=head1 DESCRIPTION |
35
|
|
|
|
|
|
|
|
36
|
|
|
|
|
|
|
This class is used to generate data for Data Matrix barcodes. It is primarily |
37
|
|
|
|
|
|
|
useful as a data source for barcode modules that do rendering, |
38
|
|
|
|
|
|
|
such as L. You can easily make a version that |
39
|
|
|
|
|
|
|
renders an image, PDF, or anything else. |

46
|
|
|
|
|
|
|
can take any of the other L listed below. |

|

|
|
|
|
|
Generate barcode data representing the C<$text> string. This returns |
53
|
|
|
|
|
|
|
an array ref of rows in the data matrix, each containing array refs of |
54
|
|
|
|
|
|
|
cells within that row. The cells are true and false values |
55
|
|
|
|
|
|
|
that represent filled or empty squares. |
56
|
|
|
|
|
|
|
|
57
|
|
|
|
|
|
|
This can throw an exception if it's unable to generate the barcode data. |
