     /**
30 |  |
      * Base class for writing Screens that output binary data.  This class
31 |  |
      * is provided as a helper class for those who want to write Screens
32 |  |
      * that output raw binary data.  For example, it may be extended into
33 |  |
      * a Screen that outputs a SVG file or a SWF (Flash Player format)
34 |  |
      * movie.  The only thing one has to do is to implement the two
35 |  |
      * methods <code>getContentType(PipelineData data)</code> and
36 |  |
      * <code>doOutput(PipelineData data)</code> (see below).
37 |  |

      * <p> You might want to take a look at the ImageServer screen class
39 |  |
      * contained in the TDK.<br>
