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.
