What is wkhtmltopdf?

wkhtmltopdf is a tool for converting HTML to PDF. Converts the result rendered by the rendering engine Webkit to PDF.

wkhtmltopdf can be used to create PDF forms. It is convenient to convert a form made of HTML that is published for free on the Web to PDF.

The generated PDF does not reach the quality of the book, but I think it can be used for the production of vocational school textbooks and doujinshi.

Fixed a bug that wkhtmltopdf cannot be executed

It seems that X Server or Qt is required for PDF generation of wkhtmltopdf, but there is a bug that can not be executed if the old Qt is not patched.

QXcbConnection: Could not connect to display

One way to solve this seems to be to install wkhtmltopdf, which utilizes patched Qt. This may not be a formal means.

cd ~
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.3/wkhtmltox-0.12.3_linux-generic-amd64.tar.xz
tar vxf wkhtmltox-0.12.3_linux-generic-amd64.tar.xz

mkdir -p / usr / local / bin
sudo cp wkhtmltox / bin / wk * / usr / local / bin /

$/ usr / local / bin / wkhtmltopdf --version
