.SH NAME
exrblur \- perform a gaussian blur on an OpenEXR image

.SH SYNOPSIS

.B exrblur
input.exr output.exr kernelsize

.SH 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.
