NAME

       gifcomb	-  A  program to combine 2 GIF images of exactly the same size into one.  The color maps are merged, but the result may not exceed
       256 colors.  A boolean mask GIF file can be used to set which pixel from two images to use at  each  location.	Otherwise  any	background
       color  from first image is converted to second image color at that point.  Only the first image of each file is combined; again, all files'
       first images must be of exactly the same size.

USAGE

       gifcomb [-q] [-m MaskGIFFile] [-h] gif-file...

       Two GIF files must be specified; a third mask GIF file is optional.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

	       Quiet mode.  Default off on MSDOS, on under UNIX.  Controls printout of running scan lines.  Use -q- to invert.

       [-m MaskGIFFile]

	       the MaskGIFfile can be regular GIF file whose first image has same dimensions as the combined images.  Any non-background color	in
	      it  will	select	Image  1 Pixel to output, otherwise Image2 pixel will be selected.  Usually this image will be boolean (two colors
	      only) but it does not have to be.

       [-h]

	       Print one line of command line help, similar to Usage above.
