graphics¶This module implements an API similar to wx.GraphicsContext and the related classes. In this case the implementation for all platforms is done using Cairo, via the wx.lib.wxcairo glue module.
Why do this? Why not just use wx.GraphicsContext everywhere? Using Cairo on every platform enables us to more easily be totally consistent on all platforms. Implementing it in Python means that it is easy to fill in the gaps in functionality with features of Cairo that GraphicsContext may not provide, like converting text to a path, using compositing operators, or being able to provide an implementation for things like context.Clear().
Why not just use Cairo directly? There may be times when you do want to use wx.GrpahicsContext, so being able to share code between that and this implementation is nice. Also, I like the class hierarchy and API exposed by the wx.GraphicsContext classes a little better than Cairo’s.
