An embedded bitmap glyph.

Fields

data: BitmapData<'a>

The underlying data of the bitmap glyph.

bearing_x: f32

Outer glyph bearings in the x direction, given in font units.

bearing_y: f32

Outer glyph bearings in the y direction, given in font units.

inner_bearing_x: f32

Inner glyph bearings in the x direction, given in pixels. This value should be scaled by ppem_* and be applied as an offset when placing the image within the bounds rectangle.

inner_bearing_y: f32

Inner glyph bearings in the y direction, given in pixels. This value should be scaled by ppem_* and be applied as an offset when placing the image within the bounds rectangle.

ppem_x: f32

The assumed pixels-per-em in the x direction.

ppem_y: f32

The assumed pixels-per-em in the y direction.

advance: Option<f32>

The horizontal advance width of the bitmap glyph in pixels, if given.

width: u32

The number of columns in the bitmap.

height: u32

The number of rows in the bitmap.

placement_origin: Origin

The placement origin of the bitmap.
