Interface class for head display

Displays a given image file or multiple files on the robot's face.

Pass the relative or absolute file path to an image file on your computer, and the example will read and convert the image using cv_bridge, sending it to the screen as a standard ROS Image Message.

Notes: Max screen resolution is 1024x600. Images are always aligned to the top-left corner. Image formats are those supported by OpenCv - LoadImage().
