Public Functions

inline IMAGE_TRANSPORT_PUBLIC TransportHints(const rclcpp::Node *node, const std::string &default_transport = "raw", const std::string &parameter_name = "image_transport")

Constructor.

The default transport can be overridden by setting a certain parameter to the name of the desired transport. By default this parameter is named “image_transport” in the node’s local namespace. For consistency across ROS applications, the name of this parameter should not be changed without good reason.

Parameters:

  • node – Node to use when looking up the transport parameter.

  • default_transport – Preferred transport to use

  • parameter_name – The name of the transport parameter
