Description

This function draws an elliptical arc.
A full ellipse is drawn if the start and end angles are the same. The path is not closed, stroked or filled so that it will be invisible as long it is not stroked, filled or both (see DynaPDF.ClosePath, DynaPDF.StokePath for further information).
The current point is connected with the start point of the ellipse and then updated to the end point of the ellipse.
The draw direction can be changed with the function DynaPDF.SetDrawDirection. The start and end angles are always measured counter clockwise independent of the drawing direction.
