Undelayed set_ellipse
Short
List Command
Function defines the shape of an elliptical arc that can subsequently be marked via
mark_ellipse_abs
Call
set_ellipse( a, b, Phi0, Phi )
Parameters
a, b
Phi0
Phi
Comments • Specify the to-be-marked elliptical arc's position and orientation in the two-dimen-
sional image field via
individual parameters, also see
• For a < 1 or/and b < 1, set_ellipse is replaced with a
code: RTC5_PARAM_ERROR).

In RTC 4 compatibility mode, the RTC
elliptical half-axes by 16 (the permissible range of values is correspondingly reduced to
[1 ... 524287]).
Version info • Available beginning with version DLL 518, OUT 517, RBF 515
• For older RTC
the command is neither executed nor replaced by
RTC5_TYPE_REJECTED).

Lengths of the elliptical half-axes in bits as unsigned 32-bit values;
allowed range: [1 ... 8388607];
out-of-range positive values will be edge-clipped.
Beginning phase angle in ° (the arc starting point's position relative to the end
point of half-axis a) as a 64-bit IEEE floating point value
(positive angle values correspond to clockwise angles);
Phi0 gets normalized to the value range [0...<360°].
arc angle in ° (to-be-marked ellipse section) as a 64-bit IEEE floating point
value (positive angle values correspond to clockwise angles);
allowed range: [–3600.0° ... +3600.0°] (±10 full ellipses);
an out-of-range value will be edge-clipped.
