Dear all, I am pleased to announce the release of mplcairo 0.1 # Description mplcairo is a Matplotlib backend based on the well-known cairo library, supporting output to both raster (including interactively) and vector formats. In other words, it provides the functionality of Matplotlib's {,qt5,gtk3,wx,tk,macos}{agg,cairo}, pdf, ps, and svg backends. Per Matplotlib's standard API, the backend can be selected by calling matplotlib.use("module://mplcairo.qt") or setting your MPLBACKEND environment variable to `module://mplcairo.qt` for Qt5, and similarly for other toolkits. The source tarball, and Py3.6 manylinux and Windows wheels, are available on PyPI (I am looking for help to generate the OSX wheels). See the README for more details. # Why a new backend? Compared to Matplotlib's builtin Agg and cairo backends, mplcairo presents the following features: - Improved accuracy (e.g., with marker positioning, quad meshes, and text kerning). - Support for a wider variety of font formats, such as otf and pfb, for vector (PDF, PS, SVG) backends (Matplotlib's Agg backend also supports such fonts). - Optional support for complex text layout (right-to-left languages, etc.) using Raqm. **Note** that Raqm depends on Fribidi, which is licensed under the LGPLv2.1+. - Support for embedding URLs in PDF (but not SVG) output (requires cairo≥1.15.4). - Support for multi-page output both for PDF and PS (Matplotlib only supports multi-page PDF). - Support for custom blend modes (see `examples/operators.py`). See the README for more details. # Changelog from mplcairo 0.1a1 to mplcairo 0.1 - Integration with libraqm now occurs via dlopen() rather than being selected at compile-time. - Various rendering and performance improvements. - On Travis, we now run Matplotlib's test suite with mplcairo patching the default Agg renderer. Enjoy, Antony Lee
Congratulations to Antony for his hard work on this important backend! As far as I am concerned, the cairo backend is the future of matplotlib. Test this backend out for yourselves and help us take matplotlib to the next level in high-quality charting! Cheers!

# Description
mplcairo is a Matplotlib backend based on the well-known cairo library, supporting output to both raster (including interactively) and vector formats. In other words, it provides the functionality of Matplotlib's {,qt5,gtk3,wx,tk,macos}{agg,cairo}, pdf, ps, and svg backends.
Per Matplotlib's standard API, the backend can be selected by calling
matplotlib.use("module://mplcairo.qt")
or setting your MPLBACKEND environment variable to `module://mplcairo.qt` for Qt5, and similarly for other toolkits.
The source tarball, and Py3.6 manylinux and Windows wheels, are available on PyPI (I am looking for help to generate the OSX wheels).
See the README for more details.
# Why a new backend?
Compared to Matplotlib's builtin Agg and cairo backends, mplcairo presents the following features:
- Improved accuracy (e.g., with marker positioning, quad meshes, and text kerning). - Support for a wider variety of font formats, such as otf and pfb, for vector (PDF, PS, SVG) backends (Matplotlib's Agg backend also supports such fonts). - Optional support for complex text layout (right-to-left languages, etc.) using Raqm. **Note** that Raqm depends on Fribidi, which is licensed under the LGPLv2.1+. - Support for embedding URLs in PDF (but not SVG) output (requires cairo≥1.15.4). - Support for multi-page output both for PDF and PS (Matplotlib only supports multi-page PDF). - Support for custom blend modes (see `examples/operators.py`).

# Changelog from mplcairo 0.1a1 to mplcairo 0.1
- Integration with libraqm now occurs via dlopen() rather than being selected at compile-time. - Various rendering and performance improvements. - On Travis, we now run Matplotlib's test suite with mplcairo patching the default Agg renderer.
