89f50647 | 2013-03-14 17:50:49 | */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code. | |
|
059bc335 | 2013-03-14 10:27:35 | */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op. | |
|
c58ce3be | 2013-03-13 11:06:39 | Introduce `FT_THROW' macro. The idea is to replace code like return FT_Err_Foo_Bar; or return CFF_Err_Foo_Bar; with return FT_THROW( Foo_Bar ); The FT_THROW macro has two functions: . It hides the module specific prefix. . In debug mode, it calls the empty function `FT_Throw' which can be thus used to set a breakpoint. * include/freetype/internal/ftdebug.h (FT_THROW): New macro. (FT_Throw): New prototype. * src/base/ftdebug.c (FT_Throw): New function. | |

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

|
b4ac30b0 | 2013-01-02 22:21:37 | [base] Reduce trigonometric algorithms. After we get within 45 degrees by means of true 90-degree rotations, we can remove initial 45-degree CORDIC iteration and start from atan(1/2) pseudorotation, reducing expansion factor thereby. * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macros. (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Update. * src/tools/cordic.py: Bring up to date with trigonometric core. * docs/CHANGES: Old typo. | |
|
3ffb822e | 2012-12-21 16:45:27 | Check parameters of `FT_Outline_New'. Problem reported by Robin Watts <robin.watts@artifex.com>. * src/base/ftoutln.c (FT_Outline_New_Internal): Ensure that `numContours' and `numPoints' fit into FT_Outline's `n_points' and `n_contours', respectively. | |
|
d7383b7b | 2012-12-20 01:03:22 | [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 values. (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial rotation. | |
|

|
8ac5c5c8 | 2012-12-15 23:33:55 | [base] Fix 11-year old bug. Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has always been slightly less than the correct value, which has been given in the comment as a hexadecimal. As a result, vector lengths were underestimated and rotated vectors were shortened. | |
|
72e976d4 | 2012-11-27 21:18:34 | [ftstroke] Minor improvement. * src/base/ftstroke.c: Replace nested FT_DivFix and FT_MulFix with FT_MulDiv. | |

|
dd5718c7 | 2012-11-04 00:57:57 | [base] Fortify emboldening code against egregious distortions. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Threshold emboldening strength when it leads to segment collapse. | |
|
48ce226a | 2012-11-03 22:27:27 | [base] Clean up emboldening code and improve comments there. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Replace sequential calls to FT_MulFix and FT_DivFix with FT_MulDiv. Mention that bisectors are used to figure out the shift direction. | |
|
073a4cef | 2012-09-15 09:10:06 | Use `FT_Module' instead of `FT_Library' argument in property funcs. This internal change simplifies access to global module data. * include/freetype/internal/services/svprop.h (FT_Properties_SetFunc, FT_Properties_GetFunc): Change accordingly. * src/base/ftobjs.c (ft_property_do), src/autofit/afmodule.c (af_property_set, af_property_get): Updated. | |
|
0f8fd88e | 2012-08-30 23:31:55 | Implement properties to control FreeType modules. * include/freetype/fterrdef.h (FT_Err_Missing_Property): New error code. * include/freetype/ftmodapi.h (FT_Property_Set, FT_Property_Get): New API. * include/freetype/internal/services/svprop.h: New file. * include/freetype/internal/ftserv.h (FT_SERVICE_PROPERTIES_H): New macro. * src/base/ftobjs.c: Include FT_SERVICE_PROPERTIES_H.

|
ba67957d | 2012-03-03 12:27:18 | Fix Savannah bug #35660. For some divisions, we use casts to 32bit entities.

c7c4d68b | 2012-01-17 15:13:50 | [raccess] Modify for PIC build. Based on the patch provided by Erik Dahlstrom <ed@opera.com>, http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html 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. * include/freetype/internal/ftrfork.h: FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined to replace raccess_guess_table[] in both of PIC and non-PIC modes. * 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' storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve the function pointer from `ft_raccess_guess_table' storage in `BasePIC' structure. * src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with FT_RACCESS_GUESS_TABLE_GET. (raccess_get_rule_type_from_rule_index): Add `library' as the first argument to the function, to retrieve the storage of `ft_raccess_guess_table' from it. Also `raccess_guess_table' is replaced by FT_RACCESS_GUESS_TABLE_GET. (ft_raccess_rule_by_darwin_vfs): Ditto. | |

3c966818 | 2012-01-15 23:35:31 | 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}. | |

09f3e41c | 2012-01-15 02:48:47 | [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. | |
|
0614febc | 2012-01-15 01:29:41 | [base] Insert explict 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. | |
|
2fb22d56 | 2011-12-08 11:55:06 | Fix serious scaling bug in `FT_Get_Advances'. * src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by `FT_Load_Glyph' must be simply multiplied by 1024. | |

714ee56a | 2011-12-02 21:14:18 | [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. * 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. * builds/mac/FreeType.m68k_far.make.txt: Ditto. * builds/mac/FreeType.ppc_classic.make.txt: Ditto. * builds/mac/FreeType.ppc_carbon.make.txt: Ditto. | |

8b90cf0b | 2011-11-13 16:30:59 | Add FT_Get_PS_Font_Value() API. This allows a Type 1 font face to be interrogated to retrieve most of the dictionary keys (keys not relevant to FreeType's Type 1 interpreter are not available). * include/freetype/internal/services/svpsinfo.h (PS_GetFontValueFunc): New typedef. (PSInfo): Add `ps_get_font_value'. (FT_DEFINE_SERVICE_PSINFOREC): Updated. * include/freetype/internal/t1types.h (T1_EncodingType): Moved to... * include/freetype/t1tables.h: Here.

aecbfe1b | 2011-07-02 12:09:52 | [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. * src/base/ftstroke.c: Revised. * include/freetype/ftstroke.h: Updated. | |

21b1a0de | 2011-04-12 09:26:43 | 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... (FT_Stream_GetU*): Functions which read unsigned integers. Update all macros accordingly. * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated. | |

463dddad | 2010-10-13 17:20:27 | [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. | |

c081a4a9 | 2010-10-13 17:05:42 | [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. | |
