 Well I did use a very large width and the result
 grow past the board size:
./pcbsilk -W 1204mm TestLogo.jpg

OK, that'll be the problem then,

Anyway, I might give it 
a shot using grep, cut, sed and sort to manipulate the X and Y values -- 
even though I think it's going to be pretty inefficient.

You don't need to.

Well, I already came up with this oneliner for the minimum y value from the pcb logo file:

ymin=`egrep "\[[0-9]+\ [0-9]+\]" $silkname.pcb | cut -d " " -f2 | cut -d "]" -f1 | sort -n | head -1`

Below I made a 60mm wide logo, its minimum y extent was 220.4103mm.

Yup, that seems right:

echo $ymin -> 867757
yshift= echo 'scale=2;-$ymin*25.4/100000' | bc
echo $yshift -> -220.41

 Then I rerun pstoedit but told it to move the result
220mm up:

$ ./pcbsilk -W 60mm TestLogo.jpg 
$ Pcb_test.pl polygon  TestLogo.pcb 
Layer 1, name poly:
        0.0000 220.4103mm 59.9996mm 279.0472mm
Layer 10, name silk:
$ pstoedit -q -f "pcb:-mm -tshifty -220"  TestLogo.eps TestLogo.pcb

And unfortunately, this is where things go wrong. It works just fine with the numerical value:

$ pstoedit -q -f "pcb:-mm -tshifty -220.41" -ssp TestLogo.eps TestLogo.pcb

But when I replace -220.41 with the variable $yshift calculated above, it no longer works; also see line 88 of the attached script version. It appears that $yshift is not expanded, even though double quote marks were used.

$ Pcb_test.pl polygon  TestLogo.pcb 
Layer 1, name poly:
        0.0000 0.4102mm 59.9996mm 59.0471mm
Layer 10, name silk:
$

The only thing remaining is to edit the file, removing the empty
layer and rename layer 1 to something like: Layer(5 "top silk" "silk").

Yes, I already fixed the layers, and I also created an extra command line switch to select the number of layers, with a default of 2, which causes top silk to end up on layer 6. The X size is now also correct, so all that still needs to be done is shift the logo to the top. Once everything works, the extra echo commands for $ymin and $yshift can be commented out, and removing the intermediate files can be restored.

Richard Rasker
