Library for reading and writing images - command line tools

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 -- that is, a "client app"
   doesn't need to know the details about any particular image file formats.
   Specific formats are implemented by DLL/DSO plugins.

 * 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, WebP. More coming! The plugins are really
   good at understanding all the strange corners of the image formats, and
   are very careful about preserving image metadata (including Exif, GPS, and
   IPTC data).

 * An ImageCache class that transparently manages a cache so that it can access
   truly vast amounts of image data (thousands of image files totaling hundreds
   of GB) very efficiently using only a tiny amount (tens of megabytes at most)
   of runtime memory. Additionally, a TextureSystem class provides filtered
   MIP-map texture lookups, atop the nice caching behavior of ImageCache.

 * Several image tools based on these classes, including iinfo (print detailed
   info about images), iconvert (convert among formats, data types, or modify
   metadata), idiff (compare images),igrep (search images for matching
   metadata). Because these tools are based on ImageInput/ImageOutput, they
   work with any image formats for which ImageIO plugins are available.

 * A really nice image viewer, iv, also based on OpenImageIO classes (and so
   will work with any formats for which plugins are available).

 * Supported on Linux, OS X, and Windows.

 * All available under the BSD license, so you may modify it and use it in both
   open source or proprietary apps.

This package contains command line tools, including iv image viewer.
