Hi mpl users,
I am trying to save a figure to a file like object (a StringIO object)
and load this object into PIL (Python Imaging Library). The code for
this is really simple (fig is my figure object):
# This works
fig.savefig('test.png', format='png')
im = Image.open('test.png')
# This fails
imgdata = StringIO.StringIO()
fig.savefig(imgdata, format='png')
im = Image.open(imgdata)
File "/home/jl/testfile.py", line 551, in contour
im = Image.open(imgdata)
File "/usr/lib/python2.5/site-packages/PIL/Image.py", line 1916, in open
raise IOError("cannot identify image file")
IOError: cannot identify image file
Does anyone know what I am doing wrong? I would really like to avoid
putting the image on disk before opening it in PIL since I am using
the code in a web application where speed is important.
Best regards,
Jesper
