Constructors​
constructor​
Parameters
OverwritesRect.constructorProperties​
absolutePosition​
readonly public absolutePosition: SimpleVector2SignalImg
A helper signal for operating on the position in world space.
Retrieving the position using this signal returns the position in world space. Similarly, setting the position using this signal transforms the new value to local space.
If the new value is a function, the position of this node will be continuously updated to always match the position returned by the function. This can be useful to "pin" the node in a specific place or to make it follow another node's position.
Unlike position, this signal is not compound - it doesn't contain
separate signals for the x and y components.
Rect.absolutePositionabsoluteRotation​
readonly public absoluteRotation: SimpleSignalnumberImg
A helper signal for operating on the rotation in world space.
Retrieving the rotation using this signal returns the rotation in world space. Similarly, setting the rotation using this signal transforms the new value to local space.
If the new value is a function, the rotation of this node will be continuously updated to always match the rotation returned by the function.
Inherited fromRect.absoluteRotationabsoluteScale​
readonly public absoluteScale: SimpleVector2SignalImg
A helper signal for operating on the scale in world space.
Retrieving the scale using this signal returns the scale in world space. Similarly, setting the scale using this signal transforms the new value to local space.
If the new value is a function, the scale of this node will be continuously updated to always match the position returned by the function.
Unlike scale, this signal is not compound - it doesn't contain
separate signals for the x and y components.

readonly public alignItems: SimpleSignalFlexItemsImg
Rect.alignItemsalignSelf​
readonly public alignSelf: SimpleSignalFlexItemsImg
Rect.alignSelfalpha​
readonly public alpha: SimpleSignalnumberImg

Inherited fromRect.bottomRightcache​
readonly public cache: SimpleSignalbooleanImg
Rect.cachecachePadding​
readonly public cachePadding: SpacingSignalImg
Controls the padding of the cached canvas used by this node.
By default, the size of the cache is determined based on the bounding box
of the node and its children. That includes effects such as stroke or
shadow. This property can be used to expand the cache area further.
Usually used to account for custom effects created by shaders.
Rect.cachePaddingchildren​
readonly public children: SignalComponentChildrenNode[]ImgSignalContextComponentChildrenNode[]Img
Rect.childrenclip​
readonly public clip: SimpleSignalbooleanImg
Rect.clipclosed​

Inherited fromRect.closedcomposite​
readonly public composite: SimpleSignalbooleanImg
Rect.compositecompositeOperation​
readonly public compositeOperation: SimpleSignalGlobalCompositeOperationImg
Rect.compositeOperationcornerSharpness​
readonly public cornerSharpness: SimpleSignalnumberImg
Controls the sharpness of smoothCorners.
This property only affects the way rounded corners are drawn. To control
the corner radius use the radius property.
Requires smoothCorners to be enabled to have any effect.
By default, corner sharpness is set to 0.6 which represents a smooth,
circle-like rounding. At 0 the edges are squared off.
Examples
Inherited fromRect.cornerSharpnesscreationStack​
readonly public creationStack?: string
Rect.creationStackdirection​
readonly public direction: SimpleSignalFlexDirectionImg
Rect.directionelement​
public element: HTMLElement
Rect.elementend​
readonly public end: SimpleSignalnumberImg
A percentage from the start after which the curve should be clipped.
The portion of the curve that comes after the given percentage will be made invisible.
This property is usefully for animating the curve appearing on the screen.
The value of 0 means the very start of the curve (accounting for the
startOffset) while 1 means the very end (accounting for the
endOffset).
Rect.endendArrow​
readonly public endArrow: SimpleSignalbooleanImg
Whether to display an arrow at the end of the visible curve.
Use arrowSize to control the size of the arrow.
Rect.endArrowendOffset​
readonly public endOffset: SimpleSignalnumberImg
The offset in pixels from the end of the curve.
This property lets you specify where along the defined curve the actual
visible portion ends. For example, setting it to 20 will make the last
20 pixels of the curve invisible.
This property is useful for trimming the curve using a fixed distance.
If you want to animate the curve appearing on the screen, use end
instead.

