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

SYNOPSIS
       pnmflip  [-leftright|-lr]  [-topbottom|-tb]  [-transpose|-xy] [-rotate90|-r90|-ccw ] [-ro-
       tate270|-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 con-
       catenations  are available: -rotate90 or -ccw is equivalent to -transpose -topbottom; -ro-
       tate270 or -cw is equivalent to -transpose -leftright; and  -rotate180  is  equivalent  to
       -leftright -topbottom.

       All flags can be abbreviated to their shortest unique prefix.
