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.
