I can't fit image in Qlabel

hernancrespo89

Hi i am new with PyQt and i am using QtDesigner and Python.
i have been trying to display a image on Qt. I acquire image from webcam and it's size is 640x480. But i don't want display it on full size. I want to display it on a label. Size of label is not important. When i display it on a label. It crops the image and it shows some pixels (as expected). But i want to fit image in Qlabel. So i tried to set QSizePolicy=Ignored and QSizePolicy=Fixed using QtDesigner but bot of them didn't work. How can i display image like i said?

my codes:

main.py

from PyQt5.QtWidgets import *

from qt_ilk import loadUi_example


if __name__ == '__main__': 

    app = QApplication([])
    start_window = loadUi_example()
    start_window.show()
    app.exit(app.exec_())

and qt_ilk.py

from PyQt5.QtWidgets import *
from PyQt5.uic import loadUi
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtGui import QPixmap, QImage
import cv2

class loadUi_example(QMainWindow):

    def __init__(self):
        super().__init__()
        loadUi("qt_ilk.ui", self)

    @pyqtSlot()
    def on_buon2_clicked(self):
        cap = cv2.VideoCapture(0)

        ret, frame = cap.read()
        frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
        if frame is not None:
            image = QImage(frame, frame.shape[1], frame.shape[0],
                           QImage.Format_RGB888)  # The image is stored using a 24-bit RGB format (8-8-8).

            self.pixmap = QPixmap.fromImage(image)
        self.label.setPixmap(self.pixmap)
        cap.release()

        cv2.destroyAllWindows()

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(1000, 1000)
        self.buon2 = QtWidgets.QPushButton(Form)
        self.buon2.setGeometry(QtCore.QRect(150, 200, 75, 23))
        self.buon2.setObjectName("buon2")
        self.label = QtWidgets.QLabel(Form)
        self.label.setGeometry(QtCore.QRect(170, 70, 47, 13))
        self.label.setText("")
        self.label.setObjectName("label")
        self.buton1 = QtWidgets.QPushButton(Form)
        self.buton1.setGeometry(QtCore.QRect(150, 160, 75, 23))
        self.buton1.setObjectName("buton1")

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.buon2.setText(_translate("Form", "goster"))
        self.buton1.setText(_translate("Form", "temizle"))

Is QLabel.setScaledContents(true) what you are looking for?
