Function shader

pub fn shader(
    shader: impl Into<RCHandle<SkShader>>,
    crop_rect: impl Into<CropRect>,
) -> Option<RCHandle<SkImageFilter>>

Create a filter that fills the output with the per-pixel evaluation of the Shader. The shader is defined in the image filter’s local coordinate system, so will automatically be affected by [Canvas'] transform.

Like image() and Picture(), this is a leaf filter that can be used to introduce inputs to a complex filter graph, but should generally be combined with a filter that as at least one null input to use the implicit source image.
