Overview

This course explains the Flash Actionscript MovieClip-method startDrag(...) and its parameters. With this knowledge and some more we build a simple but nice image viewer, where you can zoom in and out and drag the visible part of the image around. It also includes a small Actionscript-generated preview thumbnail which shows where in the picture you are when you are zoomed in. Of course, the source code for this course and therefore for the image viewer MovieClip is available here! The code is Actionscript 2.0, but it is exactly the same when you use AS 3.0, only that some names have changed.
