Member Function Documentation

getRawBuffer()

virtual bool yarp::dev::IFrameGrabber::getRawBuffer ( unsigned char *  buffer )

pure virtual

Get the raw buffer from the frame grabber.

The driver returns a copy of the internal memory buffer acquired by the frame grabber, no post processing is applied (e.g. no color reconstruction/demosaicking). The user must allocate the buffer; the size of the buffer, in bytes, is determined by calling getRawBufferSize().

Parameters

buffer

pointer to the buffer to be filled (must be previously allocated)

Returns

true/false upon success/failure

getRawBufferSize()

virtual int yarp::dev::IFrameGrabber::getRawBufferSize ( )

pure virtual

Get the size of the card's internal buffer, the user should use this method to allocate the storage to contain a raw frame (getRawBuffer).

Returns

the size of the internal buffer, in bytes.

height()

virtual int yarp::dev::IFrameGrabber::height ( ) const

pure virtual

Return the height of each frame.

Returns

image height

width()

virtual int yarp::dev::IFrameGrabber::width ( ) const

pure virtual

Return the width of each frame.

Returns

image width
