With "Vision utilities" I'm trying to create a scaled scrollbar in Live video with Overlay I got it up to a point but I couldn't do exactly what I wanted. The problem is that the numbers are repeated but I haven't been able to create full synchronization. sample code here
Solved! Go to Solution.
You have an image, Grab, and add an overlay to it. Then, next iteration, you add an overlay to it, this is repeated. The overlay is never cleared. Those IMAQ references are funky... It's not by value.
So clear the overlay before adding to the overlay...
You can use a control\indicator, and then get it's bitmap, and draw it in the image.
You can try to simply put the control over the IMAQ image. Or get the pixels of the image, and draw them in a picture control (you'll loose a lot of functionality).
Sorry, I don't have NI Vision installed at the moment.
