PDF417 Settings
PDF417 is a two-dimensional, multi-row Barcode. It is used for encoding large amounts of data, with hundreds or even thousands of characters. It encodes alphabetic text, numbers, binary files and actual data bytes.
Use the following options to configure the output Barcode settings:
- PDF417 Properties group:
- Module Width: Specifies
the width of the narrow bars. Changing this value to
higher value will generally make the Barcode bigger.
- Row height: Defines the
height of the bars for a single row, measured in pixels, points or metric.
- Width to height ratio: Select the ratio of column width to row height.
- Mode: Use the drop-down
to set the compaction mode.
- Binary: allows any
byte value to be encoded.
- Text: allows all printable
ASCII characters to be end coded (ASCII values 32 to 126 and some additional
control characters).
- Numeric: more efficient
mode for encoding numeric data.
- Auto: Automatically
detect the data content and encodes using the most appropriate
method. This is the default option.
- 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.
- Rows: A PDF417 bar code
can have anywhere from 3 to 90 rows.
- Columns: The number of
data columns can vary from 1 to 30.
- Text: Enter the text used
to generate the Barcode.
Add button: Click to display
a list of variable data that can be added to the Barcode. This
includes metadata fields added in the Metadata
Options, as well as some information fields.
- Condition: Enter the condition
which determines whether or not the Barcode will be added to the document at print time. For details on how to create a conditional, see the How to Set Conditionals page.
Add button: Click to display
a list of metadata fields, information fields to add, or common
expressions to the condition.
