GetVertexVisibility

Description

Returns the visibility of the specified vertex of the referenced object.

FUNCTION GetVertexVisibility(
				h       : HANDLE;
				vertnum : INTEGER): BOOLEAN;
def vs.GetVertexVisibility(h, vertnum):
    return BOOLEAN

Parameters

Name Type Description
h HANDLE Handle to the polygon or polyline
vertnum INTEGER Index of the vertex (zero-based).

Examples

		THEN closeShape := TRUE {so it will default to true the first time}
		ELSE closeShape := Str2Boo(GetElement(xmlID, 'PropertyLine/closeShape'));
	xmlID := ReleaseXML(xmlID);

	GetSymLoc(objHand, originPt.x, originPt.y);
	objectRotation := GetSymRot(objHand);
	Polyline2ARRAY(pathHandle, 179, .1", FALSE, FALSE, verts, vertCnt);
	ALLOCATE segs [1..vertCnt];
