List Command
timed_para_mark_rel
Function
moves the laser focus for the specified marking duration along a 2D vector from the
current position to the specified position (relative coordinate values) within a two-
dimensional image field and, simultaneously as well as linearly, changes the signal
parameter selected via
to the specified value.
Call
timed_mark_rel( dX, dY, P, T )
Parameters
dX, dY
relative coordinates of the mark vector end point in
bits
as signed 32-bit
values; allowed range: [–8388608 … 8388607] (out-of-range values will be
edge-clipped). The complete value range [–8388608 … 8388607] is only
usable as a virtual image field e.g. for (enabled) Processing-on-the-fly
applications. The current coordinates will be clipped to [–524288 … 524287]
(real image field size) during runtime directly prior to use of the correction
table.
P
End value of the signal parameter as an unsigned 32-bit value; allowed range:
dependent on the selection made via
Ctrl
parameter),
identical with
(
Value
parameter)
T
duration of the complete mark vector in
microseconds
(as a 64-bit IEEE
floating point value); allowed range: [0 … 167772160]; the parameter will be
rounded to an integer-multiple of 10; out-of-range values will be clipped.

Comments
• The coordinates for the mark vector’s end point are to be supplied as relative coordi-
nates with respect to the current position. Otherwise, the command is identical to
(see the comments there, exception:
T
< 5, see above).
