When I try the following:
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen.canvas import Canvas
import urllib
import StringIO
import PIL.Image
image_file = urllib.urlopen('https://www.google.com/images/srpr/logo11w.png')
image_string = StringIO.StringIO(image_file.read())
logo = PIL.Image.open(image_string)
canvas = Canvas('output.pdf', pagesize=letter)
canvas.drawImage(logo, 10, 10)
canvas.showPage()
canvas.save()
I get this error:
Traceback (most recent call last):
File "imagefromurl.py", line 12, in <module>

Reportlab is version 2.5.
I was doing it the hard way. This works (also added the necessary mask to avoid transparent becoming black):
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen.canvas import Canvas
from reportlab.lib.utils import ImageReader
logo = ImageReader('https://www.google.com/images/srpr/logo11w.png')
canvas = Canvas('output.pdf', pagesize=letter)
canvas.drawImage(logo, 10, 10, mask='auto')
canvas.showPage()
canvas.save()
Though the hard way would have allowed me to detect a failure to fetch the image url and handle it (e.g. substituting a local image), and this doesn't.
