public class ImageTool
extends CreationTool

A tool to create new figures that implement the ImageHolderFigure interface, such as ImageFigure. The figure to be created is specified by a prototype.

Immediately, after the ImageTool has been activated, it opens a JFileChooser, letting the user specify an image file. The the user then performs the following mouse gesture:

1. Press the mouse button and drag the mouse over the DrawingView. This defines the bounds of the created figure.

Design Patterns

Prototype
The ImageTool creates new figures by cloning a prototype ImageHolderFigure object.
Prototype: ImageHolderFigure; Client: ImageTool.
