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  dy-
       namic-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.
