Zooming PDFViewWPF by touch gestures

We've got an application which was running with PDFNet.dll in version 6.3.2. Zooming by touch gestures was working properly. Since we've updated PDFNet to Version 6.8.2 (and the newest PDFNetTools) it doesn't work anymore. Touch handling in general works without problems, but not zooming a pdf in or out.

I've found a possible solution in a google group which is mentioning to set

_PdfView.IsManipulationEnabled = true;

which is exactly what we've done before (6.3.2) and already doing with the newer version of PDFNet. Sadly this doesn't help.

Are there other hints or solutions to fix this problem?

The same applies to drawing annotations with an Microsoft Surface Pen, but I think both relate to the same problem.

I tested for this issue with version 6.3.2, 6.8.3 and 6.9.0. I was not able to find v6.8.2 in our regular stable releases.

Zooming gesture worked in all cases. Can you please try one of our sample projects to see if you can reproduce the issue? A good one for your case would be PDFViewWPFTest sample.

In any case, I would highly recommend you to upgrade to the latest SDK version from our website: https://www.pdftron.com/downloads/

Please let us know if this resolves your issue or if you have any questions.
