Example

Remarks

The TiledImageViewer can display any image file format supported by LEADTOOLS.

To use this control properly, LEADTOOLS binaries must be installed on the server machine.

Set the ImageUrl property to a valid Image Url.

The TiledImageViewer control can automatically handle zooming and scrolling.

Use this class to create AJAX-style Web applications that deal with huge images such as Geospatial imaging applications like GoogleTM Earth. Only the portions of the image required for display are downloaded and compressed.

This Control works only on ASP.NET 2.0.

Be sure that the DLLs in the LEADTOOLS I/O Library are available to your application. There are two ways of doing this:

  • Install the DLLs in the application's directory
