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  speci‐
       fied, and writes out a portable anymap.

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

       All flags can be abbreviated to their shortest unique prefix.
