It looks like you're trying to use the get_data() member of a PIL
image (but it doesn't exist). get_data() is a member of cairo images,
but to access PIL images raw data you might need something like:
data = pil_image.tostring("raw","RGBA",0,1)
or (if the format is already correct), just:
data = pil_image.getdata() # (no underscore between "get" and "data").
