OpenImageIO is a library for reading and writing images, and a bunch of related
classes, utilities, and applications. Main features include:
- Extremely simple but powerful ImageInput and ImageOutput APIs for reading and
writing 2D images that is format agnostic.
- Format plugins for TIFF, JPEG/JFIF, OpenEXR, PNG, HDR/RGBE, Targa, JPEG-2000,
DPX, Cineon, FITS, BMP, ICO, RMan Zfile, Softimage PIC, DDS, SGI,
PNM/PPM/PGM/PBM, Field3d.
- An ImageCache class that transparently manages a cache so that it can access
truly vast amounts of image data.
- A really nice image viewer, iv, also based on OpenImageIO classes (and so
will work with any formats for which plugins are available).
