Video Lines Reordering
Applies to: 
Grablink frame grabbers are capable to reorder video lines during the transfer from internal FIFO buffer to the MultiCam buffer.
The reordeing is controlled by two Channel parameters of the Cluster category: FifoOrdering and FifoOrderingYTapCount.
The following reordering schemes are supported:
PROGRESSIVE
When FifoOrdering is set to PROGRESSIVE, the video data lines delivered by the camera are not reordered: the line order in the MultiCam buffer corresponds to the line order at the Camera output and to the line order on the sensor.
This is the default setting automatically invoked by MultiCam.
FifoOrderingYTapCount is irrelevant.
DUALYEND
When FifoOrdering is set to DUALYEND, the video data lines delivered by the camera using the *_2YE tap geometry are reordered in the progressive order. After re-ordering, the line order in the MultiCam buffer corresponds to the line order on the sensor.
This setting is enforced by MultiCam for area-scan cameras having a TapGeometry value terminated by _2YE. Refer to Image Reconstruction.
FifoOrderingYTapCount is forced to 2 and cannot be changed.
NYTAP
When FifoOrdering is set to NYTAP and FifoOrderingYTapCount is set to any integer value N, the video data lines delivered by the camera in block of N lines are stored into N separate color planes in the MultiCam surface.
The above drawing shows an example with FifoOrderingYTapCount = 5.
The PENTAYTAP value is kept for backward compatibility.
