pub enum ShadeCommand {
    Boundary {
        x: isize,
        y: isize,
        coverage: f32,

}

A command to shade a pixel.

Variants

Boundary

A command to shade a pixel at the boundary of path's raster area. Coverage indicates what percentage of the pixel is covered by the raster area. This usually maps to the alpha channel.

Fields of Boundary

x: isizey: isizecoverage: f32

Span

A command to shade a span of the framebuffer. Spans are completely covered in the raster area, so the alpha channel value for spans is usually 1.0.

Fields of Span

x: Range<isize>y: isize
