conflicts between property nodes

[anne.M]

I am using property nodes on image display to set the position center ( X and Y ) and the zoom (X and Y). When using only position center property nodes everything works fine , but if i set the zoom value with property nodes the position center doesn't work any more, the image stays in the default position.
Is there any known reason for this behavior?
I am using Laview 7 under windows 2000 professionnel, and i am acquiring an image with a PCI 1408 card.
Thanks,

Are you using property nodes or IMAQ Display functions? I couldn't find any property node "position center". Can you post your code?

I am using property nodes, X and Y position center can be found in the last sections of property nodes at "image center position". I have posted my code here.

Try exchanging the two sets of properties (zoom and center x,y) - property nodes execute from top to bottom. You will also want to make sure that the error cluster is connected so that the property node does not execute until the image has been acquired.
