l PDF417 Properties group:
l Module Width: Specifies the width of the narrow bars. Changing this value to a
higher value will generally make the Barcode bigger.
l Row height: Defines the height of the bars for a single row, measured in pixels,
points or metric.
l Width to height ratio: Select the ratio of column width to row height.
l Mode: Use the drop-down to set the compaction mode.
l Binary: allows any byte value to be encoded.
l Text: allows all printable ASCII characters to be end coded (ASCIIvalues 32
to 126 and some additional control characters).
l Numeric: more efficient mode for encoding numeric data.
l Auto: Automatically detect the data content and encodes using the most
appropriate method. This is the default option.
l Error Correction Level: Enter the error correction level for the built-in error
correction method based on Reed-Solomon algorithms. The error correction level is
adjustable between level 0 (just error detection, without correction) and level 8
(maximum error correction). Recommended error correction levels are between
level 2 and 5, but the optimal value depends on the amount of data, printing quality
of the PDF417 symbol and decoding capabilities.
l Rows: A PDF417 bar code can have anywhere from 3 to 90 rows.
l Columns: The number of data columns can vary from 1 to 30.
l
Tilde processing
Check this option to process tilde (~) characters in the data as special characters. (See
the Java4less Barcodes Guide to learn what the tilde character can be used for.)
The tilde is expected to be followed by the 'd' character and 3 digits representing an
ASCII character: ~dNNN . For example, ~d013 represents a carriage return.
Note that with this option checked, any tilde that needs to be included in the output must
be escaped by adding another tilde: ~~.
l Text: Enter the text used to generate the Barcode.
