Resize ROI with mouse without using ConstructROI

[Guntis]

I am using IMAQ and LabView to monitor temperature.

I am modifying FLIR (FSI Automation)'s example "Thermovision Analog IR Cam Config Example.vi", but adding ROI and using intensities for analysis. I would like to be able to resize ROI on the image without using ConstructROI. (Is there a way of using ConstructROI without the ROI sidebar and its buttons, ie is there a way to wire a value to the "ok" button)?

How about just resizing the ROI by grabbing the edge or corner and dragging it? You should be able to select the rectangle ROI tool, and the operator can either draw a new rectangle ROI or change the existing one. Just read the current ROI in frame 1 before doing any calculations.

Works perfectly! (It really is that simple).
