Other changes: the module cairo.gtk has been removed (pygtk 2.7.0 onwards has cairo support built in). Overview of changes from pycairo 1.2.2 to pycairo 1.2.6 ======================================================= * Pycairo 1.2.6 requires cairo 1.2.6 (or later). * mingw32 compiler fixes (Cedric Gustin) * setup.py improvements (Cedric Gustin) * ImageSurface.get_data() new method added ImageSurface.get_data_as_rgba() method removed Overview of changes from pycairo 1.2.0 to pycairo 1.2.2 ======================================================= * Pycairo requires cairo 1.2.2 (or later). * setup.py has been updated to allow installation by executing $ python setup.py install * examples/cairo_snippets/snippets/gradient_mask.py A new example to demonstrate pattern masks. * The cairo.svg module has been removed because: 1) Cairo does not include SVG parsing, so this module does not belong in pycairo. 2) libsvg-cairo (the underlying C library) is unmaintained. Overview of changes from pycairo 1.1.6 to pycairo 1.2.0 ======================================================= General changes: Pycairo has been updated to work with cairo 1.2.0.

New cairo functions supported: cairo_get_antialias cairo_set_antialias cairo_surface_mark_dirty_rectangle cairo_surface_flush Bug Fixes - double buffering now works with the cairo.gtk module Overview of changes from pycairo 0.5.1 to pycairo 0.6.0 ======================================================= 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 New wrapper functions have been added for cairo_get_font_options, cairo_set_font_options and cairo_surface_get_font_options. Overview of changes from pycairo 0.5.0 to pycairo 0.5.1 ======================================================= New features: - new class cairo.Win32Surface (Niki Spahiev) - cairo.HAS_WIN32_SURFACE, cairo.HAS_PS_SURFACE etc are defined to give access to the values from cairo-features.h Fixes: - fix cairo_mask, cairo_mask_surface and cairo_stroke_preserve wrappers - compile properly against GTK+ 2.7 (Gustavo Carneiro) - other small fixes, including fixes for gcc 4.0 warnings Overview of changes from pycairo 0.5.1 to pycairo 0.6.0 ======================================================= 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() Overview of changes from pycairo 0.1.4 to pycairo 0.4.0 ======================================================= 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. Overview of changes from pycairo 0.1.3 to pycairo 0.1.4 ======================================================= 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. Overview of changes for pycairo 0.1.3 ===================================== 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
