public Settings setViewport(int w,
                            int h)
```
    Setting viewport size.
    Should only be used when implementing custom GestureView.
  - setMovementArea
```
public Settings setMovementArea(int w,
                                int h)
```
    Setting movement area size. Viewport area will be used instead if no movement area is specified.
  - setImage
```
public Settings setImage(int w,
                         int h)
```
    Setting full image size.
    Should only be used when implementing custom GestureView.
  - setMaxZoom
```
public Settings setMaxZoom(float maxZoom)
```
    Setting max zoom level.
    Default value is MAX_ZOOM.
  - setOverzoomFactor
```
public Settings setOverzoomFactor(float factor)
```
    Setting overzoom factor. User will be able to "over zoom" up to this factor. Cannot be < 1.
    Default value is OVERZOOM_FACTOR.
  - setOverscrollDistance
```
public Settings setOverscrollDistance(float distanceX,
                                      float distanceY)
```
    Setting overscroll distance in pixels. User will be able to "over scroll" up to this distance. Cannot be < 0.
    Default value is 0.
  - setOverscrollDistance
```
public Settings setOverscrollDistance(android.content.Context context,
                                      float distanceXDp,
                                      float distanceYDp)
```
    Same as setOverscrollDistance(float, float) but accepts distance in DP
  - setFillViewport
