Making a bitmap logo spin in Xara3D Part 2

[DAL]

I did have one question about saving with X3D. When I save the image it seems to automatically save with blank space around it that is unwanted, as you can see in my sample. What I'd like to do is save to a specific size but only the image area without the extra blank space. Is there a way to do that? I've mucked with it a bit trying the frame box and such but nothing successful so far. Any thoughts?
