How to define a rectangle programmatically to use as a RIO

[Stephen1995]

Hi, 

I'm analysing a video and would like the option to either define a RIO by clicking and dragging on the video window or by using a default region. I've manage to do the click and drag but I can't set the rectangle to be the to corner of the video. Video resolutions change between files so I need to use the info from the width and height to define the coordinates . These values then need to be passed to the IMAQ convert rectangle to RIO. The problem is I cant write to the function in the rectangle data type. I tried a standard cluster of the 5 elements which are in the rectangle data type but this doesn't work. How do I do this? The picture shows the code I have. 

thanks 

Stephen

Covert the cluster to array of 4 elements then it will work for you

The above statement has to be reversed to make the concept work

I don't get why you are using Build cluster array instead of Bundle for cluster.
-The input to Rectangle to ROI is cluster of five elements, not cluster of array of five elements.
-no need of making array then converting to cluter.
-Just use bundle the five numbers using https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/functions/bundle.html
-let me know if that helps.
