In fact, the faster approach is to convert the PNG to a JPEG picture with Pharo
and to include it into a PDF Document with Artefact. It's easy to do but I
can't estimate the quality lost of the picture (I suppose that's is important
for the scanning of the QRCode with a phone).
pharoByExampleLogo := (ZnClient new
url: 'http://pharobyexample.org/pictures/pbe-title.jpg';
get).
aPage := PDFPage new.
aPage add: (PDFJpegElement from: 5 mm@0mm wh: 160mm@90mm fromStream:
pharoByExampleLogo readStream).
The best solution is to create a QRCodeComponent in Artefact and draw the
QRCode directly in the PDF document.
