Functions

contains

open operator override fun contains(point: Point): Boolean

Uses winding-number approach https://en.wikipedia.org/wiki/Point_in_polygon

open operator override fun contains(rectangle: Rectangle): Boolean

equals

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

hashCode

open override fun hashCode(): Int

intersects

open infix override fun intersects(rectangle: Rectangle): Boolean

Checks whether the Shape intersects a rectangle.

map

fun ConvexPolygon.map(transform: (Point) -> Point): ConvexPolygon

Create a new ConvexPolygon with each point transformed by transform.

reversed

fun ConvexPolygon.reversed(): ConvexPolygon

Create a new ConvexPolygon with the same points, but in reversed order.

rounded

fun Polygon.rounded(config: (index: Int, Point) -> Double): Path

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.

toPath

fun Polygon.toPath(): Path

Converts a Polygon to a Path.
