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:

  • 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.
