graphicImage (VDL Documentation Generator

Description:

PrimeFaces GraphicImage extends standard JSF graphic image component with the ability of displaying binary data like an inputstream. Main use cases of GraphicImage is to make displaying images stored in database or on-the-fly images easier. Legacy way to do this is to come up with a Servlet that does the streaming, GraphicImage does all the hard work without the need of a Servlet.
