image2 - image processing library

A Rust crate focused on generic image processing for a wide range of image formats and data types.

Supported image data types: u8, i8, u16, i16, u32, i32, u64, i64, f16, f32, f64
Supported color types: gray, rgb, rgba, hsv, cmyk, xyz
Read and write images of any supported type/color
Easy to add new colors
Generic image processing across data types using Pixel
Composable operations using Filter (with async support)

OpenImageIO is used to read/write images and supports:

ImageMagick can also be used in place of OpenImageIO.

This is not a pure Rust crate, if that's important to you then image is probably a better fit.
