◆ getImage()

◆ 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
cropTypeenum specifying how the crop shall be generated
verticesthe input coordinate (u,v) required by the cropType
imagethe image to be filled
Returns
true/false upon success/failure
