| |
| [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. |
| |
| 2013-05-04 Werner Lemberg <wl@gnu.org> |
| |
| More fixes for clang's `sanitize' feature. |
| |
| * src/base/ftcalc.c (FT_DivFix): Use unsigned values for |
| computations which use the left shift operator and convert to signed |
| as the last step. |
| * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, |
| FT_Vector_Length, FT_Vector_Polarize): Ditto. |

| |
| * src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt, |
| cf2_fracToFixed): Avoid shifts of negative values. |
| (cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed, |
| unused. |
| |
| * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR, |
| default>: Use unsigned values for computations and convert to signed |

| |
| [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/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. |
| (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING |
| separately. |
| Choose rendering engine based on `hinting_engine' property. |
| * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe |
| engine. |
| * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H. |

| cff_builder_start_point, cff_builder_close_contour, |
| cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data, |
| cff_free_glyph_data): Make them FT_LOCAL. |
| |
| * src/cff/cffgload.h: Updated. |
| |
| 2013-04-12 Werner Lemberg <wl@gnu.org> |
| |
| Add output bitmap checksums. |
| |
| Use `FT2_DEBUG=bitmap:3' for tracing. |
| |
| * src/base/md5.c, src/base/md5.h: New files, taken from |
| |
| https://openwall.info/wiki/people/solar/software/public-domain-source-code/md5 |
| |

| * src/bdf/bdflib.c (_bdf_readstream): Thinko. |
| |
| 2013-03-31 Werner Lemberg <wl@gnu.org> |
| |
| * configure: Use egrep, not grep. |
| |
| Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>. |
| |
| 2013-03-29 Werner Lemberg <wl@gnu.org> |
| |
| * include/freetype/ftlcdfil.h: Add description of color filtering. |
| |
| Based on a contribution from Antti S. Lankila <alankila@bel.fi> |
| (Savannah bug #38607). |
| |
| 2013-03-23 Werner Lemberg <wl@gnu.org> |
| |
| [autofit] Minor. |
| |
| * src/autofit/afmodule.c (af_property_set): Typo. |
| (af_autofitter_init, af_autofitter_done): Use cast. |
| |
| 2013-03-21 Werner Lemberg <wl@gnu.org> |
| |
| * configure: Automatically test for `gmake' also. |
| |
| Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>. |
| |
| 2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de> |
| |
| Respect CONFIG_SHELL from the environment. |
| |
| Some large packages using FreeType have to use a broken (deficient) |
| /bin/sh. The configure scripts (as generated by Autoconf) are |
| clever enough to find a better shell and put that one into the |
| environment variable CONFIG_SHELL. If that environment variable is |
| already set the script skips the test and assumes to be already |
| running under a good shell. |
| |
| * builds/unix/detect.mk: Honour CONFIG_SHELL. |
| * builds/unix/unix-def.in (SHELL): Define. |
| |
| 2013-03-21 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah patch #7971. |
| |
| * configure: Handle MAKE environment variable also. |
| |
| 2013-03-17 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah bug #38538. |
| |
| * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c, |
| builds/wince/ftdebug.c (FT_Throw): Add function. |
| |
| 2013-03-17 Werner Lemberg <wl@gnu.org> |
| |
| [raster] 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. |
| |
| 2013-03-17 Werner Lemberg <wl@gnu.org> |
| |
| * src/pshinter/pshpic.h (GET_PIC): Use correct container. |
| |
| 2013-03-15 Werner Lemberg <wl@gnu.org> |
| |
| * include/freetype/ftmoderr.h: Fix commit from 2013-03-11. |
| |
| The previous version was not backward compatible. Reported by |
| Behdad. |
| |
| 2013-03-14 Werner Lemberg <wl@gnu.org> |
| |
| */*: 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. |
| |
| 2013-03-14 Werner Lemberg <wl@gnu.org> |
| |
| New error management macros. |
| |
| * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to... |
| * include/freetype/fttypes.h: ... this file. |
| (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New |
| macros. |
| |
| * include/freetype/freetype.h: Updated. |
| |
| 2013-03-14 Werner Lemberg <wl@gnu.org> |
| |
| */*: Use FT_Err_Ok only. |
| |
| This is a purely mechanical conversion. |
| |
| 2013-03-14 Werner Lemberg <wl@gnu.org> |
| |
| */*: 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. |
| |
| 2013-03-13 Werner Lemberg <wl@gnu.org> |
| |
| 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. |
| |
| 2013-03-12 Werner Lemberg <wl@gnu.org> |
| |
| 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. |
| |
| 2013-03-11 Werner Lemberg <wl@gnu.org> |
| |
| [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'. |
| |
| 2013-03-11 Werner Lemberg <wl@gnu.org> |
| |
| 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. |
| |
| 2013-03-08 Werner Lemberg <wl@gnu.org> |
| |
| [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also. |
| |
| Problem reported by Khaled Hosny <khaledhosny@eglug.org>. |
| |
| * src/cff/cffgload.c (cff_slot_load): Implement it. |
| |
| 2013-02-23 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [base] Fix commit ab02d9e8. |
| |
| * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22. |
| |
| 2013-02-19 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [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. |
| |
| 2013-02-18 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [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. |
| |
| 2013-02-02 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah bug #38235. |
| |
| * builds/unix/configure.raw: Don't generate `freetype-config' and |
| `freetype.pc'. |
| |
| * builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ, |
| build_libtool_libs, ft_version): New variables to be substituted. |
| (freetype-config, freetype.pc): New rules to generate those files. |
| |
| * builds/unix/freetype-config.in: Remove code for handling `rpath'. |
| The use of $rpath has been accidentally removed in a patch from |
| 2009-12-22, and apparently noone has missed it since. |
| Use `%' instead of `@' as a variable substitution marker. |
| Use quotes. |
| |
| * builds/unix/freetype.in: Use `%' instead of `@' as a variable |
| substitution marker. |
| Use quotes. |
| |
| 2013-02-07 Werner Lemberg <wl@gnu.org> |
| |
| * 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. |
| |
| 2013-02-06 Werner Lemberg <wl@gnu.org> |
| |
| * 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. |
| |
| 2013-02-05 Werner Lemberg <wl@gnu.org> |
| |
| [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). |
| |
| 2013-02-01 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [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. |
| |
| 2013-02-01 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah bug #38227. |
| |
| * builds/unix/freetype-config.in: Set LC_ALL. |
| |
| 2013-02-01 Werner Lemberg <wl@gnu.org> |
| |
| Fix Savannah bug #38221. |
| |
| This complements commit 83c0ebab. |
| |
| * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with |
| `TT_USE_BYTECODE_INTERPRETER'. |
| |
| 2013-02-01 Werner Lemberg <wl@gnu.org> |
| |
| [truetype] Fix Savannah bug #38211. |
| |
| * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical |
| to other interpreters if rp1 == rp2 (which is invalid). |
| |
| 2013-01-28 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [base] Small optimization of BBox calculation. |
| |
| * src/base/ftbbox.c (BBox_Cubic_Check): Use FT_MSB function in |
| scaling algorithm. |
| |
| 2013-01-26 Infinality <infinality@infinality.net> |
| |
| [truetype] Minor formatting fix. |
| |
| * src/truetype/ttinterp.c: Updated. |
| (DO_RS): Fix indentation. |
| |
| 2013-01-26 Infinality <infinality@infinality.net> |
| |

