PDF doc images look surreal

[robe]

Not a major issue, but just noticed the PDF output of the image magick images looks kind of surreal. From an artistic standpoint, it looks very interesting, but I suppose from a practical standpoint sometimes may be hard to follow the diagrams.

I think maybe its because the png transparency is not being maintained its being forced into a jpeg model and as I recall I think that's what happens whne you save a transparent png without extra args. I recall having done this before with image magick, but can't recall the magical incantation or which project I had it in.

Fixed.
