Q: I am interested in enabling touch behaviour for the PDFViewWPF. I want to allow pinch zooming and panning with one finger. How do I accomplish this?
A: The PDFViewWPF allows touch interaction by simply setting the property IsManipulationEnabled to true;
There's also a property called DesiredLinearDeceleration which should control how fast the viewer decelerates when you fling to scroll. It works the same way as DesiredLinearDeceleration works on a ScrollViewer.
