SGGetGWorld

The SGGetGWorld function allows you to determine the graphics port and device for a sequence grabber component.

pascal ComponentResult SGGetGWorld (SeqGrabComponent s, 
                                     CGrafPtr *gp, GDHandle *gd);

s

Specifies the component instance that identifies your connection to the sequence grabber component. You obtain this value from the Component Manager's OpenDefaultComponent or OpenComponent function.

gp

Contains a pointer to a location that is to receive a pointer to the destination graphics port. Set this parameter to nil if you are not interested in this information.

gd

Contains a pointer to a location that is to receive a handle to the destination graphics device. Set this parameter to nil if you are not interested in this information.

DESCRIPTION

The sequence grabber component displays the recorded or previewed data in this graphics world.

SEE ALSO

You can establish the graphics port and device for a sequence grabber component by calling the SGSetGWorld function, which is described in the previous section.
