I want to return image after processing it. So far, I am able to get image to the server and process. How do I return the image so that it can be used by any client?
class ImageProcessing(Resource):
def __init__(self):
parser = reqparse.RequestParser()
parser.add_argument("image", type=werkzeug.datastructures.FileStorage, required=True, location='files')
self.req_parser = parser
def post(self):
image_file = self.req_parser.parse_args(strict=True).get("image", None)
if image_file:
image = image_file.read()
nparr = np.fromstring(image, np.uint8)
img = cv2.imdecode(nparr, cv2.IMREAD_COLOR)
img = process_img(img)
shape=img.shape
return "Image recieved: Image size {}X{}X{}".format(shape[0],shape[1],shape[2])
else:
return "Image sending failed"
Curl url:
curl -X POST -F 'image=@data/test.jpg' http://127.0.0.1:5000/processImage
How to return the processed image?
Never mind, I resolved the issue by first converting the image to base64 and then returning it as string.
rawBytes = io.BytesIO()
img.save(rawBytes, "JPEG")
rawBytes.seek(0)
img_base64 = base64.b64encode(rawBytes.read())
response = {
"shape": shape,
"image": img_base64.decode(),
"message":"Image is BASE 64 encoded"
}
return response,200
