Fields

data: Vec<u8>

encoding: [Option<String>; 256]

widths: [f64; 256]

cmap: HashMap<u32, u16>

cmap_is_unicode: bool

Whether the cmap maps Unicode values (true) or re-encoded char codes (false). Non-Unicode cmaps come from (1,0) Mac Roman or (3,0) Symbol subtables in subset fonts — the encoding→unicode→cmap lookup path must be skipped.

post_name_to_gid: HashMap<String, u16>

Glyph name → GID mapping from the post table (for ligatures and other glyphs not reachable via Unicode cmap lookup).

units_per_em: f64

to_unicode: HashMap<u16, u32>

Char code → Unicode mapping from /ToUnicode CMap (for gNNNN glyph names in substituted fonts where AGL lookup fails).

identity_gid: bool

When true, char codes map directly to GIDs (identity mapping). Set for symbolic TrueType fonts without an explicit /Encoding, where the cmap subtable maps to misleading Unicode values (re-encoded fonts).

gid_hex: bool

When true, gNNNN glyph names in the encoding use hexadecimal GIDs (e.g. g003a = GID 58). Set when any gNNNN name contains hex letters (a-f). When false, gNNNN names use decimal (e.g. g1863 = GID 1863).
