Public Constructors
public InterpolatingScaleType (ScalingUtils.ScaleType scaleTypeFrom, ScalingUtils.ScaleType scaleTypeTo, Rect boundsFrom, Rect boundsTo, PointF focusPointFrom, PointF focusPointTo)
public InterpolatingScaleType (ScalingUtils.ScaleType scaleTypeFrom, ScalingUtils.ScaleType scaleTypeTo, Rect boundsFrom, Rect boundsTo)
public InterpolatingScaleType (ScalingUtils.ScaleType scaleTypeFrom, ScalingUtils.ScaleType scaleTypeTo)
Public Methods
public Rect getBoundsFrom ()
public Rect getBoundsTo ()
public PointF getFocusPointFrom ()
public PointF getFocusPointTo ()
public Object getState ()
Returns the internal state. The returned object must be immutable!
The returned state may be used for caching the result of ScaleType.getTransform.
If null state is returned, the result will not be cached. If non-null state is returned, the
old transformation may be used if produced with an equal state.
public Matrix getTransform (Matrix transform, Rect parentBounds, int childWidth, int childHeight, float focusX, float focusY)
Gets transformation matrix based on the scale type.
Parameters
| transform | out matrix to store result |
|---|---|
| parentBounds | parent bounds |
| childWidth | child width |
| childHeight | child height |
| focusX | focus point x coordinate, relative [0...1] |
| focusY | focus point y coordinate, relative [0...1] |
Returns
- same reference to the out matrix for convenience
public float getValue ()
Gets the interpolating value.
public void setValue (float value)
Sets the interpolating value.
Value of 0.0 will produce the transform same as ScaleTypeFrom. Value of 1.0 will produce the transform same as ScaleTypeTo. Inbetween values will produce a transform that is a linear combination between the two.
