Returns an image of a front panel object.

This method is similar to the Front Panel:Get Image method.

If a front panel is not visible, LabVIEW does not update the values in the objects on the front panel. If you call a VI whose front panel is not visible and you use the Get Image method to create an image of a front panel object, the image does not reflect any value changes that occurred when you ran the VI.

If you want the image to reflect value changes, make sure the front panel is open before any values change. If you do not want to display the front panel but want the image to reflect value changes, create a Property Node from any terminal on the block diagram of the VI for which you want to create a front panel control image.

You also can use the Append Control Image to Report VI to create an image of a front panel object and append it to a report.
