# djvused2pdfmark

    npm i -g djvused2pdfmark

When converting a djvu file to a pdf, it's often desirable to transfer

the outline & metadata to the pdf as well.

PDF supports a special `pdfmark` operator that is used for features

like bookmarks & docinfo. Using ghostscript, you can augment an

existing pdf w/ pdfmark commands:

    $ gs -sDEVICE=pdfwrite -dNOPAUSE -dQUIET -dBATCH -sOutputFile=out.pdf input.pdf example.pdfmark

djvused2pdfmark helps you to create such `example.pdfmark` file.

## outline

djvused(1) util exports/imports outlines in the form of sexps:

~~~

(bookmarks

 ("Preface" "#1")

 ("1 Introduction" "#2"

  ("1.1 Foo" "#3")

  ("1.2 Bar" "#4"

   ("1.2.1 start" "#5"))

  ("1.3 Baz" "#6"))

 ("2 Setup" "#7")

 )

~~~

To convert them in pdfmark commands, run:

~~~

$ djvused -e print-outline file.djvu | djvused2pdfmark

[/Page 1 /Title (Preface) /OUT pdfmark

[/Count 3 /Page 2 /Title (1 Introduction) /OUT pdfmark

[/Page 3 /Title (1.1 Foo) /OUT pdfmark

[/Count 1 /Page 4 /Title (1.2 Bar) /OUT pdfmark

[/Page 5 /Title (1.2.1 start) /OUT pdfmark

[/Page 6 /Title (1.3 Baz) /OUT pdfmark

[/Page 7 /Title (2 Setup) /OUT pdfmark

~~~

Only outlines that point to page numbers are supported for now.

## meta

For some reason djvused(1) doesn't use sexps for metadata parts, but a

bizarre list of pairs:

~~~

key1\t"value1"

key2\t"value2"

...

~~~

To convert them to pdf docinfo, pass 'meta' CL argument to

djvused2pdfmark cmd:

~~~

$ djvused -e print-outline file.djvu | djvused2pdfmark meta

[ /Author (John Doe\, Jane Doe)

  /CreationDate (D:19980101000000)

  /Creator (Heaven knows)

  /Producer (A \(custom makefile!)

  /Title (Foo Bar)

  /Subject (An Administrator Guide to Foobar)

  /Keywords (one\, two)

  /ModDate (D:20180101000000)

  /DOCINFO pdfmark

~~~
