Hello, I am creating image pyramid from a bunch of color GeoTIFF files using "gdal_retile" tool. I have managed to generate pyramid but unfortunately there is a problem - my GeoTIFFs maps overlap and have white margins around and I am unable to force GDAL to treat white color as transparent to avoid covering maps by these margins. I have tried all ideas I could imagine but to no avail. So my question is: how to tweak "gdal_retile" to get white color treated as transparent during merging? I am using GDAL 1.6 on Windows. Any help will be very, very appreciated - thank you.
