Class: InkPath2D

PathBuilding.InkPath2D(…polygons)

Represents complex shape - collection of polygons.

Constructor

new InkPath2D(…polygons)

Parameters:

Name	Type	Attributes	Description
polygons	VarArgs.<PathBuilding.Polygon>	<repeatable>

Properties:

Name	Type	Attributes	Default	Description
bounds	Common.Rect			Ink path bounds
segment	boolean	<optional>	false	It is true when InkPath2D is result from addition or prediction

Since:

• version 3.0

Extends

• PathBuilding.PolygonArray

Methods

clone() → PathBuilding.PolygonArray

Clone instance

Overrides:

• PathBuilding.PolygonArray#clone

Returns:

PolygonArray instance

Type

PathBuilding.PolygonArray

intersects(path) → PathBuilding.InkPath2D.IntersectionContext

Check are 2 ink paths have common part

Parameters:

Name	Type	Description
path	PathBuilding.InkPath2D	Intersect with path

Returns:

Intersection context, when have intersection

Type

PathBuilding.InkPath2D.IntersectionContext

push(…polygons)

Parameters:

Name	Type	Attributes	Description
polygons	VarArgs.<PathBuilding.Polygon>	<repeatable>

Overrides:

• PathBuilding.PolygonArray#push

toJSON() → {JSON}

Serialize to JSON

Overrides:

• PathBuilding.PolygonArray#toJSON

Returns:

Ink path data

Type

JSON

transform(matrix) → PathBuilding.PolygonArray

Transform all polygons

Parameters:

Name	Type	Description
matrix	Common.Matrix	Transform matrix

Overrides:

• PathBuilding.PolygonArray#transform

Returns:

poly Transformed polygon

Type

PathBuilding.PolygonArray

transformSelf(matrix)

Self transform all polygons

Parameters:

Name	Type	Description
matrix	Common.Matrix	Transform matrix

Overrides:

• PathBuilding.PolygonArray#transformSelf

union(cleanDeltaopt) → PathBuilding.Polygon

Removes self-intersections from the supplied polygon (by performing a boolean union operation using the nominated PolyFillType).Polygons with non-contiguous duplicate vertices (ie 'touching') will be split into two polygons.

Parameters:

Name	Type	Attributes	Default	Description
cleanDelta	float	<optional>	0.1	Uses Radial Reduction algorithm, which merges sequential vertices, if they are at or under certain distance of each other, merge also collinear vertices

See:

• http://www.angusj.com/delphi/clipper/documentation/Docs/Units/ClipperLib/Functions/SimplifyPolygon.htm

Returns:

Merged polygon with holes if they are available

Type

PathBuilding.Polygon

(static) fromJSON(data) → PathBuilding.InkPath2D

Deserialize from JSON

Parameters:

Name	Type	Description
data	JSON	Ink path data

Returns:

InkPath2D instance

Type

PathBuilding.InkPath2D

Type Definitions

IntersectionContext

Polygons which intersects

Properties:

Name	Type	Description
poly1	PathBuilding.Polygon
poly2	PathBuilding.Polygon
