DiscreteRotation

Kotlin |Java

value class DiscreteRotation

Kotlin value class that represents fixed 0, 90, 180, 270 degree rotations with utility functions for adding and subtracting discrete rotations from each other.

A DiscreteRotation represents integer degrees in fixed 90 degree increments.

from

Added in 1.7.0-alpha02

fun from(degrees: Int): DiscreteRotation

Convert integer degrees to a DiscreteRotation

fromSurfaceRotation

Added in 1.7.0-alpha02

fun fromSurfaceRotation(surfaceRotation: Int): DiscreteRotation

Get a DiscreteRotation from Surface rotation values.

Rotation values are relative to the device's "natural" rotation, Surface.ROTATION_0.

round

Added in 1.7.0-alpha02

fun round(degrees: Float): DiscreteRotation

Round degrees to the nearest DiscreteRotation (0, 90, 180, 270).

Negative values are rounded to the nearest positive DiscreteRotation (e.g. -90 rounds to 270). Boundary values (e.g. 45.0) are rounded up to the nearest 90-degree increment (e.g. 45.0 rounds to 90).

round

Added in 1.7.0-alpha02

fun round(degrees: Int): DiscreteRotation

Round degrees to the nearest DiscreteRotation (0, 90, 180, 270).

Negative values are rounded to the nearest positive DiscreteRotation (e.g. -90 rounds to 270). Boundary values (e.g. 45) are rounded up to the nearest 90-degree increment (e.g. 45 rounds to 90).
