Java通过页面获取图像文件，我们打开一个页面时候通常都会看到此页面带有图像信息，通过这些图像我们可以看到生动的画面。我们可以通过页面来载入图像文件。本例就是通过编程来实现这一功能。运行程序，用浏览器打开useTrackedImage.html 文件，载入图像文件，并获取该图像文件。本Java例子主要是利用java.awt.MediaTracker 类来跟踪许多不同图像的载入状态并把它们组织为逻辑集。-Java obtain image files by pages, when we open a page usually see this page with the image information through these images we can see a vivid picture. We can load image files by page. This example is programmed to achieve this functionality. Run the program, open the browser useTrackedImage.html file, load an image file, and get the image file. The Java example is the use of java.awt.MediaTracker class to track the status of a number of different images and load them organized into logical sets.
