Command
para_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. Simultaneously
varies the signal parameter selected by set_vector_control linearly to the specified value.
Call para_mark_rel( dX, dY, P )
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).
P End value of the signal parameter.
As an unsigned 32-bit value.
Allowed values: dependent on the selection made by set_vector_control
( Ctrl parameter), identical with set_vector_control ( Value parameter).
Comments • The coordinates for the mark vector end point are to be supplied as relative coordinates
with respect to the current position. Otherwise, para_mark_rel is identical to
para_mark_abs (see comments there).
• P is not treated on a relative basis.
• [*]para_mark[*] commands generally do not take Sky Writing into account.
RTC4RTC6 New command.
In RTC4 Compatibility Mode, the RTC6 multiplies the specified values for dX and dY by 16.
The allowed value range decreases accordingly. For the parameter P see para_jump_abs.
RTC5RTC6 Unchanged functionality.
For the parameter P , see para_jump_abs.
