Member Function Documentation

Intersect()

array Geometry.Intersect	(	array	subjects,
		array	clips,
		GeoBooleanOp	booleanOp = < ref GeoBooleanOp_Intersection >,
		GeoFillRule	fillRule = < ref GeoFillRule_EvenOdd > )

Intersects a 2D polygon.

Parameters

subjects	Array of subject polygons.
clips	Array of clip polygons.
booleanOp	The boolean operation.
fillRule	The fill rule.

Returns

Returns an array containing a list of intersected polygons, or null if the polygon could not be intersected.

IsLineIntersectingPolygon()

boolean Geometry.IsLineIntersectingPolygon	(	array	polygon,
		decimal	x1,
		decimal	y1,
		decimal	x2,
		decimal	y2 )

Checks if a line segment is intersecting a polygon.

Parameters

polygon	The polygon to check.
x1	The starting X of the segment.
y1	The starting Y of the segment.
x2	The ending X of the segment.
y2	The ending Y of the segment.

Returns

Returns whether the line segment is intersecting the polygon.

IsPointInsidePolygon()

boolean Geometry.IsPointInsidePolygon	(	array	polygon,
		decimal	pointX,
		decimal	pointY )

Checks if a point is inside a polygon.

Parameters

polygon	The polygon.
pointX	The X of the point.
pointY	The Y of the point.

Returns

Returns whether the point is inside.

Triangulate()

array Geometry.Triangulate	(	array	polygon,
		array	holes )

Triangulates a 2D polygon.

Parameters

polygon	Array of vertices that compromise the polygon to triangulate.
holes	Array of polygons that compromise the holes to be made in the resulting shape.

Returns

Returns an array containing a list of triangles, or null if the polygon could not be triangulated.
