I’m working on graphs and in my project I would like to add multitouch capabilities, I used graphsharp and wpfextensions in my project.
However when I want to add zooming capabilities, normally in all sources it is shown as a matrix and etc.
I wonder is there any idea that I can use deltaManipulation.Scale.X, deltaManipulation.Scale.Y variables which come from ManipulationDelta event to have a number for zooming.
Because for zooming wpfextensions project easily handle when I call “zoomControl.Zoom = 0.5;” so by using scalex and scaley I need to have an integer value to zoom.
Or if anyone knows in wpfextensions’ zoom events, how should I call zoomControl.?? with which variables ?
