Constructor OffsetOptions

Initializes offset options.

public OffsetOptions(OffsetJoin join, double miterLimit = 10, double arcTolerance = 0)

join OffsetJoin: How the gap at a corner is closed.
miterLimit double: How far a Miter corner may reach from its vertex, as a multiple of the offset distance; beyond it the corner is cut off square at that distance. At least 1, and PositiveInfinity keeps every corner sharp. Ignored by the other joins.
arcTolerance double: The largest gap allowed between a Round corner and the true arc, in drawing units. Zero (the default) picks AutomaticArcToleranceRatio of the offset distance. Ignored by the other joins.

ArgumentOutOfRangeException: Thrown when the join is not a defined value, the miter limit is below 1 or not a number, or the arc tolerance is negative, infinite or not a number.
