I just updated backend_cairo.py to work with the latest version of pycairo. The cairo backend can now output PNG, PDF, PS and SVG to a filename or a file-like object.
However, print_figure() does not support writing to file objects in different formats because it only takes a 'filename' argument and does not have an argument to allow you to specify the format. If the filename is string-like it writes to the filename (and the format is often encoded into the string, as in 'file.png' for example) If the filename is not string-like the backend has no way to know which format is required and has to choose a default format (agg defaults to PNG). I think print_figure() should be changed from print_figure (filename, ...) to print_figure (filename, format='png', ...) where format is in ('png', 'ps', 'svg') etc And savefig() would need a corresponding change. This would allow backends to write to file-like objects in the requested format. For example, you could then write to a file-like object in SVG format. Any comments?
