PLEASE NOTE:
The media filters have changed by incorporating the use of ImageMagick and Ghostscript. See the link below for details.
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 6 - 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!
