Module luminance::pixel

Pixel formats types and function manipulation.

The Pixel trait is used to reify a pixel type at runtime via PixelFormat. It is made of several parts:

• Pixel::Encoding, an associated type, giving the type used to represent a single pixel.
• Pixel::RawEncoding, an associated typed that represents the encoding of underlying values in each channel of a single pixel.
• Pixel::SamplerType, the type of sampler that is needed to be used to access this pixel format on the GPU / in shaders.
• Pixel::pixel_format, a function returning the PixelFormat, reified version of the type at runtime.
