NAME
      pnmflip - perform one or more flip operations on a portable anymap

SYNOPSIS
      pnmflip [-leftright|-lr] [-topbottom|-tb] [-transpose|-xy] [-rotate90|-
      r90|-ccw ] [-rotate270|-r270|-cw ] [-rotate180|-r180] [pnmfile]

DESCRIPTION
      Reads a portable anymap as input.  Performs one or more flip operations,
      in the order specified, and writes out a portable anymap.

OPTIONS
      The flip operations available are: left for right (-leftright or -lr);
      top for bottom (-topbottom or -tb); and transposition (-transpose or -
      xy).  In addition, some canned concatenations are available:  -rotate90
      or -ccw is equivalent to -transpose -topbottom; -rotate270 or -cw is
      equivalent to -transpose -leftright; and -rotate180 is equivalent to -
      leftright -topbottom.

      All flags can be abbreviated to their shortest unique prefix.
