Thanks for the suggestion.

I've tried both ImageMagick convert and Mac Graphic Convertor.  Tried 
saving in other formats, and processing them in the other format. 
Tried converting them back to pngs and reprocessing them in that.  I 
saw something on the net about bounding boxes and editing eps files 
by hand.  That's where I noticed that the bounding box for the bad 
images did not start at 0,0.  So I converted to eps and tried 
"normalizing" the bounding box to start at 0,0 and had no luck.

I ended up using convert -resize 400 to make the pngs scale properly 
for the page and then using docbook2pdf (openJade).  It worked.  I 
tried the resized images with xmlto and it was still broken.