| |
| [truetype] Align more to ClearType whitepaper for sph. |
| |
| * include/freetype/internal/tttypes.h (TT_FaceRec): Add flags |

| [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'. |

| [truetype] Improve subpixel 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. |

| [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. |
| |

| |
| [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. |

| |
| [base] Improve trigonometric core. |
| |
| FreeType used to rely on a 24-step iteration CORDIC algorithm to |
| calculate trigonometric functions and rotate vectors. It turns out |
| that once the vector is in the right half-plane, the initial rotation |
| by 63 degrees is not necessary. The algorithm is perfectly capable |
| to converge to any angle starting from the second 45 degree rotation. |
| This patch removes the first rotation and makes it a 23-step CORDIC |
| algorithm. |

| * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro |

| Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has |

| |
| [truetype] Scale F_dot_P down. |
| |
| The dot product between freeVector and projVector or cosine of |
| the angle between these FT_F2Dot14 unit vectors used to be scaled up |
| by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P. |
| This patch scales the value down by 2^14 instead, which simplifies |
| its use throughout the bytecode interpreter. |
| |
| This does not lead to the loss of precision because the lower bits |
| are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8) |
| for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. |
| These vectors are stored as (0x4000,0) and (0x2666,0x3333) after |
| rounding and F_dot_P is assigned 0x26660000. The lower bits were |
| already lost while rounding the unit vector components. |
| |
| Besides code simplification, this change can lead to better |
| performance when FT_MulDiv with the scaled-down F_dot_P is less |
| likely to use the costly 64-bit path. We are not changing the type |
| of F_dot_P to FT_F2Dot14 at this point. |
| |
| * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 |
| bits and modify its use accordingly. |
| (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify |
| the use of F_dot_P field. |
| * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary |
| assignment of F_dot_P to its theoretical maximum in case we decide |
| to scale back its type later. |

| |
| which addresses various enhancements of the auto-hinter. Without |
| properties to control a module's metadata it wasn't possible to |

| environment variables which I consider not suitable in general. |

| Fix `checking if gcc static flag -static works' test. |
| |
| On my linux build tree, I receive yes answer in every package I |
| build except FreeType for this test checking if gcc static flag |
| `-static' works |
| |
| In FreeType, no is received, unless bzip2 and zlib are disabled using |
| |
| ./configure --without-bzip2 --without-zlib |
| |
| The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to |
| LDFLAGS and this broke static flag test. |
| |
| * builds/unix/configure.raw: Update CFLAGS and LDFLAGS only after |
| LT_INIT has run. |

| |
| [truetype] Remove unused rounding functionality. |
| |
| The subpixel hinting patch contained the concept of an adjustable |
| number of gridlines per pixel. This is no longer used due to x |
| being completely ignored instead. This will return some of the |
| code to its existing state prior to the original Infinality |
| commit. |
| |
| * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, |
| FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): Removed. |

| Ins_MDRP, Ins_MIRP): Perform Round_None instead of calling a modified |
| rounding function. Remove gridlines_per_pixel. Create a local |
| variable to store control value cutin. Simplify the conditional for |
| ignore_x_mode. Adjust rounding calls to pass only two values. |

