Expand description

A positioned scaled glyph.

Fields§

§key: GlyphRasterConfig

Hashable key that can be used to uniquely identify a rasterized glyph.

§font_index: usize

The index of the font used to generate this glyph position.

§parent: char

The associated character that generated this glyph. A character may generate multiple glyphs.

§x: f32

The xmin of the glyph bounding box. This represents the left side of the glyph. Dimensions are in pixels, and are always whole numbers.

§y: f32

The ymin of the glyph bounding box. If your coordinate system is PositiveYUp, this represents the bottom side of the glyph. If your coordinate system is PositiveYDown, this represents the top side of the glyph. This is like this so that (y + height) always produces the other bound for the glyph.

§width: usize

The width of the glyph. Dimensions are in pixels.

§height: usize

The height of the glyph. Dimensions are in pixels.

§byte_offset: usize

The byte offset into the original string used in the append call which created this glyph.

§char_data: CharacterData

Additional metadata associated with the character used to generate this glyph.

§user_data: U

Custom user data associated with the text styled used to generate this glyph.
