> I confirm it can't read the pdf from the OP, or any other pdf.

Good to hear that I am not the only one seeing this bug.

> Perhaps it is a bug in GS 9.10 or an error installing it?

This cannot be because I did not touch GS after its installation. When I now uninstall IM 6.8.8-9 and install IM 6.8.0-4 everything works fine. When I then uninstall IM 6.8.0-4 and install IM 6.8.8-9 I can no longer convert my PDF.

- take e.g. this PDF:
http://uwe-sthr.weebly.com/files/theme/Tachyonen.pdf
- use IM 6.8.8 and run the command

convert -define pdf:use-cropbox=true Tachyonen.pdf Tachyonen.png

Result:
convert.exe: `%s' (%d) "C:/Program Files/gs/gs9.10/bin/gswin32c.exe" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE ...

I fully agree. This would solve the problems I mentioned and I think this easy to achieve.

IM currently requires a registry entry either in HKLM or HKCU where the locations of the delegates are stored. This requirement makes it impossible to install several programs that use IM:
Assume program A as well as Program B use IM to convert images. So what happens is that the user installs ...

@donovaly: Your issue seem to be different. IM cannot find GS in your case. So with your install convert should fail for all pdfs (this requires GS) - and not only for some pdfs, as reported above.

Yes, this was my fault. I had a broken installation.
That a part of my PDFs worked had other ...

Dear developers,

I use IM for an open source programs on Windows (namely for LyX). I have an installer that installs the whole bundle of LyX, Ghostscript and IM. It works fine so war, but only if the installation is done with admin permissions. But for none of the programs admin permissions are ...

The bug is that the

-define pdf:use-cropbox=true

switch does not work anymore.
Using
convert -define pdf:use-cropbox=true -depth 8 -flatten "pdf:testgraph.pdf" "png:testgraph.png"
fails but
convert -depth 8 -flatten "pdf:testgraph.pdf" "png:testgraph.png"
works.

This regression has been ...

I can confirm the bug. (This is independent of 32bit or 64bit Windows.) With IM 6.7.3-8 and 6.7.4-0 I get

>convert testgraph.pdf test.png

Thanks Magick, it is indeed a regression bug in GS 8.70, in GS 8.65, it works:

When I convert this PDF image
http://fkurth.de/uwest/bugreports/Resistance-Network.pdf
to another format like a PNG using ImageMagick 6.5.7-3 on Windows XP:

convert -define pdf:use-cropbox=true pdf:Resistance-Network.pdf png:testa.png

I get these errors:

Many thanks for the prompt reply. This was indeed my problem.

I'm using Ghostscript 8.62 and ImageMagick 4.6.1-1.

When I convert this file:
http://fkurth.de/uwest/bugreports/test2.eps
with the command
convert test2.eps test2.jpg
I get this result:
http://fkurth.de/uwest/bugreports/test2.jpg
You can see that the image gets aliased.

But when I convert it to ...

We grab the bounding box properly but unlike Postscript we cannot yet determine how to translate the PDF as required by the bounding box (for your image about -50,-50). For Ghostscript we inject the Postscript statement "-50, -50 translate". It may take awhile before we properly fix this problem ...
