How to change the image display position on FP programmatically?

[Anne Zuo]

Hi All,

I need to change the IMAQ image display on FP programmatically.  I check the property node and find out it is read-only. Is there a way to do that?

Thanks a lot for any help.

Dear Anne,

this should actually work with the property node. It works for the classis image indicator or display as well as for the modern one. I am currently working with LabVIEW V8.5 and I have just tried that property node and it is working fine.

Here is what you need to do:
a) Right click on the indicator and select create property node ==> "Position" and then "all elements".
b) By default, LabVIEW will place the node in read mode
c) Right click the "Position" node and select "Change all to write"

Now when you wire in values for "top" and "left" and execute your VI - it'll align the upper left corner with that pixel position of your front panel.

I hope that helps.

Best,

Hi Markus,

Thanks a lot for your help. It works. 

Yesterday I picked up the wrong property: display image position.

Cheers.
