Zero

val ZeroRect

A rectangle with left, top, right, and bottom edges all at zero.

Public constructors

Rect

Rect(left: Float, top: Float, right: Float, bottom: Float)

Public functions

contains

operator fun contains(offset: Offset): Boolean

Whether the point specified by the given offset (which is assumed to be relative to the origin) lies between the left and right and the top and bottom edges of this rectangle.

Rectangles include their top and left edges but exclude their bottom and right edges.

deflate

fun deflate(delta: Float): Rect

Returns a new rectangle with edges moved inwards by the given delta.

inflate

fun inflate(delta: Float): Rect

Returns a new rectangle with edges moved outwards by the given delta.

intersect

fun intersect(other: Rect): Rect

Returns a new rectangle that is the intersection of the given rectangle and this rectangle. The two rectangles must overlap for this to be meaningful. If the two rectangles do not overlap, then the resulting Rect will have a negative width or height.

intersect

fun intersect(
    otherLeft: Float,
    otherTop: Float,
    otherRight: Float,
    otherBottom: Float
): Rect

Returns a new rectangle that is the intersection of the given rectangle and this rectangle. The two rectangles must overlap for this to be meaningful. If the two rectangles do not overlap, then the resulting Rect will have a negative width or height.

overlaps

fun overlaps(other: Rect): Boolean

Whether other has a nonzero area of overlap with this rectangle.

toString

open fun toString(): String

translate

fun translate(offset: Offset): Rect

Returns a new rectangle translated by the given offset.

To translate a rectangle by separate x and y components rather than by an Offset, consider translate.

translate

fun translate(translateX: Float, translateY: Float): Rect

Returns a new rectangle with translateX added to the x components and translateY added to the y components.
