Ctrl Command set_rot_center
Function Sets the rotation center of a Processing-on-the-fly rotation correction (see set_fly_rot and
set_fly_rot_pos).
Call set_rot_center( X, Y )
Parameters X Position of the rotation center referenced to the zero point (0|0) of the Image
Field.
As a signed 32-bit value.
Allowed value range: [–2
24
…(2
24
–1)].
Y Like X (analogously).
Comments • For Processing-on-the-fly correction, see Chapter 8.6.3 ”Compensating Rotary
Movements”, page 247.
• The position of the rotation center should be defined by set_rot_center or
set_rot_center_list before the Processing-on-the-fly correction is activated by
set_fly_rot or set_fly_rot_pos.
• The rotation center can also lie outside the Image Field. The allowed area is equivalent
to 32x the Image Field.
• Usage of a second scan head is only practical if it is set up for exactly the same
rotational center.
RTC4RTC6 Unchanged functionality. In addition: increased value range.
In RTC4 Compatibility Mode, the RTC6 multiplies the specified values for X and Y by 16.
The allowed value range decreases accordingly.
