[gdal-dev] ArcSDE -> GeoTiff: Bit size calculation failed...

[Wouter Schaubroeck]

Howard,

Thanks for the information. As soon as I have a ArcMAP installation,
I'll check this (should be a matter of days).

I believe it has to do with the fact that the raster layer you're reading from has a bitmask (bitmap) on it, and the SDE driver doesn't handle them.  The code probably needs to be updated to either disregard the mask, or handle it as a GDAL MaskBand.
