     OPTIONS
          A summary of options is included below.

          --help, -h
               Show this summary of options.

          <input PDF files | - |
               A list of the input PDF files. If you plan to combine these PDFs
               (without using handles) then list files in the order you want
               them combined.  Use - to pass a single PDF into pdftk via stdin.
               Input files can be associated with handles, where a handle is one
               or more upper-case letters:

               <input PDF handle>=<input PDF filename>

               Handles are often omitted.  They are useful when specifying PDF
               passwords or page ranges, later.

               For example: A=input1.pdf QT=input2.pdf M=input3.pdf

          [input_pw <input PDF owner passwords |
               Input PDF owner passwords, if necessary, are associated with
               files by using their handles:

               <input PDF handle>=<input PDF file owner password>

               If handles are not given, then passwords are associated with
               input files by order.

               Most pdftk features require that encrypted input PDF are
               accompanied by the ~owner~ password. If the input PDF has no
               owner password, then the user password must be given, instead.
               If the input PDF has no passwords, then no password should be
               given.

               When running in do_ask mode, pdftk will prompt you for a password
               if the supplied password is incorrect or none was given.

          [<operation> <operation arguments>]
               Available operations are: cat, shuffle, burst, rotate,
               generate_fdf, fill_form, background, multibackground, stamp,
               multistamp, dump_data, dump_data_utf8, dump_data_fields,
               dump_data_fields_utf8, dump_data_annots, update_info,
               update_info_utf8, attach_files, unpack_files. Some operations
               takes additional arguments, described below.

               If this optional argument is omitted, then pdftk runs in 'filter'
               mode.  Filter mode takes only one PDF input and creates a new PDF
               after applying all of the output options, like encryption and
               compression.

             cat [<page ranges>]
                  Assembles (catenates) pages from input PDFs to create a new
                  PDF. Use cat to merge PDF pages or to split PDF pages from
                  documents. You can also use it to rotate PDF pages. Page order
                  in the new PDF is specified by the order of the given page
                  ranges. Page ranges are described like this:

                  <input PDF handle>[<begin page number>[-<end page
                  number>[<qualifier>]]][<page rotation>]

                  Where the handle identifies one of the input PDF files, and
                  the beginning and ending page numbers are one-based references
                  to pages in the PDF file.  The qualifier can be even or odd,
                  and the page rotation can be north, south, east, west, left,
                  right, or down.

                  If a PDF handle is given but no pages are specified, then the
                  entire PDF is used. If no pages are specified for any of the
                  input PDFs, then the input PDFs' bookmarks are also merged and
                  included in the output.

                  If the handle is omitted from the page range, then the pages
                  are taken from the first input PDF.

                  The even qualifier causes pdftk to use only the even-numbered
                  PDF pages, so 1-6even yields pages 2, 4 and 6 in that order.
                  6-1even yields pages 6, 4 and 2 in that order.

                  The odd qualifier works similarly to the even.

                  The page rotation setting can cause pdftk to rotate pages and
                  documents.  Each option sets the page rotation as follows (in
                  degrees): north: 0, east: 90, south: 180, west: 270, left:
                  -90, right: +90, down: +180. left, right, and down make
                  relative adjustments to a page's rotation.

                  If no arguments are passed to cat, then pdftk combines all
                  input PDFs in the order they were given to create the output.

                  NOTES:
                  * <end page number> may be less than <begin page number>.
                  * The keyword end may be used to reference the final page of a
                  document instead of a page number.
                  * Reference a single page by omitting the ending page number.
                  * The handle may be used alone to represent the entire PDF
                  document, e.g., B1-end is the same as B.
                  * You can reference page numbers in reverse order by prefixing
                  them with the letter r. For example, page r1 is the last page
                  of the document, r2 is the next-to-last page of the document,
                  and rend is the first page of the document. You can use this
                  prefix in ranges, too, for example r3-r1 is the last three

                  pages of a PDF.

                  Page Range Examples without Handles:
                  1-endeast - rotate entire document 90 degrees
                  5 11 20 - take single pages from input PDF
                  5-25oddwest - take odd pages in range, rotate 90 degrees
                  6-1 - reverse pages in range from input PDF

                  Page Range Examples Using Handles:
                  Say A=in1.pdf B=in2.pdf, then:
                  A1-21 - take range from in1.pdf
                  Bend-1odd - take all odd pages from in2.pdf in reverse order
                  A72 - take a single page from in1.pdf
                  A1-21 Beven A72 - assemble pages from both in1.pdf and in2.pdf
                  Awest - rotate entire in1.pdf document 90 degrees
                  B - use all of in2.pdf
                  A2-30evenleft - take the even pages from the range, remove 90
                  degrees from each page's rotation
                  A A - catenate in1.pdf with in1.pdf
                  Aevenwest Aoddeast - apply rotations to even pages, odd pages
                  from in1.pdf
                  Awest Bwest Bdown - catenate rotated documents

             shuffle [<page ranges>]
                  Collates pages from input PDFs to create a new PDF.  Works
                  like the cat operation except that it takes one page at a time
                  from each page range to assemble the output PDF.  If one range
                  runs out of pages, it continues with the remaining ranges.
                  Ranges can use all of the features described above for cat,
                  like reverse page ranges, multiple ranges from a single PDF,
                  and page rotation.  This feature was designed to help collate
                  PDF pages after scanning paper documents.

