//! # XBlend
//! xblend is a simple color library can calculate color blending.
//! ### homepage
//! [crates.io](https://crates.io/crates/xblend)
//! ### Documentation
//! [docs.rs](https://docs.rs/xblend/)
//! ### Source
//! [github](https://github.com/xstater/xblend)
//! ## Abstract
//! XBlend has two important structures: RGB&lt;T&gt; & RGBA&lt;T&gt; <br>
//! 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).to_f32();
//! let color2 = rgba!(0.4,0.2,0.1,0.5);
//! // Only RGBA<f32> can blended with src_out.
//! // SrcOut Blending Mode
//! assert_eq!(color1.src_atop(color2).to_u8(), rgba!(114,91,12,127));
//! ```
