I am trying to create image overviews for a GTiff file using

ERROR 1: TIFFSetField:VISUAL.tif: Cannot modify tag "TileLength" while

ERROR 1: TIFFBuildOverviews:Can not write tiles to a stripped image
Here is my code:
int OverviewList[5] = { 2, 4, 8, 16, 32 };
CPLErr overview_err = outDS->BuildOverviews( "AVERAGE_MAGPHASE", 5,
OverviewList, 0, NULL, NULL, NULL );
I have used BuildOverviews before on HFA images and they are fine. Any
idea?
Ozy,
I'm surprised. I wonder if you might have opened your file in read-only
mode? Can you reproduce the problem with the gdaladdo commandline program?
Best regards,
