> Is there a simple way to find one or several pixel value none of the bands use ? Hi, Another GDAL users just some time ago told about a workaround for a little bit similar use case. The idea is to use first gdal_calc.py and update all (0,0,0) pixels into (1,1,1). Because of this little trick it is guaranteed that after runninig a process that generates (0,0,0) as nodata pixels, all that is (0,0,0) in the image comes from this process. For the users the (1,1,1) pixels of real data look just as black as they used to. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
