pub fn build_lut_bytes(stops: &[ColorStop], space: GradientSpace) -> Vec<u8> ⓘExpand description
Build an RGBA8 LUT of LUT_SAMPLES equally spaced samples spanning
LUT_DOMAIN. The returned vector has LUT_SAMPLES * 4 bytes in
straight-alpha, row-major. The GPU shader expects this layout and
premultiplies at sample time.
