       exrtools - 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.
