Version 2.10.0 was released back in March. We should probably pick it up.
CHANGES BETWEEN 2.9.1 and 2.10
I. IMPORTANT CHANGES
- A bunch of new functions has been added to access and process COLR/CPAL data of OpenType fonts with color-layered glyphs. FT_Palette_Data_Get Retrieve color palette data. FT_Palette_Select Select and activate a color palette for color-layered glyphs. FT_Palette_Set_Foreground_Color Set text foreground color for palette index 0xFFFF. FT_Get_Color_Glyph_Layer Get color layers for a given glyph (using an interator object). FT_Bitmap_Blend Blend one bitmap onto another with a given color. - An experimental feature is the new behaviour of the `FT_LOAD_COLOR' load flag for color-layered glyphs: Internally it sets a flag so that if `FT_Render_Glyph' is called with `FT_RENDER_MODE_NORMAL' (or `FT_Load_Glyph' with `FT_LOAD_RENDER'), a default blending of the color glyph layers will happen automatically for convenience. - As a GSoC 2018 project, Nikhil Ramakrishnan completely overhauled and modernized the API reference.
- The logic for computing the global ascender, descender, and height of OpenType fonts has been slightly adjusted for consistency. . If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection' field) in the `OS/2' table is set, use the `sTypo' fields in `OS/2' unconditionally. . Otherwise use the metrics data from the `hhea' table (if not zero). . Otherwise use the `sTypo' fields from the `OS/2' table (if not zero). . Otherwise use the `usWin' data from the `OS/2' table as a last resort. Variable fonts will apply the `MVAR' deltas to whichever metrics were picked. - `TT_Set_MM_Blend' could fail if call repeatedly with the same arguments. - The precision of handling deltas in Variation Fonts has been increased. The problem did only show up with multidimensional designspaces. - New function `FT_Library_SetLcdGeometry' to set up the geometry of LCD subpixels. - FreeType now uses the `defaultChar' property of PCF fonts to set the glyph for the undefined character at glyph index 0 (as FreeType already does for all other supported font formats). As a consequence, the order of glyphs of a PCF font if accessed with FreeType can be different now compared to previous versions. This change doesn't affect PCF font access with cmaps. - `FT_Select_Charmap' has been changed to allow parameter value `FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT formats to access built-in cmaps that don't have a predefined `FT_Encoding' value. - A previously reserved field in the `FT_GlyphSlotRec' structure now holds the glyph index. - On Win32 platforms, the use of `_DLL' to build the library has been replaced with `DLL_EXPORT' and `DLL_IMPORT'. - The usual round of fuzzer bug fixes to better reject malformed fonts. - `FT_Outline_New_Internal' and `FT_Outline_Done_Internal' have been removed. These two functions were public by oversight only and were never documented. - A new function `FT_Error_String' returns descriptions of error codes if configuration macro FT_CONFIG_OPTION_ERROR_STRINGS is defined. - `FT_Set_MM_WeightVector' and `FT_Get_MM_WeightVector' are new functions limited to Adobe MultiMaster fonts to directly set and get the weight vector. - Support for Position Independent Code as needed by systems that prohibit automatic address fixups, such as BREW, has been removed. [Compilation with modern compilers that use flags like `-fPIC' or `-fPIE' is not affected.] - The `ftdump' demo program has new options `-c' and `-C' to display charmaps in compact and detailed format, respectively. Option `-V' has been removed. - The `ftview', `ftstring', and `ftgrid' demo programs use a new command line option `-d' to specify the program window's width, height, and color depth. - The `ftview' demo program now displays red boxes for zero-width glyphs. - `ftglyph' has limited support to display fonts with color-layered glyphs. This will be improved later on. - `ftgrid' can now display bitmap fonts also. - The `ttdebug' demo program has a new option `-f' to select a member of a TrueType collection (TTC). - Other various improvements to the demo programs.
