Methods

o copyright 
 public static String copyright()
Copyright method to ensure that short copyright string appears in class file.

o combine 
 public static Image combine(Image under,
                             Image over,
                             int x,
                             int y)
Generate an Image which whows the results of drawing over on under at the point (x, y). Returns null if the Image cannot be created. The Image will not be created if over is not contained withtin under.

o createImage 
 public static Image createImage(int width,
                                 int height,
                                 Toolkit t,
                                 int pixels[],
                                 boolean hasAlphaPixels)
Return an image based on the given pixel map. The alpha values (bits 24-31) must be non zero for a visible image.

o createImage 
 public static Image createImage(int width,
                                 int height,
                                 Toolkit t,
                                 int pixels[])
Return an image based on the given pixel map. The alpha values (bits 24-31) must be non zero for a visible image.

o createImage 
 public static Image createImage(Image sourceImage)
Return an Image which is a copy of the supplied Image.

o getImageFromJar 
 public static Image getImageFromJar(String imageSource,
                                     Class resourceClass,
                                     Component component)
Return an Image created from a file of the supplied image source name to be found in the Jar file containing the supplied class. If the image is not found in the Jar file, the supplied Component is used to try to locate a parent Applet, and then use that Applet to load the named image.

o getImageFromJar 
 public static Image getImageFromJar(String imageSource,
                                     Class resourceClass)
Return an Image created from a file of the supplied image source name to be found in the Jar file containing the supplied class.

o getColorArray 
 public static Color[] getColorArray(Image sourceImage)
Return an array of Colors which are used in the supplied Image.

o getColorTable 
 public static Hashtable getColorTable(Image sourceImage)
Return a hashtable of Colors which are used in the supplied Image. The Colors are keys to Integers containing their sequence number.

o getIntArray 
 public static int[] getIntArray(Image image)
Return an array of ints represnting the pixels from the supplied Image.

o waitForImage 
 public static void waitForImage(Image image)
Wait for the specified image to be fully loaded.

o waitForImages 
 public static void waitForImages(Image images[])
Waits for the array of specified images to be fully loaded.
