Error Correction Level
Use the drop-down to select the built-in error correction method based on Reed-Solomon
algorithms. The error correction level is adjustable between level 0 (just error detection) 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 of the scanner.
Nr. of Columns
The number of data columns can vary from 3 to 30.
Nr. of Rows
A PDF417 bar code can have anywhere from 3 to 90 rows.
Bar height
Defines the height of the bars for a single row measured in pixels drawn.
Compact
Check this option to use Compact PDF417 instead of the PDF417 barcode. This shortened
form of the PDF417 barcode is useful where the space for the symbol is restricted.
Scale
Defines if and how the rendered barcode is scaled in relation to the parent element:
l None: The barcode is rendered based on the module width.
l Fit to box: The barcode is stretched to fit the parent box in both width and height.
l Proportionally: The barcode is stretched up to where it fits either the width or height of
the parent box, whichever requires the less stretching.
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.)
Note that with this option checked, any tilde that needs to be included in the output must be
escaped by adding another tilde: ~~.
