Allow for bar width reduction #541

Closed ro0NL closed 2 years ago

ro0NL commented 2 years ago

Hi,

See https://barcode-test.com/barcode-advice/bar-width-reduction/ for more information

See also https://sourceforge.net/p/tcpdf/discussion/435311/thread/e00f50f8/#756c, which ultimately led to this fix

I can confirm BWR on our side is also needed to account for "press gain compensation"

We are currenly applying this patch for 2-3 years in prod, and if it could be merged upstream, well, i'd be super happy :)

Thoughts?

Could you also add an example file in examples like https://github.com/tecnickcom/TCPDF/blob/main/examples/example_066.php ?

@williamdes i've updated existing example_027, which seemed best for general discoverability

.5 as an example value should give a good impression what this option does:
