I have 1bit (b+w) input GeoTIFF files and want to change them to 8bit gray
value pixels where the white bits are set to transparent. I had a look at
the gdal_translate and GeoTIFF options but did not find a way to
accomplish this task. Maybe I have overlooked some parameters/switches?
If this can't be accomplished with gdal - can you recommend another tool,
preferably a commandline tool?
