How to snap to VBAI from "run labview" step?

[mvonstein]

I have successfully done this before with a firewire camera, but the only way I could get it to work was to do a "simulate acq" from a previously snapped picture in VBAI and then pass that into the VI.

Is there a way to create the picture in Labview and pass it in to VBAI without having to pass a place-holding image variable in?

Thanks in advance.

Hello Mike,

VBAI does require you to insert the 'Simulate Acquisition' step and then pass the image reference to the 'Run LabVIEW VI' step in order to snap an image in LabVIEW as a VBAI step. It is necessary to have an image reference in VBAI before you can snap the image in LabVIEW.

Actually, the Run LabVIEW step can only update an image that is passed in, it cannot create a new image that can be used by VBAI. So currently, you have to pass in a dummy image if you want the Run LV step to update it and have an image produced by the Run LV step. This is a good suggestion though, and it will be evaluated for future releasses.

Thanks,

Brad
