Crate rgb [−] [src]

Basic struct for RGB and RGBA pixels. Packed, with red first, alpha last.

This crate is intended to be the lowest common denominator for sharing RGB/RGBA bitmaps between other crates.

The crate includes convenience functions for converting between the struct and bytes, and overloaded operators that work on all channels at once.

This crate intentionally doesn't implement color management and other colorspaces.

Structs

RGB	This is it. The component type can be `u8` (aliased as `RGB8`), `u16` (aliased as `RGB16`), or any other type (but simple copyable types are recommended.)
RGBA	This is it. The component type can be `u8` (aliased as `RGBA8`), `u16` (aliased as `RGBA16`), or any other type (but simple copyable types are recommended.)

ByteSlice	Cast array of structs into array of raw bytes (so that `[0]` is R, `[1]` is G, `[2]` is B, etc.)
ComponentBytes	Casting the struct to slices/bytes of its components
ComponentMap	Applying operation to every component

RGB8	8-bit RGB. The colorspace is techincally undefined, but generally sRGB is assumed.
RGB16	16-bit RGB in machine's native endian. Be careful to perform byte-swapping when reading from files.
RGBA8	Alpha is last. The crate doesn't impose which value represents transparency, but usually it's 0 = transparent, 255 = opaque.
RGBA16	16-bit RGB in machine's native endian. Alpha is last.
