it seems that when I upload a pdf to the DAM, it does not generate any thumbnails? Is this correct. I would like to be able to generate jpg thumbnails in the same way as pictures do. Is this possible?
Yes, this is correct, no JPG preview is created for an uploaded PDF. If you click on the PDF icon in the preview pane, you will see a preview version in the annotation window. This would be a nice enhancement.
It is possible to change how PDF files are handled using a contribution <extension target="org.nuxeo.ecm.platform.filemanager.service.FileManagerService" point="plugins">. PDFs could be set to be handled by the Imageplugin by removing the PDF filter from the OfficeFileImporter and adding to the ImagePlugin definition.
