PLEASE NOTE:
The media filters have changed by incorporating the use of ImageMagick and Ghostscript. See the link below for details about enabling media filters.
Requirements
Check the following and then return.
http://wiki.lib.sun.ac.za/index.php/SUNScholar/Install_DSpace/S03#Step_3.2
Step 1 - Login to the server
http://wiki.lib.sun.ac.za/index.php/SUNScholar/Prepare_Ubuntu/S01
Complete ALL of the following as the "dspace" user!
Step 2 - Install the Ubuntu software packages
Type the following:
sudo apt-get install imagemagick ghostscript
Step 2 - Configuration
Check the value for thumbnail.maxwidth and that it corresponds to the size you want for preview images for the UI.
Edit the "dspace.cfg" file.
nano $HOME/source/config/dspace.cfg
Search for the following and modify.
# maximum width and height of generated thumbnails thumbnail.maxwidth = 160 thumbnail.maxheight = 160
Step 3 - Rebuild DSpace
Step 4 - Test the media filers
Type the following to test. Select an item that has pdf files attached and use it as replacement for "123456789/29097".
$HOME/bin/dspace filter-media -n -v -i 123456789/29097
Step 7 - Create new thumbnails
The script is configured to do 1000 items at a time only. This saves on memory and CPU time. Therefore on a large system you may need to run the script several times. Also make sure that the dspace user has full read/write access to all items in the assetstore folders.
$HOME/bin/dspace filter-media -n -v -f -m 1000 -p "PDF Thumbnail"
Step 8 - Add a daily admin task
See: http://wiki.lib.sun.ac.za/index.php/SUNScholar/Daily_Admin. Check the "filter-media" options!