             burst
                  Splits a single input PDF document into individual pages. Also
                  creates a report named doc_data.txt which is the same as the
                  output from dump_data.  If the output section is omitted, then
                  PDF pages are named: pg_%04d.pdf, e.g.: pg_0001.pdf,
                  pg_0002.pdf, etc.  To name these pages yourself, supply a
                  printf-styled format string via the output section.  For
                  example, if you want pages named: page_01.pdf, page_02.pdf,
                  etc., pass output page_%02d.pdf to pdftk.  Encryption can be
                  applied to the output by appending output options such as
                  owner_pw, e.g.:

                  pdftk in.pdf burst owner_pw foopass

             rotate [<page ranges>]
                  Takes a single input PDF and rotates just the specified pages.
                  All other pages remain unchanged.  The page order remains
                  unchaged.  Specify the pages to rotate using the same notation

                                    July 24, 2013

                  as you would with cat, except you omit the pages that you
                  aren't rotating:

                  [<begin page number>[-<end page number>[<qualifier>]]][<page
                  rotation>]

                  The qualifier can be even or odd, and the page rotation can be
                  north, south, east, west, left, right, or down.

                  Each option sets the page rotation as follows (in degrees):
                  north: 0, east: 90, south: 180, west: 270, left: -90, right:
                  +90, down: +180. left, right, and down make relative
                  adjustments to a page's rotation.

                  The given order of the pages doesn't change the page order in
                  the output.

             generate_fdf
                  Reads a single input PDF file and generates an FDF file
                  suitable for fill_form out of it to the given output filename
                  or (if no output is given) to stdout.  Does not create a new
                  PDF.

             fill_form <FDF data filename | XFDF
                  Fills the single input PDF's form fields with the data from an
                  FDF file, XFDF file or stdin. Enter the data filename after
                  fill_form, or use - to pass the data via stdin, like so:

                  pdftk form.pdf fill_form data.fdf output form.filled.pdf

                  If the input FDF file includes Rich Text formatted data in
                  addition to plain text, then the Rich Text data is packed into
                  the form fields as well as the plain text.  Pdftk also sets a
                  flag that cues Reader/Acrobat to generate new field
                  appearances based on the Rich Text data.  So when the user
                  opens the PDF, the viewer will create the Rich Text appearance
                  on the spot.  If the user's PDF viewer does not support Rich
                  Text, then the user will see the plain text data instead.  If
                  you flatten this form before Acrobat has a chance to create
                  (and save) new field appearances, then the plain text field
                  data is what you'll see.

                  Also see the flatten and need_appearances options.

             background <background PDF filename | -
                  Applies a PDF watermark to the background of a single input
                  PDF.  Pass the background PDF's filename after background like
                  so:

                  pdftk in.pdf background back.pdf output out.pdf

                                    July 24, 2013

                  Pdftk uses only the first page from the background PDF and
                  applies it to every page of the input PDF.  This page is
                  scaled and rotated as needed to fit the input page.  You can
                  use - to pass a background PDF into pdftk via stdin.

                  If the input PDF does not have a transparent background (such
                  as a PDF created from page scans) then the resulting
                  background won't be visible -- use the stamp operation
                  instead.

             multibackground <background PDF filename | -
                  Same as the background operation, but applies each page of the
                  background PDF to the corresponding page of the input PDF.  If
                  the input PDF has more pages than the stamp PDF, then the
                  final stamp page is repeated across these remaining pages in
                  the input PDF.

             stamp <stamp PDF filename | -
                  This behaves just like the background operation except it
                  overlays the stamp PDF page on top of the input PDF document's
                  pages.  This works best if the stamp PDF page has a
                  transparent background.

             multistamp <stamp PDF filename | -
                  Same as the stamp operation, but applies each page of the
                  background PDF to the corresponding page of the input PDF.  If
                  the input PDF has more pages than the stamp PDF, then the
                  final stamp page is repeated across these remaining pages in
                  the input PDF.

             dump_data
                  Reads a single input PDF file and reports its metadata,
                  bookmarks (a/k/a outlines), page metrics (media, rotation and
                  labels), data embedded by STAMPtk (see STAMPtk's embed option)
                  and other data to the given output filename or (if no output
                  is given) to stdout.  Non-ASCII characters are encoded as XML
                  numerical entities.  Does not create a new PDF.

             dump_data_utf8
                  Same as dump_data excepct that the output is encoded as UTF-8.

             dump_data_fields

                  statistics to the given output filename or (if no output is

             dump_data_annots
                  This operation currently reports only link annotations.  Reads
                  a single input PDF file and reports annotation information to
                  the given output filename or (if no output is given) to
                  stdout. Non-ASCII characters are encoded as XML numerical
                  entities. Does not create a new PDF.

             update_info <info data filename | -
                  Changes the bookmarks and metadata in a single PDF's Info
                  dictionary to match the input data file. The input data file
                  uses the same syntax as the output from dump_data. Non-ASCII
                  characters should be encoded as XML numerical entities.

