(nwl) Re: [gdal-dev] Saving data to the TEXT domain NITF

[Kurt Landrus]

What about TRE domain data, does the NITF driver support saving data  
to the TRE domain?
I've tried the following code to save tre data, but there is not TRE  
segment in the new file, and
the error code returned is 0.

        err = GDALSetMetadataItem(dataset, tre, treValue, "TRE");
        IFDBG printf( "  saved TRE %s= %s\n errcode=%i\n", tre,  
treValue, err);
