Member Function Documentation

◆ close()

bool OpenCVWriter::close ( )

overridevirtual

Close the DeviceDriver.

Returns: true/false on success/failure.

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 64 of file OpenCVWriter.cpp.

◆ open()

bool OpenCVWriter::open ( yarp::os::Searchable & config )

overridevirtual

Open the DeviceDriver.

Parameters

config is a list of parameters for the device. Which parameters are effective for your device can vary. See device invocation examples. If there is no example for your device, you can run the "yarpdev" program with the verbose flag set to probe what parameters the device is checking. If that fails too, you'll need to read the source code (please nag one of the yarp developers to add documentation for your device).

Returns: true/false upon success/failure

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 41 of file OpenCVWriter.cpp.

◆ putImage()

bool OpenCVWriter::putImage ( yarp::sig::ImageOf< yarp::sig::PixelRgb > & image )

overridevirtual

Write an image to the device.

Parameters

image the image to write

Returns: true/false upon success/failure

Implements yarp::dev::IFrameWriterImage.
