How do I create an OpenCV image from the contents of a file?
Question
Usually I would create an image in OpenCV as:
from cv2 import imread
img = imread("/home/nick/myfile.jpg")
But already have the contents of the file in another variable, so how to I create an OpenCV from this directly? eg
fc = open("/home/nick/myfile.jpg", "rb").read()
img = something(fc)
What is something ? Is there an OpenCV or numpy function to do this?

cv2.imdecode() can do that in memory. and yes, it wants a numpy array as input
