Barcode properties
This topic lists the properties of the Data Matrix barcode. For the properties of other barcode
types, see "Barcode type and properties" on page673.
Note
Tilde characters in the data are processed as special characters (see the Java4less
Barcodes Guide to learn what the tilde character can be used for).
Any tilde that needs to be included in the output must be escaped by adding another tilde
(either "~~", or "7E7E" if the Hex input option is enabled). This can be done with a
replace() call in the Barcode script, after expanding the script.
Hex Input
For optimized mailings, German Post requires the supplied data for the Data Matrix barcode to
be hexadecimal input.
Check this option if your input data is a hexadecimal code. The incoming data will be
interpreted as hexadecimal input and decoded to ASCII before passing the string to the
Barcode library.
Dots Per Pixels
Type the number of dots per pixel. To optimize barcode quality a Data Matrix symbol should not
be printed with dots smaller than 4 pixels.
Encoding
The data represented in the symbol can be compressed using of the following algorithms.
l ASCII is used to encode data that mainly contains ascii characters (0-127)
l C40 is used to encode data that mainly contains numbers and uppercase characters.
l Text is used to encode data that mainly contains numbers and lowercase
l Base256 is used to encode 8 bit values
l Auto Detect automatically detects the data content and encodes using the most
appropriate method.
l None does not use any encoding.
