manually change ROI position

Hi...

I was trying to change the ROI position in LabVIEW .

I dont know whats wrong with the Image control.

I have made the ROI offset (x,y) position so that it can change the vertical and horizontal postion of the ROI pattern. It is changing the position but in the Image it is unable to clear the old ROI positions.

I have attached my ZIP file containing VI and image please help me on this.

Hi saran1988

Using Vision Express VIs have there own limitations.

Setting up a manual ROI in express VI is difficult.

Why dont you use the VI attached in my first post?

All you have to do is put the code inside your producer consumer loop and add "IMAQ Clear Overlay.vi."

You're posting on a thread that is a year old. If you're getting any replies, you're lucky. Either be patient or spend a few minutes to go over the last post they sent you and try to understand it. It's not reasonable for you to demand they reply quickly to hold your hand. Learn to use Ctrl+H to understand the tools they provided you. At some point, you'll need to be able to understand what you're doing.
