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 gener‐
ating 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.
