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())
