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

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
