QRCODE with no text

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hallo,

I try to insert a qrcode into a pdf file.

With 10.13 I get a visible code, which is recognized by QR Droid and ZXING Decoder online, but both show no text.

code:
            ok = qp.DrawText(100, 50, "100/50");
            Console.WriteLine("draw text: {0}", ok);

            ok = qp.DrawQRCode(100, 100, 25, "hallo", 1, 0);
            Console.WriteLine("draw code: {0}", ok);

Any ideas?

Michi

	The following code works well in 10.13 and 1014 Beta 1. Can you try calling QP.NormalizePage(0); QP.AddStandardFont(4); before writing to the PDF file. I suspect this will fix all your problems. Andrew.
