NAME
       gifflip - flip a GIF around a specified axis or rotate it 90 degrees

SYNOPSIS
       gifflip [-v] [-r] [-l] [-x] [-y] [-h] [gif-file]

DESCRIPTION
       A program to flip (mirror) GIF file along X or Y axes, or rotate the
       GIF file 90 degrees to the left or to the right.

       If no GIF file is given, gifflip will try to read a GIF file from
       stdin.

OPTIONS
       -v
           Verbose mode. Enables printout of running scan lines.

       -r
           Rotate the GIF file to the right.

       -l
           Rotate the GIF file to the left.

       -x
           Mirror the GIF file along the X axis. Very useful if GIF file was
           created from another format in with the first line in at image
           bottom. Effectively exchanges first row with last.

       -y
           Mirror the GIF file along Y axis. Effectively exchanges first
           column with last.

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