Hi Tim, I use DSpace 6.3. Sorry for late response but I was testing my website: when I removed ImageMagick Image Thumbnail and ImageMagick PDF Thumbnail filters and got back to default DSpace ones, I restored text extraction functionality. Maybe something was set up incorrectly (apart from those two ImageMagick filters, I had additional settings enabled as org.dspace.app.mediafilter.ImageMagickThumbnailFilter.flatten, org.dspace.app.mediafilter.ImageMagickThumbnailFilter.cmyk_profile, and org.dspace.app.mediafilter.ImageMagickThumbnailFilter.srgb_profile, with according values).
Anyways, the default filters fit the bills. Peter W dniu piątek, 29 marca 2019 19:14:45 UTC użytkownik Tim Donohue napisał: > > Hi Peter, > > You didn't mention what version of DSpace you are using.
