Package-level declarations

Types

Identifies a coordinate space (e.g., viewport or zoomable image) that provides context to SpatialOffset values. The conversion between coordinate spaces is provided by a CoordinateSystem.

CoordinateSystem

interface CoordinateSystem

Represents a system that understands its coordinate spaces and how spatial offsets are interpreted and transformed across them.

SpatialOffset

@Immutable

class SpatialOffset(offset: Offset, val space: CoordinateSpace)

A 2D offset bound to a specific CoordinateSpace inside a CoordinateSystem.

SpatialRect

@Immutable

class SpatialRect

A 2D rectangle bound to a specific CoordinateSpace inside a CoordinateSystem.

Properties

isSpecified

@Stable

val SpatialOffset.isSpecified: Boolean

false when this is SpatialOffset.Unspecified.

@Stable

val SpatialRect.isSpecified: Boolean

false when this is SpatialRect.Unspecified.

isUnspecified

@Stable

val SpatialOffset.isUnspecified: Boolean

true when this is SpatialOffset.Unspecified.

@Stable

val SpatialRect.isUnspecified: Boolean

true when this is SpatialRect.Unspecified.

Functions

takeOrElse

inline fun SpatialOffset.takeOrElse(block: () -> SpatialOffset): SpatialOffset

If this Offset then this is returned, otherwise block is executed and its result is returned.
