Embedding Windraw in a child window, or other video tearing solutions?

[Patrick_Lu]

When I display video from a camera in an imaq image indicator on the front panel, I get obvious video tearing for fast-moving objects (like waving a hand). After some googling, I tried using WinDraw and WindNonTearing. While this does work, for the esthetics of the UI, I don’t want the video to show up in a separate pop-up window. How do I include the WinDraw window as a subpanel on my front panel? Or, is there something else I should be trying? I did find a former post someone made about making WinDraw a child window using DLL calls, but it didn’t go into enough specifics and I wasn’t sure how to do it.

Hi Patrick_Lu,

I’m not aware of a method of embedding a WinDraw window into the Front Panel, but I found something similar to the method you described. I’ve linked it below incase this was not what you were referencing, and haven’t seen it.

Another option you might consider is using the IMAQ WindMove to have the WinDraw window appear in a desired location.

I hope this helps!

Yeah, that was the one I was referring to :). Didn't fully understand it, and I I'm leery about trying DLL calls that I don't fully understand.
