ZoomableView

============

A base view implementing Zoom, Scale, Scroll, Fling

![ZoomView Anim](https://github.com/ncornette/ZoomableView/raw/master/demo/anim.gif)

### How-to : 

* Insert the view in your layout : 

```xml

    

```

* Define a static picture to display by using `mapref` attribute : 

```xml

app:mapref="@drawable/chicken_cartoon_500"

```

* Grab the instance of `ZoomView` from you activity to control the zoom level, etc...

```java

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        final ZoomView zoomable = (ZoomViewTouchable) findViewById(R.id.zoomable);

    }

```

* Instead of using `mapref` attribute, you can provide your own bitmap, so you can draw through its canvas : 

```java

Bitmap bmp;

...

zoomable.setMap(bmp)

```

### Attributes :

Zoom view can also handle some extra attributes : 

```xml

        

        

         

         

         

         

         

        

        

         

         

         

        

        

         

         

```
