exrtools(1) a collection of utilities for manipulating OpenEXR images


exrtools is a set of simple command-line utilities for dealing 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, and it is released in the hopes that someone may find them useful. Each application is small and reasonably self-contained such that the source code may be of most value to others.

The biggest assumption in most of this code is that the EXR files and PNG files all use sRGB primaries and gamma function. Fixing this is not very difficult, and the code to fix allows for some interesting possibilities. That said, I do not have time right now, so this will have to wait.
