Comment(by jason):
Yes, I'm almost sure that #5448 will necessitate an update (or this will
necessitate an update of #5448).
1. I would change the keyword argument to something that is used more in
Sage (like alpha or opacity) if we are going to have multiple levels of
transparency. If it is just a True/False option, then "transparent" seems
like a fine keyword.
2. What do you think about using the "transparent" option of savefig, as
documented here:
http://matplotlib.sourceforge.net/api/figure_api.html#matplotlib.figure.Figure.savefig
?
3. The transparent option of savefig has the following code. It looks
like this code not only sets the figure patch, but goes through each axes
object in the figure and sets the axes patch alpha level. We should
probably do the same.
{{{
1036 if transparent:
1037 original_figure_alpha = self.patch.get_alpha()
1038 self.patch.set_alpha(0.0)
1039 original_axes_alpha = []
1040 for ax in self.axes:
1041 patch = ax.patch
1042 original_axes_alpha.append(patch.get_alpha())
1043 patch.set_alpha(0.0)
}}}
