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.
