Ben Wagner c4fe77c3 2023-04-17T11:17:16 [truetype] tt_size_reset_height to take FT_Size The `MetricsVariations` `FT_Size_Reset_Func` is defined to take an `FT_Size`. Because `tt_size_reset_height` is to be used as such a function, it must also take an `FT_Size` instead of a `TT_Size`. Even though the pointers passed will be the same at runtime, calling a function through a pointer of a different type from the original function pointer type is undefined behavior. This may be caught at runtime by Control Flow Integrity with something like clang's `cfi-icall`. Issue: https://crbug.com/1433651 * src/truetype/ttobjs.h (tt_size_reset_height): take `FT_Size` * src/truetype/ttobjs.c (tt_size_reset_height): take `FT_Size` and update documentation
Ben Wagner e78e2d29 2023-04-06T11:16:29 [sfnt, truetype] Add `size_reset` to `MetricsVariations`. This is a generalization of commit ``` commit e6699596af5c5d6f0ae0ea06e19df87dce088df8 Author: Werner Lemberg <wl@gnu.org> Date: Thu Feb 2 11:38:04 2017 +0100 [truetype] Fix MVAR post-action handling. ``` It is also possible for plain `CFF ` style fonts to contain an `fvar` and `MVAR` table and use `cff_metrics_adjust`. `tt_size_reset` should only be called with `TT_Size` and never with `CFF_Size`. Allow the "metrics-variations" service to specify the correct function (if any) to reset `FT_Size`s after adjusting metrics. * src/truetype/ttobjs.c (tt_size_reset): Split off some functionality into... (tt_size_reset_height): ... this new function. * src/truetype/ttdriver.c (tt_service_metrics_variations): Add `size_reset`. (tt_size_select, tt_size_request): Updated. * src/truetype/ttobjs.h: Updated. * include/freetype/internal/services/svmetric.h (MetricsVariations): Add `size_reset`. (FT_DEFINE_SERVICE_METRICSVARIATIONSREC): Updated. * include/freetype/internal/tttypes.h (TT_FaceRec_): Rename `var` to `tt_var` and add `face_var`. * src/cff/cffdrivr.c (cff_service_metrics_variations): Add `size_reset`. (cff_hadvance_adjust, cff_metrics_adjust): Updated. * src/cff/cffobjs.c (cff_face_init): Use `face_var`. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `face_var`. * src/sfnt/ttmtx.c (tt_face_get_metrics): Use `tt_var`. * src/truetype/ttgxvar.c (tt_size_reset_iterator): Renamed to... (ft_size_reset_iterator): ... this new function. Call `size_reset`. (tt_apply_mvar): Pass `size_reset` to `ft_size_reset_iterator`. Fixes #1211

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.

Behdad Esfahbod 531d463a 2015-01-14T17:46:55 [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. Previously the code had stipulation for using a per-TT_Size exec context if `size->debug' was true. But there was no way that `size->debug' could *ever* be true. As such, the code was always using the singleton `TT_ExecContext' that was stored in `TT_Driver'. This was, clearly, not threadsafe. With this patch, loading glyphs from different faces from different threads doesn't crash in the bytecode loader code. * src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member. (TT_DriverRec): Remove `context' member. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove `TT_ExecContext' code related to a global `TT_Driver' object. (tt_driver_done): Don't remove `TT_ExecContext' object here but ... (tt_size_done_bytecode): ... here. (tt_driver_init): Don't create `TT_ExecContext' object here but ... (tt_size_init_bytecode): ... here, only on demand. * src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug code. (TT_New_Context): Remove `TT_ExecContext' code related to a global `TT_Driver' object. * src/truetype/ttinterp.h: Updated. * src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated.
Alexei Podtelezhnikov 7e83f068 2014-10-14T23:03:56 [truetype] Limit delta shift range. The legal range for delta shift is zero through six. Negative values are illegal according to https://developer.apple.com/fonts/TrueType-Reference-Manual/RM04/Chap4.html#delta%20shift * src/truetype/ttobjs.h (delta_shift, delta_base): Make unsigned. * src/truetype/ttinterp.h (DO_SDS): Throw an error if delta_shift out of range. (Ins_DELTAP, Ins_DELTAC): Optimize for legal delta_shift.
Werner Lemberg 441b3f38 2014-07-13T02:28:14 [truetype] Improve handling of buggy `prep' tables. In case of an error in the `prep' table, no longer try to execute it again and again. This makes FreeType handle endless loops in buggy fonts much faster. * src/truetype/ttobjs.h (TT_SizeRec): The fields `bytecode_ready' and `cvt_ready' are now negative if not initialized yet, otherwise they indicate the error code of the last run. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, tt_size_done_bytecode, tt_size_init_bytecode, tt_size_ready_bytecode, tt_size_init, tt_size_done, tt_size_reset): Updated. * src/truetype/ttgload.c (tt_loader_init): Updated. * src/truetype/ttinterp.c (TT_RunIns): Force reexecution of `fpgm' and `prep' only if we are in the `glyf' table.
Werner Lemberg f04951af 2013-05-17T13:51:07 [truetype] Add `interpreter-version' property. This makes the option TT_CONFIG_OPTION_SUBPIXEL_HINTING controllable at runtime. * src/truetype/ttdriver.c: Include FT_TRUETYPE_DRIVER_H. (tt_property_set, tt_property_get): Fill templates. * src/truetype/ttobjs.h (TT_DriverRec): Add `interpreter_version' member.

