Enum WidthSource

Source

pub enum WidthSource {
    Metric,
    Estimate,
}

Expand description

Whether a text span’s width was computed from real font metrics or estimated.

Variants§

§

Metric

Width derived from the font’s actual glyph advance data (/Widths, hmtx, CFF).

§

Estimate

Width estimated at APPROX_CHAR_WIDTH × font_size — no glyph metric available.
