The crux of the discussion was the potential performance problems with base64 encode images, which would be avoided by serving the images via the WebDev module (direct byte stream). The last segment will discuss practical uses of Base64 decodings, such as Base64 image encoding and decoding. With the help of base64.b64encode () method, we can encode the string into the binary form. Once the upload is complete, the tool will convert the image to Base64 encoded binary data. Therefore, if you are not sure that your Base64 string is an image, use the Base64 to file converter since it is capable of displaying various file types. Base 64 encoding represents a common scheme for encoding binary into ASCII string format using radix 64. The goal is to convert the 8 bit stream into 6 bit characters. - mjspier Dec 3, 2019 at 11:51 So should I first save the image like cv2.imread ('img.jpg',img) then read it again? You can not base64 encode the image without reading it to memory. ASCII, UTF-8), image, email attachment, etc. Base64 encode image generates HTML code for IMG with Base64 as src (data source). This article contains examples that demonstrate how to perform Base64 encoding in Python. In its simplest form, this function takes three arguments (mode, size, and unpacked pixel data). Once converted, we can use the base64 module to encode it. In Python 2 1: s = 'SXQncyBsdW5jaCB0aW1l' print base64.b64decode (s) and in Python 3 2: s = 'SXQncyBsdW5jaCB0aW1l'.encode () print (base64.b64decode (s)) Im currently building an iOS app that requires some image processing functionality the user would scan a food label, and I would need to parse the nutritional information and return some content back to the user. - Tom Holland Dec 3, 2019 at 11:52 You don't need to encode image bytes before calling an Amazon Rekognition . Syntax : base64.b64encode (string) Return : Return the encoded string. To convert Base64 to PDF file in Python you need the base64.b64decode function and any function to write binary data into local files. Save in BytesIO""", """Send to client as image which browser will display""", # it needs object which has method `read(), """Send to client as file which browser will try to download""", # send to client as download file (with mimetype='application/octet-stream'), # mimetype='application/octet-stream') # without name as second argument because it was mimetype, # it has methodn .read() so it doesn't need to, '
