class ZoomGestureDetector.ZoomEvent.Move : ZoomGestureDetector.ZoomEvent

kotlin.Any
↳	androidx.camera.viewfinder.core.ZoomGestureDetector.ZoomEvent
	↳	androidx.camera.viewfinder.core.ZoomGestureDetector.ZoomEvent.Move

The moving events of a gesture in progress. Reported by pointer motion.

Summary

Public constructors
`Move( eventTime: @IntRange(from = 0) Long, focusX: @Px @IntRange(from = 0) Int, focusY: @Px @IntRange(from = 0) Int, incrementalScaleFactor: @FloatRange(from = 0.0, fromInclusive = false) Float )`

Public properties
`Float`	`incrementalScaleFactor` The scaling factor from the previous zoom event to the current event.

Inherited properties

From androidx.camera.viewfinder.core.ZoomGestureDetector.ZoomEvent

`Long`	`eventTime` The event time in milliseconds of the current event being processed, in `SystemClock.uptimeMillis` time base.
`Int`	`focusX` The X coordinate of the current gesture's focal point in pixels.
`Int`	`focusY` The Y coordinate of the current gesture's focal point in pixels.

Public constructors

Move

Added in 1.4.0-alpha11

Move(
    eventTime: @IntRange(from = 0) Long,
    focusX: @Px @IntRange(from = 0) Int,
    focusY: @Px @IntRange(from = 0) Int,
    incrementalScaleFactor: @FloatRange(from = 0.0, fromInclusive = false) Float
)

Parameters
`eventTime: @IntRange(from = 0) Long`	The event time in milliseconds of the current event being processed, in `SystemClock.uptimeMillis` time base.
`focusX: @Px @IntRange(from = 0) Int`	The X coordinate of the current gesture's focal point in pixels.
`focusY: @Px @IntRange(from = 0) Int`	The Y coordinate of the current gesture's focal point in pixels.
`incrementalScaleFactor: @FloatRange(from = 0.0, fromInclusive = false) Float`	The scaling factor from the previous zoom event to the current event. The value will be less than `1.0` when zooming out (larger FOV) and will be larger than `1.0` when zooming in (narrower FOV).

Public properties

incrementalScaleFactor

Added in 1.4.0-alpha11

val incrementalScaleFactor: Float

The scaling factor from the previous zoom event to the current event. The value will be less than 1.0 when zooming out (larger FOV) and will be larger than 1.0 when zooming in (narrower FOV).
