Hello everyone.
I need some help or directions with ImageMagick and mediafilters. We are
running Dspace 5.1 (Mirage 2) on linux. I'm trying to create PDF thumbnails
with ImageMagick media filter.
dspace.cfg:
filter.plugins = PDF Text Extractor, HTML Text Extractor, \
PowerPoint Text Extractor, \
JPEG Thumbnail, \
ImageMagick Image Thumbnail,
ImageMagick PDF Thumbnail, \
Branded Preview JPEG
plugin.named.org.dspace.app.mediafilter.FormatFilter = \
org.dspace.app.mediafilter.ImageMagickImageThumbnailFilter = ImageMagick
Image Thumbnail, \
org.dspace.app.mediafilter.ImageMagickPdfThumbnailFilter = ImageMagick
PDF Thumbnail
filter.org.dspace.app.mediafilter.ImageMagickImageThumbnailFilter.inputFormats
= BMP, GIF, image/png, JPG, TIFF, JPEG, JPEG 2000
filter.org.dspace.app.mediafilter.ImageMagickPdfThumbnailFilter.inputFormats
= Adobe PDF
Additional settings:
thumbnail.maxwidth = 160
thumbnail.maxheight = 160
org.dspace.app.mediafilter.ImageMagickThumbnailFilter.ProcessStarter =
/usr/bin/
org.dspace.app.mediafilter.ImageMagickThumbnailFilter.replaceRegex =
^Generated Thumbnail$
org.dspace.app.mediafilter.ImageMagickThumbnailFilter.bitstreamDescription
= IM Thumbnail
ImageMagick and Ghostscrip is accessible:
[dspace@~]$ which convert
/usr/bin/convert
[dspace@~]$ which ghostscript
/usr/bin/ghostscript
When I'm trying to run it manually:
./dspace filter-media -i 007/11797 -v
I get the following error in dspace log:
2015-04-20 15:59:57,457 WARN org.dspace.core.PluginManager @ Cannot find
named plugin for interface=org.dspace.app.mediafilter.FormatFilter,
name="ImageMagick Image Thumbnail"
And another error in command line:
ERROR: Unknown MediaFilter specified (either from command-line or in
dspace.cfg): 'ImageMagick Image Thumbnail'
Any help or advice appreciated.
Thanks.
