[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'. | |

unused. | |

2013-04-13 Werner Lemberg <wl@gnu.org> | |
[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. | |
(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_driver_init): Set default property values. | |
* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files. | |
* src/cff/cf2*.*: New files, containing the Adobe engine. | |

http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5 | |
* include/freetype/internal/fttrace.h: Add `bitmap'. | |
* src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c' | |
(FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing, | |
convert resulting bitmap to a uniform format and compute a checksum. | |
Use `bitmap' category for the tracing message. | |

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 backwards 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. | |

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 | |

[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 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. | |

[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. | |
2013-01-12 Alexei Podtelezhnikov <apodtele@gmail.com> | |
[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. | |

[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. | |

[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. | |

assignment of F_dot_P to its theoretical maximum in case we decide | |
to scale back its type later. | |

[autofit] Implement Infinality's `increase glyph heights'. | |
This is an improved version of a similar fix contained in the | |
so-called `Infinality patch', taken from | |
http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2 | |
which addresses various enhancements of the auto-hinter. Without | |
properties to control a module's metadata it wasn't possible to | |
adapt the patches because everything was originally controlled by | |
environment variables which I consider not suitable in general. | |
A patch to control `increase_x_height' follows. | |
* src/autofit/afglobal.h (AF_PROP_INCREASE_X_HEIGHT_MIN, | |
AF_PROP_INCREASE_X_HEIGHT_MAX): New macros. | |

`-static' works | |
On 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. | |

[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 | |

commit. | |

variable to store control value cutin. Simplify the conditional for | |
ignore_x_mode. Adjust rounding calls to pass only two values. | |

[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 | |
http://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. | |

[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. | |

Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()' | |
are renamed with `ft_' suffixes. | |
* src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed | |
to `ft_raccess_rule_by_darwin_vfs()'. | |
* src/base/ftobjs.c: Ditto. | |
* src/base/ftrfork.c: Declarations of FT_RFork_Rule, | |
raccess_guess_rec, are moved to... | |
* include/freetype/internal/ftrfork.h: Here. | |

FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined | |
to replace raccess_guess_table[] in both of PIC and non-PIC | |

* src/base/ftrfork.c: raccess_guess_table[] array is rewritten | |
by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}. | |
* src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table' | |

the function pointer from `ft_raccess_guess_table' storage in | |
`BasePIC' structure. | |

[autofit] Fix the inclusion of `aflatin2.h' in PIC file. | |
* src/autofit/afpic.c: Include `aflatin2.h' when | |
FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so. | |
Unconditionally inclusion causes declared but unimplemented | |
warning by GCC 4.6. | |
2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
[cff] Remove redundant declarations of cff_cmap_XXX_class_rec. | |
* src/cff/cffpic.c: The declarations of | |
FT_Init_Class_cff_cmap_encoding_class_rec() and | |
FT_Init_Class_cff_cmap_unicode_class_rec() are removed. | |
They can be obtained by the inclusion of cffcmap.h. | |
cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares | |
FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode. | |
2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
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, | |
init}. | |
* src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}. | |
* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free, | |
init}. | |
* src/psnames/pspic.h: Declare psnames_module_class_pic_{free, | |
init}. | |
* src/raster/rastpic.h: Declare | |
ft_raster{1,5}_renderer_class_pic_{free,init} | |
* src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}. | |
* src/smooth/ftspic.h: Declare | |
ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}. | |
* src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}. | |
2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
Make pspic.c to include module error header to fix multi build. | |
* src/psnames/pspic.c: Include `psnamerr.h'. | |
2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
[base] Fix a dereference of uninitialized variable in PIC mode. | |
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be | |
set before derefering to obtain `library'. The initialization | |
of `clazz', `glyph', `library' and NULL pointer check are | |
reordered to minimize PIC conditonals. | |
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. | |
2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6. | |
Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET | |
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. | |
* src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library' | |
under PIC configuration, and set it if non-NULL module is given. | |
* src/psnames/psmodule.c (psnames_get_interface): Ditto. | |
2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |

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/ftbase.h: Remove DARWIN_NO_CARBON. | |
* src/base/ftbase.c: Ditto. | |
* src/base/ftobjs.c: Ditto. | |

