75df7060	2011-02-01T07:36:27	[cff] Ignore unknown operators in charstrings. Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Emit tracing message for unknown operators and continue instead of exiting with a syntax error.
396b11b8	2010-12-09T23:16:18	[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.
223cb1b5	2010-08-06T06:55:09	[cff] Add comment to clarify current implementation of `pop' operator.
d9b3e394	2010-08-05T17:10:32	[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.
11d65e8a	2010-08-04T14:43:29	[cff] Improve stack overflow test. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Check stack after execution of operations too.
2de6b8a3	2010-07-17T13:39:50	[cff] Final try to fix `hintmask' and `cntrmask' limit check. 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	2010-07-05T06:40:02	[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.
ae425e51	2010-06-29T12:31:08	Fix minor tracing issues. * src/cff/cffgload.c, src/truetype/ttgload.c: Adjust tracing levels.
18b552f6	2010-06-27T15:41:02	[cff] Really fix `hintmask' and `cntrmask' limit check. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: Fix thinko and handle tracing also.
4f7851e3	2010-06-27T13:03:54	[cff] Fix memory leak. * src/cff/cffgload.c (cff_operator_seac): Free charstrings even in case of errors.
e9f0cdb6	2010-06-27T12:34:19	[cff] Protect against invalid `hintmask' and `cntrmask' operators. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: Ensure that we don't exceed `limit' while parsing the bit masks of the `hintmask' and `cntrmask' operators.
3624110c	2010-06-11T23:00:22	[cff]: Improve debugging output. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: Implement it.
7d3d2cc4	2010-06-09T09:14:09	Fix Savannah bug #30082. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_callothersubr>: Protect against stack underflow.
236fc8e1	2010-05-18T11:00:39	Apply patch #7196. * src/cff/cffgload.c (cff_slot_load): Prevent crash if CFF subfont index is out of range.
03b3da8b	2010-03-02T13:00:55	Improve CFF string (especially glyphname) lookup performance. We do this by avoiding memory allocation and file I/O. 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. (cff_index_get_pointers): Add `pool' parameter which allows to insert an extra NUL character for each String INDEX entry. (cff_index_get_name): Make it a local function. (cff_index_get_string): New function. (cff_subfont_load): Updated. (cff_font_load): Initialize `num_strings', `strings', and `string_pool' fields in the `CFF_FontRec' structure. (cff_index_get_sid_string): Use `cff_index_get_string' instead of `cff_index_get_name'. (cff_font_done): Updated. * src/cff/cffload.h: Don't include PS cmaps service. (cff_index_get_string): Added. (cff_index_get_sid_string): Updated. * src/cff/cffobjs.c: Don't include PS cmaps service and FT_INTERNAL_POSTSCRIPT_HINTS_H. (cff_size_get_globals_funcs, cff_slot_init): Updated. (cff_face_init): Follow `cff_index_get_name', `cff_index_get_string', and `cff_index_get_sid_string' changes. * src/cff/cffcmap.c (cff_sid_free_glyph_name): Removed. (cff_sid_to_glyph_name): Use `cff_index_get_cid_string'. (cff_cmap_unicode_init): Updated. * src/cff/cffdrivr.c: Don't include PS cmap service. (cff_get_glyph_name): Avoid unnecessary lookup for POSTSCRIPT_CMAPS service. (cff_get_glyph_name, cff_ps_get_font_info, cff_get_ros): Follow API `cff_index_get_sid_string' change. (cff_get_name_index): Use `cff_index_get_string' instead of `cff_index_get_name'. * src/cff/cffgload.c: Don't include FT_INTERNAL_POSTSCRIPT_HINTS_H. (cff_decoder_init, cff_decoder_prepare): Updated.
63e7aac3	2010-02-10T07:13:27	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	2010-02-10T07:02:43	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.
f19e46f3	2010-01-27T10:04:50	Fix Savannah bug #28678. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_load_glyph): Handle vertical metrics correctly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle vertical metrics correctly. (T1_Load_Glyph): Don't synthesize vertical metrics.
8821cc5d	2009-11-04T07:21:15	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	2009-10-19T21:09:13	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	2009-10-18T10:47:11	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	2009-09-10T16:09:55	[Win64] Improve the computation of random seed from stack address.
4694ea2b	2009-09-02T13:06:33	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.
d77cd8ce	2009-08-27T00:10:56	Fix rendering of horizontally compressed CFFs. Bug reported by Ivan Nincic <inincic@pdftron.com>. * src/cff/cffgload.c (cff_slot_load): Thinko: Check `xx' element of `font_matrix' also. * docs/CHANGES: Updated.

a813cf48	2009-08-01T00:30:15	cff: Fix some data types mismatching with their sources.
24370d67	2009-06-28T02:11:51	Uff, another thinko.
e7389a44	2009-06-28T01:25:55	[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	2009-06-26T06:15:41	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.
1f540eff	2009-06-20T13:24:08	Remove unused variables. * include/freetype/internal/psaux.h (T1_BuilderRec), src/cff/cffgload.h (CFF_Builder): Remove `last'. Update all users.
541ab5ad	2009-06-20T07:31:44	[cff] Revert last change. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Do it. Next time, don't confuse Type 2 charstring opcodes with TOP DICT values...
f1631f2d	2009-06-19T23:50:37	[cff] Fix handling of reserved byte 0xFF. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Abort if byte 0xFF is encountered.

