transform is a ROS node that subscribes to a topic, or a topic field, and publishes incoming data to another topic, after applying a given Python expression. It's mainly useful for simple message transformation, like computing the norm of a vector or quaternion, or even converting a quaternion to Euler angles. It can work with any message type.

transform is part of topic_tools.