(SUBPIXEL_HINTING): New macro to check `interpreter_version' flag. Update all affected functions to use it. Use TT_INTERPRETER_VERSION_XXX where appropriate. * src/truetype/ttobjs.c: Include FT_TRUETYPE_DRIVER_H. (tt_driver_init): Initialize `interpreter_version'. * src/truetype/ttsubpix.c: Include FT_TRUETYPE_DRIVER_H. Use TT_INTERPRETER_VERSION_XXX where appropriate.

Infinality 79e36bae 2012-06-18T10:36:06 [truetype] Support subpixel hinting. This is the large, famous `Infinality' patch to support ClearType bytecode which has been available from http://www.infinality.net/blog/ for some time, and which has been refined over the last years. While still experimental, it is now mature enough to be included directly into FreeType. Most of the code is based on the ClearType whitepaper written by Greg Hitchcock http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx which gives a detailed overview of the necessary changes to the Microsoft rasterizer so that older fonts are supported. However, a lot of details are still missing, and this patches provides a framework to easily handle rendering issues down to the glyph level of certain fonts. Note that ClearType support is not completely implemented! In particular, full support for the options `compatible_widths', `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode instruction) is missing. * src/truetype/ttsubpix.c: New file, providing code to handle `tweaks', this is, rules for certain glyphs in certain fonts (including wildcards) which need a special treatment. * src/truetype/ttsubpix.h: New file, holding the tweaking rules. * include/freetype/config/ftoption.h, src/devel/ftoption.h (TT_CONFIG_OPTION_SUBPIXEL_HINTING): New macro. * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID, FT_PIX_ROUND_GRID, FT_PIX_CEIL_GRID): New macros. * src/truetype/truetype.c [TT_USE_BYTECODE_INTERPRETER]: Include `ttsubpix.c'. * src/truetype/ttgload.c: Include `ttsubpix.h'.

(TT_Process_Simple_Glyph): Compensate emboldening if necessary. (compute_glyph_metrics): Handle `compatible widths' option. (tt_loader_init): Handle ClearType GETINFO information bits. * src/truetype/rules.mk (TT_DRC_SRC): Updated. * src/truetype/ttinterp.c: Include `ttsubpix.h'. [Where necessary, changes below are guarded by TT_CONFIG_OPTION_SUBPIXEL_HINTING.] (Direct_Move, Direct_Move_X): Extended. (Round_None, Round_To_Grid, Round_To_Half_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid, Round_Super, Round_Super_45, SetSuperRound): Add parameter to handle the number of grid lines per pixel.

David Turner 8b6db86b 2003-08-17T22:09:14 * include/freetype/config/ftoption.h, devel/ftoption.h, include/freetype/internal/ftobjs.h, include/freetype/internal/tttypes.h, src/truetype/ttinterp.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h: changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead, the same effect can be used by setting a debug-hook with FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()
Graham Asher 3ea859f6 2003-04-25T11:40:46 Added the unpatented hinting system, which is compiled only if TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING is defined in ftoption.h

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_.

