Hello Tilman,
thank you, indeed using the font you suggested works without problems.
Great !
For the sake of curiosity i compared the encoded strings for the same code
with my original font and with the working one:
not working: _8*L0G0L4G1G7L2**R0R6R0R4R0R6*
working: 8AKELRC*agaeag+
both render (using openoffice the first and pdfbox the second) to the same
barcode (i checked that both are also readable by my phone's barcode
scanner)
and actually the one not working has an encoded string way longer, maybe
that the incorrect font works only with ligatures?
Maybe. There was a GSUB table. I guess we'll never know. What counts is
that you got your application working.

Anyway my problem is solved.
Thank you very much,
Alberto.

Hello,
The POST table of the font is incorrect. You can open the font with DTL
OTMaster 3.7 light (a very nice software), go to "post names". You'll
see (at the bottom) the name "0" with the glyph index 302. However there
is no glyph at 302 in the glyf table. That index doesn't exist.
In the cmap tables the "0" points to index 44. That one is empty. The
"0" glyph would be at index 1 or 11.
I don't know how openoffice did it, I don't have openoffice/libreoffice,
and I didn't try on MS Office (for security reasons).
There is a different EAN13 font at
https://grandzebu.net/informatique/codbar-en/ean13.htm
but that one uses a different way to encode what you want, i.e. "0" is
"K" or "A" or "a". The website has a table on how to use this.

Hello, thanks.
The repro with the used font is available here:

two images of the result with pdfbox and openoffice are here:

Betreff: Problem rendering barcode font
Datum: 27.03.2019, 6:56 Uhr
An: [email protected]
Hi Community,
i'm using pdfbox to create a pdf-document from scratch and everything
works
well but the creation of a barcode using a barcode font.
Essentially we have a font for the ean13 barcode in ttf format and it
seems to work; when i install it on my mac and use it with openoffice
the
barcode is rendered correctly.
But if i use the same ttf font with pdfbox i get a wrong result (only
part
of the barcode seems drawn).
I'm far from being an expert of fonts and formats but i tried to analyze
the font and the problem but i found no way.
Can you suggest something to look?
If useful i can provide the font and a simple reproducer too of course.
Thank you very much,
Alberto.
