Vista - Loading an XAML file into a DrawingVisual

Is it possible to load an XAML file and then put the contents of that file
into a DrawingVisual? I'm playing around with making some graphic objects
with the Expression Graphic Designer and can load them with the XamlReader
object. The Object I get back is a Canvas which if you trace down far enough
you get to a Visual Object. Unfortunately I don't see a way to 'blit' this
Visual into a DrawingVisual object. Is there a way to do this?

Thanks-

John

Consider using Drawings instead - you can use EID to produce Drawings
instead of an Element tree (I'm afraid I don't have it in front of me to
check precisely how, you may need to convert it to a DrawingBrush). You can
then take the Drawing from the XamlReader and do:

DrawingVisual vis;
....
DrawingContext ctx = vis.RenderOpen();
ctx.DrawDrawing(myDrawing);
ctx.Close();

Thanks, that did the trick. I was able to import the resource dictionary and
pull the DrawingImage out of that. The only issue is that I loose all of my
effects ( shadows, etc ). I'm guessing that's a limitation of the resource
dictionary.

Hrm... that depends on how you were creating those effects. If you were
using BitmapEffects to create shadows, etc, you can still use those in a
graph of Drawings (DrawingGroup has a BitmapEffect property) - it may be
that EID doesn't preserve them when doing the conversion.

If you were not using BitmapEffects, what technique were you using?
