IFC
IFC parameters for Data Port Sequencer Table:
CL2_IMAGE_GEOMETRY = {CL2_1CHAN_L2R, CL2_2CHAN_INTERLEAVED,
CL2_2CHAN_SEP_TAP_L2R, CL2_2TAP_INTERLINE_A_EVEN,
CL2_2TAP_INTERLINE_B_EVEN}
P_PIXEL_SIZE: pixel size of host buffer from 8 to 16 bits
P_CAM_PIXEL_SIZE: pixel size from camera, 0 if camera has same pixel size as host
buffer
P_PIXEL_COLOR = {IFC_MONO}
Window Generator
The Window Generator extracts a window from the incoming image. This window is represented by a
rectangle where the upper-left corner is set by horizontal and vertical offset from the start of valid
video and the rectangle size by width and height parameters. See diagram below. Note that image
widths must be a multiple of four bytes because of transfer restrictions on the PCI bus.

Figure 14: Window Generator
Window Generator operates after the channels have been recombined by the data port sequencer;
therefore, image width and height applies to this recombined image, not to individual channels.
