QPixmap和QBitmap绘图的效果对比

import sys
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtGui import QPixmap, QPainter, QBitmapclass MyForm(QWidget):def __init__(self, parent=None):super(MyForm, self).__init__(parent)self.setWindowTitle("不规则窗口的实现例子")def paintEvent(self, event):painter = QPainter(self)painter.drawPixmap(0, 0, 280, 390, QPixmap(r"./pyqt5/images/dog.jpg"))painter.drawPixmap(300, 0, 280, 390, QBitmap(r"./pyqt5/images/dog.jpg"))if __name__ == "__main__":app = QApplication(sys.argv)form = MyForm()form.show()sys.exit(app.exec_())

不可以拖动的不规则窗口
