In their own words
VirtualViewer
VirtualViewer is the former name of PrizmDoc for Java, Accusoft’s document-viewing technology for enterprise content management applications. It provides viewing, annotation, redaction, page manipulation, and conversion for formats including PDF, Word, Excel, AFP, DWG, and TIFF. Users can split and merge documents, compare documents, use OCR, and work with thumbnails, bookmarks, and virtual documents assembled from pages across sources. Browser access supports viewing on computers, tablets, and smartphones without client software. Cloud, on-premises, and hybrid deployments are available, with JavaScript and REST APIs, callbacks, a RESTful content handler, and connectors for Alfresco, IBM, and Pegasystems. Accusoft lists controls to disable downloads and a secure-redaction feature. The technical environments include Tomcat, WebSphere, Java 11 or higher, Java-compatible operating systems, and several hosting providers. The documentation says versions 5.12.0 and earlier used the VirtualViewer name; the product is now called PrizmDoc for Java.
