C.4 Image Manipulation

Navigator 3.0 supports image manipulation with the following powerful new features. Chapter 16, Special Effects with Images, has complete details.

• The Image object represents an image, either on-screen or off. Setting the src property of an Image object will cause it to load (and display if it is an on-screen image) the image stored at the specfied URL.

• The Document.images[] array contains a complete list of the images displayed within a document.

• The Image() constructor allows the creation of off-screen images, which can be used to preload images that will be required for animations or other image manipulation techniques.

• The onload(), onerror(), and onabort() event handlers of the Image object help determine the status of images that are loading.

• The complete property of the Image object specified whether it is still being loaded or not.
