[reportlab-users] pdfgen gives me AttributeError: jpeg_fh

[Gregory Piñero]

(sorry if this gets sent twice, my email is acting funny)

Hi guys,

Here's the error I'm getting, any idea what's going on?

Traceback (most recent call last):
  File "<string>", line 59, in <module>
  File "<string>", line 46, in put_in_front_picture
  File "/usr/lib/python2.5/site-packages/reportlab/pdfgen/canvas.py",
line 629, in drawImage
    imgObj = pdfdoc.PDFImageXObject(name, image, mask=mask)
  File "/usr/lib/python2.5/site-packages/reportlab/pdfbase/pdfdoc.py",
line 1842, in __init__
    self.loadImageFromSRC(source)
  File "/usr/lib/python2.5/site-packages/reportlab/pdfbase/pdfdoc.py",
line 1891, in loadImageFromSRC
    fp = im.jpeg_fh()
  File "/usr/lib/python2.5/site-packages/PIL/Image.py", line 493, in __getattr__
    raise AttributeError(name)
AttributeError: jpeg_fh

I've pasted my code below if it helps. Thanks.
