|
396b11b8 | 2010-12-09 23:16:18 | [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 on the stack. | |
|

|
d9b3e394 | 2010-08-05 17:10:32 | [cff] Don't use any values in decoder after parsing error. * src/cff/cffgload.c (cff_slot_load): Skip the evaluations of the values in decoder, if cff_decoder_parse_charstrings() returns any error. | |

Problem reported by Tobias Wolf <towolf@gmail.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: Sigh. I'm apparently too silly to fix this correctly in less than three tries. | |
|
2dc76a46 | 2010-07-05 06:40:02 | [cff] Next try to fix `hintmask' and `cntrmask' limit check. Problem reported by malc <av1474@comtv.ru>. * 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. | |
|

This is Savannah patch #7104. * src/cff/cfftypes.h: Include PS cmaps service and FT_INTERNAL_POSTSCRIPT_HINTS_H. (CFF_SubFontRec): Remove `num_local_subrs'. (CFF_FontRec): Add `num_strings', `strings', and `string_pool' fields. Remove `string_index' and `num_global_subrs' fields. Use real types instead of `void' for `pshinter' and `psnames' fields. * src/cff/cffload.c: Don't include PS cmaps service.

63e7aac3 | 2010-02-10 07:13:27 | Really fix Savannah bug #28678 (part 2). Since we consider `sbw' for the horizontal direction only, we still have to synthesize vertical metrics if the user wants to use the vertical writing direction. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is set. | |
|
980b76ea | 2010-02-10 07:02:43 | Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of *one* direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it. | |
|

(T1_Load_Glyph): Don't synthesize vertical metrics. | |
 |
8821cc5d | 2009-11-04 07:21:15 | Add basic support for Type1 charstrings in CFF. * src/cff/cffgload.c (CFF_Operator, cff_argument_counts): Handle `seac', `sbw', and `setcurrentpoint' opcodes. (cff_compute_bias): Add parameter to indicate the charstring type. Update all callers. (cff_operator_seac): Add parameter for side bearing. (cff_decoder_parse_charstrings): Updated for more Type1 support. | |
|
2d15120c | 2009-10-19 21:09:13 | Fix handling of `get' and `put' CFF instructions. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_get, cff_op_put>: Appendix B of Adobe Technote #5177 limits the number of elements for the `get' and `put' operators to 32. * src/cff/cffgload.h (CFF_MAX_TRANS_ELEMENTS): Define. (CFF_Decoder): Use it for `buildchar' and remove `len_buildchar'. | |
|
d90567b1 | 2009-10-18 10:47:11 | Fix handling of `dup' CFF instruction. Problem and solution reported by Ning Dong <flintning@163.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_dup>: Increase `args' by 2, not 1. | |

0729bc9f | 2009-09-10 16:09:55 | [Win64] Improve the computation of random seed from stack address. | |
|
4694ea2b | 2009-09-02 13:06:33 | Improve vertical metrics calculation (Savannah bug #27364). The calculation of `vertBearingX' is not defined in the OTF font spec so FreeType does a `best effort' attempt. However, this value is defined in the PDF and PostScript specs, and that algorithm is better than the one FreeType currently uses: FreeType: Use the middle of the bounding box as the X coordinate of the vertical origin. Adobe PDF spec: Use the middle of the horizontal advance vector as the X coordinate of the vertical origin. FreeType's algorithm goes wrong if you have a really small glyph (like the full-width, circle-like dot at the end of the sentence, as used in CJK scripts) with large bearings. With the FreeType algorithm this dot gets centered on the baseline; with the PDF algorithm it gets the correct location (in the top right). Note that this is a serious issue, it's like printing the dot at the end of a Roman sentence at the center of the textline instead of on the baseline like it should. So i believe the PDF spec's algorithm should be used in FreeType as well. The `vertBearingY' value for such small glyphs is also very strange if no `vmtx' information is present, since the height of the bbox is not representable for the height of the glyph visually (the whitespace up to the baseline is part of the glyph). The fix also includes some code for a better estimate of `vertBearingY'. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Estimate for `vertBearingY' now works better for small glyphs completely above or below the baseline into account. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Vertical metrics information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS was not defined. * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. | |

e7389a44 | 2009-06-28 01:25:55 | [psaux, cff] Protect against nested `seac' calls. * include/freetype/internal/psaux.h (T1_Decoder), src/cff/cffgload.h (CFF_Decoder): Add `seac' boolean variable. * src/cff/cffgload.c (cff_operator_seac, cff_decoder_parse_charstrings), src/psaux/t1decode.c (t1operator_seac, t1_decoder_parse_charstrings): Use it. | |
|
858abbed | 2009-06-26 06:15:41 | For warning messages, replace FT_ERROR with FT_TRACE0. FT_ERROR is now used only if a function produces a non-zero `error' value. Formatting, improving and harmonizing debug strings. | |

