zoom out in "imaq select rectangle" tool

[aw_ipt]

Hello,

I want to show the user the imaq select rectangle tool to select a ROI. The Imagesize is 2 Megapixel, so its to big for the screen. How can I reduce the size (zooming out and fitting the border to the zoomed out image) automatically so that the user does not have to use the manual zoom tool first?

Regards,

Andreas

use a property node and a zoom control

Hello! Thanx for the fast answer. I already tried to use the proporty-node, but what is the reference fot the node?

Just right click on the image out icon. Choose -->create--->property node---> zoom---> all elements

Hello! Thanx again. But I use the "imaq select rectangle" tool. I used the way you discribed for setting my frontpanel image-displays to the "zoom to fit" mode. But I really don't know how to do that for this imaq VI. This option for zooming does not exist. If I do a right-click on the Image Output of the "imaq select rectangle"-VI, there are only the 4 image proporties (like "border size"). So how exactly can I solve the problem?

r u looking for this? I am getting a feeling that I am not understanding your exact requirement

Hi! Thank you for your effort. But this was not the point I was talking about. I'm talking about the integrated SubVI "imaq select rectangle". But it seems to be impossible to get proporty-notes to a sub-VI without opening it before. I now did a work-around with the "IMAQ ConstructROI" using the integrated VI's to change the zoom. But thanx anyway.

Strange, it works with IMAQ Select Rectangle exactly so good as with IMAQ ConstructROI:

 

Otherwise you can build VI with such dialog yourself and better. Good LabVIEW exercise.

Hi, everyone.

i know that this is an old thread, but i hope that you can help me.

I am using an ids camera and therefore the ids functions to get a 2D Image Array, which is transformed with the function Array to Color Image form the Vision Toolbox.

I want to use the property node to create a zoom function, so that the zoom can be adjusted much finer than with the mouse click on the image.

The problem is, that I can't use the scroll bars of the image anymore. They always jump to the left upper corner or the right upper corner.

If i don't use the zoom property node i can use the scroll bars

I attached two pictures of the ids examples i am using to test that.

thanks

sam

Oh, i use labview 8.6
