LEADTOOLS Releases Updates to V20 Including Advanced Security Features for the HTML5/JavaScript Document Viewer


LEADTOOLS received several updates to its document and medical imaging toolkits today.Most notably, the LEADTOOLS HTML5/JavaScript Document Viewer now has the ability to run within even the most restricted environments without compromising security. Several under-the-hood updates including logging, diskless caching, configuration settings, and the like all contribute to create a lightweight, web-based viewer that can be hosted on both Windows and Linux servers, as well as third-party cloud hosting services such as Microsoft Azure.

Additionally, LEADTOOLS added support for IBM FileNet P8 annotations. This has been a popular request for customers using the HTML5/JavaScript Document Viewer in conjunction with a FileNet ecosystem. It also addresses compatibility concerns for customers migrating from FileNet to a new ECM vendor yet want to maintain complete control of their FileNet P8 annotations.
