<DIV> </DIV>
<DIV>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:</DIV>
