unable to create temporary file

[rivarola]

Hello,
First, congratulations for the ImageMagick convert utility, that is very usefull and powerfull.
But today, I'm stuck on a permission problem that occurs when the Alfresco ECM (a Tomcat webapp) is run as service on Windows using a service user that is not Administrator (for security purpose). When the convert utility is run by lauching a system command from the Tomcat service, I get this error :

Code: Select all

Execution result: 
   os:         Windows 7
   command:    [C:\Program Files (x86)\ImageMagick-6.7.1-Q16\convert.exe, C:\work\cecm-trunk\temp\Alfresco\ImageMagickContentTransformerWorker_source_4497324710097173389.pdf, +repage, -auto-orient, -background, white, -alpha, Background, -thumbnail, 160x160^>, -gravity, Center, -crop, 160x160+0+0, -extent, 160x160, -auto-orient, C:\work\cecm-trunk\temp\Alfresco\ImageMagickContentTransformerWorker_target_1294637489384402883.png]

	at org.alfresco.repo.content.transform.magick.AbstractImageMagickContentTransformerWorker.transform(AbstractImageMagickContentTransformerWorker.java:249)

The strange thing is that the C:\work\cecm-trunk\temp\Alfresco\ImageMagickContentTransformerWorker_source_4497324710097173389.pdf file exists and is not empty. The window service user has modification permissions under C:\work\cecm-trunk\temp\.

I've already tried to define the MAGICK_TEMPORARY_PATH dir with a writable folder without success.

I have no problem with image -> image conversion using the same service, and pdf -> image conversion works if I run the service as System user. The problem only occurs with pdf -> image transformation when the service runs as normal user.

Any idea ?

Can you reproduce this with the latest version of ImageMagick?

Yes, I can reproduce it with ImageMagick 6.9.1 :
