[ ![Download](https://api.bintray.com/packages/bintray/jcenter/it.sephiroth.android.library.imagezoom%3Aimagezoom/images/download.svg) ](https://bintray.com/bintray/jcenter/it.sephiroth.android.library.imagezoom%3Aimagezoom/_latestVersion)

ImageViewTouch is an android `ImageView` widget with zoom and pan capabilities.

This is an implementation of the ImageView widget used in the Gallery app of the Android opensource project.

Checkout the repository and run the **ImageViewTouchTest** project to see how it works.

Beside the superclass **setImageBitmap** method it offers the following methods:

* `setImageBitmap( final Bitmap bitmap, Matrix matrix );`

* `setImageBitmap( final Bitmap bitmap, Matrix matrix, float minZoom, float maxZoom );`

If you want to load a new Bitmap with a particular zoom/pan state (let's say the same from another ImageView ), you can call:

	Matrix matrix = mImageView1.getDisplayMatrix();

	mImageView2.setImageBitmap( bitmap, matrix );

## Tweaks

The initial display state can be set, using `public void setDisplayType( DisplayType type )`, as:

* `DisplayType.FIT_TO_SCREEN`: The image loaded will always fit the current view's bounds.

* `DisplayType.NONE`: The image will be presented with its current dimensions if smaller than the image bounds, otherwise it will be scaled to fit its contents inside the screen.

* `DisplayType.FIT_HEIGHT`: The image loaded will always fit the height of the current view.

* `DisplayType.FIT_WIDTH`: The image loaded will always fit the width of the current view. 

The default display state is `DisplayState.NONE'.