b211651a	2008-09-12T16:27:48	* autogen.sh, builds/unix/configure.raw, include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor beautifying. * include/freetype/ftadvanc.h, include/freetype/ftgasp.h, include/freetype/ftlcdfil.h: Protect against FreeType 1. Some other minor fixes. * devel/ftoption.h: Synchronize with include/freetype/config/ftoption.h. Formatting, documentation improvements.
28534d61	2008-09-01T21:35:21	* 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	2008-08-06T09:09:41	Add one more example to the documentation of FT_Glyph_To_Bitmap.
806f5934	2008-07-30T05:28:37	* 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	2008-07-26T21:22:20	* src/cff/cffgload.c (cff_decoder_prepare, cff_decoder_parse_charstrings): Improve debug output.
e6e6eade	2008-05-14T23:05:38	Finish fix of scaling bug of CID-keyed CFF subfonts. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New functions. * src/cff/cffobjs.h (CFF_Internal): New struct. 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	2007-12-06T17:17:30	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.
5b4d435a	2007-06-20T07:07:55	* src/cff/cffgload.c (cff_slot_load): Fix logic of 2007-05-28 change.

a42567bf	2007-01-25T12:23:37	- same CFF loader fix (stricter checking though than Werner's version) - document light auto-hinter improvements
f6294399	2007-01-06T07:47:45	formatting, copyright years
5dbdb6c3	2007-01-05T13:14:08	* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffgload.c, src/cff/cfftypes.h: formatting + do not load the CFF index offsets into memory, since this wastes a lot of heap memory with large Asian CFF fonts. There is no significant performance loss
913a3650	2006-11-19T09:19:17	Because FT_Load_Glyph expects CID values for CID-keyed fonts, the test for a valid glyph index must be deferred to the font drivers. This patch fixes Savannah bug #18301. * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'. * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c (FNT_Load_Glyph): Check validity of `glyph_index'.
26377008	2006-03-21T18:41:40	* src/cff/cfftypes.h (CFF_CharsetRec): Add `max_cid' member. * src/cff/cffload.c (cff_charset_load): Set `charset->max_cid'. * src/cff/cffgload.c (cff_slot_load): Change type of third parameter to `FT_UInt'. Check range of `glyph_index'. * src/cff/cffgload.h: Updated.
f5aa47be	2006-02-14T06:40:10	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.

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 !!

(parse_charstrings): Parse /CharStrings in second run without assigning values. (parse_dict): Skip all /CharStrings arrays but the first. 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.
84c60bba	2004-01-01T08:21:30	* src/cff/cffgload.c (cff_decoder_parse_charstrings) [FT_DEBUG_LEVEL_TRACE]: Use `%ld' in FT_TRACE4. <cff_op_flex1>: Change type of dx and dy to FT_Pos and remove cast for accessing arguments.

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.
2acb963b	2003-04-23T06:47:12	Cleanups.
46960df7	2003-02-13T17:49:27	The incremental interface now passes the old metrics when asking for replacement metrics so that they can be modified, not just replaced. For example, CFF fonts need this.

b08fe2dc	2002-08-27T20:20:29	* massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.
9eefed12	2002-08-23T10:08:38	Simplified the incremental loading system for CFF fonts and fixed a problem with the handling of the deprecated version of the Type 2 endchar command, that emulates Type 1 'seac'. This version now works with the GhostScript-to-FreeType bridge currently under development.

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.

[Win64] Improve the computation of random seed from stack address.

4694ea2b

2009-09-02T13:06:33

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.

* 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.

* 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 !!

updating sources to support the new FT_LOAD_TARGET_ constants to support target-specific hinting

b08fe2dc

2002-08-27T20:20:29

* massive re-formatting changes to many, many source files. I don't want to list them all here. The operations performed were all logical transformations of the sources: - trying to convert all enums and constants to CAPITALIZED_STYLE, with #define definitions like #define my_old_constants MY_NEW_CONSTANT - big, big update of the documentation comments * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c, include/freetype/ftimage.h: adding support for LCD-optimized rendering though the new constants/enums: FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V FT_PIXEL_MODE_LCD, FT_PIXEL_MODE_LCD_V this is still work in progress, don't expect everything to work correctly though most of the features have been implemented. * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering targets: FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering FT_LOAD_TARGET_MONO :: monochrome bitmaps FT_LOAD_TARGET_LCD :: horizontal RGB/BGR decimated hinting & rendering FT_LOAD_TARGET_LCD_V :: vertical RGB/BGR decimated hinting & rendering note that FT_LOAD_TARGET_NORMAL is 0, which means that the default behaviour of the font engine is _unchanged_.
