How does one display multiple rois in an image?

I'm trying to display multiple ROIs overlayed on top of an image. The trick, as I see it, is doing this without the full fledged version of IMAQ Vision. I can extract the ROI information from a property node and enter this information in an array that is updated as the roi's are updated. However, my attempts to display all the former ROIs fail and only the last one is displayed. I've reviewd the Help files and there's nothing in them regarding working with ROIs, probably becasue we don't have the full version of Vision. Any thoughts on how I can go about doing this would be appreciated.

Here's the code. There's no image so it won't execute, but you can at least see what's happening.

Hey Mike,

If you haven't already, check out my reply to the same message that you have posted on the Machine Vision Board.  In the future, please try to limit your postings to one thread per issue.

Thanks!

Robert
