Normal para_mark_rel
List Command
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
Call
para_mark_rel( dX, dY, P )
Parameters
dX, dY
P
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
• P will not be treated on a relative basis.

The parameter P does not have a RTC

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]

table.
