All Implemented Interfaces:

public class SlideShow
extends javax.swing.JComponent
implements java.lang.Runnable, java.awt.event.KeyListener, java.awt.event.WindowListener

Display a series of images as a full-screen slide show. The following key-presses are active during the show.
Left arrow reverses, to go backwards through the series of images.
Right arrow goes forward.
Up arrow speeds up by 2 (halving the interval).
Down arrow slows down by 2.
The space bar pauses and resumes the show. While paused, the left and right arrow keys can be used to step to the next or previous slide.
Any other key ends the show and clears the window.
One constructor enables the slide show to be driven by a script listing
file paths, one per line. As well as listing full file paths the script can contain special lines beginning with upper case keywords:
PATH pathname // prefix for all subsequent file names/paths
OPEN fileName // pauses the show & the image file is shown in an ImFrame;
// the show resumes when the ImFrame is closed.
PAUSE // causes the slide show to start in paused mode: user steps through.
RESUME // resumes automatic stepping.
