Hi All,
I've found a similar situation with 1.8.2 and the problem still is with the
pdftoppm tool when extract the PDF's thumbnail, the tool has changed the output
file naming schema.
In the logs (in debug mode) throws this:
2012-06-20 12:54:21,219 DEBUG org.dspace.app.mediafilter.XPDF2Thumbnail @ DPI:
pdfinfo method got dpi=56 for max dim=1026 (points, 1/72")
2012-06-20 12:54:21,219 DEBUG org.dspace.app.mediafilter.XPDF2Thumbnail @
Running xpdf command: [/usr/bin/pdftoppm, -q, -f, 1, -l, 1, -r, 56,
/tmp/DSfilt2572793846402123318.pdf, /tmp/prevu6465374009455317236out]
2012-06-20 12:54:21,606 DEBUG org.dspace.app.mediafilter.XPDF2Thumbnail @
PDFTOPPM output is: /tmp/prevu6465374009455317236out-000001.ppm, exists=false
2012-06-20 12:54:21,606 ERROR org.dspace.app.mediafilter.XPDF2Thumbnail @
Unable to delete file
And DSpace is looking for a file with the name
prevu6465374009455317236out-000001.ppm but pdftoppm created this file
prevu6465374009455317236out-001.ppm hence the file not found exception.
I've fixed with a script that wraps the pdftoppm tool, and replaced the
xpdf.path.pdftoppm parameter in dspace.cfg to point to this script.
In dspace.cfg I replaced this line:
xpdf.path.pdftoppm = /usr/bin/pdftoppm
With this:
xpdf.path.pdftoppm = /dspace/bin/pdftoppm.sh
And the script is in /dspace/bin/pdftoppm.sh
Please change the path to pdftoppm according to yours.
START SCRIPT --------------------------
#!/bin/sh
# Enrique Martinez
# Para corregir el nombre de archivo de la extracion de la caratula.
/usr/bin/pdftoppm $1 $2 $3 $4 $5 $6 $7 $8 $9
CONVERTRESULT=$?
SOURCEFILE=$9-*.ppm
TARGETFILE=$9-000001.ppm
for file in $SOURCEFILE; do mv $file $TARGETFILE; exit; done
return $CONVERTRESULT
END SCRIPT --------------------------
Hope this helps,
Enrique Martínez

Asunto: Re: [Dspace-tech] Thumbnail Priview. in 1.6.2
Hi Kirti:
Not sure if you are having other problems, but I did want to clarify how
MediaFilter works.
It is a general set of tools for operating on your bitstream content, and the
primary use for most people is to extract text (for indexing) from PDFs Word
files etc, not to produce thumbnails of those formats.
These functions are configured in dspace.cfg (search for 'mediafilter'
properties) - and each 'filter' is given a list of formats to process. It
further optimizes its work by not recreating a derivative (i.e. the text file,
or thumbnail, etc) if it already exists - that is the message you are seeing
below (SKIPPED).
Hope this helps,
Richard R
