I try saving the IMAQ image that has some overlay to jpeg file (and want the overlay to be displayed while I open jpeg file with application other than LabVIEW). I got one example code from ni website, but when I tried the same method with my program, it saves everything on the screen to my jpeg file (just like when u press print screen button on your keyboard, not saving only the selected window eventhough I specify the window number at the IMAQ Overlay to Image.VI). Can you suggest me what parameter I should set to save only the selected window?
