DataMatrix Barcode

[EDV Gradl]

First of all, congratulations to you implementation of the 2D DataMatrix Barcode. This was the one feature I was missing. Also makes you product even cheaper since most Add-On Barcodes cost at least $300 (with almost no limit).
Once again: Nice work.

Now I am just having trouble with the properties of the datamatrix code.

Why does encoding change the barcode? Shoudl I use Text or ASCII or something else?
What is Matrix size? Some value only prodduce Not valid data, so it is best to keep Automatic, or is there a reason to use different settings?
Module seem to be the size (Yes, I figured that out myself!).
And I have no idea what UseRectangularSymbols does.

Thanks for the help and this cool new feature!
