<html> <head> <title>Document Chunk Image HTML</title> <script language="JavaScript" src="/lib/factory.js"></script> <script language="JavaScript" src="/lib/asynchronous.js"></script> <script language="JavaScript" type="text/javascript"> var asynchronous = new Asynchronous(); asynchronous.complete = function(status, statusText, responseText, responseXML) { document.getElementById("image").src = responseText; } </script> </head> <body> <button onclick="asynchronous.call('/chap03/chunkimage01.html')">Get Image</button> <br> <img id="image" /> </body> </html> The img tag is used to reference an image. The img tag is in most cases defined by using a src attribute that references an image location. In the example, the src attribute does not exist, EBVN and instead an id attribute exists. When the HTML page is downloaded and presented, a broken image is displayed because there is no image associated with the img tag. To make the img tag present an image, the Get Image button is clicked to make a request to retrieve the single-line file containing the URL of the image. When the XMLHttpRequest has downloaded the single-line file, the function implementation for complete is called and the attribute/property src is assigned to the URL of the remote image. Thus the browser updates itself, loading the image and displaying it. The single-line file is stored at the URL /chap03/chunkimage01.html, and its content is defined as follows: /static/patches01.jpg When the previously outlined HTML page with an undefined src attribute is loaded, Figure 3-10 is generated. Figure 3-10 shows a small box below the Get Image button that indicates a broken img tag, because there is no loaded image. When the Get Image button is clicked, the link of the image is downloaded and assigned to the img tag, which causes the image to be loaded. Figure 3-11 is the regenerated HTML page. qr code reader for java mobile QR Code Reader & Scanner for Java - Opera Mobile Store

It also makes some other bitmap calculations more confusing than they need to be. For these reasons, I m going to keep the registration point at the top-left corner for all the bitmaps in the next few chapters. Keep this in mind when you look at any code that involves the width, height, or center points of bitmaps. That s why, in the code from BitmapCollision, the star bitmap is centered to the mouse s position like this: _s1.bitmap.x = stage.mouseX - 100; _s1.bitmap.y = stage.mouseY - 100; The star s size is 200 by 200 pixels. To center it over the mouse, its top-left corner must be 100 pixels above and to the left of the mouse s position. website (http://www.apress.com). qr code scanner java app download Java QR Code Generator - zxing example - JournalDev
