Reduced Functionality

This version of wkhtmltopdf has been compiled against a version of QT without the wkhtmltopdf patches. Therefore some features are missing, if you need these features please use the static version.

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.

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

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.
