Struct GidMap 

pub struct GidMap { /* private fields */ }

How the glyphs of a font were renumbered by subsetting.

Old glyph ID to new. Everything PDF-side that named a glyph — /W, /ToUnicode, and the char codes of an Identity-H content stream — has to be looked up through this.

Implementations

impl GidMap

pub fn from_pairs(pairs: impl IntoIterator<Item = (u16, u16)>) -> Self

Build a map from pairs of (old, new).

pub fn get(&self, old: u16) -> Option<u16>

The new glyph ID for an old one.

pub fn pairs(&self) -> impl Iterator<Item = (u16, u16)> + '_

Every (old, new) pair, ascending by old ID.

pub fn len(&self) -> usize

How many glyphs survived.

pub fn is_empty(&self) -> bool

Whether nothing survived.
