When using the "get last event" method on a displayed image, I can't get a ROI input : the method never returns a type=2 and doesn't draw the rectangle on the image.
Moreover, I experience a behaviour I don't understand with the command array for the "which event" parameter : the left hand value is a digit, and switches the right hand value from "no event" to "draw event" and son on,.. but I can't understand what the right hand digit is exactly used for.
I want the method to let me draw a ROI and returns the coordinates, just like the "extract example.vi" - that came in the VISION application - does .
Many thansk in advance for any help
