Struct Hdr

pub struct Hdr {
    pub flags: u16,
    pub upem: i32,
    pub asc: i32,
    pub desc: i32,
    pub gap: i32,

}

Expand description

the SGF1-compatible header every font kind has (font_data): what gc_scale and the text metrics read. i16 fields sign-extended, upem / nglyphs zero-extended.
