46 * This class represents an Image loaded from a file which is shown on the
47 * screen. Loading of the Image from disk occurs in the constructor, and takes
48 * approximately one second per mb of the Image file size. <br>
49 * <br>
50 * Currently Supported (Tested) Image formats:<br>
51 * BMP<br>
52 * JPG<br>
53 * GIF<br>
54 * GIF (Animated)<br>
55 * <br>
56 * Currently only the default size of the Image is supported, but future
57 * versions may support scaling.
