Is there any way to control how graphics like bitmaps are layered? It seems like what ever was created most recently is automatically brought to the top. I'm not talking about the "bring to front" in the front panel. What I want to do is be able to control some sort of value while the program is running. Is this possible, even by doing something tricky? Thanks

If they're opaque then why not just hide the one you want to move back?
If they're not opaque you could use selectors to direct V outputs to a set of pre-ordered layers.

Hey Oddson, Thanks for the reply.
The first suggestion doesn't work due to the nature of the program I'm making. Think of it as a photo viewer, where the photos can be moved around, scaled, rotated, etc. And you can have as many on the screen as you want. They aren't directly stacked on top of one another.
The second suggestion looks good, but with a large number of images I'm guessing that could become a pain in the butt.

So the layers need to overlap (so hiding's not an option).
What determines the order? How many can you have at once?

Well I'm using ReacTIVisionsoftware to locate markers on a transparent tabletop. There are a bunch of markers (little cubes with images on bottom) and each one represents an image that will show up on the screen. The most basic control over layering would be the last one placed on the table is on top. (Back to front in order of placement on the table) I'm not sure how to achieve that when I'm not quite sure how many images we're talking about (between 5 and 10 most likely).

Alright I think I just had a eureka moment regarding this. I will have each marker output a 1 when placed on the table and have them summed up. The view for that image will go to a multiplexer where it is sent through the output of that summed up value at the moment it is placed on the table. Anyway, I think I have the basic idea, time to test it out. Definitely branching off of your suggestion above, thank you.

Got it working! And it was even easier to do than I thought. Man I love this program.

I made a separate thread about the completion of this project, if anyone is interested.