                  This operation does not change the metadata stored in the
                  PDF's XMP stream, if it has one. (For this reason you should
                  include a ModDate entry in your updated info with a current
                  date/timestamp, format: D:YYYYMMDDHHmmSS, e.g. D:201307241346
                  -- omitted data after YYYY revert to default values.)

                  For example:

                  pdftk in.pdf update_info in.info output out.pdf

             update_info_utf8 <info data filename | -
                  Same as update_info except that the input is encoded as UTF-8.

             attach_files <attachment filenames | PROMPT> [to_page
                  Packs arbitrary files into a PDF using PDF's file attachment
                  features. More than one attachment may be listed after
                  attach_files. Attachments are added at the document level
                  unless the optional to_page option is given, in which case the
                  files are attached to the given page number (the first page is
                  1, the final page is end). For example:

                  pdftk in.pdf attach_files table1.html table2.html to_page 6
                  output out.pdf

             unpack_files
                  Copies all of the attachments from the input PDF into the
                  current folder or to an output directory given after output.
                  For example:

                  pdftk report.pdf unpack_files output ~/atts/

                  or, interactively:

                  pdftk report.pdf unpack_files output PROMPT

          [output <output filename | - |
               The output PDF filename may not be set to the name of an input
               filename. Use - to output to stdout.  When using the dump_data

               When using the unpack_files operation, use output to set the name
               of an output directory.  When using the burst operation, you can
               use output to control the resulting PDF page filenames (described
               above).

          [encrypt_40bit | encrypt_128bit]
               If an output PDF user or owner password is given, output PDF
               encryption strength defaults to 128 bits.  This can be overridden
               by specifying encrypt_40bit.

          [allow <permissions>]
               Permissions are applied to the output PDF only if an encryption
               strength is specified or an owner or user password is given.  If
               permissions are not specified, they default to 'none,' which
               means all of the following features are disabled.

               The permissions section may include one or more of the following
               features:

          [owner_pw <owner password | PROMPT>]

          [user_pw <user password | PROMPT>]
               If an encryption strength is given but no passwords are supplied,
               then the owner and user passwords remain empty, which means that
               the resulting PDF may be opened and its security parameters

          [compress | uncompress]
               These are only useful when you want to edit PDF code in a text
               editor like vim or emacs.  Remove PDF page stream compression by
               applying the uncompress filter. Use the compress filter to
               restore compression.

          [flatten]
               Use this option to merge an input PDF's interactive form fields
               (and their data) with the PDF's pages. Only one input PDF may be
               given. Sometimes used with the fill_form operation.

          [need_appearances]
               Sets a flag that cues Reader/Acrobat to generate new field
               appearances based on the form field values.  Use this when
               filling a form with non-ASCII text to ensure the best
               presentation in Adobe Reader or Acrobat.  It won't work when
               combined with the flatten option.

          [keep_first_id | keep_final_id]
               When combining pages from multiple PDFs, use one of these options
               to copy the document ID from either the first or final input
               document into the new output PDF. Otherwise pdftk creates a new
               document ID for the output PDF. When no operation is given, pdftk
               always uses the ID from the (single) input PDF.

          [drop_xfa]
               If your input PDF is a form created using Acrobat 7 or Adobe
               Designer, then it probably has XFA data.  Filling such a form
               using pdftk yields a PDF with data that fails to display in
               Acrobat 7 (and 6?).  The workaround solution is to remove the
               form's XFA data, either before you fill the form using pdftk or
               at the time you fill the form. Using this option causes pdftk to
               omit the XFA data from the output PDF form.

               This option is only useful when running pdftk on a single input
               PDF.  When assembling a PDF from multiple inputs using pdftk, any
               XFA data in the input is automatically omitted.

          [drop_xmp]
               Many PDFs store document metadata using both an Info dictionary
               (old school) and an XMP stream (new school).  Pdftk's update_info
               operation can update the Info dictionary, but not the XMP stream.
               The proper remedy for this is to include a ModDate entry in your
               updated info with a current date/timestamp. The date/timestamp
               format is: D:YYYYMMDDHHmmSS, e.g. D:201307241346 -- omitted data
               after YYYY revert to default values. This newer ModDate should
               cue PDF viewers that the Info metadata is more current than the
               XMP data.

               Alternatively, you might prefer to remove the XMP stream from the
               PDF altogether -- that's what this option does.  Note that
               objects inside the PDF might have their own, separate XMP
               metadata streams, and that drop_xmp does not remove those.  It
               only removes the PDF's document-level XMP stream.

          [verbose]
               By default, pdftk runs quietly. Append verbose to the end and it
               will speak up.

          [dont_ask | do_ask]
               Depending on the compile-time settings (see ASK_ABOUT_WARNINGS),
               pdftk might prompt you for further input when it encounters a
               problem, such as a bad password. Override this default behavior
               by adding dont_ask (so pdftk won't ask you what to do) or do_ask
               (so pdftk will ask you what to do).

               When running in dont_ask mode, pdftk will over-write files with
               its output without notice.
