Sorry for the unclear issue. The example in doc works but creates only the IDF but there is no information about how to write the actual stripes / scanlines and couldnt' find any api in the library for doing so,

Aah the API is then a bit unclear there. The example not only writes the IFD but also one strip (containing 4 bytes of 0).
Things that are wrapped in IfdValue::Offsets are written by the DngWriter as well.
