    Public Properties
     NameDescription
    Public PropertyAreaGets the area of the polygon.  
    Public PropertyAreaSignedGets the signed area of the polygon.  
    Public PropertyBarycenterGets the barycenter of the polygon.

    Public Methods
     NameDescription
    Public MethodAddToGraphicsPathAppends the primitive to the specified graphics path  
    Public MethodAreaIntersectsWithDetermines whether this polygon area intersects with the specified rectangle area.  
    Public MethodContainsOverloaded. Determines whether the primitive interior contains the specified point  
    Public MethodContainsOnOutlineOverloaded. Determines whether the outline of the polygon contains the specified point  
    Public Methodstatic (Shared in Visual Basic)FromRectCreates a polygon from the given rectangle.  
    Public MethodGetConvexHullComputes the convex hull of the polygon using the Graham Scan algorithm. Returns the points forming the convex hull in counterclockwise order.  
    Public MethodGetLongestLineOverloaded. Gets the longest horizontal inner line in the polygon.  
    Public MethodGetMinimumEnclosingCircleComputes the minimal enclosing circle (a.k.a the bomb problem) using the Welzl's algorithm.  
    Public MethodIntersectsWithOverloaded. Determines whether this polygon intersects with the specified line.  
    Public MethodIntersectWithOverloaded. Checks if this polygon intersect with the given line segment and returns the intersection points if it does.  
    Public MethodInvalidateCacheInvalidates any cached information about the polygon.  
    Public MethodOutlineIntersectsWith/Determines whether this polygon outline intersects with the specified rectangle.  
    Public MethodScanlineCrossingCountsObtains the number of clockwise and counterwise crossings of a scanline with the polygon segments.  
    Public MethodSimplifyReturns a simplified version of this polygon using an improved version Douglas and Peucker algorithm (uses path hulls) which improves the worst case running time from O(n^2) to O(n * log2(n)). Topology is preserved.  
    Public MethodTranslateOverloaded. Translates the primitive with the specified amounts
