Ctrl Command set_angle
Function
uses a specified rotation angle to define the rotation matrix M
R
for all subsequent
coordinate transformations (see
"Coordinate Transformations", page 161
).
Call
set_angle( HeadNo, Angle, at_once )
Parameters
HeadNo
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.
Angle
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.
at_once
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
command is executed.
= 3:
As with
at_once
= 1, but the laser control signals remain unaffected.
> 3:

= 2
