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. * */ /*************************************************************************/ /*************************************************************************/ /* */ /* B A S I C T Y P E S */ /* */ /*************************************************************************/ /*************************************************************************/ /************************************************************************** * * @section: * base_interface * * @title: * Base Interface * * @abstract: * The FreeType~2 base font interface. * * @description: * This section describes the most important public high-level API * functions of FreeType~2. * * @order: * FT_Library * FT_Face * FT_Size * FT_GlyphSlot * FT_CharMap * FT_Encoding * FT_ENC_TAG * * FT_FaceRec * * FT_FACE_FLAG_SCALABLE * FT_FACE_FLAG_FIXED_SIZES * FT_FACE_FLAG_FIXED_WIDTH * FT_FACE_FLAG_HORIZONTAL * FT_FACE_FLAG_VERTICAL * FT_FACE_FLAG_COLOR * FT_FACE_FLAG_SFNT * FT_FACE_FLAG_CID_KEYED * FT_FACE_FLAG_TRICKY * FT_FACE_FLAG_KERNING * FT_FACE_FLAG_MULTIPLE_MASTERS * FT_FACE_FLAG_VARIATION * FT_FACE_FLAG_GLYPH_NAMES * FT_FACE_FLAG_EXTERNAL_STREAM * FT_FACE_FLAG_HINTER * FT_FACE_FLAG_SVG * FT_FACE_FLAG_SBIX * FT_FACE_FLAG_SBIX_OVERLAY * * 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 * * FT_STYLE_FLAG_BOLD * FT_STYLE_FLAG_ITALIC * * FT_SizeRec * FT_Size_Metrics * * FT_GlyphSlotRec * FT_Glyph_Metrics * FT_SubGlyph * * FT_Bitmap_Size * * FT_Init_FreeType * FT_Done_FreeType * * FT_New_Face * FT_Done_Face * FT_Reference_Face * FT_New_Memory_Face * FT_Face_Properties * FT_Open_Face * FT_Open_Args * FT_Parameter * FT_Attach_File * FT_Attach_Stream * * 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 * FT_Load_Glyph * FT_Get_Char_Index * FT_Get_First_Char * FT_Get_Next_Char * FT_Get_Name_Index * FT_Load_Char * * FT_OPEN_MEMORY * FT_OPEN_STREAM * FT_OPEN_PATHNAME * FT_OPEN_DRIVER * FT_OPEN_PARAMS * * FT_LOAD_DEFAULT * FT_LOAD_RENDER * FT_LOAD_MONOCHROME * FT_LOAD_LINEAR_DESIGN * FT_LOAD_NO_SCALE * FT_LOAD_NO_HINTING * FT_LOAD_NO_BITMAP * FT_LOAD_SBITS_ONLY * FT_LOAD_NO_AUTOHINT * FT_LOAD_COLOR * * FT_LOAD_VERTICAL_LAYOUT * FT_LOAD_IGNORE_TRANSFORM * FT_LOAD_FORCE_AUTOHINT * FT_LOAD_NO_RECURSE * FT_LOAD_PEDANTIC * * FT_LOAD_TARGET_NORMAL * FT_LOAD_TARGET_LIGHT * FT_LOAD_TARGET_MONO * FT_LOAD_TARGET_LCD * FT_LOAD_TARGET_LCD_V * * FT_LOAD_TARGET_MODE * * FT_Render_Glyph * FT_Render_Mode * FT_Get_Kerning * FT_Kerning_Mode * FT_Get_Track_Kerning * FT_Get_Glyph_Name * FT_Get_Postscript_Name * * FT_CharMapRec * FT_Select_Charmap * FT_Set_Charmap * FT_Get_Charmap_Index * * FT_Get_FSType_Flags * FT_Get_SubGlyph_Info * * FT_Face_Internal * FT_Size_Internal * FT_Slot_Internal * * FT_FACE_FLAG_XXX * FT_STYLE_FLAG_XXX * FT_OPEN_XXX * FT_LOAD_XXX * FT_LOAD_TARGET_XXX * FT_SUBGLYPH_FLAG_XXX * FT_FSTYPE_XXX * * FT_HAS_FAST_GLYPHS * */ /************************************************************************** * * @struct: * FT_Glyph_Metrics * * @description: * A structure to model the metrics of a single glyph.
