for the record, you can create a "worldfile" for a PNG the same as for a plain TIFF image, and GDAL will pick it up. It needs to be named the same as the image but with a .pgw extension. http://gdal.org/frmt_various.html#PNG I'm not sure if anything other than GDAL-based things would respect that though, or if this trick helps for Sudeep's question or not. (GDAL's virtual-raster format is another wonderful cpu-saving device worth mentioning btw) http://www.gdal.org/gdal_vrttut.html Hamish _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
