[Gdal-dev] gdaladdo with .rrd ignoring compress overviews?

[Matt Wilkie]

Hi gdal, I'm on roll today! Here's another one: Why does gdalinfo report 
that overviews are compressed with RLC when I asked for LZW? Can only 
one --config option be used at a time? Or does .rrd not support choice 
of compression?

    gdaladdo --config use_rrd yes --config compress_overview lzw -r 
nearest 094M.tif 2 4 8 16 32
