I've just added byte-mode encoding to Data Matrix and made this the
default encoding method since it is generally more efficient than
ASCII-mode encoding. The remaining EDIFACT, C40, TEXT and X12 modes
will be added in about a week's time thanks mainly to a generous code
contribution by Jörg Walter - thanks Jörg!
If you prefer to use ASCII-mode encoding then this can be selected
using the "encoding=ascii" option, e.g.:
50 50 moveto (http://www.terryburton.co.uk/barcodewriter/)
(encoding=ascii) datamatrix
I've also disabled the ability to encode raw codewords when in
ASCII-mode under the premise that if you know what you are doing by
directly encoding codewords then you should really encode the entire
input yourself as a sequence of ^NNN codewords. For this you must now
use the synonymous "raw" or "encoding=raw" options.
Let me know if you encounter any problems with the default byte-mode
encoding scheme.
Have fun,
Terry
