Priyesh Kumar 53be1753 2020-07-28T07:33:40 Fix `-Wformat' compiler warnings. * src/*: Fix format specifiers. * builds/unix/ftsystem.c (FT_Stream_Open): Ditto.
Werner Lemberg 2eb8f886 2020-07-06T09:21:03 [psaux] Improve `t1_decoder_parse_metrics' (#58646). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function to handle `op_callsubr' and `op_return'.
Werner Lemberg 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'.
David Turner 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.
Werner Lemberg 6e49dff0 2020-02-21T20:57:52 [psaux] Make `t1_decoder_parse_metrics' handle `op_div' (#57519). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function.

Nikhil Ramakrishnan 78d85b9c 2018-06-04T18:42:29 Restore missing comment lines and other minor fixes
Werner Lemberg 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.

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.

Werner Lemberg 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.

Ken Sharp 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.
Ken Sharp 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.

Ken Sharp 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.
Ken Sharp 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.

Werner Lemberg 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.

Werner Lemberg 86fa2ebc 2009-06-19T14:56:26 Improve debug messages for Type1 charstrings. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Emit newlines after instructions. Prettify output.
Ralph Giles 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.
Werner Lemberg e85baf4f 2009-01-12T20:01:10 Fix stdlib dependencies. Problem reported by Mickey Gabel <mickey@monfort.co.il>. * include/freetype/config/ftstdlib.h (ft_exit): Removed.

Werner Lemberg 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.
Werner Lemberg 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.

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.
Werner Lemberg c9114b99 2005-02-10T08:18:27 * builds/unix/freetype-config.in: Add new flag `--ftversion' to return the FreeType version. Suggested by George Williams <gww@silcom.com>. * docs/CHANGES: Updated. * src/otvalid/otvmod.c (otv_validate): Deallocate arrays in case of error. Reported by YAMANO-UCHI Hidetoshi <mer@din.or.jp>. * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_closepath>: Accept `T1_Parse_Have_Moveto' state also which can happen in empty glyphs. Reported by Ian Brown <ian.brown@printsoft.de>.
Werner Lemberg efd4e877 2004-05-13T12:59:59 * include/freetype/internal/psaux.h (T1_ParseState): New enumeration. (T1_BuilderRec): Replace `path_begun' with `parse_state'. Remove `error'. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Replace `Memory_Error' with `Fail' and update all users. Don't use `builder->error'.

(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.

David Turner 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_.
