vision builder

Hi there,
I need to make zoom in and zoom out in an acquired image that I show in my Vision Builder AI-Inspection, but the problem is that there is no control button in my graphical user interface that can allow me to do that. I know that it is possible to have this type of controls in a GUI, because there is some examples in the "built in inspection interface", that do that, (but I'm not allowed to access to this built in inspection interface, to see How it works!)
Can anyone help me?
** I attached a picture for you guys realize what I really need.
Regards

With VBAI 2009 you have Zoom Tools in the Inspection Interface too.

See here at page 21.

Hi,

Is you GUI a "Custom Inspection Interface" or the normal "Inspection Interface"?

Because if you use a custom interface, you have different way of doing it.

Either you use the ROI Tool bar of your image control in which you find a zoom tool.

Either you place two buttons on your GUI that controls property node of your image. (ZoomInteger or ZoomSingle property node)

Now I do not have VBAI2009 installed anymore, but if you use the normal inspection interface, you should be able to zoom in and out.

Hope this helps

Regards

Hi
I have already tried what you are saying (create a zoom tool) in my interface with labVIEW, but didn't work because VB doesn't accept subVI, and zoom tool is one.
thanks

Hi Christian

In page 21, the inspection is a built-in inspection interface which already has the zoom controls.

If you try to create a new Inspection interface, the controls doesn't appear

You defenitely have two options:

1. Use the standard configuration interface, which natively provide zoom tools.

2. As toto said, create a custom interface using the IMAQ Image display, which also provides zoom tools.

Christian, if I use the standard configuration, I'm restricted, because I will need other functionalities in my configuration inspection.
In other hand if I use buttons from labVIEW, to control the zoom, as I said to toto, I will get an error because I can´t use subVI in VB.

As I said before, when creating a custom inspection interface, the IMAQ Image display includes zoom tools:

Hello again Christian,

I have done what you suggested. And it works, I didn't get any error or something like that. But the problem still persiste, because with the tools given by the IMAQ, I only can do a zoom in. Where can I change the zoom that I´m looking for?

Hi,

To zoom out, just press the Caps key and clic on your image... I agree it's not very intuitive.

You can right click on an image display control and select the ROI tools to be visible. The Oom ones are included in there. Hope that helps

Sorry I missed the additional comments. You could also implement your own Zoom with a button and property nodes for the image display xomtr
