Hi, I have an issue with gdal_calc.py and nodata values.
My input data contains a lot of white pixels. After running gdal_calc.py with the following parameters
gdal_calc.py -A test.tif --outfile=testcalc.tif --calc="(A==249)*255+(A<>249)*A"
it turns out that all pixel values with 255 are now nodata values ;-( Is there an option so that my 255 values are not turned into nodata? I tested with the --NoDataValue option (e.g. 99 - which I don't use in the image), but it seems to be ignored. For me it is important that black and white pixels are preserved.
Thanks for any hints, Andreas _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
