[gradsusr] Is there a way to reverse the orientation of an image from the command line or within a script?

[Stephen McMillan]

Hi Bob,

Have you tried 'set yflip on|off'?  It's not the same result as rotating an
image, but rather reverses the order of the vertical axis.  As such, the
map also reverses (as in flipping a page over).
