3.3. Grab Functions
3.3.1. Overview: Grab functions
Grab functions allow the user to capture streamed data from the digital camera.
The grab process may be performed in two ways:
 Synchronous: calling SvGrabFrame function.
 Asynchronous: calling SvQueuFrame function.
Both methods use the SV_FRAME structure to grab the data.
SvGrabOneFrame grabs one frame synchronously.
SvQueueOneFrame grabs one frame asynchronously.
SvAbortGrab aborts any pending asynchronous grab.
SvTrigger triggers a camera exposure.
