USAGE: sketchetch [-m mode] [-e etch] [-B brightness] [-S saturation] [-h hue]
[-c color] [-C coloramt] [-t type] [infile] [outfile]
-m ... mode ......... mode for processing; choices are: normal, grayscale, PURPOSE: To create an etch-like sketch from an image. DESCRIPTION: PIP creates an etch-like sketch from an image. There is an option for modes of normal, grayscale, colorized grayscale, shaded grayscale and three different composite types. ARGUMENTS: -m mode ... MODE for processing. The choices are: normal, grayscale, colorized (from grayscale), shaded (from grayscale) and composite. The default=normal. -e etch ... ETCH amount. Values are integers>0. The default=4. -B brightness ... BRIGHTNESS percent change of the image. Value are -100<=integer<=100. The default=0. -S saturation ... SATURATION percent change of the image. Value are -100<=integer<=100. The default=0. -H hue ... HUE angle change of the image in degrees. Value are -360<=integer<=360. The default=0. -c color ... COLOR is the colorizing color. Any valid opaque IM color is allowed. The default=sienna1. -C coloramt ... COLORAMT is the colorizing amount. Values are 0<=integers<=100. The default=50. -t type ... TYPE of composite (compose mode). The choices are: hardlight, overlay and softlight. The default=hardlight
