I'm attempting to use CreateMaskBand() on a MrSID dataset with GDAL 1.8.0 and receiving the error that "CreateMaskBand() is not supported on this dataset." I presume this is because mask band support was implemented using the GDALDefaultOverviews manager, and since MrSID is a multi-resolution format, the overview manager is never initialized.
Is there a way to make mask bands work with MrSID datasets out of the box? Barring that, since the MrSID driver reimplements the overview-related virtual functions to bypass the default overview manager, would there be any harm in initializing the overview manager when a MrSIDDataset object is created? -b -- Brian Claywell bcclayw...@gmail.com _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
