Remarks

The WebThumbnailViewer can display the pages of a multi-page image in an auto-scrollable view.

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

Only the viewed thumbnails images are loaded (load OnDemand).

This Control works only with 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

Install them in the Global Assembly Cache (GAC). For more information on this method, refer to The Microsoft Gacutil Tool.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
