Origo of ellipse in EllipticalArc

[Anders]

Hi!

I need to calculate the origo of the ellipse that an EllipticalArc is drawn
from.

From the EllipticalArcTo geometry section i get.

x1, y1 - coordinates for starting point
x2, y2 - coordinates for control point
x3, y3 - coordinate for vertex point
alpha - angle of the ellipses local coordinate system to the global
coordinate system
D - ratio between major and minor axis

From these given values I need to calculate the global origo of the
EllipticalArcs ellipse.

Me and a guy here where I work was successful in solving it using Maple...

Thanks anyway!
