Date: Thu, 16 Jan 2003 13:48:31 +0200 From: "Mike Gorchak" added help and options -mono to force monochrome RGB2YUB conversion and -lum <percent> - luminance of image during conversion. Also rewritten code which moves overlay into window. Now it depends on window size. Also fully rewritten -scale option, image now scaling from 50% from center of screen until border of window is reached - it really tests scaler, old -scale test doesn't test downscale.
