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.
