Why can't you simply select, copy and paste it from the silk layer to
the outline layer?

Hey folks. I'm designing a board that needs to have a very
complex <br>
outline. Starting from an image file, I've gotten what I need
into the <br>
silkscreen layer, but now I'd like to essentially take the
shape that's <br>
there and draw a line 1mm or so around the outside of the
entire shape, <br>
for the outline.<br>
<br>
Can anyone suggest an automated way to do this? I'd just
trace it, <br>
but the outline is, as I said, very complex.<br>
<br>
Thanks,<br>
