private

publish()

void rc::ImagePublisher::publish ( const rcg::Buffer *  buffer, uint32_t  part, uint64_t  pixelformat  )

overridevirtual

Offers a buffer for publication.

It depends on the the kind of buffer data and the implementation and configuration of the sub-class if the data is published.

Parameters

buffer	Buffer with data to be published. The buffer is already attached to the nodemap for accessing the chunk data.
part	Part index of image.
pixelformat	The pixelformat as given by buffer->getPixelFormat(part).

Implements rc::GenICam2RosPublisher.

Definition at line 105 of file image_publisher.cpp.

requiresComponents()

void rc::ImagePublisher::requiresComponents ( int &  components, bool &  color  )

overridevirtual

Adds components and if color images are required to the given values.

Nothing will be changed if there are no subscribers, i.e. used() == false.

Parameters

components	Components Flags that will be updated according to the needs of this publisher.
color	Value that will be updated if this publisher needs color.

Implements rc::GenICam2RosPublisher.

Definition at line 87 of file image_publisher.cpp.

used()

bool rc::ImagePublisher::used ( )

overridevirtual

Returns true if there are subscribers to the topic.

Returns

True if there are subscribers.
