List Command
para_mark_rel
Function moves the laser focus at marking speed 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
set_vector_control to the specified value.
Call
para_mark_rel( dX, dY, P )
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 set_vector_control (
Ctrl
parameter),
identical with set_vector_control (
Value
parameter)
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
para_mark_abs (see the comments there).
•
P
will not be treated on a relative basis.

5 new command
In RTC
®
4 compatibility mode, the RTC
®
5 multiplies the specified coordinate values by 16
(the permissible range of values is correspondingly reduced).
The parameter
P
does not have a RTC
®
4 compatibility mode. The original RTC
®
5 units
must be used.
