If you experience bugs or want to request new features please visit 
<http://code.google.com/p/wkhtmltopdf/issues/list>, if you have any problems or
comments please feel free to contact me: see 
<http://www.madalgo.au.dk/~jakobt/#about>

===========================> Reduced Functionality <============================
Some versions of wkhtmltopdf are compiled against a version of QT without the
wkhtmltopdf patches. These versions are missing some features, you can find out
if your version of wkhtmltopdf is one of these by running wkhtmltopdf --version
if your version is against an unpatched QT, you can use the static version to
get all functionality.

Currently the list of features only supported with patch QT includes:

 * Printing more then one HTML document into a PDF file.
 * Running without an X11 server.
 * Adding a document outline to the PDF file.
 * Adding headers and footers to the PDF file.
 * Generating a table of contents.
 * Adding links in the generated PDF file.
 * Printing using the screen media-type.
 * Disabling the smart shrink feature of webkit.

==================================> Fork <===================================

This fork of wkhtmltopdf wants to add the functionality to export as SVG files 
any SVG images generated in the rendered web page - as an example, a chart
made with raphaeljs

To be used for http://www.mortgagecalculator3.com/

==================================> 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 content.  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 singe 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 singe webpage into the output document,
the page does not appear in the table of content, 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 content object inserts a table of content 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 content is generated via XSLT which means that it can be styled to
look however you want it to look. To get an aide 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.

=============================> 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>? <sering>? <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 respectfully.  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
 * [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


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:

<html><head><script>
function subst() {
  var vars={};
  var x=document.location.search.substring(1).split('&');
  for (var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
  var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];
  for (var i in x) {
    var y = document.getElementsByClassName(x[i]);
    for (var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
  }
}
</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 Contest 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 Content <==============================
A table of content can be added to the document by adding a toc objectto the
command line. For example:

wkhtmltopdf toc http://doc.trolltech.com/4.6/qstring.html qstring.pdf

The table of content 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 http://doc.trolltech.com/4.6/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 http://doc.trolltech.com/4.6/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://code.google.com/p/wkhtmltopdf/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 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.

===============================> Page Breaking <================================
The current page breaking algorithm of WebKit leaves much to be desired.
Basically webkit will render everything into one long page, and then cut it up
into pages. This means that if you have two columns of text where one is
vertically shifted by half a line. Then webkit will cut a line into to pieces
display the top half on one page. And the bottom half on another page. It will
also break image in two and so on.  If you are using the patched version of QT
you can use the CSS page-break-inside property to remedy this somewhat. There is
no easy solution to this problem, until this is solved try organising your HTML
documents such that it contains many lines on which pages can be cut cleanly.

<http://code.google.com/p/wkhtmltopdf/issues/detail?id=33> and 
<http://code.google.com/p/wkhtmltopdf/issues/detail?id=57>.

=================================> Page sizes <=================================
The default page size of the rendered document is A4, but using this --page-size
optionthis can be changed to almost anything else, such as: A3, Letter and
Legal.  For a full list of supported pages sizes please see 
<http://doc.trolltech.com/4.6/qprinter.html#PageSize-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 to 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 "http://doc.trolltech.com/4.5/qapplication.html qapplication.pdf" >> cmds
echo "cover google.com http://en.wikipedia.org/wiki/Qt_(toolkit) qt.pdf" >> cmds
wkhtmltopdf --read-args-from-stdin --book < cmds

===============================> Static version <===============================
On the wkhtmltopdf website you can download a static version of wkhtmltopdf 
<http://code.google.com/p/wkhtmltopdf/downloads/list>. This static binary will
work on most systems and comes with a build in patched QT.

Unfortunately the static binary is not particularly static, on Linux it depends
on both glibc and openssl, furthermore you will need to have an xserver
installed but not necessary running. You will need to have different fonts
install including xfonts-scalable (Type1), and msttcorefonts.  See 
<http://code.google.com/p/wkhtmltopdf/wiki/static> for trouble shouting.

================================> Compilation <=================================
It can happen that the static binary does not work for your system for one
reason or the other, in that case you might need to compile wkhtmltopdf
yourself.

*GNU/Linux:*

Before compilation you will need to install dependencies: X11, gcc, git and
openssl. On Debian/Ubuntu this can be done as follows:

sudo apt-get build-dep libqt4-gui libqt4-network libqt4-webkit
sudo apt-get install openssl build-essential xorg git-core git-doc libssl-dev

On other systems you must use your own package manager, the packages might be
named differently.

First you must check out the modified version of QT

git clone git://gitorious.org/+wkhtml2pdf/qt/wkhtmltopdf-qt.git wkhtmltopdf-qt
Next you must configure, compile and install QT, note this will take quite some
time, depending on what arguments you use to configure qt

cd wkhtmltopdf-qt
./configure -nomake tools,examples,demos,docs,translations -opensource -prefix ../wkqt
make -j3
make install
cd ..

All that is needed now is, to compile wkhtmltopdf.

git clone git://github.com/antialize/wkhtmltopdf.git wkhtmltopdf
cd wkhtmltopdf
../wkqt/bin/qmake
make -j3

You show now have a binary called wkhtmltopdf in the currently folder that you
can use, you can optionally install it by running

make install
*Other operative systems and advanced features*

If you want more details or want to compile under other operative systemsother
then GNU/Linux, please see
<http://code.google.com/p/wkhtmltopdf/wiki/compilation>.

================================> Installation <================================
There are several ways to install wkhtmltopdf.  You can download a already
compiled binary, or you can compile wkhtmltopdf yourself. On windows the easiest
way to install wkhtmltopdf is to download the latest installer. On linux you can
download the latest static binary, however you still need to install some other
pieces of software, to learn more about this read the static version section of
the manual.

==================================> Examples <==================================
This section presents a number of examples of how to invoke wkhtmltopdf.

To convert a remote HTML file to PDF:

wkhtmltopdf http://www.google.com google.pdf

To convert a local HTML file to PDF:

wkhtmltopdf my.html my.pdf

You can also convert to PS files if you like:

wkhtmltopdf my.html my.ps

Produce the eler2.pdf sample file:

wkhtmltopdf -H  http://geekz.co.uk/lovesraymond/archive/eler-highlights-2008 eler2.pdf

Printing a book with a table of content:

wkhtmltopdf -H cover cover.html toc chapter1.html chapter2.html chapter3.html book.pdf
