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.
