Snap
The low-level snap examples set up a one-shot, single-image acquisition
and start the acquisition. The program acquires an image and processes it.
Finally, the program stops the acquisition, unconfigures the acquisition,
and closes the session.
Figure 2-5 illustrates the programming order of a low-level snap
acquisition.
