Modules

blob 🔒

Blobs of font bytes.

cache 🔒

Tables parsed once for a font and kept.

format 🔒

Font format detection.

source 🔒

Font data sources.

tables 🔒

Table validation, caching and access.

Structs

FeatureVarsStorage 🔒

Lazy atomic storage for feature variation selections.

Font

A font at one location in its design space.

InstanceBuilder

Builder for configuring a font instance.

LocationCaches 🔒

Caches for one location of a font of any kind.

SfntCaches 🔒

Caches for an SFNT font, with each table parsed once per font.

SfntLocation 🔒

Caches for one location of an SFNT font.

SharedFont 🔒

The state every instance of a font shares.

SharedFontRepr 🔒

StandaloneCffData 🔒

Type1Data 🔒

A Type 1 font and the axes of its design space, if it has one.

VariedInstance 🔒

What a location away from the default carries.

VariedSfnt 🔒

Caches for a varied SFNT instance.

VariedType1 🔒

A Type 1 multiple master font at a location.

Enums

Kind

The underlying type of a font.

KindRepr 🔒

The underlying type of a font.

Repr 🔒

VariedKind 🔒

Caches for a varied instance, by font kind.

Constants

CACHED_SUBFONTS 🔒

The number of CFF subfonts a font keeps once parsed. A subfont past them is parsed again whenever a glyph needs it.

MAX_INLINE_COORDS 🔒

Maximum number of coordinates we store inline. Chosen to maximize the number of coords without growing the storage: a SmallVec is a capacity alongside a union of the inline array and the heap pointer, so twelve two byte coords are the most that fit in 32 bytes.

MAX_PRECOMPUTED_SCALARS 🔒

SOURCE_ABSENT 🔒

The kept answer for a glyph source the font does not have.

SOURCE_PRESENT 🔒

The kept answer for a glyph source the font has.

Functions

cid_table 🔒

Builds the table from each CID to its glyph, keeping the first glyph for a CID.

clear_if_all_zeroes 🔒

Empties coords if every coordinate is zero. This lets the default instance skip variation processing behind a plain is_empty check.

named_instance_variations 🔒

scalars_with 🔒

Returns up to MAX_PRECOMPUTED_SCALARS scalars from count, filled by compute, which returns how many it wrote.

set_variations 🔒

Helper for setting variations.

store_scalars 🔒

Returns the region scalars of store at coords, or none without a store.

Type Aliases

CoordStorage 🔒

SubfontCache 🔒

A cache of CFF subfonts at one location, each parsed when a glyph first needs it.
