I'm trying to trigger an event if the cursor is located in a certain part of an image in WPF. I thought I might try to "draw" an rectangle over the image and use a mousein/out event. I currently don't know how to accomplish this.   

So for example I want to trigger a tooltip if the cursor enters the red rectangle of the image.

Currently I'm using the `<Image></Image>` Tag in WPF but that does not seem to work out....   

Any help is appreciated!
