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.

To enable, follow the instructions mentioned in the link above.

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

See please note above.

Step 3 - Install the java packages

See please note above.

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 4B

See please note above.

Step 4C

See please note above.

Step 4D

See please note above.

Step 4E

See please note above.

Step 4 - Build and Install

See please note above.

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!
