Struct beryllium::Color

#[repr(C)]
pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
}

An abstract RGBA color value.

• Each channel ranges from 0 (none) to 255 (maximum).
• Alpha channel is "opacity", so 255 is opaque.

A color value's exact representation within an image depends on the PixelFormat of the image. You can use the "get" and "map" methods of a PixelFormat to convert between raw pixel data and a Color value. Note that any PixelFormat that's less than 32 bits per pixel will lose information when you go from Color to raw pixel value, so the conversion isn't always reversible.

Fields

Red

g: u8

Green

b: u8

a: u8
