<p class=MsoNormal><font size=2 face=Arial><span lang=EN-US style='font-size:
10.0pt;font-family:Arial'>I understand how to set up a reader to read a file
and then connect it to a filter to filter it in some way and finally to connect
an image to the output of the filter which is then displayed or something but
what I can't quite figure out is given this final image object which I
display how can I do some further filtering on it so that the result ends up
back in the same object which is being displayed and ensure that all the memory
is managed nicely. </span></font></p>
