Fred, I have not upgraded IM. I am running the stock installation from Ubuntu.

It bothers me that gs is not showing in the list. Though on windows it never shows. On my mac and I thought other unix systems it would show.
What do you get from
convert -list configure | grep "DELEGATES"
Does it show there?

I imagine you want the verbose on the second command, no?
Code: Select all
$ convert logo: logo.pdf
$ convert -verbose logo.pdf logo.jpg

OK. So although it does not show up in your list of delegates, it does work and still thinks the PDF is PNG.
Mine show PDF and not PNG for the input:
Code: Select all
convert -verbose logo.pdf logo.jpg

In my opinion, something seems clearly wrong with your IM or ghostscript.

I recompiles IM 6899 and ran the same identify command and it does show PNG.

So it must be a factor of that version of IM, which may have a bug. The IM developers would have to say for sure.
Perhaps the older systems were reporting the raster type for imbedded raster images in the PDF shell?

Any updates on the situation of this bug?
