RAW data processing

I wonder whether there is a way using LibRAW to process the RAW data (I think I read thru the manual how to do that) and to store that back in the RAW file (a NEF, for instance). To simplify, is it possible with LibRAW to *modify* a RAW file, instead than unpacking it for storage in a different format.

All the best for 2013, still 2 hours to go in Italy :)

The only common way to write

The only common way to write RAW files is to write DNG format ones. Adobe DNG SDK can be used for this task.

Is the content of the DNG

Is the content of the DNG payload a 16bit/sample stream? Or the unpacked data must be packed somehow after the processing?

Yes, you may simple pack

Yes, you may simple pack linear 16-bit data (bayer pattern or after demosaic) into DNG
