WeasyPrint 0.16: PDF zoom and bug fixes
A small release this time.
zoom parameter on PDF output can change
the ratio between CSS length units and PDF units.
The various CSS units however still have the same relative ratios:
a CSS pixel is always one 96th of an inch.
This can be a work-around for using an existing fixed-width CSS layout
on various page sizes.
A few bugs in WeasyPrint were fixed and some in pycairo were worked around.
This restores compatibility with Debian Squeeze and other distributions that
still use broken versions of pycairo.
Changelog for 0.16.
WeasyPrint 0.15: More API, more docs, more fixes
0.15 is (finally!) out. This one is light in CSS features, but
Sphinx-based documentation as well as a new API with low-level access
to individual pages.
Backward-incompatible change: the
HTML.get_png_pages() method is gone,
it was ridiculously specific compared to the new API. It can be reproduced
"""Yield (png_bytes, width, height) tuples."""
for page in document.pages:
Changelog for 0.15.
WeasyPrint 0.13: PyGTK compatibility
0.13 will fall back on PyGTK if PyGObject 3 is not available.
This enables WeasyPrint to run and pass its tests on Debian Squeeze
(the current stable, as of this writing.)
Hopefully this will make WeasyPrint easier to install on more platforms
such as OS X. Testers wanted!
WeasyPrint 0.12: border-collapse and Flask-WeasyPrint
WeasyPrint 0.12 is out.
This release adds support for the collapsing border model of tables, through
border-collapse property. Previously, table borders were always
separated. This new model is incompatible with table headers and footers:
are treated like normal
<tbody> groups and are not repeated on each page.
On an unrelated note, 0.12 also adds the URL fetcher
hook to the public API. It allows to control or override how WeasyPrint
accesses HTTP or other URLs for HTML documents, CSS stylesheets, and images.
a new extension that makes use of an URL fetcher to integrate WeasyPrint
in a Flask application.
WeasyPrint 0.11: floats, Acid2 and unprefixing
WeasyPrint 0.11 is out.
It has not been long since 0.10, but the point of this release is to
finally merge the support for floats and clear that we have had for a
while in an experimental branch.
With this (and countless other bug fixes), WeasyPrint now passes the
Acid2 test! See the details or try it yourself:
weasyprint http://www.webstandards.org/files/acid2/test.html acid2.pdf

And now for something completely different, the
size properties are unprefixed. The prefixed form
-weasy-size) is ignored but gives a specific warning.
You will need to change your stylesheets if you used any of these with a

WeasyPrint 0.8, tinycss and cssselect
Some new features as
usual. The big one is automatic layout for tables. Roughly, columns will get
their width determined by the amount of content.
Other important but more underlying changes are
cssselect. tinycss is a new CSS parser
I wrote from scratch as a smaller and faster alternative to
cssutils. You can
read more about it on my blog. As
to cssselect, I took over its maintenance after extracting it from
lxml. It now supports most Level 3 selectors and can be
extended more easily.
WeasyPrint 0.4 to 0.7; BSD license
I’ve been neglecting this “news” section for a while, and a lot has happened
Versions 0.4 to 0.7 of WeasyPrint have brought many
new features. The
big ones are Python 3 support, page headers and footers with page counters,
justified text, 2D transforms, and better page break control. The list of
missing CSS 2.1 features is shrinking
Features aside, and perhaps more importantly, the project is now BSD-licensed
starting from 0.7.1. (I did not bother to re-release the previous version
with the new license, but just ask if you need them.)
This less restrictive license will hopefully bring more users.
By the way, the project’s mailing-list is now up and running.
WeasyPrint 0.3: SVG images and generated content
New WeasyPrint release. The big features in 0.3 are SVG images and generated
content with the

Tables in WeasyPrint!
I just released WeasyPrint 0.2, now with tables!
This new version also has other minor new features and bug fixes. See the
WeasyPrint 0.1 is released
WeasyPrint finally got its first release!
It’s a rendering engine for HTML and CSS that produces PDF.
This 0.1 release has support for basic CSS2.1 without tables, floats or
absolute positioning. However it can already be useful for documents with
a “simple” layout.
Grab it, use it, hack it:
