Check whether a figure is empty
43+
-------------------------------
44+
Empty can actually mean different things. Does the figure contain any artists?
45+
Does a figure with an empty `~.axes.Axes` still count as empty? Is the figure
46+
empty if it was rendered pure white (there may be artists present, but they
47+
could be outside the drawing area or transparent)?
48+
49+
For the purpose here, we define empty as: "The figure does not contain any
50+
artists except it's background patch." The exception for the background is
51+
necessary, because by default every figure contains a `.Rectangle` as it's
52+
background patch. This definition could be checked via::
53+
54+
def is_empty(figure):
55+
"""
56+
Return whether the figure contains no Artists (other than the default
57+
background patch).
58+
"""
59+
contained_artists = figure.get_children()
60+
return len(contained_artists) <= 1
61+
62+
We've decided not to include this as a figure method because this is only one
63+
way of defining empty, and checking the above is only rarely necessary.
64+
Usually the user or program handling the figure know if they have added
65+
something to the figure.
66+
67+
Checking whether a figure would render empty cannot be reliably checked except
68+
by actually rendering the figure and investigating the rendered result.
