Polygon

abstract class Polygon : Shape(source)

A Shape defined by a set of line segments that connect to enclose a region.

Constructors

constructor()

open override val area: Double

Gives the smallest Rectangle that fully contains this Polygon.

abstract val empty: Boolean

abstract val points: List<Point>

Points representing the vertices

abstract operator fun contains(point: Point): Boolean

Checks whether the Shape contains a given point.

abstract operator fun contains(rectangle: Rectangle): Boolean

Checks whether the Shape contains a given rectangle.

open operator override fun equals(other: Any?): Boolean

open override fun hashCode(): Int

abstract infix fun intersects(rectangle: Rectangle): Boolean

Checks whether the Shape intersects a rectangle.

fun Polygon.rounded(radius: Double, filter: (index: Int, Point) -> Boolean = { _,_ -> true }): Path

Creates a rounded shape from a Polygon. The resulting shape is essentially a polygon with the vertices rounded using a semicircular curve.

Converts a Polygon to a Path.
