[gdal-dev] Bug in SetGCPs method of GDALDataset class??

[Chaitanya kumar CH]

Giuseppe,

Sorry for the confusion but the Python interface doesn't need the first
argument, the number of GCPs.
Examples:
http://trac.osgeo.org/gdal/browser/trunk/autotest/gcore/tiff_write.py#L236
http://trac.osgeo.org/gdal/browser/trunk/autotest/warp/warp.py#L695
