exrblur1
Perform a gaussian blur on an openexr image
Usage
exrblur input.exr
output.exr
kernelsize
Overview
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.
Releases
Unchanged in 6 releases since Debian 3.1 (Sarge).
