I am working on a project which allows user to Zoom in and Zoom out at mouse location (which I have achieved through RenderTransform ans ScaleTransform). Next I would like to have a small window on top of the screen which shows the entire canvas and the
zoomed area in a highlight box, which I should be able to grab and move to change my zoomed area on the canvas. I have seen this in many applications but have no idea how to go about..
Any help is greatly appreciated!
