QLabel with image in round shape

Question

I want to display image with round shape in PyQt5/PySide2 application.

Below is the code i tried.

self.statusWidget = QLabel()
img = QImage(":/image.jpg").scaled(49, 49, Qt.IgnoreAspectRatio, Qt.SmoothTransformation)
self.statusWidget.setPixmap(QPixmap.fromImage(img))
self.statusWidget.setStyleSheet("border-radius:20px")

I got below output.

And I want Qlabel like below.

This method uses the setClipPath QPainter method in conjunction with QPainterPath to crop the image.

import sys
from PyQt5.QtCore    import Qt
from PyQt5.QtGui     import QPixmap, QPainter, QPainterPath
from PyQt5.QtWidgets import QLabel, QWidget, QHBoxLayout, QApplication

class Label(QLabel):
    def __init__(self, *args, antialiasing=True, **kwargs):
        super(Label, self).__init__(*args, **kwargs)
        self.Antialiasing = antialiasing
        self.setMaximumSize(50, 50)
        self.setMinimumSize(50, 50)
        self.radius = 25 

        self.target = QPixmap(self.size())  
        self.target.fill(Qt.transparent)   

        p = QPixmap("E:/_Qt/img/qt-logo.png").scaled(  
            50, 50, Qt.KeepAspectRatioByExpanding, Qt.SmoothTransformation)

        painter = QPainter(self.target)
        if self.Antialiasing:
            painter.setRenderHint(QPainter.Antialiasing, True)
            painter.setRenderHint(QPainter.HighQualityAntialiasing, True)
            painter.setRenderHint(QPainter.SmoothPixmapTransform, True)

        path = QPainterPath()
        path.addRoundedRect(
            0, 0, self.width(), self.height(), self.radius, self.radius)

        painter.setClipPath(path)
        painter.drawPixmap(0, 0, p)
        self.setPixmap(self.target)

class Window(QWidget):
    def __init__(self, *args, **kwargs):
        super(Window, self).__init__(*args, **kwargs)
        layout = QHBoxLayout(self)
        layout.addWidget(Label(self))
        layout.addWidget(Label(self, antialiasing=False))  
        self.setStyleSheet("background: blue;")           

if __name__ == "__main__":
    app = QApplication(sys.argv)
    w = Window()
    w.show()
    sys.exit(app.exec_())
