How to install imagemagick

Omeka Classic
1

Greetings,

I have Omeka Classic v.3.1.2 installed on Debian 12, what is the correct way to install ImageMagick?, so that it shows thumbnail images of the PDF files I uploaded.

Omeka Classic throws the following message:

“The ImageMagick directory path has not been defined. No derived images will be created. If you want Omeka to create derived images, please add the path in settings.”

Thanks for the help.

Hi @imercador ,

You might want to verify that it’s not installed first, and if it is, just verify the path in the Omeka settings.

If it’s not installed you can follow a guide like this, which shows 2 ways to to install it.

The last step, specific to PDF thumbnail generation, is to change the security policy so imagemagick can read PDF files: Imagemagick error when trying to generate pdf thumbnails - #4 by marius

Greetings,

I followed the steps you recommended to correctly install ImageMagick, but when I loaded a pdf file, it showed me the same message again:

“The ImageMagick directory path has not been defined. No derived images will be created. If you want Omeka to create derived images, please add the path in settings.”

Is there any way to solve this problem?

Thanks again.

Did you also modify the policy.xml file as described in this forum post so that imagemagick can read PDF files? Imagemagick error when trying to generate pdf thumbnails - #4 by marius

Greetings,

I was able to solve the problem. After having successfully installed ImageMagick, I should have entered Settings and in the ImageMagick directory path option indicate the correct path /usr/bin then Test and finally Save.

Thanks
