Expand description

An encoded gradient.

Fields§

§kind: EncodedKind

The underlying kind of gradient.

§transform: Affine

A transform that needs to be applied to the position of the first processed pixel.

§x_advance: Vec2

How much to advance into the x/y direction for one step in the x direction.

§y_advance: Vec2

How much to advance into the x/y direction for one step in the y direction.

§ranges: Vec<GradientRange>

The color ranges of the gradient.

§pad: bool

Whether the gradient should be padded.

§has_opacities: bool

Whether the gradient requires source_over compositing.

§u8_lut: OnceCell<GradientLut<u8>>§f32_lut: OnceCell<GradientLut<f32>>
