image2 - image processing library

A Rust crate focused on generic image processing for a wide range of image formats and data types. 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, and a variety of RAW digital camera formats" but ImageMagick can also be used instead. This is not a pure Rust crate, if that's important to you then image is probably a better fit.

• 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)
