Why does the PBM image have this text in it:

if it came from Windows?  Also why does the filename have "crop" in it?
Did you do some manipulation of the output file from the Windows
application?
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

I ask because it may be the case that the C-Pen puts out a format very
close to the default format the Windows app software would like to save
things in.  Comparing that default save format to the data in the URBs
may provide some insight.


Also a solid field isn't very helpful for making deductions about the
image data format.  Try a series of images: vertical line, horizontal
line, diagonal line, ellipse, rectangle, triangle, and square grid.
Then comparison of those source images vs the data bytes might give you
more insight into the format.


Godd Luck,
Andy

I hope someone can help me to :-)
