[GRASS-user] Rotate a map display

[Vincent Bain]

Jérôme,

If you need to warp a map for a strict display purpose, IMHO it's not to
be performed from within grass given that this operation makes no sense
"geographically". Don't know what the context is, but if you just have
to rotate an image output of a map maybe you'd better look towards image
manipulation tools (e.g. imagemagick and the -rotate option, which can
easily be integrated in a script process).
Let us know a bit more about your needs !
