Enum raqote::Source

pub enum Source<'a> {
    Solid(SolidSource),
    Image(Image<'a>, ExtendMode, FilterMode, Transform),
    RadialGradient(Gradient, Spread, Transform),
    TwoCircleRadialGradient(Gradient, Spread, Point, f32, Point, f32, Transform),
    LinearGradient(Gradient, Spread, Transform),
}

LinearGradients have an implicit start point at 0,0 and an end point at 256,0. The transform parameter can be used to adjust them to the desired location. RadialGradients have an implict center at 0,0 and a radius of 128.

These locations are an artifact of the blitter implementation and will probably change in the future to become more ergonomic.

Methods

impl<'a> Source<'a>

pub fn new_linear_gradient(
    gradient: Gradient,
    start: Point,
    end: Point,
    spread: Spread
) -> Source<'a>

Creates a new linear gradient source where the start point corresponds to the gradient stop at position = 0 and the end point corresponds to the graident stop at position = 1.

pub fn new_radial_gradient(
    gradient: Gradient,
    center: Point,
    radius: f32,
    spread: Spread
) -> Source<'a>

Creates a new radial gradient that is centered at the given point and has the given radius.

pub fn new_two_circle_radial_gradient(
    gradient: Gradient,
    center1: Point,
    radius1: f32,
    center2: Point,
    radius2: f32,
    spread: Spread
) -> Source<'a>

Creates a new radial gradient that is centered at the given point and has the given radius.
