파이썬 Qpainter 크기 조정

Question

나는 내 Qpainter의 크기를 변경하려고했는데 내가 어떻게 도와 줄 수 있는지 알아낼 수 없다. 내 코드는 내가 온라인으로 보았고 내가 필요로하는 코드가 포함되어 있기 때문에 알아낼 수 없다. 당신의 도움을 필요로하지 않는 다른 코드의 똥 소리.

import sys 
import os 
from PyQt4.QtCore import QSize, QTimer 
from PyQt4.QtGui import QApplication,QGraphicsRectItem , QMainWindow, QPushButton, QWidget, QIcon, QLabel, QPainter, QPixmap, QMessageBox, QAction, QKeySequence, QFont, QFontMetrics, QMovie 
from PyQt4 import QtGui 


class UIWindow(QWidget): 
    def __init__(self, parent=None): 
     super(UIWindow, self).__init__(parent) 
     self.resize(QSize(400, 450)) 

    def paintEvent(self, event): 
     painter = QPainter(self) 
     painter.drawPixmap(self.rect(), QPixmap("Images\Image.png")) 
     painter.move(0,0) 
     painter.resize(950,270) 




class MainWindow(QMainWindow,): 
    def __init__(self, parent=None): 
     super(MainWindow, self).__init__(parent) 
     self.setGeometry(490, 200, 950, 620) 
     self.setFixedSize(950, 620) 
     self.startUIWindow() 
     self.setWindowIcon(QtGui.QIcon('Images\Logo.png')) 

    def startUIWindow(self): 
     self.Window = UIWindow(self) 
     self.setWindowTitle("pythonw") 
     self.setCentralWidget(self.Window) 
     self.show() 

if __name__ == '__main__': 
    app = QApplication(sys.argv) 
    w = MainWindow() 
    sys.exit(app.exec_())

drawPixmap 기능은 첫번째 파라미터로 그려 될 사각형, 즉 (0, 0, 폭, 높이)

def paintEvent(self, event): 
    painter = QPainter(self) 
    pixmap = QPixmap("Images\Image.png") 
    painter.drawPixmap(QRect(0, 0, pixmap.width(), pixmap.height()), pixmap)
