Looks strange for me. I formerly put the dicom-writing in a program
that was called with the data-matrix and a filename. I checked the
data-type and some other stuff and then called all the stuff to
finally write the dicom-file.
I changed my program into a function that is called with the two
parameters data and filename and returns just an integer 0. And now it
looks like it works. For me, it becomes not clear why it works now,
but it works.
