Number of the scan head connector as an unsigned 32-bit value:
= 1: The definition only affects the primary scan head connector.
= 2: The definition only affects the secondary scan head connector
(activation required)
= 0, 3: The definition affects both scan head connectors.
Only the two least significant bits are evaluated.
Rotation angle in ° (as a 64-bit IEEE floating point value); positive angles result
in a counterclockwise rotation around the centerpoint of the image field.
This parameter (unsigned 32-bit value) determines when the defined
transformation becomes effective:
= 0: The new total transformation (total matrix and offset) is only
calculated and applied to the current position when the next list
command is executed.
= 1: The new total transformation is calculated immediately (or before the
next list command if a list is currently BUSY or the board is INTERNAL-
BUSY) and applied to the current position. The "laser active"
laser control signals will first be switched off if necessary.
= 2: The new total transformation (total matrix and offset) is only
calculated and applied to the current position when the next
jump_abs, jump_rel,
= 3: As with at_once = 1, but the laser control signals remain unaffected.
