Hello!
I'm having trouble with adding multiple TREs to a NITF file (using C++
API), the documentation mentions that the TRE creation options allows
for that but I can't figure out the syntax, how do I achieve something
like this: TRE=NAME1=VALUES1,NAME2=VALUES2 ? (I also tried to use TRE
creation option twice like so: -co TRE=NAME1=VALUES1 -co
TRE=NAME2=VALUES2, but the second TRE gets ignored)
You need to specify the TRE=NAME=VALUE several times
$ gdal_translate byte.tif test.ntf -co TRE=NAME1=VALUES1 -co
TRE=NAME2=VALUES2
$ gdalinfo test.ntf
[...]
Metadata (TRE):
NAME1=VALUES1
NAME2=VALUES2
Using the C++ API, this would be something like:
char** options = NULL;
options = CSLAddString(options, "TRE=NAME1=VALUES1"); // Do not use
CSLSetNameValue() otherwise the second TRE would override the first one
options = CSLAddString(options, "TRE=NAME2=VALUES2");
GDALCreateCopy(hDrv, "out.ntf", src_ds, false, options, nullptr, nullptr);
