Parameters

xform

RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.

points

Collection of LeadPoint objects. The points in the array must be in the order in which the vertices of the polygon are connected. To create the line that closes the polygon, the last point in the array is connected to the first point of the array.

tension

A value that specifies the amount that the curve bends between control points. Values greater than 1 produce unpredictable results.

fillMode

Indicates how to handle complex crossing lines.

Value	Meaning
LeadFillMode.Winding	All pixels that are inside the resulting exterior lines are in the region.
LeadFillMode.Alternate	The region includes the area between odd-numbered and even-numbered polygon sides on each scan line.
