16586859	2020-06-13T21:15:45	Remove redundant inclusion of `ft2build.h'. * /: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
e1339133	2020-06-08T13:31:55	Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. /: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

78d85b9c	2018-06-04T18:42:29	Restore missing comment lines and other minor fixes
9ac9060d	2018-06-03T09:01:17	[GSoC] src/.: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

Minor code changes.
78df3c27	2017-10-12T18:13:08	Extract width parsing from Type 1 parser. Duplicate the fast advance width calculations from the old parser. This is to facilitate adding options for compiling out the old parser. * src/psaux/t1decode.{c,h} (t1_decoder_parse_metrics): New function. * include/freetype/internal/psaux.h (T1_Decoder_Funcs): New entry `parse_metrics'. * src/psaux/psauxmod.c: Set the new entry. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Separate conditional for selecting engine.

cb3f4c61	2017-09-25T06:44:51	Add missing objects for Type 1 (1/2). Move `CF2_Font' instance to `PS_Decoder'. This is the context for the interpreter and since it is currently stored in `CFF_Font', is unavailable in Type 1 mode. * include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New `cf2_instance' field. * src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to `PS_Decoder'. * src/psaux/t1decode.c (t1_decoder_done): Add finalization code. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Update accesses.
dcd8de27	2017-06-09T11:21:58	/: Remove `OVERFLOW_' prefix. This increases readability.

f958c48e	2017-03-24T09:15:10	[psaux] Better protect `flex' handling. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=935 * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <callothersubr>: Since there is not a single flex operator but a series of subroutine calls, malformed fonts can call arbitrary other operators after the start of a flex, possibly adding points. For this reason we have to check the available number of points before inserting a point.
563ae780	2017-01-04T20:16:34	Update copyright year.
248eaa4f	2017-01-03T00:27:07	Various fixes for clang's undefined behaviour sanitizer. * src/cff/cffload.c (FT_fdot14ToFixed): Fix casting. (cff_blend_doBlend): Don't left-shift negative numbers. Handle 5-byte numbers byte by byte to avoid alignment issues. * src/cff/cffparse.c (cff_parse): Handle 5-byte numbers byte by byte to avoid alignment issues. * src/cid/cidload (cid_read_subrs): Do nothing if we don't have any subrs. * src/psaux/t1decode.c (t1_decode_parse_charstring): Fix tracing. * src/tools/glnames.py (main): Put `DEFINE_PSTABLES' guard around definition of `ft_get_adobe_glyph_index'. * src/psnames/pstables.h: Regenerated. * src/psnames/psmodule.c: Inlude `pstables.h' twice to get both declaration and definition. * src/truetype/ttgxvar.c (FT_fdot14ToFixed, FT_intToFixed): Fix casting.

bd4b8976	2015-12-20T19:36:04	[type1, psaux] Handle large values of num_subrs correctly (#46692). We now use a hash to map from subr indices to array elements holding the subroutines, if necessary. * include/freetype/internal/t1types.h: Include FT_INTERNAL_HASH_H.

24cee3a8	2015-10-19T23:00:28	[psaux] Fix tracing of negative numbers. Due to incorrect casting negative numbers were shown as very large (positive) integers on 64bit systems. * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_none>: Use division instead of shift.
8edfcbed	2015-10-17T08:11:16	[psaux] Fix heap buffer overflow (#46221). * src/psaux/t1decode.c (t1_decoder_parse_charstring) <operator 12>: Fix limit check.

94152819	2013-05-04T16:40:12	More fixes for clang's `sanitize' feature. * src/base/ftcalc.c (FT_DivFix): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, FT_Vector_Length, FT_Vector_Polarize): Ditto. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. * src/cff/cffload.c (cff_subfont_load): Fix constant. * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, cff_parse_fixed_dynamic): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/cid/cidload.c (cid_get_offset): Ditto. * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.
e3c93015	2013-03-14T11:21:17	/: Use FT_Err_Ok only. This is a purely mechanical conversion.
059bc335	2013-03-14T10:27:35	/: 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.
6b440425	2012-07-18T10:39:18	Fix Savannah bug #36833. * src/psaux/t1decode.c (t1operator_seac): `seac' is not a valid operator if we want metrics only.

