I see in the API docs there is the ability to convert world coordinates to screen however is there a way to go in the opposite direction?
I am interested in building an interface to allow users to create there own annotations on the fly thru the regular viewer. Step 1 to this would be having the user click on a spot within the viewer to mark the position of the annotation. Of course at that point I would only have the screen coordinates and my final annotation to save will need the world coords.
Is there any way to do this thru the API or even without it thru some other means?
