org.apache.turbine.modules.screens.RawScreen
public abstract class RawScreen
Base class for writing Screens that output binary data. This class
is provided as a helper class for those who want to write Screens
that output raw binary data. For example, it may be extended into
a Screen that outputs a SVG file or a SWF (Flash Player format)
movie. The only thing one has to do is to implement the two
methods getContentType(RunData data)
and
doOutput(RunData data)
(see below).
You migth want to take a look at the ImageServer screen class
contained in the TDK.
