Hi,

If your camera API provides easy interface with IDL via a DLM that you
can code up (this is beginning to look like alphabet soup!) then yes. I
have done this kind of thing with the SCION frame grabber. After you
have your DLM set up, you can simply call for a new image ala newImage =
MyDLM_GetImage() or some such call. Then use object graphics to render
the image to screen (which I think is faster for images than direct
graphics). I never achieved full frame rate video display, but it was
fast enough for my purposes.

I'll bet there are faster/better ways to do this but I found it pretty
easy to manage.

I have no idea about passing an IDL graphics window to MS Windows - but
isn't there some kind of ActiveX thing for IDL connection to Windows?

Cheers,
Ben
