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 )
Parameter
X, Y
Position of the rotation center referenced to the zero point (0|0) of the image
field as signed 32-bit values;
allowed range: [–2
24
… (2

–1)]
Comments • For Processing-on-the-fly correction, see page 181 .
• The position of the rotation center should be defined via set_rot_center or
set_rot_center_list before the Processing-on-the-fly correction is activated via
set_fly_rot or set_fly_rot_pos .
• The rotation center can also lie outside the image field (the allowed area is roughly
equivalent to 30x the image field).
• Usage of a second scan head is only practical if it is set up for exactly the same rotational
center.
