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.
