pyqt5指定路径打开图片的代码

Sure, here is the code for opening an image with a specified path using PyQt5:

from PyQt5.QtGui import QPixmap, QPainter
from PyQt5.QtWidgets import QMainWindow, QApplication, QGraphicsScene, QGraphicsView, QGraphicsPixmapItem, QVBoxLayout, QPushButton
import os

class App(QMainWindow):
    def __init__(self, path):
        super().__init__()
        self.setWindowTitle("Image Viewer")

        # Create graphics scene
        self.scene = QGraphicsScene(self)
        self.view = QGraphicsView(self.scene)
        self.view.setRenderHint(QPainter.Antialiasing)
        self.view.setRenderHint(QPainter.SmoothPixmapTransform)

        # Load image from path and add to scene
        if os.path.isfile(path):
            pixmap = QPixmap(path)
            item = QGraphicsPixmapItem(pixmap)
            self.scene.addItem(item)
            self.view.fitInView(item, 1)

        # Add view to layout
        layout = QVBoxLayout()
        layout.addWidget(self.view)

        # Add layout to main window
        container = QWidget()
        container.setLayout(layout)
        self.setCentralWidget(container)


if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)

    # Specify image path here
    image_path = "<path_to_image>"
    
    # Create and show application
    ex = App(image_path)
    ex.show()
    
    sys.exit(app.exec_())

Hope this helps!
