I need to create a .jpg preview of an Indesign document, however I don't have all the fonts installed on the system running Indesign server, is there a way to generate a preview without having all the fonts Installed? Someone told me that there might exist a preview in the Indesign document, can I extract that somehow?
But only if the document contains thumbnails to begin with - it's a Preferences setting. Check this thread for a discussion of an InDesign Server script: Extract indesign preview
I also wrote an external program, which does not need running from within InDesign, but cannot locate that particular thread. (FYI it's a Windows console program. It may or may not work with current versions of InDesign - Adobe has a habit of changing such details at a whim )
