    wkhtmltopdf

    wkhtmltopdf

    Convert HTML to PDF using Webkit (QtWebKit)

    wkhtmltopdf and wkhtmltoimage are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the Qt WebKit rendering engine. These run entirely "headless" and do not require a display or display service. There is also a C library, if you're into that kind of thing. The file pdf.h contains a fairly high level and stable pure c binding to wkhtmltopdf. These binding are well documented and do not depend on QT. Using this is the recommended way of interfacing with the PDF portion of libwkhtmltox. The rest of the headers directly exposes the C++ QT dependent class used internally by wkhtmltopdf and wkhtmltoimage. 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.
