[magick-users] images in PDFs losing transparency in conversion

[Jason LaPier]

Hi all -
I'm having trouble with some PDFs that have some positioned, transparent
images in them. When I convert these PDFs to jpg or png, the floating images
are no longer transparent. There is only one layer in this PDF - the
floating images are not on separate layers, so the "-layers flatten" option
does me no good.

I tried converting the image with ghostscript and it actually created the
image correctly. I hope that means I'm just missing an option in imagemagick
to convert these right.

Here's the original PDF:

The result of imagemagick convert (and rmagick, which is what I am using in
production):

And the result from gs:

I'm using ImageMagick 6.3.7, in Ubuntu 8.10.

Thanks,

- Jason L.
