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
