python convert image to base64

import base64

file = 'deer.jpg'
image = open(file, 'rb')
image_read = image.read()
image_64_encode = base64.encodebytes(image_read) #encodestring also works aswell as decodestring

print('This is the image in base64: ' + str(image_64_encode))

image_64_decode = base64.decodebytes(image_64_encode) 
image_result = open('deer_decode.jpg', 'wb') # create a writable image and write the decoding result
image_result.write(image_64_decode)

php image to base64

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

test image as base 64 string

buffer from base64

const b64string = /* whatever */;
const buf = Buffer.from(b64string, 'base64');

converting image to base64 string

router.post('/upload',function(req,res){
var base64ToBuffer = new Buffer(req.image, 'base64');//Convert to base64

//Write your insertcode of MongoDb

res.end("Image uploaded Successfully"); 
});

Qt convert image to base64

# Python Solution
# The PIL Module has a class that helps with this.
from PIL.ImageQt import ImageQt

image = PySide2.QtGui.QPixmap.toImage()
image = ImageQt(image)
# Now you have an object with PIL + Qt support.
import base64
from io import BytesIO

buffered = BytesIO()
image.save(buffered, format="JPEG")
img_str = base64.b64encode(buffered.getvalue())
