[gdal-dev] gdal create tif, errors with gdaladdo

[Stephen Woodbridge]

Hi,

I just created a bunch of tif files from a mrsid file and when I use 
gdaladdo file.tif 2 4 8 16 32 64 128 256

I get over a 1000 errors like:

ERROR 1: n-41-25_0-0.tif:DumpModeDecode: Not enough data for scanline 1536
ERROR 1: TIFFReadEncodedTile() failed.
ERROR 1: IReadBlock failed at X offset 12, Y offset 7
ERROR 1: GetBlockRef failed at X block offset 12, Y block offset 7
ERROR 1: n-41-25_0-0.tif:DumpModeDecode: Not enough data for scanline 1664
ERROR 1: TIFFReadEncodedTile() failed.
ERROR 1: IReadBlock failed at X offset 13, Y offset 7
ERROR 1: GetBlockRef failed at X block offset 13, Y block offset 7



Is this because of the number of overviews I requested? ot something 
else? Is it safe to ignore these?
