It * scales the glyph images and their metrics to a requested size, and it * rasterizes the glyph images to produce pixel or subpixel alpha coverage * bitmaps. * * Note that FreeType is _not_ a text layout engine. You have to use * higher-level libraries like HarfBuzz, Pango, or ICU for that. * * Note also that FreeType does _not_ perform alpha blending or * compositing the resulting bitmaps or pixmaps by itself. Use your * favourite graphics library (for example, Cairo or Skia) to further * process FreeType's output. * */ /************************************************************************** * * @section: * header_inclusion * * @title: * FreeType's header inclusion scheme * * @abstract: * How client applications should include FreeType header files. * * @description: * To be as flexible as possible (and for historical reasons), you must * load file `ft2build.h` first before other header files, for example * * ``` * #include <ft2build.h> * * #include <freetype/freetype.h> * #include <freetype/ftoutln.h> * ``` */ /************************************************************************** * * @section: * user_allocation * * @title: * User allocation * * @abstract: * How client applications should allocate FreeType data structures. * * @description: * FreeType assumes that structures allocated by the user and passed as * arguments are zeroed out except for the actual data. In other words, * it is recommended to use `calloc` (or variants of it) instead of * `malloc` for allocation. * */ /************************************************************************** * * @section: * font_testing_macros * * @title: * Font Testing Macros * * @abstract: * Macros to test various properties of fonts. * * @description: * Macros to test the most important font properties. * * It is recommended to use these high-level macros instead of directly * testing the corresponding flags, which are scattered over various * structures. * * @order: * FT_HAS_HORIZONTAL * FT_HAS_VERTICAL * FT_HAS_KERNING * FT_HAS_FIXED_SIZES * FT_HAS_GLYPH_NAMES * FT_HAS_COLOR * FT_HAS_MULTIPLE_MASTERS * FT_HAS_SVG * FT_HAS_SBIX * FT_HAS_SBIX_OVERLAY * * FT_IS_SFNT * FT_IS_SCALABLE * FT_IS_FIXED_WIDTH * FT_IS_CID_KEYED * FT_IS_TRICKY * FT_IS_NAMED_INSTANCE * FT_IS_VARIATION * */ /************************************************************************** * * @section: * library_setup * * @title: * Library Setup * * @abstract: * Functions to start and end the usage of the FreeType library. * * @description: * Functions to start and end the usage of the FreeType library. * * Note that @FT_Library_Version and @FREETYPE_XXX are of limited use * because even a new release of FreeType with only documentation * changes increases the version number. * * @order: * FT_Library * FT_Init_FreeType * FT_Done_FreeType * * FT_Library_Version * FREETYPE_XXX * */ /************************************************************************** * * @section: * face_creation * * @title: * Face Creation * * @abstract: * Functions to manage fonts. * * @description: * The functions and structures collected in this section operate on * fonts globally. * * @order: * FT_Face * FT_FaceRec * FT_FACE_FLAG_XXX * FT_STYLE_FLAG_XXX * * FT_New_Face * FT_Done_Face * FT_Reference_Face * FT_New_Memory_Face * FT_Face_Properties * FT_Open_Face * FT_Open_Args * FT_OPEN_XXX * FT_Parameter * FT_Attach_File * FT_Attach_Stream * */ /************************************************************************** * * @section: * sizing_and_scaling * * @title: * Sizing and Scaling * * @abstract: * Functions to manage font sizes. * * @description: * The functions and structures collected in this section are related to * selecting and manipulating the size of a font globally. * * @order: * FT_Size * FT_SizeRec * FT_Size_Metrics * * FT_Bitmap_Size * * FT_Set_Char_Size * FT_Set_Pixel_Sizes * FT_Request_Size * FT_Select_Size * FT_Size_Request_Type * FT_Size_RequestRec * FT_Size_Request * * FT_Set_Transform * FT_Get_Transform * */ /************************************************************************** * * @section: * glyph_retrieval * * @title: * Glyph Retrieval * * @abstract: * Functions to manage glyphs. * * @description: * The functions and structures collected in this section operate on * single glyphs, of which @FT_Load_Glyph is most important. * * @order: * FT_GlyphSlot * FT_GlyphSlotRec * FT_Glyph_Metrics * * FT_Load_Glyph * FT_LOAD_XXX * FT_LOAD_TARGET_MODE * FT_LOAD_TARGET_XXX * * FT_Render_Glyph * FT_Render_Mode * FT_Get_Kerning * FT_Kerning_Mode * FT_Get_Track_Kerning * */ /************************************************************************** * * @section: * character_mapping * * @title: * Character Mapping * * @abstract: * Functions to manage character-to-glyph maps. * * @description: * This section holds functions and structures that are related to * mapping character input codes to glyph indices. * * Note that for many scripts the simplistic approach used by FreeType * of mapping a single character to a single glyph is not valid or * possible!
