NAME

       gifrsize - A program to resize image size by an integer factor, deleting bits when scaling down and duplicating bits when scaling up.

USAGE

       gifrsize [-q] [-S X Y] [-s Scale] [-x XScale] [-y YScale] [-h] gif-file

       If no gif-file is given, GifRSize will try to read a GIF file from stdin.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

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

       [-S X Y]

	       specifies the exact screen dimension of the output GIF.

       [-s Scale]

	       Set scaling factor for both x & y direction to Scale.  Default is 0.5. Note this is a floating point number.

       [-x XScale]

	       Set scaling factor for x direction to Scale.  Default is 0.5.  Note: this is a floating point number.

       [-y YScale]

	       Set scaling factor for y direction to Scale. Default is 0.5.  Note: this is a floating point number.

       [-h]

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

NAME

       giftext - A program to dump (text only) general information about GIF file.

USAGE

       giftext [-q] [-c] [-e] [-z] [-p] [-r] [-h] gif-file

       If no gif-file is given, GifText will try to read a GIF file from stdin.

       As  giftext  can  generate  huge  amounts  of data, ^C will kill it, but 'q' will stop only the printing (of one of -e, -z, -p), while file
       integrity will still be checked.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

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

       [-c]

	       Dumps the color maps.

       [-e]

	       Dumps encoded bytes - the pixels after compressed using LZ algorithm and chained to form bytes.	This is the form the data is saved
	      in the GIF file.	Dumps in hex - 2 digit per byte.

       [-z]

	       Dumps the LZ codes of the image.  Dumps in hex - 3 digits per code (as we are limited to 12 bits).

       [-p]

	       Dumps the pixels of the image.  Dumps in hex - 2 digit per pixel (<=byte).

       [-r]

	       Dumps raw pixels as one byte per pixel.	This option inhibits all other options and only the pixels are dumped.	This option may be
	      used to convert GIF files into raw data.	Note: the color map can be extracted by gifclrmp utility.   If	more  than  one  image	is
	      included in the file, all images will be dumped in order.

       [-h]

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