| |
| 2012-06-18 Infinality <infinality@infinality.net> |
| |
| [truetype] Support subpixel hinting. |
| |
| This is the large, famous `Infinality' patch to support ClearType |
| bytecode which has been available from |
| http://www.infinality.net/blog/ for some time, and which has been |
| refined over the last years. While still experimental, it is now |
| mature enough to be included directly into FreeType. |
| |
| Most of the code is based on the ClearType whitepaper written by |
| Greg Hitchcock |
| |
| https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx |
| |
| which gives a detailed overview of the necessary changes to the |
| Microsoft rasterizer so that older fonts are supported. However, a |
| lot of details are still missing, and this patches provides a |
| framework to easily handle rendering issues down to the glyph level |
| of certain fonts. |
| |
| Note that ClearType support is not completely implemented! In |
| particular, full support for the options `compatible_widths', |
| `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode |
| instruction) is missing. |
| |
| * src/truetype/ttsubpix.c: New file, providing code to handle |
| `tweaks', this is, rules for certain glyphs in certain fonts |
| (including wildcards) which need a special treatment. |
| |
| * src/truetype/ttsubpix.h: New file, holding the tweaking rules. |
| |
| * include/freetype/config/ftoption.h, src/devel/ftoption.h |
| (TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro. |
| |
| * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, |
| FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros. |
| |
| * src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include |
| `ttsubpix.c'. |
| |
| * src/truetype/ttgload.c: Include `ttsubpix.h'. |
| [All changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.] |
| |
| (tt_get_metrics): Set tweak flags. |
| (TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary. |
| (TT_Process_Simple_Glyph): Compensate emboldening if necessary. |
| (compute_glyph_metrics): Handle `compatible widths' option. |
| (tt_loader_init): Handle ClearType GETINFO information bits. |

| pixel. |

| [autofit] Return correct linear advance width values. |
| |
| This was quite a subtle bug which accidentally showed up with glyph |
| `afii10023' of arial.ttf (version 2.76). This glyph is a composite; |
| the first component, `E', has an advance width of 1366 font units, |
| while the advance width of the composite itself (which looks like |
| uppercase `E' with dieresis) is 1367 font units. I think this is |
| actually a bug in the font itself, because there is no reason that |
| this glyph has not the same width as uppercase `E' without the |
| dieresis. Anyway, it helped identify this problem. |
| |
| Using the TrueType hinter, the correct value (1367) of `afii10023' |
| was returned, but the autohinter mysteriously returned 1366. |
| |
| Digging in the code showed that the autohinter recursively calls |
| FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load |
| flag. However, the `linearHoriAdvance' field is still returned as a |
| scaled value. To avoid scaling twice, the old code in autofit reset |
| `linearHoriAdvance', using the `horiAdvance' field. This seemed to |
| work since FT_LOAD_NO_SCALE was in use, but it failed actually, |
| because `horiAdvance' is defined as the distance of the first |
| subglyph's phantom points, which in turn are initialized using the |
| advance width of the first subglyph. And as the given example |
| shows, these widths can differ. |
| |
| * src/autofit/afloader.c (af_loader_load_g): Temporarily set |
| FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled |
| values for the linear advance widths. |

| [truetype] Fix SSW instruction. |
| |
| * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units. For |

| this instruction. |

| |
| Fix redundant declaration warning in PIC mode. |
| |
| Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were |
| designed to declare xxx_pic_{free,init} by themselves. |
| Because these macros are used at the end of the module |
| interface (e.g. ttdriver.c) and the wrapper source to build |
| a module as a single object (e.g. truetype.c) includes |
| the PIC file (e.g. ttpic.c) before the module interface, |
| these macros are expanded AFTER xxx_pic_{free,init} body |
| when the modules are built as single object. |
| The declaration after the implementation causes the redundant |
| declaration warnings, so the declarations are moved to module |
| PIC headers (e.g. ttpic.h). Separating to other header files |
| are needed for multi build. |
| |
| * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER): |
| Remove class_##_pic_free and class_##_pic_init declarations. |
| * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER, |
| FT_DEFINE_MODULE): Ditto. |
| |
| * src/base/basepic.h: Insert a comment and fix coding style. |
| * src/autofit/afpic.h: Declare autofit_module_class_pic_{free, |

| [base] Fix a dereference of uninitialized variable in PIC mode. |
| |
| * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be |
| set before dereferring to obtain `library'. The initialization |
| of `clazz', `glyph', `library' and NULL pointer check are |
| reordered to minimize PIC conditionals. |
| |
| 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [base] Insert explicit cast for GCC 4.6 in PIC mode. |
| |
| * src/base/ftinit.c (FT_Add_Default_Modules): Under PIC |
| configuration, FT_DEFAULT_MODULES_GET returns |
| FT_Module_Class** pointer, GCC 4.6 warns that |
| const FT_Module_Class* const* variable is warned as |
| inappropriate to store it. To calm it, explicit cast is |
| inserted. Also `library' is checked to prevent the NULL |
| pointer dereference in FT_DEFAULT_MODULES_GET. |
| |

| |
| Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6. |

| take no arguments but derefer the variable named `library' |
| internally. |
| |
| * src/cff/cffdrivr.c (cff_get_interface): Declare `library' and |
| set it if non-NULL driver is passed. |
| * src/truetype/ttdriver.c (tt_get_interface): Ditto. |

