Hi (all),

I did what you suggest (METERS->DD), but it remains a blank image!!

If you want (need), I may send you (anyone of you) a shp file (20k not
compressed yet) to test it and figure why it won't work!! The demo works
fine, and since I already tried in my layers of POLYGONS to match the
LINE type (could be a mistake of conversion), but no luck!

thanks,
Pedro Salazar.
