[Gdal-dev] tiff errors on gdaladdo

[Bart van den Eijnden]

Hi list,

we are trying to build overviews using gdaladdo but are running into errors:

0...10...20...30...40...50...Warning 1: 765/b765-1924.tif:PackBitsDecode:

Is this solveable? Or is it a problem of the source tiff files?

Best regards,
