(description "WeasyPrint helps web developers to create PDF documents. It
|

turns simple HTML pages into gorgeous statistical reports, invoices, tickets,
|
||||
etc.
|
||||
|
||||
From a technical point of view, WeasyPrint is a visual rendering engine for
|
||||
HTML and CSS that can export to PDF and PNG. It aims to support web standards
|
||||
for printing.
|
||||
|
||||
It is based on various libraries but not on a full rendering engine like
|
||||
WebKit or Gecko. The CSS layout engine is written in Python, designed for
|
||||
pagination, and meant to be easy to hack on. Weasyprint can also be used as a
|
||||
python library.
