Writing opencv image to zip file in python

Question

I have an opencv image:

img = cv2.imread(filename)
img = cv2.GaussianBlur(img, (5, 5), 0.15)

now I want to write it directly into zip

zipf = zipfile.ZipFile('out.zip', 'w', zipfile.ZIP_DEFLATED)
zipf.write(...)

Guess it's something to do with cv2.imencode() but not sure.
Can you help? Thanks

Found the answer:

zipf = zipfile.ZipFile('out.zip', 'w', zipfile.ZIP_DEFLATED)
retval, buf = cv2.imencode('.png', img)
zipf.writestr(name_in_zip, buf)

works like a charm.
