value
Int32

zoom value. The valid range is 0 to android.hardware.Camera.Parameters#getMaxZoom.

Attributes

Exceptions

if the zoom value is invalid.

if the method fails.

Remarks

Zooms to the requested value smoothly. The driver will notify OnZoomChangeListener of the zoom value and whether zoom is stopped at the time. For example, suppose the current zoom is 0 and startSmoothZoom is called with value 3. The Camera.OnZoomChangeListener#onZoomChange(int, boolean, Camera) method will be called three times with zoom values 1, 2, and 3. Applications can call #stopSmoothZoom to stop the zoom earlier. Applications should not call startSmoothZoom again or change the zoom value before zoom stops. If the supplied zoom value equals to the current zoom value, no zoom callback will be generated. This method is supported if android.hardware.Camera.Parameters#isSmoothZoomSupported returns true.