Please check ftmoderr.h for more details. * include/freetype/internal/cfferrs.h, include/freetype/internal/tterrors.h, include/freetype/internal/t1errors.h: Removed. Replaced with files local to the module. All extra error codes have been moved to `fterrors.h'. * src/sfnt/ttpost.h: Move error codes to `fterrors.h'. * src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h, src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h, src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h, src/smooth/ftsmerrs.h, src/truetype/tterrors.h, src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the error names for the module it belongs to. * include/freetype/ftmoderr.h: New file, defining the module error offsets. Its structure is similar to `fterrors.h'. * include/freetype/fterrors.h (FT_NOERRORDEF): New macro. (FT_ERRORDEF): Redefined to use module error offsets.

Werner Lemberg cc069beb 2000-12-08T16:17:16 cleanups
David Turner 19ed8afe 2000-12-08T02:42:29 - updated all source files to adhere to the new inclusion scheme - the CFF loader now loads the encodings and charset tables though doesn't use them for now
Werner Lemberg 4b68007b 2000-11-07T06:30:29 Complementing David's changes with formatting, adding documentation, etc. More `*'-convention formatting, adding the `a' resp. `an' prefix to variables.
David Turner f96594fa 2000-11-06T23:07:51 integrated Yamano-Uchi changes to the base source code. However, I've made a few modifications: - there is no new field named "driver" in "FT_SizeRec" - the new fields in "TT_SizeRec" are: strike_index :: value 0xFFFF means "no sbit strike selected" strike_metrics :: the FT_Size_Metrics structure corresponding to the currently selected strike - the code in "ttload.c" has been somewhat cleaned up too thanks a lot, Y-U !! - David
Werner Lemberg dc72aff4 2000-11-04T08:33:38 Finishing David's latest changes (there were some errors in it).
David Turner 76a5f623 2000-11-04T01:55:49 major reformatting of the sources: FT_EXPORT_DEF => FT_EXPORT FT_EXPORT_FUNC => FT_EXPORT_DEF BASE_DEF => FT_BASE BASE_FUNC => FT_BASE_DEF LOCAL_DEF => FT_LOCAL LOCAL_FUNC => FT_LOCAL_DEF LOCAL_FUNC_X => FT_CALLBACK_DEF LOCAL_DEF_X => FT_CALLBACK_TABLE FT_CPLUSPLUS => FT_CALLBACK_TABLE_DEF
David Turner c5cdf8bc 2000-07-27T21:40:22 re-adding a "unix-dev.mk". Debugging libtool output is just too much of a pain for me, I prefer a good old static lib without optimizations :-) "make devel" is back on Unix then..
Werner Lemberg 321cd27d 2000-07-27T11:20:20 Removing compiler warnings about unused portions of code. Now unix.in uses absolute paths also to overcome problems with libtool. To do that in a consistent way I had to modify the rules how to handle $OBJ_DIR (and consequently $LIB_DIR): You should set $OBJ_DIR explicitly on the command line (or environment).
Werner Lemberg 5811c7c3 2000-07-02T13:53:16 Formatting. Fixed some errors which prevented compiling.
David Turner c3128615 2000-06-23T05:02:13 bugfixes in the Type1 drivers
David Turner f0df85ba 2000-06-22T00:17:42 - MAJOR INTERNAL REDESIGN: A lot of internal modifications have been performed lately on the source in order to provide the following enhancements: - more generic module support: The FT_Module type is now defined to represent a handle to a given module. The file <freetype/ftmodule.h> contains the FT_Module_Class definition, as well as the module-loading public API The FT_Driver type is still defined, and still represents a pointer to a font driver. Note that FT_Add_Driver is replaced by FT_Add_Module, FT_Get_Driver by FT_Get_Module, etc.. - support for generic glyph image types: The FT_Renderer type is a pointer to a module used to perform various operations on glyph image. Each renderer is capable of handling images in a single format (e.g. ft_glyph_format_outline). Its functions are used to: - transform an glyph image - render a glyph image into a bitmap - return the control box (dimensions) of a given glyph image The scan converters "ftraster.c" and "ftgrays.c" have been moved to the new directory "src/renderer", and are used to provide two default renderer modules. One corresponds to the "standard" scan-converter, the other to the "smooth" one. The current renderer can be set through the new function FT_Set_Renderer. The old raster-related function FT_Set_Raster, FT_Get_Raster and FT_Set_Raster_Mode have now disappeared, in favor of the new: FT_Get_Renderer FT_Set_Renderer see the file <freetype/ftrender.h> for more details.. These changes were necessary to properly support different scalable formats in the future, like