draw_ellipse_moddraw_ellipse_modDrawEllipseModdraw_ellipse_modDrawEllipseModDrawEllipseMod returns the parameter for any orientated ellipse, which
has been created interactively by the user in the window.
The created ellipse is described by its center, its two half axes and the angle
between the first half axis and the horizontal coordinate axis.
To create an ellipse are expected the parameters RowInRowInRowInRowInRowInrowIn,
ColumnInColumnInColumnInColumnInColumnIncolumnIn,PhiInPhiInPhiInPhiInPhiInphiIn,Radius1InRadius1InRadius1InRadius1InRadius1Inradius1In,Radius2InRadius2InRadius2InRadius2InRadius2Inradius2In.
Keeping the button pressed determines the length (Radius1Radius1Radius1Radius1Radius1radius1)
and the orientation (PhiPhiPhiPhiPhiphi) of the first half axis.
In doing so a temporary default length for the second half axis is assumed, which may be
modified afterwards on demand.
After another mouse click in the center of the created ellipse you can move it.
A mouse click close to a vertex “grips” it to modify the length of the appropriate
half axis. You may modify the orientation only, if a vertex of the first half axis is
gripped.
Pressing the right mouse button terminates the procedure. On OS X
draw_ellipse_moddraw_ellipse_modDrawEllipseModdraw_ellipse_modDrawEllipseModDrawEllipseMod can also be terminated by pressing the escape key.
After terminating the procedure the ellipse is not visible in the window any longer.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Column index of the center.
Orientation of the bigger half axis in radians.
Column index of the center.
Orientation of the first half axis in radians.

draw_ellipse_moddraw_ellipse_modDrawEllipseModdraw_ellipse_modDrawEllipseModDrawEllipseMod returns 2 (H_MSG_TRUE), if the window is valid and the
needed drawing mode (see set_insertset_insertSetInsertset_insertSetInsertSetInsert) is available.
If necessary, an exception is raised.
