public class HistoricalChange(
public val uptimeMillis: Long,
public val position: Offset,
public val scaleFactor: Float = 1f,
public val panOffset: Offset = Offset.Zero,
)Data structure for "historical" pointer moves.
Optional high-frequency pointer moves in between the last two dispatched events: can be used for extra accuracy when input rate exceeds framerate.
Parameters
| uptimeMillis | The time of the historical pointer event, in milliseconds. In between the current and previous pointer event times. |
| position | The Offset of the historical pointer event, relative to the containing element. |
| scaleFactor | A multiplicative scale factor indicating the amount of scale to perform as part of this pointer input change. A value of 1f indicates no scale, a value less than 1f indicates a scale down, commonly causing a zoom out, and a value greater than 1f indicates a scale up, commonly causing a zoom in. |
| panOffset | An Offset in pixel coordinates indicating an amount of scrolling. |
