Files to be Included with your Application


Files for redistribution are installed by the LEADTOOLS setup.


You may not copy or redistribute any of the following files without obtaining the proper license. In some cases, the license is included with your initial purchase of LEADTOOLS. In other cases, you must obtain a license from a third party or enter into a royalty agreement with LEAD to obtain the proper license. For these special licensing situations, see the notes below accompanying the specific file.


Use and deployment of the .JS files with your application requires that a server license be purchased for each webserver the .JS file is installed upon. If you are using any other portions of LEADTOOLS on your web server, you may need additional licenses.

Provided you have obtained the necessary license, you may deploy the .JS files on the licensed webserver for use in conjunction with your application through the http protocol supported by your webserver and your end users web-browsers. The .JS files may not be redistributed, copied or otherwise made available for use by any other application other than the end user web application for which you have obtained a valid server license. You may not remove any copyright strings that are included with the .JS files, or otherwise modify the .JS file or reverse engineer, disassemble, or decompile it or otherwise attempt to discover the underlying algorithms or other trade secrets contained in the software.

The following table summarizes the .JS files that you can use in your applications.
