Hi Olivier.
For our label/report generation we do draw the barcodes rather than use a Form.
Actually we have a Canvas that adapts to generate PDF so it is all WYSIWYG.
Therefore no actual dependency in the PDF generation to any barcode objects.
Looking to support Arefact instead of the stuff we have. Not looked at the
details of Artefact yet though.
TTF in PDF is not so bad... a snippet of what's expected in the output:

(actually we now use MacRoman encoding as generally works better).
All the data there can be gatherted from the FreeType TTF font in Pharo. Just
needs to be present on the end-user's pc.
A typical PDF reader will do fallbacks as necessary if not present.
(not tackled fully embedded fonts yet).

Hi Gary,
yes, I'm interested by help and pointers about TTF. It's a planned evolution
of Artefact.
About barcodes generation, why don't use Artefact directly ? You can draw
barcodes with the PDFDraw elements (PDFLineElement, PDFRectElement, etc.) and
print the document on stickers.
In the future, it could be cool to have a Artefact-Elements-Barcodes package
:)
Best regards
Olivier

Well, hoping to work with Torsten on barcodes in general, given we have
support for canvas based drawing of a few formats here at Pinesoft.
Also, if Olivier would like some help with TTF in PDFs I can give some
pointers etc.

You should be able to create a form, paint it white, draw on it with a
barcode TTF font, export that form to JPEG, and then use that JPEG into
Artefact.
Not really straight-forward, but it should work.
*Note: I've found that writing JPEG's in Pharo, it assumes that the
background is BLACK if it isn't isn't specifically painted with something else
first. Unlike PNG and GIF, which assume WHITE.

Hi Torsten,
Artefact don't support TTF fonts for the moment but it's planned in
futures versions.
Best regards

You just need a TTF font. Does Artefact support TTF? hpdf does.

Do we have some barcode stuff available for Pharo?
Something "Form" based that can be used with Artefact?
Thx
