I created a simple service, that applies Quartz Black&Wite filter (the only block in the program) to a currently opened PDF and would like it appear in Services menu in Preview app. I have chosen PDF to get in Preview app, though it does not appear in apps menu (setting Files and Folders didn't work too).
The service in ~Library\Services, it shows up and is checked in Preferences.
Other services though appear correctly (i.e. Finder services).
I have created it this way: chosen to create a Service first, then set to get PDF in Preview.app, then added a Quartz-filter. Saved and opened to add to library.
I have looked through related questions and in general everyone has the same issue, but I haven't found a suitable solution, so maybe someone has an insight on requirements for a service to appear in context or app menu.
