       pdfinfo [options] [PDF-file]

       Pdfinfo prints the contents of the 'Info' dictionary (plus
       some  other  useful  information) from a Portable Document
       Format (PDF) file.

       The 'Info' dictionary contains the following values:

              title
              subject
              keywords
              author
              creator
              producer
              creation date
              modification date

       In addition, the following information is printed:

              tagged (yes/no)
              page count
              encrypted flag (yes/no)
              print and copy permissions (if encrypted)
              page size
              file size
              linearized (yes/no)
              PDF version
              metadata (only if requested)

                                                               ()

2 ONFIGURATION_FIL

       Pdfinfo  reads  a configuration file at startup.  It first
       tries to find the user's private config  file,  ~/.xpdfrc.
       If  that  doesn't exist, it looks for a system-wide config
       file, typically /usr/local/etc/xpdfrc (but  this  location
       can  be changed when pdfinfo is built).  See the xpdfrc(5)
       man page for details.

2 OPTIONS

       Many  of  the following options can be set with configura-
       tion file commands.  These are listed in  square  brackets
       with  the  description  of  the corresponding command line
       option.

       -f number
              Specifies the first page to examine.   If  multiple
              pages   are  requested  using  the  "-f"  and  "-l"
              options, the size  of  each  requested  page  (and,
              optionally,  the  bounding boxes for each requested
              page) are printed.  Otherwise,  only  page  one  is
              examined.

       -l number
              Specifies the last page to examine.

       -box   Prints the page box bounding boxes: MediaBox, Crop-
              Box, BleedBox, TrimBox, and ArtBox.

       -meta  Prints  document-level  metadata.   (This  is   the
              "Metadata"  stream  from  the  PDF  file's  Catalog
              object.)

       -enc encoding-name
              Sets the encoding to  use  for  text  output.   The
              encoding-name  must  be defined with the unicodeMap
              command (see xpdfrc(5)).  This defaults to "Latin1"
              (which is a built-in encoding).  [config file: tex-
              tEncoding]

       -opw password
              Specify the owner password for the PDF file.   Pro-
              viding  this will bypass all security restrictions.

       -upw password
              Specify the user password for the PDF file.

       -cfg config-file
              Read config-file in place of ~/.xpdfrc or the  sys-
              tem-wide config file.

       -v     Print copyright and version information.

       -h     Print  usage  information.   (-help  and --help are
              equivalent.)

                                                               ()
