General :: ImageMagick Command Sometimes Fails?
May 5, 2011
I have an ImageMagick command that is something like this:
convert "/path/to/photo" -set comment "(c) my company" -resize WxH miff:- | composite -dissolve 30 -geometry +40+138 -quality 80 "/path/to/logo.miff" - jpeg:"/path/to/photo_for_public"
Directory /path/to is mounted over NFS (same network). Some options of fstab that might be helpful:
Both rsize and wsize are 3kB
hard,proto=tcp,timeo=600,retrans=2
Sometimes the imagemagick command fails and produces no file (/path to/photo_for_public might not emerge after command execution). Files might be from 100kB to 10MB. We usually re-run the command for files not generated. Sometimes it fails even twice, so we do it third time (hilariously funny, but even a third run can fail).
Are there any thoughts what may be wrong with my photo-processing setup?

To take a screenshot(or partial screenshot), I use to use the command-line, type "import <filename>.png" and then "alt-tab" away from the console (for me, xterm) and then (usually) select a part of the webpage showing up on the browser. However, I find in my modern X-window installations (I use osuse and slackware, with several window managers: xfce, icewm and awesome) the alt-tabbing bit doesn't work any more.To get by, I have to reduce the size of the console so that the bit I want to capture is visible as I write the import commandI figure this is an X problem, but it could also be an imagemagick problem (on that subject, I think I'm going to try out graphicsmagick soon)

I wrote a simple command line script which is suppose to take my screenshot every 5 minutes.(using ImageMagick's "import" program)
Here is the script (shottr.sh):
This is working fine if I execute by hand i.e:
The script itself is being executed (I hear a voice saying: "Screenshot") but the actual screenshot is not taken.
Be assured that it is NOT permission issue (I placed a simple "touch" invocation and file was created)
May be if it's run from cron...it doesn't have a "window" so it can't take a screenshot from nowhere? If that is the case, then how can I workaround it?

I have a custom command I've made to quickly shut down all of my xen instances.
Code:
[root@LCENT02 ~]# virtdown
-bash: syntax error near unexpected token `2'
As you can see it fails when I try to run it on the command line. It is stored in an ~/.env file in my home directory. What is odd to me is if I open the .env file and copy the command from there and paste it into the command line, it does actually work!
Code:
[root@LCENT02 ~]# for i in `virsh list | grep -v -e Id -e --- -e Domain-0 | awk '{print $1}'`; do virsh shutdown $i; done
Domain 1 is being shutdown
Domain 2 is being shutdown
Domain 3 is being shutdown
And this is how I have the command entered into my .env file:
Code:
alias virtdown="for i in `virsh list | grep -v -e Id -e --- -e Domain-0 | awk '{print $1}'`; do virsh shutdown $i; done
Why would this command work if you paste it onto the command line but not use the custom command virtdown?

while installing ImageMagick on my i686-pc-linux gnu, everything seems to go fine when i put ./configure --with-modules in action. however, after this, as soon as i execute "make"
it gives loads of error as shown below:
"make all-am
make[1]: Entering directory `/home/vijitkarma/ImageMagick-6.6.2-2'
CC magick/magick_libMagickCore_la-animate.lo
make[1]: Leaving directory `/home/vijitkarma/ImageMagick-6.6.2-2'

The dd commad fails here saying its truncating if I try same command with less value for seek it works dd if=/dev/zero of=/var/images/abc.img bs=1M count=0 seek=2088960
0+0 records in
0+0 records out
0 bytes (0 B) copied, 2.1e-05 seconds, 0.0 kB/s
Whats the reason behind this and how can this be solved ? Note that there is 3.9T available on disk for the above commands to execute.

I've successfully mounted a network share with mount.cifs for the past 2 years using fstab with credfile.
[Code]....
Yesterday I moved this system to a new datacenter, but did not alter fstab or the credfile. The //server/share directory has IP rules in place, but this was updated with the new system IP while we moved the system. Now, I am mysteriously unable to automount //server/share. The local error is 13 (permission denied). The Windows server we are mounting returned a code that is defined as "username is valid but password is incorrect" Again - no changes (content or permissions) were made to my credfile or fstab entry. I've restarted netfs a few times, including rebooting the system twice. What is baffling is I can successfully mount //server/share via command line: Code: mount -t cifs //server/share /mnt/mycooldir -o username=foobar,password=1234
The username and passwords are identical in credfile and the mount options - I copied & pasted username / password from the credfile itself.

I downloaded, configured and installed ImageMagic-6.7 without too much trouble.
I'm trying to install the perl module Image::Magick, and using MCPAN just errors out big time.
I read in the docs for installing ImageMagic, that I need to edit the Makefile.PL in the PerlMagick directory before I can do a make / make install.
I'm supposed to change the LIBS and INC, but I have no idea what I'm supposed to change them to? Do I just add to what's there? Where do I find the values to add/change to?

the output looks like this:
Why is the first page bigger then the others in the PDF? The original JPEGs were all the same size!

