Change ROI position pressing a button

[A.Salcedo]

Hello everyone.

I have a program where user can select the position of some ROIs and then the program measure the distance of the edges that are inside the ROIs.

Well. Now I would like to have two displays. In one display I would like to visualize the image with the ROIs, this display 1 has to rec continously. And in the other Display (Display 2),  I would like to have just a image with the patron of an image where the user will be able to change the ROIs in this display.

So I would like that the user change the ROIs in the display 2 then press a buttón and the new ROIs has to be changed in the display 1 as well but just when user press a button, if the user does not press the button the ROIs in the display 1 has to be the same and do not change until user press a button.

How can I do that?

Any ideas?'

Thanks a lot!!

have a look at this VI, you need to create 2 image buffers, one for each display control, and for each display control you can create property nodes to read or write the ROI you want.

Hope this helps
