For 9 ≤n1n2 ≤400, the ECC level is assumed as a percentage of
the codewords in the bar code.
Select aspect ratio PDF417 bar code
EIA-232 Syntax:
GSSr;c or X'1D;53;r;c'
where:
rThe height dimension for the ratio; 1 ≤r≤9.
cThe width dimension for the ratio; 1 ≤c≤9.
Default:
r=1,c=2
Remarks:
This is not an exact ratio. The image will get as close as possible to the
ratio. However, the maximum width of an image is 12 columns and the
maximum height is 90 rows.
Enable PDF417 truncation
EIA-232 Syntax:
GSTnor X'1D;54;n'
where:
n Whether to enable truncation
0Disable truncation.
1Enable truncation.
Default:
n=0
Remarks:
Truncated PDF generates a symbol with the right row indicator and stop
pattern replaced by a single width bar. There is a slight degradation in
decode performance if truncation is enabled, which allows more data to fit
in the image width.
