Use Scale, Rotate, Translate, Transform, then follow with
Inquire("apply transform").
Or if you want the net transformation matrix, Inquire("transformation
matrix"). After that, you are on your own! (:-)

Hi all,
I tried using the Scale, Rotate, and Translate modules to operate on
the
positions component, but they don't actually change the positions, only
the arrangement in the Image.
I want to apply a transformation matrix on a GeoTIFF file using the
Compute module, as in the following:
coords = Mark( field, "positions");
temp_coords = Compute( "$0 dot $1", coords, matrix );
field = Unmark(temp_coords, "positions");
So how do I build the transformation matrix?
TIA,
Fred Ramsing
