AJAX Features

AJAX (Asynchronous JavaScript and XML) Enabled Image Controls. LEADTOOLS Web Viewer controls enable you to add fast, interactive image viewing to your AJAX web applications. The server control updates without posting the entire page back to the server. HTTP handlers are included to serve non-browser supported formats, and to obtain file information on files located on the server or accessible via http. Support also includes a Pan Viewer control. Ships with source code for complete document and color image processing demo applications.

AJAX is a web development technique for creating interactive web applications using JavaScript function calls. In order to increase the web page's interactivity, speed, functionality, and usability, it asynchronously exchanges data bits with the server so that it does not interfere with normal page loading. Data retrieved using the technique is often formatted using XML. Because it is based on these open standards, it is a cross-platform technology usable on many different operating systems, computer architectures, and Web browsers.

Key Features

LEADTOOLS AJAX support enables you to:

• Display any LEADTOOLS supported file format on an ASP.NET 2.0 web form.
• Display any LEAD image file format by converting it to a browser-friendly format (JPEG, GIF, PNG and BMP) on the fly.
• Automatically handle zooming and scrolling.
• Support large images through tiling, by loading tiled sections of an image on-demand when the relevant section of an image is zoomed into view. Image tiling decreases time-to-view on the WebForm.
• Support simple- and strong-client javascript classes to update the server control with near-same naming conventions (as for the server control properties and methods).
• Serve non-browser supported formats.
• Get file information for files on the server or accessible via http using http handlers.
• Create AJAX-style Web applications that deal with huge images, for example, geospatial imaging applications like Google™ Earth. Only the portions of the image required for display are downloaded and decompressed.
• Encrypt cache folder ability.