| 2011-12-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH. |
| |
| Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON |
| was a configurable macro to disable Carbon-dependent code. Because |
| now configure script sets DARWIN_NO_CARBON by default and disables |
| Darwin & Carbon-dependent codes, these macros can be unified. |
| FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON |
| (defined by default) is removed, because DARWIN_NO_CARBON violates |
| FT_XXX naming convention of public macros, and a macro configured by |
| default is not portable for the building without configure (e.g. |
| make devel). |
| |
| * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based |
| old Mac font support is requested and Carbon is available. |
| * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support |
| for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is |
| requested. |
| * include/freetype/config/ftconfig.in: Ditto. |
| * builds/vms/ftconfig.h: Ditto. |

| * src/base/ftobjs.c: Ditto. |
| * src/base/ftrfork.c: Ditto. |
| |
| * src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined |
| (same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c). |
| * builds/mac/ftmac.c: Ditto. |
| |
| * builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH. |

| like systems without `init' nor `hurd' (e.g. Mac OS X >= 10.4). |
| * builds/unix/detect.mk: Ditto. |
| |
| 2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [apinames] Fix the overflow of signed integer hash. |
| |
| * src/tools/apinames.c (names_add): Change the type of `h' from |
| int to unsigned int, to prevent undefined behaviour in the |
| overflow of signed integers (overflow of unsigned int is defined |
| to be wrap around). Found by clang test suggested by Sean |
| McBride. |
| |

| |
| [bdf] Fix Savannah bug #34896. |
| |
| ENCODING now covers the whole Unicode range. |
| |
| Note, however, that this change is quite expensive since it |
| increases the size of three arrays by almost 400kByte in total. The |
| right fix is to replace the logic with something smarter. |
| Additionally, there exist very old BDFs for three-byte CCCII |
| encoding which exceeds the range of Unicode (another reason to have |
| a smarter logic). |
| |
| * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod' |
| arrays. |
| * src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array. |
| |
| 2011-11-27 Werner Lemberg <wl@gnu.org> |

| 2011-09-11 Tomas Hoger <thoger@redhat.com> |
| |
| Slightly improve LZW_CLEAR handling. |
| |
| * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>: |
| Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are |
| handled as clear codes. This also re-sets old_code and old_char to |
| predictable values, which is a little better than using `random' |
| ones if the code following LZW_CLEAR is invalid. |
| |
| 2011-09-11 Tomas Hoger <thoger@redhat.com> |
| |
| Add explicit LZW decompression stack size limit. |
| |
| Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is |
| constructed correctly. It's even less than that, see e.g. |
| libarchive code comment for a better size upper bound: |
| |
| http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121 |
| |
| This patch adds explicit stack size limit, enforced when stack is |
| realloced. |
| |
| An alternative is to ensure that code < state->prefix[code - 256] |
| when traversing prefix table. Such check is less efficient and |
| should not be required if prefix table is constructed correctly in |
| the first place. |
| |
| * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it. |
| |
| 2011-09-11 Tomas Hoger <thoger@redhat.com> |
| |
| Protect against loops in the prefix table. |
| |
| LZW decompressor did not sufficiently check codes read from the |
| input LZW stream. A specially-crafted or corrupted input could |
| create a loop in the prefix table, which leads to memory usage |
| spikes, as there's no decompression stack size limit. |
| |

| |
| [ftstroke] Major revision. |
| |
| The main problems |
| ----------------- |
| |
| o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter |
| joins (not bevel joins) were generated. Indeed, the meanings of |
| `miter' and `bevel' were incorrectly reversed (consistently) in |
| both the code and comments. |
| |
| o The way bevel joins were constructed (whether specified |
| explicitly, or created as a result of exceeding the miter limit) |
| did not match what is required for stroked text in PostScript or |
| PDF. |
| |
| The main fixes |
| -------------- |
| |
| o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. |
| |
| o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been |
| introduced to support PostScript and PDF miter joins. |
| |
| o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an |
| alias for FT_STROKER_LINEJOIN_MITER. |
| |
| Additionally, a variety of stroking errors have been fixed. These |
| would cause various artifacts (including points `at infinity'), |
| especially when stroking poor quality fonts. |
| |
| See |
| |
| https://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html |
| |
| for example documents. The FreeType stroker now produces results |
| very similar to that produced by GhostScript and Distiller for these |
| fonts. |
| |
| Other problems |
| -------------- |
| |
| The following problems have been resolved: |
| |
| o Inside corners could be generated incorrectly. Intersecting the |
| inside corner could cause a missing triangular area and other |
| effects. |
| |
| The intersection point can only be used if the join is between |
| two lines and both lines are long enough. The `optimization' |
| condition in `ft_stroker_inside' has been corrected; this |
| requires the line length to be passed into various functions and |
| stored in `FT_StrokerRec'. |
| |
| o Incorrect cubic curves could be generated. The angle |
| calculations in `FT_Stroker_CubicTo' have been corrected to |
| handle the case of the curve crossing the +/-PI direction. |
| |
| o If the border radius was greater than the radius of curvature of |
| a curve, then the negative sector would end up outside (not |
| inside) the border. This situation is now recognized and the |
| negative sector is circumnavigated in the opposite direction. |
| (If round line joins are being used, this code is disabled |
| because the line join will always cover the negative sector.) |
| |
| o When a curve is split, the arcs may not join smoothly (especially |
| if the curve turns sharply back on itself). Changes in |
| direction between adjacent arcs were not handled. A round |
| corner is now added if the deviation from one arc to the next is |
| greater than a suitable threshold. |
| |
| o The current direction wasn't retained if a the outline contained |
| a zero length lineto or a curve that was determined to be |
| `basically a point'. This could cause a spurious join to be |
| added. |
| |
| o Cubics with close control points could be mishandled. All eight |
| cases are now distinguished correctly. |
| |
| Other improvements |
| ------------------ |
| |
| o Borders for cubic curves could be too `flat'. |
| FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent |
| this. |
| |
| o The handling and use of movable points has been simplified a |
| little. |
| |
| o Various values are now computed only if the results are actually |
| needed. |
| |
| o The directions of the outer and inner borders have been swapped, |
| as recommended by Graham Asher. |

