typedef uint16_t BLGlyphId

Glyph identifier is an index to a glyph stored in a font.

GlyphId is always an unsigned 16-bit integer as used by TrueType and OpenType fonts. There are some libraries that use 32-bit integers for Glyph indexes, but values above 65535 are never used in practice as font's generally do not have the ability to index more than 65535 glyphs (excluding null glyph).

BLTextEncoding : uint32_tenum

Text encoding.

ConstantDescription
