DataMatrix is a 2-D matrix code designed to pack a lot of
information in a very small space. A Data Matrix symbol can store
between one and 500 characters. The symbol is also scalable between
a 1-mil square to a 14-inch square. That means that a Data Matrix
symbol has a maximum theoretical density of 500 million characters
to the inch! The practical density will, of course, be limited by
the resolution of the printing and reading technology used.
Use Caret (^)
The UseCaret propeties is set to true by default which is only apply
to Code128, UccEan128, Sscc18, Scc14, PDF417, MacroPDF417, QR Code,
and DataMatrix etc. where full ASCII is accepted as encoding. The 3
digits data following the caret will be treated as ASCII code, e.g.
^010 is \n; ^009 is a tab; ^065 is character 'A'.
DataMatrix Properties
Besides the properties to general barcode, the following properties
belongs to DataMatrix only:
DataMatrixBarSize gets or sets the narrow
bar size in inches for DataMatrix. Default is 0.02 inch.
DataMatrixEncodingMode gets or sets the
DataMatrix encoding mode. Default is Ascii encoding. Four type of
mode available:
(1) Ascii: it is used to encode data that mainly contains ASCII
characters (0-127).
(2) C40: it is used to encode data that mainly contains numeric and
upper case characters.
(3) Text: it is used to encode data that mainly contains numeric and
lower case characters.
(4) Base256: it is used to encode 8 bit values.
DataMatrixPreferredFormat gets or sets the
DataMatrix DataMatrixPreferredFormat. Default is Auto.
