exrtools

Utilities for manipulating with HDR images in OpenEXR format

exrtools is a set of simple command-line utilities for manipulating with high dynamic range images in OpenEXR format. OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. exrtools was developed to help experiment with batch processing of HDR images for tone mapping. Each application is small and reasonably self-contained such that the source code may be of most value to others. exrtools currently only works with RGBA OpenEXR files. As well, the code assumes that the EXR files and PNG files all use sRGB primaries and gamma function.
