<div>
<p class=MsoNormal>I'm having a wierd problem with vtkProperty. I create a line
and specify a color for it. The problem is that some (actually
most) RGB values I pass to vtkProperty won't generate the
related colour. say for example slateblue identified by R=147, G=112 and
B=219 (<a
href="http://www.ecrion.com/Support/Resources/XSL-FOTutorial/ApendixA.xml.html">http://www.ecrion.com/Support/Resources/XSL-FOTutorial/ApendixA.xml.html</a>)
appears as white?????!!!!!!! and it's not only that color. Can someone
tell me what's the solution the create any RGB color. Here's my code:<o:p></o:p></p>
