It is expected and there is no support for opening a JPEG image in update mode. The JPEG format is essentially read-only or write-only. You cannot modify the imagery in place without regenerating a full file. You can use the CreateCopy() method of the JPEG driver for that. > > Thanks in advance, > Akhy Hückelheim > _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
