}

A solid color or gradient used to fill a region.

Gradients are normalized. A linear gradient is reduced to two points with its stops between them. Other gradients have their stops in the range 0 to 1, with their geometry adjusted to match.

Variants

Solid

A solid fill with the color at palette_index, multiplied by alpha.

Fields

palette_index: u16

alpha: f32

LinearGradient

A linear gradient from p0 to p1, reduced from the three points in the table.

With one stop, the fill is the solid color of that stop.

Fields

p0: Point<f32>

p1: Point<f32>

color_stops: &'a [ColorStop]

extend: Extend

RadialGradient

A radial gradient between two circles.

Normalizing the stops can produce a negative radius. In that case, the color line is truncated where the interpolated radius reaches zero.

Fields

c0: Point<f32>

r0: f32

c1: Point<f32>

r1: f32

color_stops: &'a [ColorStop]

extend: Extend

SweepGradient

A sweep gradient around c0, with angles in degrees clockwise.

This is the reverse of the direction in the table. Normalizing the stops can move the angles outside 0 to 360. Only that range is drawn.

Fields

c0: Point<f32>

start_angle: f32

end_angle: f32

color_stops: &'a [ColorStop]

extend: Extend