143799d4	2011-07-14T07:35:51	[psaux] Fix potential sign extension problems. When shifting right a signed value, it is not defined by the C standard whether one gets a sign extension or not. Use a macro to do an explicit cast from a signed short (assuming that this is 16bit) to an int. * src/psaux/t1decode.c (Fix2Int): New macro. Use it where appropriate.
60f83713	2011-07-14T07:34:12	* src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_callothersubr>: Better handling of subroutine index 0. From Matthias Drochner <M.Drochner@fz-juelich.de>.

c46b1e24	2011-07-08T13:46:42	[psaux] Add better argument check for `callothersubr'. * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_callothersubr>: Reject negative arguments.
ed7d1a59	2010-11-23T19:30:38	* src/psaux/t1decode.c (t1_decoder_parse_charstring): Expand start_point, check_points, add_point, add_point1, close_contour macros. Remove add_contour macro. Return error code from t1_builder_start_point and t1_builder_check_points when there was one (instead of returning 0).

88169b10	2010-05-11T00:03:33	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. (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.
8ea31415	2010-01-08T18:13:02	Fix Savannah bug #28521. Issue #28226 involved a work-around for a font which used the `setcurrentpoint' operator in an invalid way; this operator is only supposed to be used with the result of OtherSubrs, and the font used it directly. The supplied patch removed the block of code which checked this usage entirely. This turns out to be a Bad Thing. If `setcurrentpoint' is being used correctly it should reset the flex flag in the decoder. If we don't do this then the flag never gets reset and we omit any further contours from the glyph (at least until we close the path or similar). * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Handle `flex_state' correctly.

dbe56223	2010-01-05T09:43:01	Make Type 1 `seac' operator work with incremental interface. * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names' if incremental interface is used.
ce412593	2009-12-14T22:32:32	Ignore invalid `setcurrentpoint' operations in Type 1 fonts. This fixes Savannah bug #28226. At least two wild PostScript files of unknown provenance contain Type 1 fonts, apparently converted from TrueType fonts in earlier PDF versions of the files, which use the `setcurrentpoint' operator inappropriately. FreeType currently throws an error in this case, but Ghostscript and Adobe Distiller both accept the fonts and ignore the problem. This commit #ifdefs out the check so PostScript interpreters using FreeType can render these files. The specification says `setcurrentpoint' should only be used to set the point after a `Subr' call, but these fonts use it to set the initial point to (0,0). Unnecessarily so, as they correctly use an `hsbw' operation which implicitly sets the initial point.

11cb8c36	2009-06-22T16:56:47	Use 16.16 format while parsing Type 1 charstrings. This fixes Savannah bug #26867. Previously, only integers have been used which can lead to serious rounding errors. However, fractional values are only used internally; after the charstrings (of either Type 1 or 2) have been processed, the resulting coordinates get rounded to integers currently -- before applying scaling. This should be fixed; at the same time a new load flag should be introduced, to be used in combination with FT_LOAD_NO_SCALE, which indicates that font units are returned in 16.16 format. Similarly, the incremental interface should be extended to allow fractional values for metrics. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift' field. * include/freetype/internal/pshints.h (T1_Hints_SetStemFunc, T1_Hints_SetStem3Func): Use FT_Fixed for coordinates. * src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H. (t1_build_add_point): Always convert fixed to integer. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Use 16.16 format everywhere (except for large integers followed by a `div'). [CAN_HANDLE_NON_INTEGRAL_T1_OPERANDS]: Remove #ifdef and activate code uncoditionally. Add support for random numbers and update remaining code accordingly; this should work now. (t1_operator_seac): Updated. * src/psaux/pshrec.c: Include FT_INTERNAL_CALC_H. (ps_hints_t1stem3, t1_hints_stem): Updated. * src/cid/cidgload.c: Include FT_INTERNAL_CALC_H.

04a7858c	2009-04-30T20:32:31	Make `seac' operator work correctly with incremental interface. SEAC (Single Encoding Accented Characters) are composed of (basically) two indices specifying two other glyphs, and a movement to position the accent properly with respect to the main glyph. To make it work with the incremental interface we now demand that the caller handles the encoding by itself.

