1.11.1 - 2017-04-12

This release fixes an ABI breakage. I missed that the original pycairo master had already broken ABI compared to 1.10.0.

1.11.0 - 2017-04-09

This version is based on the Python 2 version of pycairo 1.10.0 and is API/ABI compatible with both py2cairo 1.10.0 and py3cairo 1.10.0.

General Changes:

  • Requires cairo 1.10.2+

  • Switch to semantic versioning

  • Switch build system to distutils/setup.py (xpyb integration can be enabled with passing --enable-xpyb to setup.py build)

  • Moved to GitHub: https://github.com/pygobject/pycairo

New Features:
Bug Fixes:

  • Fix crash when read()/write() methods of file objects passed to pycairo raise exceptions.

  • Fix possible value truncation of handles passed to Win32Surface and Win32PrintingSurface on 64bit Windows. #fdo-57493

1.10.0 - 2011-05-01

General Changes:

New Classes/Types:

  • Win32PrintingSurface

  • XCBSurface - add XCB support using xpyb

Bug Fixes:
Other Changes:

Tests updated.

The Win32PrintingSurface and XCBSurface changes mean that pycairo 1.8.10 is not binary compatible with pycairo 1.8.8. So modules that use the pycairo C API (like pygtk) will need to be recompiled to use pycairo 1.8.10.

1.8.8 - 2009-08-26

General Changes:

  • Pycairo 1.8.8 requires cairo 1.8.8 (or later).

Bug Fixes:

  • #fdo-19287: Threading support results in crashes in cairo.ImageSurface

New Methods:

Context.set_scaled_font

API Changes:

Matrix multiplication:

old code: matrix3 = matrix1 * matrix2
new equivalent code: matrix3 = matrix1.multiply(matrix2)
matrix3 = matrix1 * matrix2
is now equivalent to matrix3 = matrix2.multiply(matrix1)
which is consistent with standard matrix multiplication.

0.6.0 - 2005-08-01

This version has many changes which update Pycairo to the new cairo API. The change list is not duplicated here, instead see the cairo/NEWS file for full details of all these API changes.

Pycairo method names that were different from the underlying cairo function names have been changed to make Pycairo more closely follow cairo and so enable the cairo documentation to be used for writing Pycairo programs. NOTES has been updated to list the differences between the C API and the Pycairo API.

Context.copy_path() has been implemented, it returns a Path instance which supports the iterator protocol.

Python 2.3 is now required.

New examples:

examples/warpedtext.py: shows usage of the Path iterator

examples/cairo_snippets/: shows many of the ‘cairo-demo/cairo_snippets’ examples

examples/gtk/png_view.py: example using cairo.ImageSurface.create_from_png()

General changes:

Pycairo has been updated to work with cairo 0.6.0, including using cairo’s new error handling scheme.

New features:

cairo.CONTENT_COLOR, cairo.ALPHA, cairo.COLOR_ALPHA have been added for working with surfaces.

A new class cairo.FontOptions has been added.

cairo.ImageSurface.create_from_png() now accepts a filename string or a file object

0.4.0 - 2005-03-10

New cairo bindings:
cairo_font_extents
Bindings removed:
cairo_font_set_transform
cairo_font_current_transform
New examples:

gtk/hangman.py

Other:

Changed version numbering to correspond directly with the Cairo version Pycairo was developed to work with. So, for example, Pycairo version 0.4.0 represents the Pycairo version that has been developed and tested with Cairo 0.4.0.

0.1.4 - 2005-01-14

The Pycairo license has changed so that it is now dual-licensed under the LGPL and the MPL, the same as Cairo itself. For details see the COPYING file as well as COPYING-LGPL-2.1 and COPYING-MPL-1.1.

New cairo bindings:
cairo_pdf_surface_create
cairo_set_target_pdf
New libsvg-cairo bindings:
svg_cairo_parse
svg_cairo_parse_buffer
svg_cairo_render
svg_cairo_get_size
Other:

  • Added –without-pygtk configure option.

  • Renamed the Pycairo API _new() functions to _wrap() to allow _new() to

  • be used for python __new__ functions.

  • New examples: svg2png.py and svgview.py.

0.1.3 - 2004-11-24

After the recent server compromise we discarded all unsigned snapshots. That left us without a pycairo snapshot.

Additionally, there were no tags in the source repository so I couldn’t recreate the 0.1.2 snapshot, so here’s a new 0.1.3 snapshot.

I apologize if I botched the version number or left something significant out of this announcement—I’m not the one who will usually be doing pycairo maintenance.

New bindings:
current_path
current_path_flat
current_font_extents
Changes:

fill_extents,stroke_extents: Remove unnecessary args and change from a method to an attribute.

Other:

Added two new examples: context-subclass.py and warpedtext.py
