In the former articles in Image processing on Android series, the image is displayed in shrinked version to suit the device's screen. It's modified display in scrollable true size.

Modify the layout, main.xml, to embed the ImageViews inside nested HorizontalScrollView and ScrollView. Such that the ImageViews will be displayed in full-size and scrollable.
