Member Function Documentation

◆ getTransportName()

virtual std::string ResizedPublisher::getTransportName ( ) const
inlinevirtual

Get a string identifier for the transport provided by this plugin.

Implements image_transport::PublisherPlugin.

Definition at line 7 of file resized_publisher.h.

◆ publish()

void ResizedPublisher::publish ( const sensor_msgs::Image &  message,
const PublishFn publish_fn 
) const
protectedvirtual

Publish an image using the specified publish function. Must be implemented by the subclass.

The PublishFn publishes the transport-specific message type. This indirection allows SimpleSubscriberPlugin to use this function for both normal broadcast publishing and single subscriber publishing (in subscription callbacks).

Implements image_transport::SimplePublisherPlugin< image_transport_tutorial::ResizedImage >.
