[reportlab-users] PIL frombuffer question

Hello. I'm trying to write raw pixel data to a pdf using reportlab.
I've attempted to do this by creating a PIL image using frombuffer, create an ImageReader object from that PIL image, then draw this on the canvas. Here's my test code:

data = ''.join([chr(x%255) for x in range(30000)])
im = PIL.Image.frombuffer ('RGB', (100,100), data, "raw", 'RGB', 0, 1)
ir = ImageReader (im)

c = Canvas("test.pdf", pagesize=letter)
c.drawImage (ir, 100, 100, 100, 100)
c.showPage ()
c.save ()

However, I get the following error:
Traceback (most recent call last):
File "imagetest.py", line 3, in ?
ir = ImageReader (im)
File "reportlab\lib\utils.py", line 518, in __init__
File "C:\Python24\Lib\site-packages\PIL\Image.py", line 493, in __getattr__
raise AttributeError(name)
AttributeError: fp

So there seems to be problem with there not being a file? Any thoughts on what I'm doing wrong? Or a better way to accomplish this?
