Set scan direction
Function
Changes the sequence from forward to backward (for example from R-G-B to
B-G-R), to adapt to the movement direction of a conveyor regarding to the
orientation of the camera.

Direction of the spatial correction depends on the direction of transport regarding to the
orientation of the camera, i.e. the sequence of the lines in the direction of transport can be
either red-green-blue (RGB) or blue-green-red (BGR) but the sequence can be changed, if
necessary. Then the color offset is been corrected, irrespective of the installation position of
the camera.
If the encoder is activated, the transport direction could determined in the encoder controller.
If the determined scan direction from the encoder doesn't match the scan direction in free
runnung mode, the scan direction from the encoder could be inverted with the I/O configurator
(Invert scan direction from encoder)
In addition the scan direction could aslo be set with a external pin by e.g. the motor control of
the system.