 |
28534d61 | 2008-09-01 21:35:21 | * include/freetype/ftadvanc.h, src/base/ftadvanc.c, include/freetype/config/ftheader.h, include/freetype/freetype.h, src/base/Jamfile, src/base/rules.mk, src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffgload.h, src/truetype/ttdriver.c, src/truetype/ttgload.h, src/truetype/ttgload.c, src/type1/t1driver.c, src/type1/t1gload.h, src/type1/t1gload.c: Add a new header named FT_ADVANCES_H declaring some new APIs to extract the advances of one or more glyphs without necessarily loading their outlines. Also provide 'fast loaders' for the TrueType, Type1 and CFF font drivers (more to come later) * autogen.sh: add checks for minimum version of the 'autotools' stuff. | |
|
da32d705 | 2008-08-06 09:09:41 | Add one more example to the documentation of FT_Glyph_To_Bitmap. | |
|
806f5934 | 2008-07-30 05:28:37 | * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer assume that the first argument on the stack is the bottom-most element. Two reasons: o According to people from Adobe it is missing in the Type 2 specification that pushing of additional, superfluous arguments on the stack is prohibited. o Acroread in general handles fonts differently, namely by popping the number of arguments needed for a particular operand (as a PS interpreter would do). In case of buggy fonts this causes a different interpretation which of the elements on the stack are superfluous and which not. Since there are CFF subfonts (embedded in PDFs) which rely on Acroread's behaviour, FreeType now does the same. | |
|
bdcfddcd | 2008-07-26 21:22:20 | * src/cff/cffgload.c (cff_decoder_prepare, cff_decoder_parse_charstrings): Improve debug output. | |

It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.

bd7e1c3c | 2007-12-06 17:17:30 | Pass options from one configure script to another as-is (not expanded). This is needed for options like --includedir='${prefix}/include'. * builds/unix/detect.mk, configure: Prevent argument expansion in call to the (real) `configure' script. * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if TT_USE_BYTECODE_INTERPRETER isn't defined. There exist CFFs which contain opcodes for the Type 1 operators `hsbw' and `closepath' which are both invalid in Type 2 charstrings. However, it doesn't harm to support them. * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and `cff_op_closepath.' (cff_argument_counts): Ditto. (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath) and 13 (hsbw) which are invalid in Type 2 charstrings. | |

f5aa47be | 2006-02-14 06:40:10 | Clean up the SFNT_Interface. Table loading functions are now named after the tables' tags; `hdmx' is TrueType-specific and thus the code is moved to the truetype module; `get_metrics' is moved here from the truetype module so that the code can be shared with the cff module. This pass involves no real changes. That is, the code is moved verbatim mostly. The only exception is the return value of `tt_face_get_metrics'. * include/freetype/internal/sfnt.h, src/sfnt/rules.mk, src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c, src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface. * src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading and parsing code is moved here. Move `tt_face_get_metrics' here from the truetype module. The return value is changed from `void' to `FT_Error'. * include/freetype/internal/fttrace.h: New trace: ttmtx. * src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and parsing code is moved here. New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'. `tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist. * src/cff/cffgload.c, src/cff/cffobjs.c: Update. * src/truetype/ttgload.c, src/truetype/ttobjs.c: Update. | |

6a681fa8 | 2006-01-27 12:11:22 | * src/autofit/afwarp.c: simple #ifdef to prevent compilation when the warp hinter isn't active (it shouldn't, still experimental) * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid" and "otvalid" from the list of modules that are linked statically to a given FreeType library. Functionality has been moved to the "ftvalid" CVS module. note also that current Make-based build system still compiles the modules though... * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING, which controls the definitions of the memory management functions to avoid warnings with recent versions of GCC. this macro is only here to be disabled, in case we detect problems with the new scheme. NOTE: disable macro to use the memory debugger. this will be fixed later !! | |

We need this for non-standard fonts like `Optima' which have different outlines depending on the resolution. Note that there is no guarantee that we get fitting /Subrs and /CharStrings arrays; this can only be done by a real PS interpreter. | |

Updated. * src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask' is declared twice. It is perhaps better to modify the zlip source files directly instead of this hack. (zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts to make build with g++ successful. | |
