Struct ShapedGlyph

pub struct ShapedGlyph {
    pub glyph_id: u16,
    pub cluster: u32,
    pub x_advance: i32,
    pub y_advance: i32,
    pub x_offset: i32,
    pub y_offset: i32,
}

Expand description

A single glyph produced by OpenType shaping.

Fields§

§glyph_id: u16

Real glyph ID from GSUB (not a Unicode codepoint).

§cluster: u32

Index of the first character in the input text that maps to this glyph. Multiple chars may map to one glyph (ligatures), or one char may produce multiple glyphs (decomposition).

§x_advance: i32

Horizontal advance in font units.

§y_advance: i32

Vertical advance in font units (usually 0 for horizontal text).

§x_offset: i32

Horizontal offset from GPOS (kerning, mark positioning).

§y_offset: i32

Vertical offset from GPOS.
