[Python] Does this PNG ByteArray make any sense?/ Sending an Image over UDP - Python,...

QByteArray s1;
QImage Image;
... // <- inbetween code that selects an image to convert for Image
QBuffer buffer(&s1);
buffer.open(QIODevice::WriteOnly);
Image.save(&buffer, "PNG");


I converted an image file into a bytearray via QTCreator's QBuffer, but I'm unsure if it's actually valid or not. I have been unable to find a place that lets me easily check if it is valid or not.

My original goal is to send an image from QTCreator to my python server via a datagram and turning it back into an image to be displayed. io.BytesIO doesn't seem to be recognizing the datagram as such, but even then what it's receiving is mildly different from the QTCreator console output. To me it seems to be skipping any event of x00 for some reason.

io.BytesIO itself it throwing this error, thus prompting me to wonder what is going wrong.

PIL.UnidentifiedImageError: cannot identify image file <_io.BytesIO object at 0x000001B63C862570>


I'm stumped and unsure how to proceed.

edit: Here is my receiving code.

from socket import *

import PIL.Image as Image

serverPort = 80

serverSocket = socket(AF_INET, SOCK_DGRAM)
serverSocket.bind(('', serverPort))
print('Send Now')
while True:
message, clientAddress = serverSocket.recvfrom(1024)

if message == b"ENDTHIS":
print(fmsg)
img = Image.open(io.BytesIO(fmsg))
img.show()
else:
fmsg += bytearray(message)
print(message)
