Any object can have a global opacity, yes. It can also have a fill opacity, stroke opacity, and so on. Consider an object which has a gradient fill; one stop is yellow at full stop-opacity and one is red at 0.2 stop-opacity. (You could also add stroke opacity, fill-opacity, or even global opacity, to the same object). Now consider a gradient where both stops have the same color and same opacity. (This is what people used to do to make a paaint server, before we had a solidColor element). So its essentially a single stop gradient; and it has a solid-opacity property analagous to the stop-opacity. -- Chris Lilley mailto:[EMAIL PROTECTED] Interaction Domain Leader W3C Graphics Activity Lead Co-Chair, W3C Hypertext CG _______________________________________________ CREATE mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/create
