Comments • For backward transformation of position values see
Positioning", page
• The execution of transform must be preceded by a call to upload_transform.
Additionally, position values should have been requested by get_values.
• If execution of transform results in an error (returned error code > 0), then no
transformation occurs (Sig1 and Sig2 then remain unchanged). Errors also include
Ptr =
upload_transform
• If backward transformation of z values is requested (Code Bit #0 = 1), but only a
2D correction table has been assigned at the timepoint of the prior successful call to
upload_transform, then the offsets to the focal length and z coordinates are
initialized with 0 and the values A, B and C are initialized with 0, 1, 0 (1-to-1 backward
transformation).
• For backward transformation of xy position values (Code Bit #0 = 0), only the z = 0
plane is transformed. xy stretching and Z defocus resulting from z deviations
(particularly with non-F-Theta systems) are not taken into account.

If Bit #0 = 1, then only one of the two supplied position values is backward
transformed as the z coordinate:
Bit #1 = 0: The value supplied by Sig1 is backward transformed
as the z coordinate. Sig2 remains unchanged.
The value supplied by Sig2 is backward transformed

as the z coordinate. Sig1 remains unchanged.
Bit #2 = 0: Offset to the focal length defined by
