Mark_Ellipse_Rel - Scanlab RTC6 PCIe Board Installation And Operation Manual

Normal List

mark_ellipse_rel

Command
Function Moves the laser focus at mark speed along an elliptical arc around the specified midpoint
(relative coordinate values) within a 2D
mark_ellipse_rel( dX, dY, Alpha )
Call
dX
Parameters
dY
Alpha
Comments • The coordinates for the ellipse midpoint are to be specified as relative coordinates with
respect to the current position. Otherwise, mark_ellipse_rel is identical to
mark_ellipse_abs
RTC4RTC6 New command.
In RTC4 Compatibility
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.

10 RTC6 Commands
Relative x coordinate of the ellipse midpoint. 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.
Like dX (analogously).
Angle between elliptical half-axis a (defined by set_ellipse) and the x axis (see
mark_ellipse_abs). In degrees.
As a 64-bit IEEE floating point value.
(see comments there).
Mode, the RTC6 multiplies the specified values for dX and dY by 16.
