|pixfade [-f fraction] [-m max] [-p percentage] [infile.pix] > outfile.pix|
pixfade darkens a color pix file by fading the entire image a fractional amount or by using a pixel value as a maximum level.
The -f option specifies a nonnegative fractional multiplier which is used to scale the red, green, and blue values of each pixel. In a similar way, the -p option is used to specify the multiplier as a nonnegative percentage.
An alternative way to darken the image is to specify a ceiling pixel level (0 - 255) with the -m option. The pixel plotted is the minimum of the ceiling value and the red, green, and blue levels of the pixel.