| [autofit] Add bluezones for CJK Ideographs. |
| |
| To remove extrema of vertical strokes of CJK Ideographs at |
| low resolution and make the top and bottom horizontal stems |
| aligned, bluezones for CJK Ideographs are calculated from |
| sample glyphs. At present, vertical bluezones (bluezones |
| to align vertical stems) are disabled by default. For detail, see |

| |
| [truetype] Always check the checksum to identify tricky fonts. |
| |
| Because some PDF generators mangle the family name badly, |
| the trickyness check by the checksum should be invoked always. |
| For sample PDF, see |

| added. |
| |
| 2011-04-21 Behdad Esfahbod <behdad@behdad.org> |

| Always ignore global advance. |
| |
| This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant, |

| [autofit] Blur CJK stems if too many to preserve their gaps. |
| |
| When there are too many stems to preserve their gaps in the |
| rasterization of CJK Ideographs at a low resolution, blur the |

| https://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html |
| https://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html |
| for details. |
| |
| * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of |
| the previous stem by `has_last_stem' and `last_stem_pos', and skip |
| a stem if the current and previous stem are too near to preserve |
| the gap. |

| |
| Fix reading of signed integers from files on 64bit platforms. |
| |
| Previously, signed integers were converted to unsigned integers, but |
| this can fail because of sign extension. For example, 0xa344a1eb |
| becomes 0xffffffffa344a1eb. |
| |
| We now do the reverse which is always correct because the integer |
| size is the same during the cast from unsigned to signed. |
| |
| * include/freetype/internal/ftstream.h, src/base/ftstream.c |
| (FT_Stream_Get*): Replace with... |

| |
| [truetype] Improve handling of stack underflow. |
| |
| * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, |

| [truetype] Fix handling of MIRP instruction. |
| |
| Thanks to Greg Hitchcock who explained the issue. |
| |
| * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with |

| |
| Fix ARM assembly code in include/freetype/config/ftconfig.h. |
| |
| * include/freetype/config/ftconfig.h (FT_MulFix_arm): |
| Copy the maintained code from builds/unix/ftconfig.in. |
| Old GNU binutils could not accept the reduced syntax |
| `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT, |
| `orr %0, %0, %2, lsl #16' is better. Reported by |
| Johnson Y. Yan. The bug report by Qt developers is |
| considered too. |

| 2011-01-15 Werner Lemberg <wl@gnu.org> |
| |
| [raster] Make bbox handling the same as with Microsoft's rasterizer. |
| |
| Right before B/W rasterizing, the bbox gets simply rounded to |
| integers. This fixes, for example, glyph `three' in font `Helvetica |
| Neue LT Com 65 Medium' at 11ppem. |
| |
| Thanks to Greg Hitchcock who explained this behaviour. |
| |
| * src/raster/ftrend1.c (ft_raster1_render): Implement it. |

| Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS. |
| |
| * builds/unix/configure.raw: Consider recent gcc-standard |
| flags to specify architecture in CFLAGS & LDFLAGS |
| harmonization. Requested by Savannah bug #32114, to |
| support multilib feature of BuildRoot SDK correctly. |
| |
| 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer. |

| |
| 2011-01-13 Werner Lemberg <wl@gnu.org> |
| |
| [raster] Reduce jitter value. |
| |
| This catches a rendering problem with glyph `x' from Tahoma at |
| 10ppem. It seems that the increase of the precision in the change |
| from 2009-06-11 makes a larger jitter value unnecessary. |
| |
| * src/raster/ftraster.c (Set_High_Precision): Implement it. |
| |
| 2011-01-13 Werner Lemberg <wl@gnu.org> |
| |
| [raster] Handle drop-outs at glyph borders according to Microsoft. |
| |
| If a drop-out rule would switch on a pixel outside of the glyph's |
| bounding box, use the right (or top) pixel instead. This is an |
| undocumented feature, but some fonts like `Helvetica Neue LT Com 65 |
| Medium' heavily rely on it. |
| |
| Thanks to Greg Hitchcock who explained this behaviour. |
| |
| * src/raster/ftraster.c (Vertical_Sweep_Drop, |
| Horizontal_Sweep_Drop): Implement it. |

