Name:
  wkhtmltopdf 0.12.6 (with patched qt)

Synopsis:
  wkhtmltopdf [GLOBAL OPTION]... [OBJECT]... <output file>
  
Document objects:
  wkhtmltopdf is able to put several objects into the output file, an object is
  either a single webpage, a cover webpage or a table of contents.  The objects
  are put into the output document in the order they are specified on the
  command line, options can be specified on a per object basis or in the global
  options area. Options from the Global Options section can only be placed in
  the global options area.

  A page objects puts the content of a single webpage into the output document.

  (page)? <input url/file name> [PAGE OPTION]...
  Options for the page object can be placed in the global options and the page
  options areas. The applicable options can be found in the Page Options and 
  Headers And Footer Options sections.

  A cover objects puts the content of a single webpage into the output document,
  the page does not appear in the table of contents, and does not have headers
  and footers.

  cover <input url/file name> [PAGE OPTION]...
  All options that can be specified for a page object can also be specified for
  a cover.

  A table of contents object inserts a table of contents into the output
  document.

  toc [TOC OPTION]...
  All options that can be specified for a page object can also be specified for
  a toc, further more the options from the TOC Options section can also be
  applied. The table of contents is generated via XSLT which means that it can
  be styled to look however you want it to look. To get an idea of how to do
  this you can dump the default xslt document by supplying the
  --dump-default-toc-xsl, and the outline it works on by supplying
  --dump-outline, see the Outline Options section.

                                      printing the table of contents

Page sizes:
  The default page size of the rendered document is A4, but by using the
  --page-size option this can be changed to almost anything else, such as: A3,
  Letter and Legal.  For a full list of supported pages sizes please see 
  <https://qt-project.org/doc/qt-4.8/qprinter.html#PaperSize-enum>.

  For a more fine grained control over the page size the --page-height and
  --page-width options may be used

Reading arguments from stdin:
  If you need to convert a lot of pages in a batch, and you feel that
  wkhtmltopdf is a bit too slow to start up, then you should try
  --read-args-from-stdin,

  When --read-args-from-stdin each line of input sent to wkhtmltopdf on stdin
  will act as a separate invocation of wkhtmltopdf, with the arguments specified
  on the given line combined with the arguments given to wkhtmltopdf

  For example one could do the following:

  echo "https://qt-project.org/doc/qt-4.8/qapplication.html qapplication.pdf" >> cmds
  echo "cover google.com https://en.wikipedia.org/wiki/Qt_(software) qt.pdf" >> cmds
  wkhtmltopdf --read-args-from-stdin --book < cmds
  
Specifying A Proxy:
  By default proxy information will be read from the environment variables:
  proxy, all_proxy and http_proxy, proxy options can also by specified with the
  -p switch

  <type> := "http://" | "socks5://"
  <serif> := <username> (":" <password>)? "@"
  <proxy> := "None" | <type>? <string>? <host> (":" <port>)?
  
  Here are some examples (In case you are unfamiliar with the BNF):

  http://user:password@myproxyserver:8080
  socks5://myproxyserver
  None
  
Footers And Headers:
  Headers and footers can be added to the document by the --header-* and
  --footer* arguments respectively.  In header and footer text string supplied
  to e.g. --header-left, the following variables will be substituted.

   * [page]       Replaced by the number of the pages currently being printed
   * [frompage]   Replaced by the number of the first page to be printed
   * [topage]     Replaced by the number of the last page to be printed
   * [webpage]    Replaced by the URL of the page being printed
   * [section]    Replaced by the name of the current section
   * [subsection] Replaced by the name of the current subsection
   * [date]       Replaced by the current date in system local format
   * [isodate]    Replaced by the current date in ISO 8601 extended format
   * [time]       Replaced by the current time in system local format
   * [title]      Replaced by the title of the of the current page object
   * [doctitle]   Replaced by the title of the output document
   * [sitepage]   Replaced by the number of the page in the current site being converted
   * [sitepages]  Replaced by the number of pages in the current site being converted
  
  
  As an example specifying --header-right "Page [page] of [topage]", will result
  in the text "Page x of y" where x is the number of the current page and y is
  the number of the last page, to appear in the upper left corner in the
  document.

  Headers and footers can also be supplied with HTML documents. As an example
  one could specify --header-html header.html, and use the following content in
  header.html:

  <!DOCTYPE html>
  <html><head><script>
  function subst() {
      var vars = {};
      var query_strings_from_url = document.location.search.substring(1).split('&');
      for (var query_string in query_strings_from_url) {
          if (query_strings_from_url.hasOwnProperty(query_string)) {
              var temp_var = query_strings_from_url[query_string].split('=', 2);
              vars[temp_var[0]] = decodeURI(temp_var[1]);
          }
      }
      var css_selector_classes = ['page', 'frompage', 'topage', 'webpage', 'section', 'subsection', 'date', 'isodate', 'time', 'title', 'doctitle', 'sitepage', 'sitepages'];
      for (var css_class in css_selector_classes) {
          if (css_selector_classes.hasOwnProperty(css_class)) {
              var element = document.getElementsByClassName(css_selector_classes[css_class]);
              for (var j = 0; j < element.length; ++j) {
                  element[j].textContent = vars[css_selector_classes[css_class]];
              }
          }
      }
  }
  </script></head><body style="border:0; margin: 0;" onload="subst()">
  <table style="border-bottom: 1px solid black; width: 100%">
    <tr>
      <td class="section"></td>
      <td style="text-align:right">
        Page <span class="page"></span> of <span class="topage"></span>
      </td>
    </tr>
  </table>
  </body></html>
  
  
  As can be seen from the example, the arguments are sent to the header/footer
  html documents in get fashion.

Outlines:
  Wkhtmltopdf with patched qt has support for PDF outlines also known as book
  marks, this can be enabled by specifying the --outline switch. The outlines
  are generated based on the <h?> tags, for a in-depth description of how this
  is done see the Table Of Contents section. 

  The outline tree can sometimes be very deep, if the <h?> tags where spread to
  generous in the HTML document.  The --outline-depth switch can be used to
  bound this.

Table Of Contents:
  A table of contents can be added to the document by adding a toc object to the
  command line. For example:

  wkhtmltopdf toc https://qt-project.org/doc/qt-4.8/qstring.html qstring.pdf
  
  The table of contents is generated based on the H tags in the input documents.
  First a XML document is generated, then it is converted to HTML using XSLT.

  The generated XML document can be viewed by dumping it to a file using the
  --dump-outline switch. For example:

  wkhtmltopdf --dump-outline toc.xml https://qt-project.org/doc/qt-4.8/qstring.html qstring.pdf
  
  The XSLT document can be specified using the --xsl-style-sheet switch. For
  example:

  wkhtmltopdf toc --xsl-style-sheet my.xsl https://qt-project.org/doc/qt-4.8/qstring.html qstring.pdf
  
  The --dump-default-toc-xsl switch can be used to dump the default XSLT style
  sheet to stdout. This is a good start for writing your own style sheet

  wkhtmltopdf --dump-default-toc-xsl
  The XML document is in the namespace "http://wkhtmltopdf.org/outline" it has a
  root node called "outline" which contains a number of "item" nodes. An item
  can contain any number of item. These are the outline subsections to the
  section the item represents. A item node has the following attributes:

 * "title" the name of the section.
 * "page" the page number the section occurs on.
 * "link" a URL that links to the section.
 * "backLink" the name of the anchor the section will link back to.

  The remaining TOC options only affect the default style sheet so they will not
  work when specifying a custom style sheet.
