Back to Media Filters

PLEASE NOTE:

The media filters have changed by incorporating the use of ImageMagick and Ghostscript. See the link below for details.

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 3 - Install the java packages

N/A

Step 4 - Configuration

Step 4A

First, be sure there is a 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 4 - Build and Install

N/A

Step 5 - Update dspace rebuild script

See please note above.

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!
