Rgba8

Struct Rgba8 

Source
#[repr(C)]
pub struct Rgba8 { pub r: u8, pub g: u8, pub b: u8, pub a: u8, }
Expand description

Re-export every public type from the color crate, including all arithmetic helpers from color::convert.

Downstream modules within this crate can import everything they need with a single use crate::types::*. 8-bit RGBA, 4 bytes/pixel, wire layout [R, G, B, A].

This is the working format for transparency groups. The MODE constant is set to PixelMode::Xbgr8 as an intentional approximation: the rasterizer internally uses this struct for transparency groups and the mode field is only used for external dispatch (e.g. choosing a blitter). The actual byte layout is [R, G, B, A], not [X, B, G, R]; callers that perform memory-layout-sensitive operations must use the struct fields directly rather than relying on the MODE variant.

Fields§

§r: u8

Red channel, 0 = minimum, 255 = full intensity.

§g: u8

Green channel, 0 = minimum, 255 = full intensity.

§b: u8

Blue channel, 0 = minimum, 255 = full intensity.

§a: u8

Alpha channel, 0 = fully transparent, 255 = fully opaque.