| |
| [cache] Fix Savannah bug #31923, patch drafted by Harsha. |
| |
| When a node comparator changes the cached nodes during the |
| search of a node matching with queried properties, the |
| pointers obtained before the function should be updated to |
| prevent the dereference to freed or reallocated nodes. |
| To minimize the rescan of the linked list, the update is |
| executed when the comparator notifies the change of cached |
| nodes. This change depends previous change: |
| 38b272ffbbdaae276d636aec4ef84af407d16181 |
| |
| * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the |
| top node if the cached nodes are changed. |
| * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto. |
| |
| 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cache] Notice if a cache query induced the node list change. |
| |
| Some node comparators (comparing the cache node contents and the |
| properties specified by the query) can flush the cache node to |
| prevent the cache inflation. The change may invalidate the pointers |
| to the node obtained before the node comparison, so it should be |
| noticed to the caller. The problem caused by the cache node |
| changing is reported by Harsha, see Savannah bug #31923. |
| |
| * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument |
| `FT_Bool* list_changed' to indicate the change of the cached nodes |
| to the caller. |
| (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by |
| `_list_changed'. |
| (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed' |
| and update it when `FTC_Manager_FlushN' flushes any nodes. |
| |
| * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new |
| FTC_Node_CompareFunc type. |
| (ftc_gnode_compare): Ditto. |
| |
| * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use |
| TRUE/FALSE macros. |
| (ftc_basic_gnode_compare_faceid): New argument `FT_Bool* |
| list_changed' to indicate the change of the cache nodes (anyway, it |
| is always FALSE). |
| |
| * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use |
| TRUE/FALSE macros. |
| (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to |
| indicate the change of the cache nodes (anyway, it is always FALSE). |
| (ftc_cmap_node_remove_faceid): Ditto. |
| |
| * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to |
| `FTC_CACHE_TRYLOOP_END', because the result is not needed. |
| (FTC_Cache_Lookup): Watch the change of the cache nodes by |
| `list_changed'. |
| (FTC_Cache_RemoveFaceID): Ditto. |
| |
| * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use |
| TRUE/FALSE macros. |
| (ftc_gnode_compare): New argument `FT_Bool* list_changed' to |
| indicate the change of the cache nodes (anyway, it is always FALSE). |
| (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be |
| passed to `ftc_gnode_compare'. |
| * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. |
| |
| * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool* |
| list_changed' to indicate the change of the cache nodes, anyway. It |
| is updated by `FTC_CACHE_TRYLOOP'. |
| (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be |
| passed to `ftc_snode_compare'. |
| * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. |
| |
| 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'. |
| |
| * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd |
| argument `FTC_Cache cache' to fit FTC_Node_CompareFunc |
| prototype. |
| * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway, |
| `cache' is not used by its child `ftc_gnode_compare'. |
| |
| 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cache] Deduplicate the code to get the top node by a hash. |
| |
| There are several duplicated code fragments getting the top node |
| from a cache by a given hash, like: |
| |
| idx = hash & cache->mask; |
| if ( idx < cache->p ) |
| idx = hash & ( cache->mask * 2 + 1 ); |
| pnode = cache->buckets + idx; |
| |
| To remove duplication, a cpp-macro to do same work |
| `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined |
| configuration, non-`ftc_get_top_node_for_hash' is also introduced. |
| |
| * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare |
| and implement inlined version. |
| (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'. |
| * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined |
| version. |
| (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'. |
| (ftc_node_hash_link): Ditto. |
| (FTC_Cache_Lookup): Ditto. |
| |
| 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cache] inline-specific functions are conditionalized. |
| |
| * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for |
| inlined configuration. This function is a thin wrapper of |
| `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see |
| `nodecmp' argument). Under non-inlined configuration, |
| `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via |
| `FTC_Cache->clazz.node_compare'. |
| |
| * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. |
| * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for |
| `ftc_snode_compare'. |
| * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. |
| |
| 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cache] Correct a type mismatch under non-inlined config. |
| |
| * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup' |
| takes the node via a pointer `FTC_Node*', differently from cpp-macro |
| `FTC_CACHE_LOOKUP_CMP'. |
| |

| |
| Update Jamfile to include Bzip2 support. |

| |
| 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Update Symbian project files to include Bzip2 support. |
| |
| Currently, it provides `FT_Stream_OpenBzip2' that returns |

| |
| * builds/symbian/bld.inf: Include ftbzip2.h. |

| |
| Update pkg-config tools to reflect Bzip2 support. |
| |
| * builds/unix/freetype-config.in: Include `-lbz2' to |

| * builds/unix/freetype2.in: Ditto. |
| |
| 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro. |
| |
| SYSTEM_ZLIB is used to switch the builtin zlib source |
| or system zlib source out of FreeType2. But ftbzip2 |
| module has no builtin bzip2 library and always requires |
| system bzip2 library. Thus SYSTEM_BZ2LIB is always yes, |
| it is not used. |

| |
| 2010-12-25 Harsha <mm.harsha@gmail.com> |
| |
| Apply Savannah patch #7422. |
| |
| If we encounter a space in a string then the sbit buffer is NULL, |
| height and width are 0s. So the check in ftc_snode_compare will |
| always pass for spaces (comparison with 255). Here the comments |
| above the condition are proper but the implementation is not. When |
| we create an snode I think it is the proper way to initialize the |
| width to 255 and then put a check for being equal to 255 in snode |
| compare function. |
| |
| * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with |
| value 255. |
| (ftc_snode_compare): Fix condition. |
| |
| 2010-12-13 Werner Lemberg <wl@gnu.org> |

| |
| 2010-12-09 Werner Lemberg <wl@gnu.org> |
| |
| [cff] Allow `hlineto' and `vlineto' without arguments. |
| |
| We simply ignore such instructions. This is invalid, but it doesn't |
| harm; and indeed, there exist such subsetted fonts in PDFs. |
| |
| Reported by Albert Astals Cid <aacid@kde.org>. |
| |
| * src/cff/cffgload.c (cff_decoder_parse_charstrings) |
| [cff_op_hlineto]: Ignore instruction if there aren't any arguments |

