# image_common

#### Description
image_common should always be used to subscribe to and publish images. It provides transparent support for transporting images in low-bandwidth compressed formats. Examples (provided by separate plugin packages) include JPEG/PNG compression and Theora streaming video.When working with images we often want specialized transport strategies, such as using image compression or streaming video codecs. image_common provides classes and nodes for transporting images in arbitrary over-the-wire representations, while abstracting this complexity so that the developer only sees sensor_msgs/Image messages.

#### Software Architecture
Software architecture description

image_common should always be used to publish and subscribe to images. At this basic level of usage, it is very similar to using ROS Publishers and Subscribers. Using image_common instead of the ROS primitives, however, gives you great flexibility in how images are communicated between nodes.
