Struct PremultipliedRgbaColor

#[repr(C)]
pub struct PremultipliedRgbaColor {
    pub red: u8,
    pub green: u8,
    pub blue: u8,
    pub alpha: u8,
}

Available on crate feature software-renderer only.

A color whose component have been pre-multiplied by alpha

The renderer operates faster on pre-multiplied color since it caches the multiplication of its component

PremultipliedRgbaColor can be constructed from a Color with the From trait. This conversion will pre-multiply the color components

Fields

red: u8

green: u8

blue: u8

alpha: u8
