Class ImagePaintable

  edu.neu.ccs.gui.AbstractPaintable
      edu.neu.ccs.gui.ImagePaintable

All Implemented Interfaces:

JPTConstants, Paintable, SupportsPropertyChange, SwingConstants

public class ImagePaintable

extends AbstractPaintable

An ImagePaintable creates an AbstractPaintable using an image, image icon, filename, or URL.

Specifically, an ImagePaintable object may be created using one of the following:

• an image specified by an Image object,
• an image specified by an ImageIcon object,
• an image specified by a filename,
• an image specified by a URL.

In 2.3.2, the method getBounds2D was modified to use the default Bounds2D rectangle if that rectangle is non-null before making any other tests or computations.

In 2.3.3, the code was made parallel to that of the new class ImagePaintableLite. The class ImagePaintable retains image data throughout the life time of an instance and thus may paint more rapidly at the cost of larger memory footprint.

In 2.3.5, the class was refactored to be consistent with the new Paintable interface and the new AbstractPaintable class.

In 2.4.0, this class was updated to be consistent with refinements to the Paintable interface.

Since:

2.3

Version:

2.4.0
