How to setup Json file for the component "RosToImage"

Could you help with setting up the Json configuration for the component “RosToImage”. I was able to use app: camera_to_ros, but couldn’t able to create ros_to_image.app.json.

The ros_to_superpixels.app.json would be a good template to follow and invert camera_to_ros.app.json. Are you having any specific issues or just looking for an example?
