--------------------------------

             Summary: Tika App -z should extract PDF inline images by default
                 Key: TIKA-2374
                 URL: https://issues.apache.org/jira/browse/TIKA-2374
             Project: Tika
          Issue Type: Improvement
          Components: cli
    Affects Versions: 1.14
            Reporter: Nick Burch


As discussed on dev@ - If you use the Tika App with the default config and the 
{{-z}} extract option, it will extract embedded resources, except PDF inline 
images. This is unexpected for new users, who won't know that they'd need to 
pass in a custom config with the {{extractInlineImages}} PDF parser option set

If the user passes in an explicit config to the app, we should respect that. 
However, if they don't pass one in and take the default, the -z option should 
(but only that one) enable whatever options are needed to make extraction work 
properly + fully (currently just {{extractInlineImages}})

If possible/easy, the -z option should print out some info to let affected 
users know that the default config was tweaked to give extra embedded resources
