grapho-color

This is the color library used by the grapho-set of crates.

There is also:

• grapho-bitplane: describes pixel-buffers and allows converting color and interleave types
• grapho-2d: describes all kinds of 2D vector graphics and math (like polygon clipping)
• grapho-rasterize-2d: 2D rasterizer for the vectors described in grapho-2d
• grapho-filters: pixel based effects and filters for pixel buffers
• grapho-cv: computer vision library for grapho stack
• grapho-3d: 3D vector math

What does it do

grapho-color describes the color primitives that are used for computer graphics. It contains color conversion functionality and will get SIMD acceleration in the future to be the most effective color-library.

Currently the following color types are implemented:

• Normalized Grayscale (component values from 0.0 - 1.0)
• Normalized RGB (component values from 0.0 - 1.0)
• Normalized RGBA (component values from 0.0 - 1.0)
• Digital Grayscale (1 byte)
• Digital RGB (1 byte per channel)
• Digital RGBA (1 byte per channel)
• Normalized YCbCr (component values: Y -> 0.0 - 1.0, Cb/Cr -> -0.5 - 0.5)
• Digital YCbCr (1 byte per channel)
• CIE Lab (float components)
• CIE XYZ (float components)

Conversion from all color types into all others is implemented by implementing the From-trait.

Additionally there are *Convertible-traits for all color types which additionally implement functionality to convert iterators or Vec-Arrays. These will be implemented with SIMD in the future to provide the best performance possible.

To make integration of the color types easy with existing software there are From-traits for importing a color from Vec<u8> and u32 types.

TODO

• HSLColor
• HSVColor
• YCgCoColor
• SIMD Optimization for *Convertible-traits
