[Gdal-dev] Inserting RPC data into an image?

[Sarah Mulholland]

I have a NITF image and RPC data in an external 
file.  I'd like to embed the RPC data in the NITF 
file.  I see there's a GDALExtractRPCInfo function 
in gdal.  Would it be straightforward to create a 
similar GDALInsertRPCInfo function?

Here's what I want to do:
	- read the image (or the header),
	- fill a GDALRPCInfo object with the right values,
	- insert the RPC object into the image (gdal data 
set),
	- write it out with a new name.

Is this straightforward to do?

Thank in advance.
