I'm looking to extend a Deep Zoom MultiScaleImage so that the user can draw selections and rotate the MSI. I've managed to do something similar in the past with images, but the MSI control is giving me some pain.
I've followed the pretty excellent tutorial here for putting overlays on top of an MSI but I am having problems with the overlays when the window is resized. There is something on this in the comments, but it doesn't appear to actually work. I'm also having problems trying to handle rotation so that the mouse still works as expected and so that the overlay stuff appears correctly.
Any help on either of these would be most appreciated!
