Selecting which image to display

[bikekowal]

Hi,

I have a following issue. I have a VI that displays three images (all of them have the same size). I can display every image in selected Image Display from Vision palette. As you can see in the picture below two Image Displays have the same size, and one is bigger. 

What I want to achieve is the ability to select (via using e.g. buttons) which image should be diplayed in which Image Display. For example when I push the 'Image1' button  then first image is displayed in the biggest Image Display (both rest images are diplayed in smalled Image Displays). When I push  the 'Image2' button  then second image is displayed in the biggest Image Display, and so on... Is it possible to do it?

Hi bike,

yes, it's possible!

You just need to program that behaviour...

hah 🙂 OK. It is good to know that this is possible. But any ideas how to do it? Any suggestions?

Hi bike,

well, I would start with a case structure.

There might be other options too, but I think you will explore them when time comes...

I thought about event structure, but it is good to ask someone more experienced before building the app...

Hi bike,

you can use the event structure to capture the button "value change" event (which is a different topic), but you will still need a case structure to select which image to display in which indicator...

Ok, I think it's time to start building the app. Thanks a lot

Hi GerdW,

I used case structure, but It doesn't work as it should work. Can you look at the VI from attachment?

Hi bike,

what's wrong with your VI?

You have programmed a certain order of image display in those indicators and you can select that order by a control. When you need other selections you have just to create more cases in the case structure. With 3 images in 3 indicators there are just 6 combinations...

Hi,

Take a look at the attached VI. You should study more about flowcontrol so that you get rid of the sequence structure. I don't have IMAQ so I can't test my example.
