Examples of OutputProcessor

org.jfree.layouting.output.OutputProcessor
The output processor defines, which processing-step implementation will be used during the layout process. Obviously, what computations are required depends heavily on the desired result. @author Thomas Morgner
org.pentaho.reporting.engine.classic.core.layout.output.OutputProcessor
The output-processor receives the layouted content and is responsible for translating the received content into the specific output format. The output processor also keeps track of the number of received pages and their physical layout. @author Thomas Morgner
