Struct immi::GlyphInfos

pub struct GlyphInfos {
    pub width: f32,
    pub height: f32,
    pub x_offset: f32,
    pub y_offset: f32,
    pub x_advance: f32,
}

Information about a single glyph.

All the values of this struct must be relative to the size of an EM, so that the library can adjust the values to any size.

Fields

width: f32

Width of the glyph in pixels, divided by the number of pixels of an EM.

height: f32

Height of the glyph in pixels, divided by the number of pixels of an EM.

By definition, this value is supposed to be always 1.0 for the glyph 'M'. In practice this is not always exactly true.

x_offset: f32

Number of pixels from the end of the previous glyph to the start of this one, divided by the number of pixels of an EM.

y_offset: f32

Number of pixels from the base of the line to the top of this one, divided by the number of pixels of an EM.

For glyphs that don't go under the line (like 'm' or 'u' for example), this is equal to the height of the glyph. For glyphs that go under the line (like 'p' or 'g'), this is equal to the height of the glyph minus the portion that goes under the line.

x_advance: f32

Number of pixels from the end of the previous glyph to the end of this one, divided by the number of pixels of an EM.

Should always be superior to width + x_offset.
