8 Advanced Functions for Scan Head Control and Laser Control

• Coordinate transformations are applied to all
to-be-outputted coordinates from all
Vector Commands ([*]jump[*] or [*]mark[*]
list commands, but also goto_xy or goto_xyz)
and “Arc” Commands. See also Chapter 7.3.6
”Output Values to the Scan System”, page 181.
• With a scaling matrix, the effective jump speed
and mark speed changes.
• With 3D vector commands:
– The transformation matrix only affects the x
and y components
– The offset affects all three components
• In order to utilize the complete real Image Field
with coordinate transformations (such as
rotations, shrinkages or shifts), the extended
value range of the virtual Image Field can be used
even without Processing-on-the-fly, see
Chapter 7.3.3 ”Virtual Image Field”, page 169.
• Coordinate transformations for the virtual Image
Field can be defined, see Section ”Coordinate
Transformations in the Virtual Image Field”,
page 169.
See also 4 in Chapter 7.3.6 ”Output Values to the
Scan System”, page 181.
Notes for RTC4 Users
• With RTC6 PCIe Boards, coordinate
transformations can no longer be set upon
loading a correction file by load_correction_file.
Instead, coordinate transformations are
separately defined for the first and second
scan head connector and serve the same purpose
as those of load_correction_file of the RTC4.
• RTC6 PCIe Boards do not support the coordinate
transformations (collectively for both scan heads)
before Microstepping which is possible with the
RTC4.
The global coordinate transformations have a
slightly different effect than the coordinate
transformations above, see 3, 5 and 6 in
Chapter 7.3.6 ”Output Values to the Scan
System”, page 181.
