Further Product Details

The 3-Heights™ Java Document Viewer is a powerful and flexible component for displaying and printing documents and images and converting them into raster images. The component is particularly suitable for embedding in applications such as DMS and ECM systems and enabling a user navigation that is independent of the document format. 

The 3-Heights™ Java Document Viewer offers exceptional flexibility in GUI design, format versatility (ISO standards), high performance and low memory space requirements (thanks to the use of runtime libraries).

Developers have free rein with regard to the design of the user interface. The component is delivered together with the source code for a complete Java application (Java Swing Framework) that is easily adapted to the application's requirements. In particular, functions for editing comments and remarks managed separately from the document can be integrated in the same user interface.
