- From:
- http://www.w3.org/TR/SVG/implnote.html#ArcConversionEndpointToCenter
- A point (x,y) on the arc can be found by:
-
- {x,y} = {cx,cy} + {cosF,-sinF,sinF,cosF} x {rxcosT,rysinT}
-
- where
- {cx,cy} is the center of the ellipse
- F is the rotation angle of the X axis of the ellipse from the true X axis
- T is the rotation angle around the ellipse
- {,,,} is the rotation matrix
- rx,ry are the radii of the ellipse's axes
-
- For SVG parameterization need two points.
- Arbitrarily we can use T=0 and T=pi
- Since the sweep is 180 the flags are always 0:
-
- F is in RADIANS, but the SVGEllipticalArc needs degrees!
