Properties

anchorX

val anchorX: Double? = null

Transform anchor point X, absent if no transform specified

anchorY

val anchorY: Double? = null

Transform anchor point Y, absent if no transform specified

anchorZ

val anchorZ: Double? = null

Transform anchor point Z, absent if no transform specified

backendNodeId

val backendNodeId: BackendNodeId? = null

The backend id for the node associated with this layer.

drawsContent

val drawsContent: Boolean

Indicates whether this layer hosts any content, rather than being used for transform/scrolling purposes only.

height

val height: Double

Layer height.

invisible

val invisible: Boolean? = null

Set if layer is not visible.

layerId

val layerId: LayerId

The unique id for this layer.

offsetX

val offsetX: Double

Offset from parent layer, X coordinate.

offsetY

val offsetY: Double

Offset from parent layer, Y coordinate.

paintCount

val paintCount: Int

Indicates how many time this layer has painted.

parentLayerId

val parentLayerId: LayerId? = null

The id of parent (not present for root).

scrollRects

val scrollRects: List<ScrollRect>? = null

Rectangles scrolling on main thread only.

stickyPositionConstraint

val stickyPositionConstraint: StickyPositionConstraint? = null

Sticky position constraint information

transform

val transform: List<Double>? = null

Transformation matrix for layer, default is identity matrix

width

val width: Double

Layer width.
