cursor

[femtovahan]

Hello,

I want to implement multiple drag-able cursors on the image graph (from a CCD camera) during image acquisition. I need the cursor (cross) for laser beam alignment on the camera. I want it to be drag-able and/or to be able to set the X,Y coordinates of the center of the cursor to move it to the desired position on the image.

What are the easiest options? I am using LV 2009.

Thanks!

femtovahan-

Are you using the NI Vision Acquisition Software for the image acquisition with your camera?

[femtovahan]

Yes, I do use Vision.

Thanks,

Never mind, I figured a way to implement this using IMAQ Overlay features.

In case someone needs it, see attached. This can be usaed as a sub VI for displaying the cross on the image, specifying the X and Y coordinates of the center of the cross.

Thanks!

Hello, I'm using labview 8.5 and can't view the vi that you've made. I was wondering if it would be possible for you to post an image of the vi so that I can have a look at it. Thanks

Sure, see attached. Let me know if you still can't make it work.
