Answer 1

The crudest forms of digital zooms simply scale an image larger and crop to a certain visible region. On the iPhone, you can do this easily by capturing an image from the camera, placing it in a UIImageView, and applying a scaling transform to the view.

Answer 2

Consider these Categories for NSImage for ways in which you can zoom and crop an image in Objective-C.
