Hi folks I'm trying to generate PDF thumbnails for a repository, and I have followed the instructions at https://wiki.duraspace.org/display/DSDOC18/Configuration#Configuration-XPDFFilter
I've built on a Mac, incorporating the java advanced imaging jars, and uploaded, including the XPDF tools to a Linux box. The error I get from media-filter is as follows: ERROR filtering, skipping bitstream: Item Handle: 123456789/8545 Bundle Name: ORIGINAL File Size: 13249898 Checksum: b0152697cf45c5a396a5f85f21df1979 (MD5) Asset Store: 0 java.io.IOException: Unknown failure while transforming file to preview: no image produced. java.io.IOException: Unknown failure while transforming file to preview: no image produced. at org.dspace.app.mediafilter.XPDF2Thumbnail.getDestinationStream(XPDF2Thumbnail.java:274) at org.dspace.app.mediafilter.MediaFilterManager.processBitstream(MediaFilterManager.java:737) at org.dspace.app.mediafilter.MediaFilterManager.filterBitstream(MediaFilterManager.java:561) at org.dspace.app.mediafilter.MediaFilterManager.filterItem(MediaFilterManager.java:511) at org.dspace.app.mediafilter.MediaFilterManager.applyFiltersItem(MediaFilterManager.java:479) at org.dspace.app.mediafilter.MediaFilterManager.main(MediaFilterManager.java:353) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.dspace.app.launcher.ScriptLauncher.main(ScriptLauncher.java:183) Updating search index: It looks as though, in XPDF2Thumbnail.java, I am ok up to the call to source = ImageIO.read(outf); as the previous logs say 2013-07-23 16:28:13,932 DEBUG org.dspace.app.mediafilter.XPDF2Thumbnail @ DPI: pdfinfo method got dpi=72 for max dim=792 (points, 1/72") 2013-07-23 16:28:13,933 DEBUG org.dspace.app.mediafilter.XPDF2Thumbnail @ Running xpdf command: [/u01/dspace/dspace/bin/xpdf/pdftoppm, -q, -f, 1, -l, 1, -r, 72, /tmp/DSfilt7452068847272888953.pdf, /tmp/prevu8069855567105058459out] 2013-07-23 16:28:14,065 DEBUG org.dspace.app.mediafilter.XPDF2Thumbnail @ PDFTOPPM output is: /tmp/prevu8069855567105058459out-000001.ppm, exists=true Source is null coming out of ImageIO. Just wondering if anyone knows enough about the class to give me any pointers as to why the transform should fail. Thanks very much- I can give more information if it will help!
