This is a sub-module to PDF::Reuse. It creates barcode "images" to be used in
|
||
|
|
PDF documents. It uses GD::Barcode and its sub-modules: GD::Barcode::Code39,
|
||
|
|
COOP2of5, EAN13 and so on, to calculate the barcode pattern. For Code128 it uses
|
||
|
|
Barcode::Code128.
|
||
|
|
|
||
|
|
Normally the barcodes are displayed on a white background and with the
|
||
|
|
characters under the bars. You can rotate the "image", make it smaller or
|
||
|
|
bigger, prolong the bars and change the background. (But then, don't forget to
|
||
|
|
test that your barcode scanner still understands it.)
|
||
|
|
|
||
|
|
If you don't change the size of the "image", the bars are approximately 24
|
||
|
|
pixels high (the guard bars a few pixels longer) and the box/background is 38
|
||
|
|
pixels high and something like 20 pixels wider than the barcodes. The text
|
||
|
|
under the bars are 10 pixels high.
