PolyLineMetafileCommandCreateArcs Method

Loops through the given range of points and tries to detect arcs. We start with the first three points and calculate an arc out of them. If the angle does not exceed maxPhi it is considered to be a valid arc, and the next point is checked if it lays on the same circle. This is to be considered as yes if its distance from the arc's center does not differ from the arc's radius more than delta and if the angle between the last point and the point is not larger then maxPhi - and so on with the next point. If an arc is detected it is put in the resulting list of BaseMetafileCommands, if not the points are put into the list as lines.

public List<BaseMetafileCommand> CreateArcs(
	int startIdx = -1,
	int numberOfPoints = 0,
	double delta = 100,
	double maxPhi = 0.3
