Struct SubsetFont

Source

pub struct SubsetFont {
    pub bytes: Vec<u8>,
    pub glyph_mapping: BTreeMap<u16, (u16, char)>,
}

Expand description

Result of font subsetting operation.

Contains the subsetted font bytes and a mapping from original glyph IDs to new glyph IDs in the subset.

Fields§

§bytes: Vec<u8>

The subsetted font file bytes (smaller than original).

§glyph_mapping: BTreeMap<u16, (u16, char)>

Mapping: original glyph ID -> (new subset glyph ID, source character).

Implementations§

Source §

impl SubsetFont

Source

pub fn subset_text(&self, text: &str) -> String

Return the changed text so that when rendering with the subset font (instead of the original) the renderer will end up at the same glyph IDs as if we used the original text on the original font
