KonturEngine (Euclid.Kontur)

KonturEngine Type

Namespace: Euclid
Assembly: Euclid.Kontur.dll
Base Type: obj

Runs boolean operations on Kontur values. Holds all scratch buffers of the algorithm, so that repeated
 operations on one engine do not allocate anything but the result Polyline2Ds.
 Not thread safe, use one engine per thread.
 The tolerance is absolute, in the units of the coordinates: points closer than the tolerance are the same
 point, a point closer than the tolerance to a segment lies on it. See DESIGN.md section 2.

Constructors

Constructor	Description
`KonturEngine(tolerance)` Full Usage: `KonturEngine(tolerance)` Parameters: tolerance : `float` Returns: `KonturEngine`	tolerance : `float` Returns: `KonturEngine`

Instance members

Instance member	Description
`this.Execute` Full Usage: `this.Execute` Parameters: subject : `Kontur` - The subject Kontur. clip : `Kontur` - The clip Kontur. May be empty, then Union returns the subject simplified under its fill rule. op : `ClipType` - Union, Intersection, Difference (subject minus clip) or Xor. Returns: `Kontur` A simple Kontur with fill rule Positive: no self intersections, no overlaps, outer contours counter clockwise, holes clockwise. Input vertices of the result keep their exact coordinates.	Runs one boolean operation between a subject and a clip Kontur. The fill rule of each Kontur decides what is inside it, see the docs of FillRule. subject : `Kontur` The subject Kontur. clip : `Kontur` The clip Kontur. May be empty, then Union returns the subject simplified under its fill rule. op : `ClipType` Union, Intersection, Difference (subject minus clip) or Xor. Returns: `Kontur` A simple Kontur with fill rule Positive: no self intersections, no overlaps, outer contours counter clockwise, holes clockwise. Input vertices of the result keep their exact coordinates.
`this.Simplify` Full Usage: `this.Simplify` Parameters: shape : `Kontur` Returns: `Kontur`	Resolves the self intersections and overlaps of one Kontur under its fill rule. The same as a Union with an empty clip. shape : `Kontur` Returns: `Kontur`
`this.Tolerance` Full Usage: `this.Tolerance` Returns: `float`	The absolute tolerance of this engine. Returns: `float`
`this.UnionAll` Full Usage: `this.UnionAll` Parameters: shapes : `Kontur seq` Returns: `Kontur`	Union of any number of Kontur values, each under its own fill rule. Every Kontur is simplified on its own first, then all results are merged in one NonZero pass. shapes : `Kontur seq` Returns: `Kontur`

Static members

Static member	Description
`KonturEngine.DefaultTolerance` Full Usage: `KonturEngine.DefaultTolerance` Returns: `float`	The default absolute tolerance: 1e-6 Returns: `float`
