Can you help me understand how this works then? When you have time. I put in a picture that was a solid red JPEG and selected vector. Are there other settings to make it move or am I not understanding how this works? Your animated GIF that you showed for the white line just showed that you put in a white line and selected vector and it was moving back and forth. I guess I didn't see a directionality selection.
Thanks,
