 29 are now safe from overflow. * src/base/fttrigon.c (FT_TRIG_SAFE_MSB): New macro. (ft_trig_prenorm): Use it and remove dead code. |
