`glyph_index_metrics`

fn def glyph_index_metrics(mut face: TTFFace, glyph_index: Int) -> GlyphMetrics

One glyph’s advance/bearing/size, in pixels, addressed by glyph index rather than codepoint – what a glyph GSUB substitution produced has, since a ligature stands for several characters and none of their codepoints names it.

Args:

face (TTFFace): Face to measure against, with a pixel size already set.
glyph_index (Int): Glyph to measure.

Returns:

GlyphMetrics: The glyph’s advance/bearing/width/height at that size.

Raises:

face_line_metrics glyph_index_path
