RectF

RectF

RectF()

Create a new empty RectF. All coordinates are initialized to 0.

RectF

RectF(r: Rect?)

RectF

RectF(r: RectF?)

Create a new rectangle, initialized with the values in the specified rectangle (which is left unmodified).

RectF

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

Create a new rectangle with the specified coordinates. Note: no range checking is performed, so the caller must ensure that left <= right and top <= bottom.

centerX

fun centerX(): Float

centerY

fun centerY(): Float

contains

open fun contains(r: RectF): Boolean

Returns true iff the specified rectangle r is inside or equal to this rectangle. An empty rectangle never contains another rectangle.

contains

open fun contains(
    x: Float, 
    y: Float
): Boolean

Returns true if (x,y) is inside the rectangle. The left and top are considered to be inside, while the right and bottom are not. This means that for a x,y to be contained: left <= x < right and top <= y < bottom. An empty rectangle never contains any point.

contains

open fun contains(
    left: Float, 
    top: Float, 
    right: Float, 
    bottom: Float
): Boolean

Returns true iff the 4 specified sides of a rectangle are inside or equal to this rectangle. i.e. is this rectangle a superset of the specified rectangle. An empty rectangle never contains another rectangle.

describeContents

open fun describeContents(): Int

Parcelable interface methods

equals

open fun equals(other: Any?): Boolean

hashCode

open fun hashCode(): Int

height

fun height(): Float

inset

open fun inset(
    dx: Float, 
    dy: Float
): Unit

Inset the rectangle by (dx,dy). If dx is positive, then the sides are moved inwards, making the rectangle narrower. If dx is negative, then the sides are moved outwards, making the rectangle wider. The same holds true for dy and the top and bottom.

intersect

open fun intersect(r: RectF): Boolean

If the specified rectangle intersects this rectangle, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle. No check is performed to see if either rectangle is empty. To just test for intersection, use intersects()

intersect

open fun intersect(
    left: Float, 
    top: Float, 
    right: Float, 
    bottom: Float
): Boolean

If the rectangle specified by left,top,right,bottom intersects this rectangle, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle. No check is performed to see if either rectangle is empty. Note: To just test for intersection, use intersects()

intersects

open fun intersects(
    left: Float, 
    top: Float, 
    right: Float, 
    bottom: Float
): Boolean

Returns true if this rectangle intersects the specified rectangle. In no event is this rectangle modified. No check is performed to see if either rectangle is empty. To record the intersection, use intersect() or setIntersect().

intersects

open static fun intersects(
    a: RectF, 
    b: RectF
): Boolean

Returns true iff the two specified rectangles intersect. In no event are either of the rectangles modified. To record the intersection, use intersect() or setIntersect().

isEmpty

fun isEmpty(): Boolean

Returns true if the rectangle is empty (left >= right or top >= bottom)

offset

open fun offset(
    dx: Float, 
    dy: Float
): Unit

Offset the rectangle by adding dx to its left and right coordinates, and adding dy to its top and bottom coordinates.

offsetTo

open fun offsetTo(
    newLeft: Float, 
    newTop: Float
): Unit

Offset the rectangle to a specific (left, top) position, keeping its width and height the same.

readFromParcel

open fun readFromParcel(in: Parcel): Unit

Set the rectangle's coordinates from the data stored in the specified parcel. To write a rectangle to a parcel, call writeToParcel().

round

open fun round(dst: Rect): Unit

Set the dst integer Rect by rounding this rectangle's coordinates to their nearest integer values.

roundOut

open fun roundOut(dst: Rect): Unit

Set the dst integer Rect by rounding "out" this rectangle, choosing the floor of top and left, and the ceiling of right and bottom.

set

open fun set(src: Rect): Unit

Copy the coordinates from src into this rectangle.

set

open fun set(src: RectF): Unit

Copy the coordinates from src into this rectangle.

set

open fun set(
    left: Float, 
    top: Float, 
    right: Float, 
    bottom: Float
): Unit

Set the rectangle's coordinates to the specified values. Note: no range checking is performed, so it is up to the caller to ensure that left <= right and top <= bottom.

setEmpty

open fun setEmpty(): Unit

Set the rectangle to (0,0,0,0)

setIntersect

open fun setIntersect(
    a: RectF, 
    b: RectF
): Boolean

If rectangles a and b intersect, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle. No check is performed to see if either rectangle is empty. To just test for intersection, use intersects()

sort

open fun sort(): Unit

Swap top/bottom or left/right if there are flipped (i.e. left > right and/or top > bottom). This can be called if the edges are computed separately, and may have crossed over each other. If the edges are already correct (i.e. left <= right and top <= bottom) then nothing is done.

toShortString

open fun toShortString(): String

Return a string representation of the rectangle in a compact form.

toString

open fun toString(): String

union

open fun union(r: RectF): Unit

Update this Rect to enclose itself and the specified rectangle. If the specified rectangle is empty, nothing is done. If this rectangle is empty it is set to the specified rectangle.

union

open fun union(
    x: Float, 
    y: Float
): Unit

Update this Rect to enclose itself and the [x,y] coordinate. There is no check to see that this rectangle is non-empty.

union

open fun union(
    left: Float, 
    top: Float, 
    right: Float, 
    bottom: Float
): Unit

Update this Rect to enclose itself and the specified rectangle. If the specified rectangle is empty, nothing is done. If this rectangle is empty it is set to the specified rectangle.

width

fun width(): Float

writeToParcel

open fun writeToParcel(
    out: Parcel, 
    flags: Int
): Unit

Write this rectangle to the specified parcel. To restore a rectangle from a parcel, use readFromParcel()
