Re: [Dspace-tech] Generate publicly accessible thumbnails of restricted content
I took a look at the ImageMagick media filter code and there is no manipulation of bitstream permissions in the code. The generated thumbnail files are returned. I presume those bitstream permissions are set by default based on a collection policy. I had hoped to recommend that you use the XMLUI item wildcard policy admin tool to clean up the permissions, but that tool does not seem to differentiate bitstreams by bundle. In our instance, we want the thumbnail permissions to match the original permissions. Looking at the following code in MediaFilterManager, there may be a mechanism to override the default permission behavior. https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/java/org/dspace/app/mediafilter/MediaFilterManager.java#L778-L789 Terry On Mon, Mar 30, 2015 at 8:08 PM, euler esne...@seafdec.org.ph wrote: Hi Peter, Is there an escape character at the end of ImageMagick Image Thumbnail? i.e. , \ Did the PDF's get thumbnails generated by Image Magick?
