Detailed Description
When used to specify the ROI setting of the camera when the image was taken, the height and width fields should either match the height and width fields for the associated image; or height = width = 0 indicates that the full resolution image was captured.
RegionOfInterestPublisher publishes regionOfInterest values to a ROS 2 topic. Set the topic and node properties, then call publish() to send messages.
See also RegionOfInterestSubscriber and regionOfInterest.
