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
  • Colors other than gray, rgb and rgba will be converted to rgb before writing
• 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: - TIFF - JPEG/JFIF - OpenEXR - PNG - HDR/RGBE - ICO - BMP - Targa - JPEG-2000 - RMan Zfile - FITS - DDS - Softimage PIC - PNM - DPX - Cineon - IFF - Field3D - Ptex - Photoshop PSD - Wavefront RLA - SGI - WebP - GIF - A variety of RAW digital camera formats

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.
