Detailed Description

This class provides the CCD47 framegrabber which writes to a sharedim_stack. Manages the EDT PCI DVI framegrabber card.

In addition to the framegrabber config file options, has:

• num_bufs int [4] - the number of DMA buffers allocated by the EDT driver

See VisAOApp_standalone for command line arguments. There are no additional command line arguments for a basic framegrabber, though derived clases may add them.

See framegrabber for the commands accepted by this class.
