  • Available for Win, Mac, Linux, FreeBSD and NetBSD
  • Supports a wide range of images and SVG
  • Caches images for faster reloading
  • Can display unassociated channels correctly (If your image uses alpha and color channels to encode data in a special way)
  • Lets you pick pixels, display location and color values
  • Offers basic nondestructive editing: Crop, resize, paint, contrast, HSV, rotate, blur, noise, ...
  • SIMD-accelerated image editing
