X Title: Matplotlib savefig() closes BytesIO object when saving in postscript format by mdboom · Pull Request #1862 · matplotlib/matplotlib

Description: In Python 3, I am seeing the following bug: In [1]: from io import BytesIO In [2]: import matplotlib.pyplot as plt In [3]: b = BytesIO() In [4]: fig = plt.figure() In [5]: ax = fig.add_subplot(1,1,1) In [6]: ax.plot([1,2,3]) Out[6]: [] In [7]: fig.savefig(b, format='eps') In [8]: b.seek(0) --------------------------------------------------------------------------- ValueError Traceback (most recent call last) in () ----> 1 b.seek(0) ValueError: I/O operation on closed file. As far as I can tell, this does not occur with StringIO in Python 2.x. @mdboom - is this related to #1779?
