NAME

       exrtools - a collection of utilities for manipulating OpenEXR images

DESCRIPTION

       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  some-
       one  may  find them useful.  Each application is small and reasonably self-contained such that the source code may be of most value to oth-
       ers.

       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.