bi-color glyphs, etc.. - glyph loader object: A new internal object, called a 'glyph loader' has been introduced in the base layer. It is used by all scalable format font drivers to load glyphs and composites. This object has been created to reduce the code size of each driver, as each one of them basically re-implemented its functionality. See <freetype/internal/ftobjs.h> and the FT_GlyphLoader type for more information.. - FT_GlyphSlot had new fields: In order to support extended features (see below), the FT_GlyphSlot structure has a few new fields: linearHoriAdvance: this field gives the linearly scaled (i.e. scaled but unhinted) advance width for the glyph, expressed as a 16.16 fixed pixel value. This is useful to perform WYSIWYG text. linearVertAdvance: this field gives the linearly scaled advance height for the glyph (relevant in vertical glyph layouts only). This is useful to perform WYSIWYG text. Note that the two above field replace the removed "metrics2" field in the glyph slot. advance: this field is a vector that gives the transformed advance for the glyph. By default, it corresponds to the advance width, unless FT_LOAD_VERTICAL_LAYOUT was specified when calling FT_Load_Glyph or FT_Load_Char bitmap_left: this field gives the distance in integer pixels from the current pen position to the left-most pixel of a glyph image WHEN IT IS A BITMAP. It is only valid when the "format" field is set to "ft_glyph_format_bitmap", for example, after calling the new function FT_Render_Glyph. bitmap_top: this field gives the distance in integer pixels from the current pen position (located on the baseline) to the top-most pixel of the glyph image WHEN IT IS A BITMAP. Positive values correspond to upwards Y. loader: this is a new private field for the glyph slot. Client applications should not touch it.. - support for transforms and direct rendering in FT_Load_Glyph: Most of the functionality found in <freetype/ftglyph.h> has been moved to the core library. Hence, the following: - a transform can be specified for a face through FT_Set_Transform. this transform is applied by FT_Load_Glyph to scalable glyph images (i.e. NOT TO BITMAPS) before the function returns, unless the bit flag FT_LOAD_IGNORE_TRANSFORM was set in the load flags.. - once a glyph image has been loaded, it can be directly converted to a bitmap by using the new FT_Render_Glyph function. Note that this function takes the glyph image from the glyph slot, and converts it to a bitmap whose properties are returned in "face.glyph.bitmap", "face.glyph.bitmap_left" and "face.glyph.bitmap_top". The original native image might be lost after the conversion. - when using the new bit flag FT_LOAD_RENDER, the FT_Load_Glyph and FT_Load_Char functions will call FT_Render_Glyph automatically when needed.
David Turner f9b8dec4 2000-06-16T19:34:52 major reformatting of the modules source code in order to get rid of most of the basic types redefinitions (i.e. FT_Int instead of "FT_Int", etc..) The format-specific prefixs like "TT_", "T1_", "T2_" & 'CID_" are now only used in relevant structures.. fixed Werner's fix to t2gload.c :-) other small bug fixes
Werner Lemberg 78575dc0 2000-06-12T19:36:41 A lot of formatting. Added more tracing levels. More Makefile fixes. Minor other changes.
Werner Lemberg e1d5dd78 2000-06-07T04:48:12 Moved all *errors.h header files to include/freetype/internal for consistency. Removed unused error message.
David Turner e49ab25c 2000-05-16T23:44:38 formatting - removed trailing spaces
David Turner 4f2c5544 2000-05-12T10:19:41 additional changes, this time in order to pass extra parameters to font drivers when creating a new face object. The FT_Open_Args structure has been changed to simplify its use and allow generic parameters too..
David Turner efce08d6 2000-05-11T18:23:52 major re-organisation of the FreeType 2 directory hierarchy
David Turner 7f7aadf4 2000-03-13T12:57:27 finished moving all configuration macros to "config/ftoption.h"
David Turner 08fdac98 2000-02-21T16:01:33 fixed a bug in the glyph loader that caused a memory block to be freed twice. Also performed changes to use the new glyph zone object that has appeared in ftobjs.h
David Turner 8f43c714 2000-02-02T12:16:19 A major refresh of the TrueType driver : - some #ifdefs were included in order to _not_ compile support for the bytecode interpreter when FT_CONFIG_OPTION_BYTECODE_INTERPRETER is not defined in "ttconfig.h" - the glyph loader has been seriously re-designed. It is now smaller, simpler and should load composites a bit faster - works with the TrueType debugger
