IMAQ zoom function

[GaryTan]

Hi everyone, I'm back again with question

Anyone know how to use the IMAQ WindZoom Fucntion? Can explain it?

As I need to use the zoom in and out function to analysis an image. The built-in function which appears on the display panel can only zoom in and no zoom out.

Thx

Hello,

To zoom out, select the zoom tool, hold the shit key and clic on the image display.

The major drawback of this is that you cannot control the zoom factor accurately. To be more accurate you have to do it with a property node on the image display and use the SGL zoom factor (you can even use different factors on X and Y).

Hope this helps

If you have Vision 8.6, there is a new "zoom-to-fit" option for displaying images. I haven't tried it on a Window yet, but it works great on the IMAQ Image Display.

Note there is already an update Vision 8.6.1
