<p class=MsoNormal>I am using vtkAVIWriter to generate an AVI movie in
Java. However, there are two problems:<o:p></o:p></p>

<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span

every 200-500 milliseconds, the frame will change.<o:p></o:p></p>

</span></span><![endif]>Even though I change the scalars and update the window
to image filter, the image will not change colors based on the scalar changes.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Below is a code snippet:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> public void createAVI () {<o:p></o:p></p>
