Back to Media Filters

Step 1 - Login to the server

http://wiki.lib.sun.ac.za/index.php/SUNScholar/Prepare_Ubuntu/S01

Step 2 - Install the Ubuntu software packages

Type the following: 

sudo apt-get install xpdf poppler-utils jai-core jai-imageio-core

Step 3 - Configuration

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/dspace/source/config/dspace.cfg

Search for the following and modify. 

# maximum width and height of generated thumbnails
        thumbnail.maxwidth= 80
        thumbnail.maxheight = 80

Now, add the absolute paths to the XPDF tools you installed.

See example below. 

xpdf.path.pdftotext = /usr/bin/pdftotext
xpdf.path.pdftoppm  = /usr/bin/pdftoppm
xpdf.path.pdfinfo   = /usr/bin/pdfinfo

Change the MediaFilter plugin configuration to remove the old org.dspace.app.mediafilter.PDFFilter and add the new filters "org.dspace.app.mediafilter.XPDF2Text = PDF Text Extractor" and "org.dspace.app.mediafilter.XPDF2Thumbnail = PDF Thumbnail".

See example below. 

filter.plugins = \
        PDF Text Extractor, \
        PDF Thumbnail, \
        HTML Text Extractor, \
        Word Text Extractor, \
        JPEG Thumbnail
         plugin.named.org.dspace.app.mediafilter.FormatFilter = \
        org.dspace.app.mediafilter.XPDF2Text = PDF Text Extractor, \
        org.dspace.app.mediafilter.XPDF2Thumbnail = PDF Thumbnail, \
        org.dspace.app.mediafilter.HTMLFilter = HTML Text Extractor, \
        org.dspace.app.mediafilter.WordFilter = Word Text Extractor, \
        org.dspace.app.mediafilter.JPEGFilter = JPEG Thumbnail, \
        org.dspace.app.mediafilter.BrandedPreviewJPEGFilter = Branded Preview JPEG
