PrizmDoc® for Java vs. Lark

PrizmDoc® for Java, formerly known as VirtualViewer®, is a comprehensive suite of Java-based APIs designed to seamlessly integrate advanced document viewing and processing capabilities into web applications. It supports a wide array of document types, including AFP, Word, PDF, PNG, PCL, and TIFF, enabling users to view, annotate, redact, and manipulate documents directly within their browser without the need for additional software installations.
