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.

NAME

       gifbg - A program to generate a single-color test pattern GIF with gradually changing intensity in any of the basic 8 directions.

USAGE

       gifbg [-q] [-d Dir] [-l #Lvls] [-c R G B] [-m MinI] [-M MaxI] [-s W H] [-h]

       The gifbg program reads no input, and will dump the created GIF file to stdout.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

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

       [-d Dir]

	       Select direction the intensity of the background should increase.  Direction can be one of the 8 principal directions:

	      T - for Top	  "TR" - for Top Right "R" - for Right		"BR" - for Bottom Right "B" - for Bottom	 "BL" - for Bottom
	      Left "L" - for left      "TL" - for Top Left

	      The compass directions may be use as synonyms for the above directions, so for example "NE" is equal to "TR".

	      Direction is case insensitive. The default direction is Top (North).

       [-l #Lvls]

	       Number of levels the color will be scaled to. Default is 16.

       [-c R G B]

	       What to use as the primary background color to scale.  This color is scaled between the minimum intensity (MinI) and maximum inten-
	      sity  (MaxI) from one end of the screen to the other as defined by Dir.  See below (-m & -M) for MinI & MaxI. Default is Blue (0, 0,
	      255).

       [-m MinI]

	       Minimum intensity (in percent) to scale color.  Default 10%

       [-M MaxI]

	       Maximum intensity (in percent) to scale color.  Default 100%

       [-s W H]

	       Size of image to create.  Default 640 by 350.

       [-h]

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

NOTES

       If MinI == MaxI = 100 (%) and #Lvls == 2 then boolean mask image of specified size will be created - all foreground.  This can be used as a
       square mask for the <a href="gifcomb.html">
