如果是EPS格式，则Python PIL Image.save（）错误

Question

I am trying to convert jpeg files to eps ones. I am using the following code:

fp=open("test.jpg",'rb')
im=Image.open(fp)
outf=open('test2.eps','wb')
im.save(outf, 'EPS')

However, I ma getting the following error:

Traceback (most recent call last):
File "im2eps2.py", line 11, in <module> im.save(outf, 'EPS')
File "C:\Python26\Lib\site-packages\PIL\Image.py", line 1465, in save
save_handler(self, fp, filename)
File "C:\Python26\Lib\site-packages\PIL\EpsImagePlugin.py", line 353, in _save
fp = io.TextIOWrapper(NoCloseStream(fp), encoding='latin-1')
File "C:\Python26\Lib\io.py", line 1429, in __init__
self._seekable = self._telling = self.buffer.seekable()
File "C:\Python26\Lib\site-packages\PIL\EpsImagePlugin.py", line 348, in __getattr__
return getattr(self.fp, name)
AttributeError: 'file' object has no attribute 'seekable'

I shall be thankful for suggestions. Thanks

PS: I reinstall PIL from its main page ie http://www.pythonware.com/products/pil/ and it worked :) Earlier, I used windows installer provided by http://www.lfd.uci.edu/~gohlke/pythonlibs . I think the problem was with the binary that I installed earlier. Currently, I have 1.1.7 PIL and it is working fine.

Thanks

According to cgohlke this was a bug in Pillow and has been fixed in 2.4.0, which was released last month (1st April 2014).

From the bug report :

io.TextIOWrapper expects an object with io.IOBase interface, not a Python 2 file object. Using fh = io.open('test.eps', 'wb') passes this stage but io.TextIOWrapper.write() expects unicode strings; the example fails with TypeError: can't write str to text stream .
