PDF/DOC Thumbnails

[jimmykirk]

I understand that the conversion for documents is as follows:

Upload Word Doc >> Transform to PDF >> Transform to PNG thumbnail.

Upload PDF >> Transform to PNG thumbnail

I can preview my documents (XLS, DOC, PDF) and search the contents of them. However, thumbnails are not working for PDF, DOC, XLS. Thumbnails work for JPG/GIF/PNG/ETC.

I have installed SWFTOOLS 0.9.x and ImageMagick 6.6.1-5.x86_64 from source. I have also installed XPDF separately.

Here is my catalina.out when I upload a PDF…

Any ideas?

Look at http://wiki.alfresco.com/wiki/Installing_Alfresco_components#Installing_SWFTools.

If you encounter issues with the snapshot that you have installed, please swap out the version you are using as a first step in troubleshooting.

So try installing a different SWFTools release and see if this helps.

Weird. I installed the one out of the wiki…

Swftools-centos54-x86_64.tar.gz

It was built for my distro. Maybe I can try another.

Then again, I can preview PDFs fine. Is swftools even used in the conversion of PDF to thumbnails? I had read elsewhere that ImageMagick should handle this.
