unpublished struct EllipticalArc
Usage Restrictions
not published
Description
This structure specifies an arbitrary elliptical arc.

This structure contains all parameters necessary to specify arbitrary elliptical arcs. The parameters are modelled closely after the SVG specification.

As with the parameters below, there are mostly four different ellipses arcs (two different ellipses, on which four different arcs connect start and end point) which satisfy the given set of constrains. Thus, there are two flags indicating which one of those ellipses should be taken.

OOo 2.0

Elements' Summary
StartPosition Start point of the arc. 
EndPosition End point of the arc. 
RadiusX Main radius in x direction of the ellipse this arc is part of. 
RadiusY Main radius in y direction of the ellipse this arc is part of. 
XAxisRotation Rotation angle of the x axis of the ellipse relative to the x axis of the reference coordinate system.  
IsLargeArc If true, and there's a choice, take the longer one of two arcs connecting start and end point.  
IsClockwiseSweep If true, and there's a choice, take the arc that goes clock-wise from start to end point.
