Arguments for PDF417 bar code symbology
97
This example prints a PDF417 bar code with the following settings:
/QuietZone [int int] [150 150] Optional
Sets the quiet zone in 1/600 inch. The default value is [150
150].
/Error Percent integer 0 Optional
This designates error correction levels by percentage. Valid
percentage values range from 0% to 400%. Any value outside
this range causes a RANGECHECK error. A valid non-zero
value overrides /ErrorLevel. See “/ErrorLevel” on page 96. A
zero value causes the /ErrorLevel value to be used.
If a valid non-zero percentage is specified, then the error
correction level is computed by selecting one of the /ErrorLevel
values (0–8).The error correction level selected is the one that
best matches the number generated by multiplying the
specified percentage by the number of data code words in the
symbol.
Example:
If there are 20 data code words in the symbol, and
/ErrorPercent is specified at 100% (100), then the /ErrorLevel
selected is the one closest to 20, or /ErrorLevel 3 (16 error code
words).
For the same 20 data code words, and an /ErrorPercent of 35%
(35), /ErrorLevel 2 is selected, because it is closest to 20 x 0.35,
or 7.
