A laid out glyph

Fields

start: usize

Start index of cluster in original line

end: usize

End index of cluster in original line

x: f32

X offset of hitbox

w: f32

width of hitbox

level: Level

Unicode BiDi embedding level, character is left-to-right if level is divisible by 2

cache_key: CacheKey

Cache key, see CacheKey

x_offset: f32

X offset in line

If you are dealing with physical coordinates, you will want to use Self::x_int together with CacheKey::x_bin instead. This will ensure the best alignment of the rasterized glyphs with the pixel grid.

This offset is useful when you are dealing with logical units and you do not care or cannot guarantee pixel grid alignment. For instance, when you want to use the glyphs for vectorial text, apply linear transformations to the layout, etc.

y_offset: f32

Y offset in line

If you are dealing with physical coordinates, you will want to use Self::y_int together with CacheKey::y_bin instead. This will ensure the best alignment of the rasterized glyphs with the pixel grid.

This offset is useful when you are dealing with logical units and you do not care or cannot guarantee pixel grid alignment. For instance, when you want to use the glyphs for vectorial text, apply linear transformations to the layout, etc.

x_int: i32

Integer component of X offset in line

y_int: i32

Integer component of Y offset in line

color_opt: Option<Color>

Optional color override

metadata: usize

Metadata from Attrs