33db39e2	2007-06-08T06:30:29	* src/sfnt/sfobjs.c (sfnt_load_face): Undo change from 2007-04-28. Fonts without a cmap must be handled correctly by FreeType (anything else would be a bug). * src/psaux/t1decode.c (t1_decoder_parse_charstrings) [FT_DEBUG_LEVEL_TRACE]: Improve tracing message.
a4d6a1c8	2006-07-19T09:54:56	Move creation of field `buildchar' of T1_DecoderRec out of `t1_decoder_init' and let the caller of `t1_decoder_init' take care of it.

(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.

(should we merge these two services into a single header ??) * include/freetype/internal/ftserv.h: adding FT_FACE_FIND_GLOBAL_SERVICE (used to lookup a service globally, instead of only within the current module) * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: adding the new base function ft_module_get_service

No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

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. (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.

Fix Savannah bug #28521. Issue #28226 involved a work-around for a font which used the `setcurrentpoint' operator in an invalid way; this operator is only supposed to be used with the result of OtherSubrs, and the font used it directly. The supplied patch removed the block of code which checked this usage entirely. This turns out to be a Bad Thing. If `setcurrentpoint' is being used correctly it should reset the flex flag in the decoder. If we don't do this then the flag never gets reset and we omit any further contours from the glyph (at least until we close the path or similar). * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Handle `flex_state' correctly.

Ignore invalid `setcurrentpoint' operations in Type 1 fonts. This fixes Savannah bug #28226. At least two wild PostScript files of unknown provenance contain Type 1 fonts, apparently converted from TrueType fonts in earlier PDF versions of the files, which use the `setcurrentpoint' operator inappropriately. FreeType currently throws an error in this case, but Ghostscript and Adobe Distiller both accept the fonts and ignore the problem. This commit #ifdefs out the check so PostScript interpreters using FreeType can render these files. The specification says `setcurrentpoint' should only be used to set the point after a `Subr' call, but these fonts use it to set the initial point to (0,0). Unnecessarily so, as they correctly use an `hsbw' operation which implicitly sets the initial point.

Use 16.16 format while parsing Type 1 charstrings. This fixes Savannah bug #26867. Previously, only integers have been used which can lead to serious rounding errors. However, fractional values are only used internally; after the charstrings (of either Type 1 or 2) have been processed, the resulting coordinates get rounded to integers currently -- before applying scaling. This should be fixed; at the same time a new load flag should be introduced, to be used in combination with FT_LOAD_NO_SCALE, which indicates that font units are returned in 16.16 format. Similarly, the incremental interface should be extended to allow fractional values for metrics. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift' field. * include/freetype/internal/pshints.h (T1_Hints_SetStemFunc, T1_Hints_SetStem3Func): Use FT_Fixed for coordinates. * src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H.

* src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15. (t1_decoder_parse_charstrings): Operator with opcode 15 pops its two arguments. Handle the case where the pops of an othersubr may be part of a subroutine. Handle unknown othersubrs gracefully: count their operands and let the following pop operators push the operands as the results onto the Type1 stack. Improve handling of setcurrentpoint opcode.

* src/cff/cffgload.c (cff_operator_seac): Fix magnitude of accent offset. Update code similarly to the seac support for Type 1 fonts. (cff_decoder_parse_charstrings) <cff_op_endchar>: Fix magnitude of accent offset. Don't hint glyphs twice if seac is emulated. <cff_op_flex>: Assign correct point tags. * docs/CHANGES: Updated. * src/type1/t1parse.c (T1_Get_Private_Dict): Use FT_MEM_MOVE, not FT_MEM_COPY, for copying the private dict. * src/type1/t1load.c (parse_subrs): Assign number of subrs only in first run. (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.

* include/freetype/internal/services/svpsname.h (added), include/freetype/internal/psnames.h (removed), include/freetype/internal/internal.h (FT_SERVICE_POSTSCRIPT_NAMES): added new service to handle glyph name dictionaries, replacing the old internal header named "psnames.h" by "services/svpsname.h" note that this is different from "services/svpostnm.h" which only handles the retrieval of Postscript font name for a given face. (should we merge these two services into a single header ??) * include/freetype/internal/ftserv.h: adding FT_FACE_FIND_GLOBAL_SERVICE (used to lookup a service globally, instead of only within the current module) * include/freetype/internal/ftobjs.h, src/base/ftobjs.c: adding the new base function ft_module_get_service
