NAME

       exrblur - perform a gaussian blur on an OpenEXR image

SYNOPSIS

       exrblur input.exr output.exr kernelsize

DESCRIPTION

       Performs  a  gaussian blur on the input image.  This is useful for generating a whitepoint
       image for chromatic adaptation of locally adapting tone mapping algorithms.

       The kernel size for the blur is given as a fraction of the image width.  So, a  kernelsize
       of 0.25 will perform a blur with a kernel width 1/4 of the image width.
