You need to use Rast_set_window() (or Rast_set_input_window() and/or Rast_set_ouput_window()) to change the window(s) used by the raster library. libgis functions (e.g. G_set_window()) can't do this because libgis is at a lower level than libraster. > Creating a new struct and asking for the current region provide me the > expected result. Bear in mind that this won't affect the raster I/O functions. The raster windows are initialised from the libgis window at startup, but won't change thereafter unless changed via the libraster functions. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