If the offset has not been changed, this will be the same as the
position.
When retrieved, it will return the position of the center in the parent space.
Inherited fromRect.middleminHeight​
readonly public minHeight: SimpleSignalLengthLimitImg
Rect.minHeightminWidth​
readonly public minWidth: SimpleSignalLengthLimitImg
Rect.minWidthoffset​
readonly public offset: Vector2SignalImgVector2SignalContextImg
Represents the offset of this node's origin.
By default, the origin of a node is located at its center. The origin serves as the pivot point when rotating and scaling a node, but it doesn't affect the placement of its children.
The value is relative to the size of this node. A value of 1 means as far
to the right/bottom as possible. Here are a few examples of offsets:
[-1, -1]- top left corner[1, -1]- top right corner[0, 1]- bottom edge[-1, 1]- bottom left corner
Rect.offsetopacity​
readonly public opacity: SimpleSignalnumberImg
Represents the opacity of this node in the range 0-1.
The value is clamped to the range 0-1.

Examples
Inherited fromRect.positionproperties​
readonly public properties: RecordstringPropertyMetadataany = ...
Rect.propertiesradius​
readonly public radius: SpacingSignalImg
Rounds the corners of this rectangle.
The value represents the radius of the quarter circle that is used to round the corners. If the value is a number, the same radius is used for all corners. Passing an array of two to four numbers will set individual radii for each corner. Individual radii correspond to different corners depending on the number of values passed:
// top-left-and-bottom-right | top-right-and-bottom-left
[10, 30]
// top-left | top-right-and-bottom-left | bottom-right
[10, 20, 30]
// top-left | top-right | bottom-right | bottom-left
[10, 20, 30, 40]

Rect.shadowColorshadowOffset​
readonly public shadowOffset: Vector2SignalImgVector2SignalContextImg
Rect.shadowOffsetshrink​
readonly public shrink: SimpleSignalnumberImg
Rect.shrinksize​
readonly public size: Vector2LengthSignalImg
Represents the size of this node.
A size is a two-dimensional vector, where x represents the width, and y
represents the height.
The value of both x and y is of type Length which is
either:
number- the desired length in pixels${number}%- a string with the desired length in percents, for example'50%'null- an automatic length
When retrieving the size, all units are converted to pixels, using the
current state of the layout. For example, retrieving the width set to
'50%', while the parent has a width of 200px will result in the number
100 being returned.
When the node is not part of the layout, setting its size using percents refers to the size of the entire scene.
Examples
Inherited fromRect.sizeskew​
readonly public skew: Vector2SignalImgVector2SignalContextImg
Represents the skew of this node in local space of its parent.
Examples
Inherited fromRect.skewsmoothCorners​
readonly public smoothCorners: SimpleSignalbooleanImg

This property only affects the way rounded corners are drawn. To control
the corner radius use the radius property.
When enabled, rounded corners are drawn continuously using Bézier curves
rather than quarter circles. The sharpness of the curve can be controlled
with cornerSharpness.
You can read more about corner smoothing in this article by Nick Lawrence.

startOffset) while 1 means the very end (accounting for the
endOffset).

visible portion starts. For example, setting it to 20 will make the first
20 pixels of the curve invisible.
This property is useful for trimming the curve using a fixed distance.
If you want to animate the curve appearing on the screen, use start
instead.

Inherited fromRect.reparentrestore​
public restore(): void
public restoreduration: numbertiming?: TimingFunction: ThreadGenerator
Restore the node to its last saved state.
This method can be used together with the save method to restore a

Parameters
duration: number = 1
Rect.ripplesave​

node's current state and later restore it. It is possible to store more
than one state by calling save method multiple times.
Rect.savesnapshotClone​

Unlike clone, a snapshot clone calculates any reactive properties
at the moment of cloning and passes the raw values to the copy.
Parameters
customProps: NodeState = {}Properties to override.
Rect.snapshotClonetoPromise​
