How do I integrate alfresco-pdf-renderer in the Community Edition 201707GA?

Jump to solution

Hi all,

the release notes for 201707GA of the community edition mention the carve-out of GhostScript and introduction of alfresco-pdf-renderer as a wrapper for PDFium. Installing the new packages as an update on my Tomcat installation on Linux I receive the following error in my log:

 ERROR [org.alfresco.repo.content.transform.pdfrenderer.AlfrescoPdfRendererContentTransformerWorker] [http-apr-8080-exec-33] Alfresco-PDF-Renderer is not available for transformations.
Execution result:
   os:         Linux
   command:    ./alfresco-pdf-renderer --version
   succeeded:  false
   exit code:  1
   out:
   err:        Cannot run program "./alfresco-pdf-renderer": error=2, No such file or directory

I downloaded the linux edition of alfresco-pdf-renderer directly from the maven repository, but do not know how to integrate it. At least adding the two lines

alfresco-pdf-renderer.root=/usr/local/bin
alfresco-pdf-renderer.exe=${alfresco-pdf-renderer.root}/alfresco-pdf-renderer

to my alfresco-global-properties did not change a thing.

I also wonder if I need to provide pdfium somehow. Any help is much appreciated.

Best regards
Johannes

Hi:

I just installed the linux bundle and I can see the alfresco-pdf-renderer in common directory:

cesar@lemmy $ /opt/alfresco52g/common/alfresco-pdf-renderer/alfresco-pdf-renderer -h
Usage: alfresco_pdfium_convert [OPTION] [PDF-FILE] [PNG-FILE]
--width=<width> - override page width in pixels
--height=<height> - override page height in pixels
--maintain-aspect-ratio - Maintain aspect ratio when resizing the page
--allow-enlargement - When maintaining the aspect ratio, allow one parameter to exceed the given height/width
--page=<number> - 0-based page number to be converted (default 0)
--version - Display version information and exit immediately

And in alfresco-global.properties you should have something like the following (this is the default config):

alfresco-pdf-renderer.root=/opt/alfresco52g/common/alfresco-pdf-renderer
alfresco-pdf-renderer.exe=${alfresco-pdf-renderer.root}/alfresco-pdf-renderer

Regards.

For those of us who run non-standard OS (eg: FreeBSD) which doesn't have PDFium available, I've coded up a python wrapper for image magick (which in turn uses ghostscript (I believe from docs) - both still available on FreeBSD).

Alpha code but it works.

See here for details:

GitHub - BambooVolt/alfresco-pdf-renderer-in-python: Provides a wrapper for using ImageMagick(/Ghost... 

Simply drop into the same folder - typically ${alfresco_home}/common/alfresco-pdf-renderer

Then update alfresco-global.properties as below:

alfresco-pdf-renderer.root=/opt/alfresco-community/common/alfresco-pdf-renderer
alfresco-pdf-renderer.exe=${alfresco-pdf-renderer.root}/alfresco-pdf-renderer.py

Remember to enable access by the alfresco user (chown alfresco ....) enable execution on unix (chmod 0500 ...) and update the filename appropriately - note the .py extension here.

Options currently Unimplemented:

--allow-enlargement - to do when time permits

--maintain-aspect-ratio - this appears to "Just Work" at this time

The latest packaging of the docker images will describe the software that is needed.