| |
| Since 2010-07-04, `find_variant_selector_charmap' returns |

| |
| 2010-11-01 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [ftsmooth] Improve rendering. |
| |
| * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3, |
| cubic deviations have been estimated _after_ UPSCALE, whereas |
| conic ones have been evaluated _before_ UPSCALE, which produces |
| inferior rendering results. Fix this. |
| Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has |

| |
| [cache] Change the hash types to FT_PtrDist. |
| |
| On LLP64 platforms (e.g. Win64), FT_ULong (32-bit) |
| variables are inappropriate to calculate hash values |
| from the memory address (64-bit). The hash variables |
| are extended from FT_ULong to FT_PtrDist and new |
| hashing macro functions are introduced. The hash |
| values on 16-bit memory platforms are changed, but |
| ILP32 and LP64 are not changed. The hash value in |
| the cache subsystem is not reverted to the memory |
| address, so using signed type FT_PtrDist is safe. |
| |
| * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash |
| function to replace `FTC_FACE_ID_HASH' for portability. |
| * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace |
| `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'. |
| * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto. |
| |
| * src/cache/ftccache.h (FTC_NodeRec): The type of the |
| member `hash' is changed from FT_UInt32 to FT_PtrDist. |
| |
| * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the |
| argument `hash' is changed from FT_UInt32 to FT_PtrDist. |

| * src/cache/ftccache.c (ftc_cache_add): Ditto. |
| (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto. |
| * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto. |
| * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto. |
| |
| * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type |
| of the internal variable `hash' is changed to FT_PtrDist |
| from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto. |
| (FTC_SBitCache_Lookup): Ditto. |
| (FTC_SBitCache_LookupScaler): Ditto. |
| * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto. |
| * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto. |
| Also the type of the internal variable `_idx' is changed to |
| FT_PtrDist from FT_UFast for better pointer calculation. |

| [cache] Hide internal macros incompatible with LLP64. |
| |
| `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and |
| `FTC_IMAGE_TYPE_HASH' are enclosed by |
| FT_CONFIG_OPTION_OLD_INTERNALS and hidden from |
| normal clients. |

| |
| Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist. |
| |
| On LLP64 platforms (e.g. Win64), unsigned long (32-bit) |
| cannot cover the memory address (64-bit). `FT_MEM_VAL' is |
| used for hashing only and not dereferred, so using signed |
| type FT_PtrDist is safe. |
| |
| * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the |
| return value from FT_ULong to FT_PtrDist. |
| (ft_mem_table_resize): The type of hash is changed to |
| FT_PtrDist. (ft_mem_table_get_nodep): Ditto. |
| |
| 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |

| Replace "%lx" for memory address by "%p", LLP64 platforms. |
| |
| On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover |
| the memory address (64-bit). Also the casts from the pointer |
| type to long int should be removed to preserve the address |
| correctly. |
| |
| * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". |
| (End_Profile) Ditto. |
| * src/truetype/ttinterp.c (Init_Context): Ditto. |

| [raccess] Skip unrequired resource access rules by Darwin VFS. |
| |
| When a resource fork access rule by Darwin VFS could open the |
| resource fork but no font is found in it, the rest of rules |
| by Darwin VFS are skipped. It reduces the warnings of the |
| deprecated resource fork access method by recent Darwin kernel. |
| Fix MacPorts ticket #18859: |
| https://trac.macports.org/ticket/18859 |
| |
| * src/base/ftobjs.c (load_face_in_embedded_rfork): |
| When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it |
| means that the file is possible to be `fopen'-ed but zero-sized. |
| Also there is a case that the resource fork is not zero-sized, |
| but no supported font exists in it. If a rule by Darwin VFS |
| falls into such cases, there is no need to try other Darwin VFS |
| rules anymore. Such cases are marked by vfs_rfork_has_no_font. |
| If it is TRUE, the Darwin VFS rules are skipped. |
| |
| 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [raccess] Grouping resource access rules based on Darwin VFS. |
| |
| MacOS X/Darwin kernel supports a few tricky methods to access |
| a resource fork via ANSI C or POSIX interface. Current resource |
| fork accessor tries all possible methods to support all kernels. |
| But if a method could open a resource fork but no font is found, |
| there is no need to try other methods older than tested method. |
| To determine whether the rule index is for Darwin VFS, a local |
| function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced. |
| To use this function in ftobjs.c etc but it should be inlined, |
| it is exposed by ftbase.h. |
| |
| * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify |
| the rules to access the resource fork. |
| (raccess_guess_rec): New structure to bind the rule function and |
| rule enum type. |
| (FT_Raccess_Guess): The list of the rule functions is replaced by |
| (raccess_guess_table): This. This is exposed to be used by other |
| intra module functions. |
| (raccess_rule_by_darwin_vfs): A function to return a boolean |
| if the rule specified by the rule index is based on Darwin VFS. |

| Prevent to open a FT_Stream for zero-sized file on non-Unix. |
| |
| builds/unix/ftsystem.c prevents to open an useless stream from |
| zero-sized file and returns FT_Err_Cannot_Open_Stream, but the |
| stream drivers for ANSI C, Amiga and VMS return useless streams. |
| For cross-platform consistency, all stream drivers should act |
| same. |
| |
| * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened |
| file is zero, FT_Err_Cannot_Open_Stream is returned. |
| * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto. |
| * src/vms/ftsystem.c (FT_Stream_Open): Ditto. |

