I am looking for a USB camera/software package that lets you determine the pixel address (row/column) of a particular point in the on screen video display. Ideally this could be done by positioning the cursor over the point of interest. Any ideas?
This is a trivial operation, as the mere act of rendering each frame requires the software's knowledge of pixel locations. It's akin to a browser displaying the URL of a hyperlink. It's also the kind of function that most casual users don't need, so it may not be implemented.
Or, it might be turned off by default, like the status bar in some programs. Look into the View menu or similar of whatever software you do have to see if it's something you can enable.
If you had the source code of the package, you could implement it without much trouble. In fact, I do believe a savvy Windows programmer could write such a feature that works with every window on screen, and it shouldn't take too long. I wouldn't be surprised if such a mini-app doesn't already exist.
I apologize if this doesn't help you at all.

Thanks for the response. I've thought about writing something in vb (I'm not much of a programmer) to display a screen capture from the camera software in a window and then report cursor position, or I could save the capture and view it in MS photo editor which has this feature. I was hoping that somebody had already done the work so it would all be in one seamless package. But I've done some web searches and found nothing yet. As you say this is not a feature that most people would need. Anyway I am encouraged that this is probably not very difficult.
