I wonder how I can zoom in a selected area programaticaly. I know how to zoom in but I also would like the area to be the center.

Regards

You can programmatically scroll the BitmapViewer using HScrollPos and VScrollPos properties. So you should just analyze the selection dimensions (SelectionWidth and SelectionHeight) to calculate zoom ratio and the selection position (SelectionLeft and SelectionTop) to calculate where to scroll.

Hope this helps.