I have tried every variation I can think of to get an 'at' to rm a file after a certain amount of time.
echo 'rm -f /var/www/media/images/tempProducts/XYZ.png' | at now + 2 minutes
In php:
$apCommand = "echo 'rm -f " . $sTempName . "' | at now + 2 minutes";
exec ($apCommand);
I have:
- pasted the command into the command line as root and it works fine so it seems to be rights related -- rm gets scheduled and the file gets deleted after 2 minutes
- tried every variation of sudo within the statement including making sure that apache is listed in sudoers
- chmod to 777
- chown to apache
The rm command does get scheduled into the 'at' queue but the rm never removes the file.
at -c (without adding sudo to the 'at' statement)
#!/bin/sh
# atrun uid=48 gid=48
# mail apache 0
umask 22

On Red Hat Enterprise Linux Server release 5.4, I enter the command:net time set -I 192.59.196.66Where 192.59.196.66 is the IP address of a Windows Server 2008 time serverThe response is:/bin/date 071218072010.20 failed. Error was (Success)The actual clock time does not get updated. However, evidently it did really communicate with the time server on 192.59.196.66, because the value in the response 071218072010.20 does correspond to the time on the time server, albeit in the somewhat bizarre format MMDDHHMMYYYY.SS.

I'm attempting to install ImageMagick on my shiny new CentOS 5 server, but it wants to install a bunch of X libs and ALSA to get that to run.
I don't really want sound software and X installed. I see there is a configure option to install --without-x.Are there any alternatives to compiling from source? Any sort of rpm you know of that I am not seeing?

Ubuntu Server 8.04. I have 2 servers in the same rack, on the same subnet, using the same DNS servers and build with the same media. On one of them the following command fails
Code:
apt-get install squid
On the other on the package was installed with out any problems. I have checked the /etc/apt/sources.list files and they are identical. Actually, it could not find mutt either.

Having an odd problem running a mysqldump via crontab. I have the script running on other servers and they work fine, so not sure how to actually troubleshoot, but the script looks like the following;
If I run it as a cronjob as root, it finishes in a second and a 20k file is there. If I run it from the command line as root it does the backup (takes a few minutes) but does complete the backup and can be unzipped and read successfully.

I've writte a small Munin plugin using python, which basically runs a shell command, and write the output to a file. For some reason the script fail quite often, and it seems to be failing at the "commands.getoutput" statement. This is what's leading up to that statement:

what the command is for the System Tray, so thought I'd ask here. Note I am not asking how to put a system tray on the panel - I know I can add a notification area, but when I reboot there will be 2 of them, so this is not what I want.
I just need to be able to initialise it when it fails to load. Since my upgrade to Lucid, this has happened a couple of times, so expect it will happen again soon enough.

"/usr/lib/ruby/1.8/i486-linux/RMagick2.so: This installation of RMagick was configured with ImageMagick 6.5.1 but ImageMagick 6.5.8-10 is in use. (RuntimeError)".
So, I am trying to install ImageMagick 6.5.1. But it gives me error like:

I need to get imagemagick on a Debian Lenny up from the lowly 6.3.9 version up to 6.4.9, I have looked it up, but can't get brief details on this ... if I just apt-get install, well I get the older version. Do I have to come up with my own deb package?

I have script that I wish to distribute to a small group that requires ImageMagick, but many in the group don't have ImageMagick installed. I'm not really in a position where by I can install ImageMagick on all the groups machines, and my knowledge of compiling is pretty restricted to ./configure; make; make install. Is it possible to compile ImageMagick (or indeed any other program) into a single binary without any external dependencies? I believe to accomplish this I provide ./configure with the following arguments:

I have a folder that over 70,000 images (within it is a complex hierarchy of subfolders). Of these 70,000 images I assume that I only have ~10,000 unique images; the rest are copies that have been resized. I would like to somehow delete all of the resized copies of the larger originals and remove them, keeping only the original image.
Is there a way to use imagemagick (or any other application) to scan this folder recursively and determine which files may be (resized) copies?

I have images in jpg format
Code:
CIMG0100.jpg
...
...
CIMG0131.jpg
I used imagemagick to convert the files to gif with the following command
Code:
for i in {100..131}; do convert CIMG0$i.jpg CIMG0$i.gif; done # works
This worked like expected, but when afterwards I wanted to scale the images
Code:
for i in {100..131}; do convert -scale 25% CIMG00$i.gif CIMG00$i_scaled.gif; done # works not it seems the system is working for about half a minute, but I get no output. The single command
Code:
convert -scale 25% CIMG100.gif CIMG100_scaled.gif # works
works as expected and gives me a scaled image. What does the convert command do in the second case? is the for-loop wrong?

I can't find the imagemagick package in the repositories. Anybody knows where I could find a binary for that SW? I tried to install from source but failed... Everything seemed fine up to when I tried "sudo make install", and there I got lots of errors. When i try to run any command, it does not find the libraries..
