Member Function Documentation

getImage()

template<typename ImageType >

virtual bool yarp::dev::IFrameGrabberOf< ImageType >::getImage ( ImageType &  image )

pure virtual

Get an image from the frame grabber.

Parameters

image

the image to be filled

Returns

true/false upon success/failure

Implemented in FrameGrabberOf_ForwarderWithStream< yarp::sig::ImageOf< yarp::sig::PixelRgb > >, FrameGrabberOf_ForwarderWithStream< yarp::sig::ImageOf< yarp::sig::PixelMono >, VOCAB_FRAMEGRABBER_IMAGERAW >, FrameGrabberOf_ForwarderWithStream< yarp::sig::ImageOf< yarp::sig::PixelFloat > >, FrameGrabberOf_ForwarderWithStream< yarp::sig::FlexImage >, FrameGrabberOf_ForwarderWithStream< ImageType, IfVocab, ImgVocab >, FrameGrabberCropperOf< ImageType >, yarp::proto::framegrabber::FrameGrabberOf_Forwarder< ImageType, IfVocab, ImgVocab >, and yarp::proto::framegrabber::FrameGrabberOf_Forwarder< ImageType, VOCAB_FRAMEGRABBER_IMAGE, VOCAB_RGB_IMAGE >.

getImageCrop()

template<typename ImageType >

bool yarp::dev::IFrameGrabberOf< ImageType >::getImageCrop ( cropType_id_t  cropType, yarp::sig::VectorOf< std::pair< int, int >>  vertices, ImageType &  image  )

virtual

Get a crop of the image from the frame grabber.

Note: this is not configuring the camera sensor to acquire a crop of the image, nor to generate a cropped version of the streaming. Instead, the full image is acquired and then a crop is created from it. If the hardware supports it, it is possible to override this method and request a hardware crop.

Parameters

cropType	enum specifying how the crop shall be generated
vertices	the input coordinate (u,v) required by the cropType
image	the image to be filled

Returns

true/false upon success/failure

Reimplemented in FrameGrabberOf_ForwarderWithStream< yarp::sig::ImageOf< yarp::sig::PixelRgb > >, FrameGrabberOf_ForwarderWithStream< yarp::sig::ImageOf< yarp::sig::PixelMono >, VOCAB_FRAMEGRABBER_IMAGERAW >, FrameGrabberOf_ForwarderWithStream< yarp::sig::ImageOf< yarp::sig::PixelFloat > >, FrameGrabberOf_ForwarderWithStream< yarp::sig::FlexImage >, FrameGrabberOf_ForwarderWithStream< ImageType, IfVocab, ImgVocab >, yarp::proto::framegrabber::FrameGrabberOf_Forwarder< ImageType, IfVocab, ImgVocab >, and yarp::proto::framegrabber::FrameGrabberOf_Forwarder< ImageType, VOCAB_FRAMEGRABBER_IMAGE, VOCAB_RGB_IMAGE >.
