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.