[apinames] Fix the overflow of signed integer hash. | |
* src/tools/apinames.c (names_add): Change the type of `h' from | |

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. | |

[smooth] Slightly optimize conic and cubic flatterners. | |
* src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move | |
out some code from the main loop to speed it up. | |
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. | |
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First | |
code in valid LZW stream must be 0..255. | |
<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent, | |
code > free_ent is invalid. | |

[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 | |
http://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. | |

[gxvalid] Cleanup. | |
Some invalid, overrunning, unrecommended non-zero values | |
are cared in paranoid validation mode only. There are | |
many lines looking like: | |
if ( valid->root->level >= FT_VALIDATE_PARANOID ) | |
FT_INVALID_xxx; | |
To simplify them, GXV_SET_ERR_IF_PARANOID( err ) is | |
introduced for more paranoid validation in future. | |
* src/gxvalid/gxvcommn.h (IS_PARANOID_VALIDATION): | |
New macro to assure valid->root->level is more or | |
equal to FT_VALIDATE_PARANOID. (GXV_SET_ERR_IF_PARANOID): | |

[autofit] Add bluezones for CJK Ideographs. | |
To remove extremas of vertical strokes of CJK Ideographs at | |

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 | |

[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 | |

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. | |
2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
[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'. | |

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 (comparision 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. | |

[cff] Allow `hlineto' and `vlineto' without arguments. | |
We simply ignore such instructions. This is invalid, but it doesn't | |

[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. | |

2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
[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. | |
(FTC_Cache_NewNode): 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. | |
2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
[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. | |
For the history of these macros, see the investigation: | |

2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
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: | |
http://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. | |
2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
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 | |
greater than 0xFFFFU. CFF font spec does not mention maximum CID in | |
the font, but PostScript and PDF spec define that maximum CID is | |
0xFFFFU. | |
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
[cff] Make trace message in` cff_charset_load' verbose. | |

allocated by max_cid + 1. | |
(cff_charset_cid_to_gindex): Permit CID is less than or equal to | |
CFF_Charset->max_cid. | |
* src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is | |
calculated as CFF_Charset->max_cid + 1. | |

[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 | |
length at the end of `glyf' table. | |

[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. | |

2010-08-31 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: | |
http://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). | |

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. | |
This fixes Savannah bug #30798, reported by Robert Święcki. | |

* src/cff/cffgload.c (cff_decoder_parse_charstrings) | |
<cff_op_hintmask>: It is possible that there is just a single byte | |
after the `hintmask' or `cntrmask', e.g., a `return' instruction. | |
2010-07-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |

minimum character code passed by a legacy rogue client by... | |
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE): | |
This. It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is | |
undefined (thus the rogue client compatibility is not required). | |

encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search | |
earlier one. | |
(FT_Set_Charmap): When a charmap matching with requested | |
charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search | |
earlier one. | |
(FT_Get_Charmap_Index): When a requested charmap is found | |
after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap | |
index. | |
2010-07-04 Werner Lemberg <wl@gnu.org> | |
TrueType hinting is no longer patented. | |
* include/freetype/config/ftoption.h, devel/ftoption.h | |
(TT_CONFIG_OPTION_BYTECODE_INTERPRETER): Define. | |
(TT_CONFIG_OPTION_UNPATENTED_HINTING): Undefine. | |

2010-07-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
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 | |
be loaded for the interpreter. Reported by Robert Święcki. | |
2010-07-01 Werner Lemberg <wl@gnu.org> | |
[truetype] Protect against code range underflow. | |
* src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF): Don't allow | |

[smooth] Fix Savannah bug #30263. | |
* src/smooth/ftgrays.c (gray_render_span): Use cast to `unsigned | |
int' to avoid integer overflow. | |
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller | |
threshold values for `width' and `height'. This is not directly | |
related to the bug fix but makes sense anyway. | |
2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |
Initial fix for Savannah bug #30306. | |
* src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the | |
length of fragment declared in the POST fragment header, and prevent | |
an underflow in length calculation. Some fonts set the length to | |
zero in spite of the existence of a following 16bit `type'. | |
Reported by Robert Święcki. | |
2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> | |

[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'. | |

[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. | |
