Introduction

This VI shows you how to use the ROI tools of the Front Panel Image Control to create an ROI. Then you can programmatically take the coordinates from this ROI to process your image further.  In this example, the coordinates from the ROI are used to overlay a rectangle onto the original image.

Steps to Complete

Open the attached VI and follow the instructions on the front panel.

Additional Notes

This VI was written in LabVIEW 8.6 and using the Vision Development Module 8.6.

Hope this helps.
-Ben