| [cff] Truncate the element length at the end of the stream. |
| See Savannah bug #30975. |
| |
| * src/cff/cffload.c (cff_index_access_element): `off2', the offset |
| to the next element is truncated at the end of the stream to prevent |
| invalid I/O. As `off1', the offset to the requested element has |
| been checked by `FT_STREAM_SEEK', `off2' should be checked |
| similarly. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cff] Ignore CID > 0xFFFFU. |
| See Savannah bug #30975. |
| |
| * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if |

| 0xFFFFU. |
| |
| 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |

| See Savannah bug #30975. |
| |
| * src/cff/cffload.c (cff_charset_compute_cids): Don't increment |
| max_cid after detecting max CID. The array CFF_Charset->cids is |
| allocated by max_cid + 1. |
| (cff_charset_cid_to_gindex): Permit CID is less than or equal to |

| |
| [truetype] Sanitize the broken offsets in `loca'. |
| See Savannah bug #31040. |
| |
| * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the |
| offset to the requested entry in `glyf' exceeds the end of the |
| table, return offset=0, length=0. If `pos2', the offset to the next |
| entry in `glyf' exceeds the end of the table, truncate the entry |

| |
| [sfnt] Prevent overrunning in `post' table parser. |
| See Savannah bug #31040. |
| |
| * src/sfnt/ttpost.c (load_post_names): Get the length of `post' |
| table and pass the limit of `post' table to `load_format_20' and |
| `load_format_25'. |
| (load_format_20): Stop the parsing when we reached at the limit of |
| `post' table. If more glyph names are required, they are filled by |
| NULL names. |
| |
| 2010-09-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [truetype] Don't duplicate size->twilight structure to be freed. |
| See Savannah bug #31040 for detail. |
| |
| * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate |
| FT_GlyphZoneRec size->twilight to be freed. If duplicated, |
| `FT_FREE' erases the duplicated pointers only and leave original |
| pointers. They can cause the double-free crash when the burst |
| errors occur in TrueType interpreter and `free_buffer_in_size' is |
| invoked repeatedly. |
| |
| 2010-09-15 Werner Lemberg <wl@gnu.org> |
| |
| Make bytecode debugging with FontForge work again. |

| |
| 2010-09-14 Werner Lemberg <wl@gnu.org> |
| |
| Improve tracing messages. |

| |
| 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Ignore the environmental setting of LIBTOOL. |
| Patch is suggested by Adrian Bunk, to prevent unexpected |
| reflection of environmental LIBTOOL. See: |
| https://savannah.nongnu.org/patch/?7290 |
| |
| * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to |
| $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR) |
| by default. |
| * configure: When configured for the building out of source tee, |
| FT_LIBTOOL_DIR is set to $(OBJ_DIR). |

| |
| [truetype] Decrease the trace level catching the interpreter error. |
| |
| * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level |

| from` FT_TRACE7' to `FT_TRACE1'. |
| |
| 2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [truetype] Prevent bytecode reuse after the interpretation error. |
| |
| * src/truetype/ttinterp.c (free_buffer_in_size): New function to |
| free the buffer allocated during the interpretation of this glyph. |
| (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if |
| an error occurs in the bytecode interpretation. The interpretation |
| of invalid bytecode may break the function definitions and referring |
| them in later interpretation is danger. By unsetting these flags, |
| `fpgm' and `prep' tables are executed again in next interpretation. |

| |
| Additional fix for Savannah bug #30306. |
| |
| * src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the |
| POST fragment is 0, the segment is completely ignored. The declared |
| length of the segment is not cared at all. According to Adobe |
| Technical Note 5040, type 0 segment is a comment only and should not |

| [pshinter] Fix Savannah bug #30106. |
| |
| Point numbers for FreeType's implementation of hinting masks are |
| collected before the final number of points of a glyph has been |
| determined; in particular, the code for handling the `endchar' |
| opcode can reduce the number of points. |
| |
| * src/pshinter/pshalgo.c (psh_glyph_find_strong_points): Assure that |
| `end_point' is not larger than `glyph->num_points'. |
| |
| 2010-06-11 Werner Lemberg <wl@gnu.org> |
| |
| [cff]: Improve debugging output. |
| |
| * src/cff/cffgload.c (cff_decoder_parse_charstrings) |
| <cff_op_hintmask>: Implement it. |

| [psaux] Fix Savannah bug #29846. |
| |
| Previously we discovered fonts which used `setcurrentpoint' to set |
| the initial point of a contour to 0,0. This caused FreeType to |
| raise an error, because the `setcurrentpoint' operator is only |
| supposed to be used with the results from an OtherSubr subroutine. |
| |
| This was fixed by simply ignoring the error and carrying on. |
| |
| Now we have found a font which uses setcurrentpoint to actually |
| establish a non-zero point for a contour during the course of a |
| glyph program. FWIW, these files may be produced by an application |
| called `Intaglio' on the Mac, when converting TrueType fonts to |
| Type 1. |
| |
| The fix allows the new invalid behaviour, the old invalid behaviour |
| and real proper usage of the operator to work the same way as Adobe |
| interpreters apparently do. |
| |
| * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make |
| `setcurrentpoint' use the top two elements of the stack to establish |
| unconditionally the current x and y coordinates. |
| |
| Make the `flex' subroutine handling (OtherSubr 0) put the current |
| x,y coordinates onto the stack, instead of two dummy uninitialised |
| values. |
