SigPlusExtLite SDK


The Topaz® SigPlusExtLite™ SDK offers a means for developers to capture handwritten signatures for web applications running in the Chrome and Firefox browsers.




SigPlusExtLite supports usage in remote environments, such as Citrix and Terminal Server.




This SDK can also be used to export a base64-encoded PNG image of the captured signature.




If you are a developer, view the SigPlusExtLite Software Integration Guide for instructions on Chrome and Firefox integration.




If you are an end user, view the SigPlusExtLite User Installation Guide for instructions on using SigPlusExtLite in Chrome and Firefox.




After following the steps in the guides listed above, test signature capture capabilities with the SigPlusExtLite Demo. For more information, view the Topaz Web examples, demos, and source code.
