Python Pillow:Load Image with data

I need to know how to load image with its data
I use base64 module to read the data

print(base64.b64encode(open('FILENAME','rb').read()))

which gives me the image's data
I need something like

img=Load(imgdata)  #instead of Image.open()
Solution

  • Here's how to base64 encode a JPEG/PNG, or any other representation of an image:

    import base64

# Base64 encode a PNG/JPEG image
b64 = base64.b64encode(open('image.png','rb').read())

    And here's how to decode and get your image back:

    import io
from PIL import Image

# Base64 decode and convert from PNG/JPEG to PIL Image
im = Image.open(io.BytesIO(base64.b64decode(b64)))

    As an alternative, if you were using OpenCV, you might want to get back a Numpy array that OpenCV uses for image processing, in which case you could do:

    import cv2

NumpyIM = cv2.imdecode(np.asarray(bytearray(base64.b64decode(b64))),0)

    Note that this would have the blue and green channels interchanged vis-à-vis PIL/Pillow, i.e. BGR vs RGB.
