Getting Images Downloaded

• The Applet class provides a method getImage, which retrieves an image from a web server and creates an instance of the Image class.

• Image img =

  • getImage(new URL("http://www.tc.com/image.gif"));

• Another form of getImage retrieves the image file relative to the directory of the HTML or the directory of the java code.

  • Image img = getImage(getDocumentBase(), "images/image.gif");
  • Image img = getImage(getCodeBase(), "images/image.gif");

• Note that the Image class in java.awt has many methods for images, such as getWidth( imageobserver) and getHeight( imageobserver ), which return the width and height in pixels.

• Images can be created from either gifs or jpegs.
