Operations
public PicWeb()
- Notes
- PicWeb class constructor creates the user interface Panel
- and initializes a work thread
-
private final void ProcessGifs(String directory)
- Notes
- Method ProcessGifs processes an entire directory tree by
- calling itself recursively
-
static void main(String[] args)
private final Image newImage(String file_name, int scale_mode)
public void paint(Graphics g)
public void run()
- Notes
- The 'run' method is called when the work thread is started.
- The work thread sleeps until there is work to be done. We
- use a separate work thread so that the user interface does not
- "freeze up" when PicWeb is processing image files and generating
- HTML documents.
