Description

You can use this function only in the "onDrop" script of a video EWO. If you add the function to the script, the EWO will open a live image as soon as a camera data point is dropped to the EWO (e.g. to a camera symbol). The parameter dialogIdx specifies in which dialog the image will be opened. If the parameter is 0 or you do not pass it, the image will be opened in the active dialog. Otherwise the image will be opened in the passed dialog.
