First I like to say "Hello" to this forum!

There are a few pdf files which can not be converted to jpg. No problem to open them with Acrobat or Preview, though. This line never returns:

Code: Select all

convert -colorspace rgb example.pdf example.jpg

After cancelling it these errors appear:

Code: Select all

convert: Postscript delegate failed `example.pdf': No such file or directory @ pdf.c/ReadPDFImage/612.
convert: missing an image filename `example.pdf' @ convert.c/ConvertImageCommand/2766.

Any ideas what could be the reason for this?

Mac OS-X 10.5.6
ImageMagick @6.4.8-9 (graphics, devel)
GPL Ghostscript 8.62 (2008-02-29)

Thanks in advance for any hint!

EDIT:
Meanwhile I've realized there is a newer version of gs. Now there is a more precise error when I try to open the pdf with gs (before that it was showing a "bus error" only):

Code: Select all

But this doesn't really help me

Ok, found out it is a bug in ghostscript:
http://bugs.ghostscript.com/show_bug.cgi?id=689734

gs -dNOTRANSPARENCY example.pdf shows the file (not perfectly but anyway).

Now the question is: Is there any chance for a workaround in ImageMagick? More precise I need one for RMagick.

Does noone else run into this problem?

See if this helps:

convert -colorspace rgb +matte example.pdf example.jpg

Great! This fixes the problem!

Thank you so much you saved my day!!

Ok, I was a bit too fast. Everything works fine for my test files. But I tested even the file from this corresponding thread: viewtopic.php?uid=12608&f=3&t=12944

For this one your solution doesn't work unfortunately. It says

Code: Select all

**** Warning:  File has an invalid xref entry:  4040.  Rebuilding xref table.

and hangs up.

But this thread should be closed anyway since I believe we are talking about two different problems.
