Module u32_ext

Module for code specific to u32 base images.

The channel order of the pixel value processing functions here is assumed to be AABBGGRR, which is what OpenGL uses. Note that other graphical systems might use 32 bit color but with the same channel order (notably, windows GDI), so for those situations you’d have to shuffle the channels or something.

In the future, I will attempt to make this able to unpack, use, and repack other color channel orderings.

Traits

Extra functionality that’s only available to images of u32 values.
