extern C* value computed from them. The type of information is specified when* the variable is created. Multiple instances of this class can be * created They all share a common window but can access different * fields of the image * * This class can probably be improved in speed by constructing a more * direct connection between the framegrabber and the monitor Also * this class uses frames in a nonstandard way : a data pointer to * released frames is maintained although the frame is again in use * by the framegrabber. * * Many Video base class functions are left undefined. * class DT3155 public MonoVideo
