The data file contains different channels from a satellite. </DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I've read the data into memory and now have three arrays of 8-bit numbers. I can combine the data into a single array if I have to. Is there a way to tell VTK to display that array as an RGB image?</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks, </DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>-- Gala</DIV><BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Gala Wind</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">(301) 614-6221</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica"><A href="mailto:wind@climate.gsfc.nasa.gov">wind@climate.gsfc.nasa.gov</A></FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Code 613.2, Climate and Radiation</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">SSAI, Inc.</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">NASA/GSFC</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Greenbelt, MD 20771</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">/*--------------------------------------------------------------------</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica"><SPAN class="Apple-converted-space"> </SPAN>-- There's always a way, you just have to find it.</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica"><SPAN class="Apple-converted-space"><SPAN class="Apple-converted-tab"> </SPAN></SPAN>( B.
