Class StateController

java.lang.Object

com.alexvasilkov.gestures.StateController

public class StateController
extends java.lang.Object

Helper class that holds reference to Settings object and controls some aspects of view State, such as movement bounds restrictions (see getMovementArea(State, RectF)) and dynamic min / max zoom levels (see getMinZoom(State) and getMaxZoom(State)).

Method Detail

getMinZoom

public float getMinZoom(State state)

Returns:

Min zoom level as it's used by state controller.

getMaxZoom

public float getMaxZoom(State state)

Returns:

Max zoom level as it's used by state controller. Note, that it may be different from Settings.getMaxZoom().

getMovementArea

public void getMovementArea(State state,
                            android.graphics.RectF out)

Calculates area in which State.getX() & State.getY() values can change. Note, that this is different from Settings.setMovementArea(int, int) which defines part of the viewport in which image can move.

getEffectiveMinZoom

@Deprecated
public float getEffectiveMinZoom()

Deprecated. Use getMinZoom(State) instead.

getEffectiveMaxZoom

@Deprecated

@Deprecated
public void getEffectiveMovementArea(android.graphics.RectF out,
                                                 State state)

Deprecated. User getMovementArea(State, RectF) instead.
