Passing -geometry results in a black image

[jessp0110]

Hello dev team,

On:
# cat /etc/issue
Ubuntu 12.04.3 LTS \n \l

Using both Version: ImageMagick 6.6.9-7 which is the official version in the repos, as well as 6.5.1-2 Q16, this command fails:
# /home/jess/bin/convert -limit memory 512 -density 400x400 -geometry $ANY_NUMBER /path/to/source.pdf /tmp/jessport1.jpg

However, this one results in a successful conversion:
# /usr/bin/convert -limit memory 512 -density 400x400 /path/to/source.pdf /tmp/jessport0.jpg

On FC11, using 6.5.1-2 the first command also completes successfully.

Please let me know if you need an strace output or want me to try to use a debug binary with control outputs.
I can also provide the source file, I don't see an option to attach a file here though..

Thank you in advance,

Perhaps -density and -geometry are competing. You should not need both. Normally one just uses -density.

Hello,

In the man page I see:
-geometry geometry preferred size or location of the image

So, I am not quite sure why you say it will take no affect but regardless, why does it cause this result? and why doesn't it on FC?
Thanks,

I have never seen -geometry used that way. But a quick test does show it has an effect on the size of the pdf using IM 6.8.7.3. Normally it is just a setting for use with -composite. But as a setting, I suppose it could affect the size of a pdf when used before the reading of the pdf.

Hi,

I am using this as part of a pretty extensive conversion engine which I would really prefer not to change at the moment.
My question is still valid, I think: why does it work well on FC with the same exact IM version?

[fmw42]

What is FC? I suspect that there may be issues with the version of IM that you are using that fails.

Perhaps different versions of Ghostscript.

[jessp0110]

FC is Fedora Core.
I tried using two versions as stated in my original post. Both fail the same way.

What about the Ghostscript version on the various computers

Ghostscript versions are the same in both.
Thanks,
