exrtools

'exrtools' is a set of simple utilities for manipulating with high dynamic range images in OpenEXR format, a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. The package currently includes the following tools: exrblur, exrchr, exricamtm, exrnlm, exrnormalize, exrpptm, exrstats, exrtopng, jpegtoexr, pngtoexr, ppmtoexr

'exrtools' was developed to help experiment with batch processing of HDR images for tone mapping. Each application is small and reasonably self-contained so that the source code may be of most value to others. It currently only works with RGBA OpenEXR files, and the code assumes 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.
