       -S<sigma>
              sample distance (default 1.0)

       -b     adjust brightness after blurring

       -d<drmdev>
              use drmdev (/dev/dri/card0 e.g) to render

       -l<percent>
              multiple current lightness by percent [0.0-1.0]

       -s<percent>
              multiple current saturation by percent [0.0-1.0]

       -p<renderingpasses>
              iterate passes of rendering, ranging [1-INF]
