Abstract

XBlend has two important structures: RGB<T> & RGBA<T>
where T can be f32 or u8 It's convenient to convert from each other and build a new color

Some examples

Create a RGB/RGBA color

extern crate xblend; use xblend::*; let color1 = rgba!(1.0,1.0,0.0,1.0); let color2 = rgba!(255,255,0,255); let color3 = rgba!(0xFFFF00FF);

Calculate the sum of two color

```

extern crate xblend;

use xblend::*;

let color2 = rgba!(255,255,0,255);

let color3 = rgba!(0xFFFF00FF);

// it's safe to overflow // the alpha component will NOT be evaluated assert_eq!(color2 + color3, rgba!(254,254,0,255)); ```

Blend two color

```

extern crate xblend;

use xblend::*;

use xblend::blend::SrcATop; let color1 = rgba!(128,133,0,128).tof32(); let color2 = rgba!(0.4,0.2,0.1,0.5); // Only RGBA can blended with srcout. // SrcOut Blending Mode asserteq!(color1.srcatop(color2).to_u8(), rgba!(114,91,12,127)); ```
