org.autoplot.pngwalk.WalkImageSequence

This class maintains a list of WalkImages and provides functionality for navigating through it. Whenever the current index is changed, whether explicitly set or via one of the navigation functions, a PropertyChangeEvent is fired. This allows UI code to control the index and view code to respond.

Access is also provided to the {@link WalkImage} objects so that view code can retrieve images, thumbnails, etc.

WalkImageSequence( String template )

Create an image sequence based on a URI template.
