FreeTypeFont

Font implementation based on FreeType.

Constructors

this this(FontFileItem item, int size): need to call create() after construction to initialize font

Destructor

~this ~this(): do cleanup

Members

Functions

checkpoint void checkpoint(): clear usage flags for all entries
cleanup void cleanup(): removes entries not used after last call of checkpoint() or cleanup()
clear void clear(): cleanup resources
clearGlyphCache void clearGlyphCache(): clears glyph cache
create bool create(): load font files
findGlyph bool findGlyph(dchar code, dchar def_char, FT_UInt index, FreeTypeFontFile file): find glyph index for character
getCharGlyph Glyph* getCharGlyph(dchar ch, bool withImage): Undocumented in source. Be warned that the author may not have intended to support it.
getGlyphIndex uint getGlyphIndex(dchar code): Undocumented in source. Be warned that the author may not have intended to support it.
