in fact I've swapped the horizontal yoke wires on a few old b&w TVs to make prompter monitors, and it's very simple. You should be able to just do that in a loop and draw the bitmap to the screen instead of saving it.

IntPtr hOld = (IntPtr)SelectObject(hMemDC, hBitmap) īitmap image = .Png) IntPtr hBitmap = CreateCompatibleBitmap(hDC, width, height) IntPtr hWnd = GetMainWindowHandle("winword") Here is a little sample app (pinvoke declarations left out) which will just take the snapshot once and write it to a file: static void Main() You would just need to use the PrintWindow function. It should be pretty easy to write a program that will take a specific program, capture its window (even if there is a window in front of it, such as your app which will display the flipped version), and flip it. I've seen plenty of cards that do rotation, but not mirroring. Regarding xrandr, I believe this requires finding a video adapter that supports mirroring. On Linux, none of this would be an issue because you can just use vncserver, which acts as a virtual X server. One way to work around this would be to put the window to be reversed on a second display, but then you run into a couple of potential different problems: having a second display taking up space, or getting Windows to let you use a 2nd display output without hardware hooked up and dealing with the difficulty of putting the window to be reversed on that 2nd display without being able to see it. So if you wanted to reverse Word, you'd have to have it displaying normally on half of the screen, and the reverser application displaying in the other half. The problem (so far as I know) is that there's no way for one process to make another process draw a window into an offscreen buffer - all you can do is capture a region of the screen. The main problem with this that I'm not sure if it could be done on Windows.

I'm not really a programmer, so I have no idea how to do this, let alone turning it into a dynamic, full-screen 30-60fps standalone app, but it's exactly what I want. Hat Monster pointed out that capturing the framebuffer is simple, and that flipping an image is also simple.

Print your "screen" to a buffer and then have your software reorder the bits to the video hardware. The other option of course is to do everything in software. Failing that, you could use openoffice, or word under wine or similar.

If that is the case, it should be possible to do the same under windows, I just don't know what program would do it. Under Linux, xrandr can do this under X, and I think it is done by bit-twiddling in the video card, rather than drawing the whole frame buffer backwards. This unfortunately isn't the same as a rotated image, which is flipped horizontally *and* vertically. Since mirrors reverse images, you need to display a flipped image. The camera also sees a reflected image, but that is of a black "beam dump", so it just sees the subject.

The subject can read off of a screen reflected in the mirror while looking directly into the camera.

Maybe I'm missing something as I'm not in this business, so an explanation of why a mirror is needed might be helpful.Ī teleprompter works by placing a partial reflecting mirror in front of a TV camera. With Flat panel technology the need for a mirror would seem to disappear.
