The CPLY type exposes the following members.

Methods

	Name	Description
	AddPolygon	Add a polygon to the polygon file.
	AddPolygonEx	Add a polygon to the polygon file.
	ChangeIPJ	Set the projection.
	Clear	Clear/remove all polygons from the PLY.
	Combine	Combines two PLY Object with another
	Copy	Copies one PLY Object to another
	Create	Creates a Polygon Object.
	CreateS	Create an PLY Object from a BF
	Dispose	Releases the unmanaged resources used by the CPLY and optionally releases the managed resources (Overrides CHANDLEDispose(Boolean).)
	Extent	Get the extent of the current polygon.
	GetIPJ	Get the projection.
	GetPolygon	Get a polygon from the PLY
	GetPolygonEx	Get a polygon from the PLY
	iClipArea	Clip a polygon to an area
	iClipLineInt	Clips a line in or out of the polygons for intersections (<define>GS_DOUBLE</define>). Intersections are returned as fiducials down the line stored in VV starting at the first point of the line. Examples: No intersection: <define>PLY_LINE_CLIP_OUTSIDE</define>, 0 intersections Starts outside, ends inside: <define>PLY_LINE_CLIP_OUTSIDE</define>, 1 intersection Starts outside, intersects then ends inside or outside: <define>PLY_LINE_CLIP_OUTSIDE</define>, 2 intersections Starts inside, ends inside : <define>PLY_LINE_CLIP_INSIDE</define>, 1 intersection (gives end-of-line) Starts inside, ends outside : <define>PLY_LINE_CLIP_INSIDE</define>, 1 intersection
	iClipPLY	Clip one polygon against another
	iClipPoint	Clips a point in or out of the polygon. Point is inside: <define>PLY_POINT_CLIP_INSIDE</define> Point is outside: <define>PLY_POINT_CLIP_OUTSIDE</define> An error occurred: <define>PLY_POINT_CLIP_ERROR</define>
	IGetDescription(String)	Get the PLY description string
	IGetDescription(String, Int32)	Get the PLY description string
	iNumPoly	Get the number of polygons.
	IsValid	Ensure a polygon is valid
	LoadTable	Loads Polygons from a Polygon file.
	rArea	Compute the Area of a polygon
	Rectangle	Creates a polygon from a rectangular area.
	Rotate	Rotate a polygon about a point.
	SaveTable	Save Polygons to a Polygon file.
	Serial	Serialize an PLY to a BF
	SetDescription	Set the PLY description string
	SetIPJ	Set the projection.
	Thin	Thin polygons to a desired resolution
