## 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.

-h

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