Recently, we released a huge update to Version 19 which included a new Document Composer. We already wrote about its amazing features, simple interface, and seamless integration with the Document Viewer, and now you can also watch this video to see how easy it is to compose a virtual document on the fly from any number of pages in any order and from multiple source documents.
If you haven't tried out the latest version of LEADTOOLS that includes this new Document Composer interface, download the latest from here, or try the live online sample application.
