<DIV><FONT size=2>hi,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>i am now drawing a 2d contour map of some grid
data.</FONT></DIV>
<DIV><FONT size=2>the problem is that i can't find an easy way to keep
</FONT></DIV>
<DIV><FONT size=2>the aspect ratio of the map </FONT><FONT size=2>when i resize
the window.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>what i want is the contour map can act just like the
common </FONT></DIV>
<DIV><FONT size=2>3d actors: the map is always in the center of the window and
</FONT></DIV>
<DIV><FONT size=2>it doesn't </FONT><FONT size=2>change its ratio the the window
resizes.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>obviously this is up to the coordinate system. i almost
tried</FONT></DIV>
<DIV><FONT size=2>everyone:display,viewport,view (normalized ones shouldn't be
</FONT></DIV>
<DIV><FONT size=2>used here,right?)... but none of them works.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>which one should i use, and how ?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT
size=2>ContourActor->GetPositionCoordinate()->SetCoordinateSystemTo???();</FONT></DIV>
<DIV><FONT size=2>ContourMapper->SetTransformCoordinate(???);</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>thanks.</FONT></DIV>
