How to create a QR code in memory?

[fredywenger]

We have a (vb.net) application that creates invoices as .rtf files.
At runtime, a template (.rtf invoice with included images like logo and various variables) is loaded and the various variables (in the .rtf template) are replaced with data from a SQL server.
We now have to add a QR code to the invoice, that also has to be generated dynamically.

The idea is, to create the QR-code in memory (without save it as image) and then change a variable (placeholder) in the .rtf template thru the generated QR code (like the other variables).
So... how to do this with VPE?

Thanks for a feedback

I think there is no other way, but to export the QRCode as an image.

To increase performance, you can export the QRCode to a VPE memory stream, see PictureExportStream().
