The Problem with the Cpen OCR Software is, that i cannot grab the real 
image form the pen. I can only get an somehow processed image from the 
Cpen software  that i copied to gimp.

I did also some scans with lines etc. and i hope i can figure it out.

I am quite sure that the firmware on the pen gives me only an (inverted) 
black/white image.

Thanks for your hints,
Stefan
