meanwhile you can use gdaltools in batch mode and with warp or translate set "-dstnodata 0" or "-a_nodata 0". By the way, do you have any performance issue with rotated images? see https://trac.osgeo.org/qgis/ticket/3794 cheers -- Giovanni -- _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
