Command
mark_rel
Function Moves the laser focus at mark speed along a 2D vector from the current position to the
specified position (relative coordinate values) within a 2D Image Field.
Call mark_rel( dX, dY )
Parameters dX Relative x coordinate of the mark vector end point. In bits.
As a signed 32-bit value.
Allowed value range: [–268,435,456…+268,435,455].
Out-of-range values are clipped to the boundary values.
The complete value range is only usable as a virtual Image Field for example,
for (enabled) Processing-on-the-fly applications.
dY Like dX (analogously).
Comments • The coordinates for the mark vector end point are to be supplied as relative coordinates
with respect to the current position. Otherwise, mark_rel is identical to mark_abs (see
comments there).
RTC4RTC6 Unchanged functionality. In addition: increased value range.
In RTC4 Compatibility Mode, the RTC6 multiplies the values specified for dX and dY by 16.
The allowed value range decreases accordingly.
RTC5RTC6 Unchanged functionality. In addition: increased value range.
Version info Available as of DLL 600, OUT 600, RBF 600.
