FILTER to adjust the coarseness. Values are integers>0. The default=3. # # -s sigma ... SIGMA for unsharpening. Values are float>0. The default=2 # # -g gain ... GAIN for unsharpening. Values are float>=0. The default=4. # # -t thickness ... THICKNESS of edges. Values are integers>=0. The default=0 # means no edges. # # -l lothresh ... LOTHRESHOLD is the canny edge detection low threshold. Values are # integers>=0. The default=20. # # -l hithresh ... HITHRESHOLD is the canny edge detection high threshold. Values are # integers>=0. The default=40. # # -c colors ... COLORS is a list of colors for colorizing the result. Any space-separate # list of valid IM colors is allowed. (No spaces withing rgb color triples). The # default is no colorization. # # REQUIREMENTS: IM 6.8.9.9 due to the use of the Kuwahara filter. IM 6.8.9-0 to use # the Canny edge detection.
