While on IRC, Beuc suggested that the pdf-filter utility returns an error when using 1) no filter or 2) a non-implemented filter. I thought it was a good idea, so I attach a patch for that feature here.
What is the point of returning an error if no filter is applied? Ideally all the filters that can be specified in the command line options are implemented so, what is the point of returning an error code if a filter is not implemented? -- Jose E.
