Description
The way GeoRaster stores Bitmap Mask is similar in concept with GDAL Mask Band but not quite the same. The GeoRaster bitmap mask are stored as 1 bit per pixel and a GeoRaster could have one bitmap mask for all bands or one for each band.
The mapping between GeoRaster bitmap mask to GDAL mask band could be revised. But in the meantime there is a crash every time GDAL tries to read a GeoRaster with bitmap mask.
Warning 1: BLOB size (8192) is smaller than expected (196608) ! Warning 1: BLOB size (8192) is smaller than expected (196608) ! Warning 1: BLOB size (8192) is smaller than expected (196608) ! Warning 1: BLOB size (8192) is smaller than expected (196608) ! ...10...20...30...40...50...60...70...80...90...100 - done.
It seems like the driver is trying to read a Raster Band BLOB from a Bitmap Mask BLOB, since 8192 * 8 * 3 is equal 196608.
