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.
