ZeroMQ pyzmq send jpeg image over tcp

image, jpeg, pyzmq, zeromq

Solution

Before sending the file you can "base64" encode it and decode it when received.

Sending:

import base64
f = open("test1.jpg",'rb')
bytes = bytearray(f.read())
strng = base64.b64encode(bytes)
socket.send(strng)
f.close()

Receiving:

import base64
message = socket.recv()
f = open("test2.jpg", 'wb')
ba = bytearray(base64.b64decode(message))
f.write(ba)
f.close()

Problem

I am trying to send a jpeg image file through a ZeroMQ connection with pyzmq, but the output is 3 times the size of the input, and no longer a valid jpeg. I load the image and send with... ``` f = open("test1.jpg",'rb') strng = f.read() socket.send(strng) f.close() ``` I receive and save with... ``` message = socket.recv() f = open("test2.jpg", 'w') f.write(str(message)) f.close() ``` I am new to zmq, and I could not find any info on sending images. Has anyone sent images through ZeroMQ, or have any ideas on how to find the problem?
