Python+Qt：打造功能完备的图像浏览与处理界面，待完善关键功能！

```python import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget, QLabel, QVBoxLayout, QHBoxLayout, QPushButton, QFileDialog, QSlider, QGraphicsView, QGraphicsScene from PyQt5.QtGui import QPixmap, QImage from PyQt5.QtCore import Qt class ImageProcessor(QMainWindow): def __init__(self): super().__init__() self.current_image = None self.initUI() def initUI(self): self.setWindowTitle('Image Processor') self.setGeometry(100, 100, 800, 600) self.central_widget = QWidget() self.setCentralWidget(self.central_widget) self.layout = QHBoxLayout() self.image_layout = QVBoxLayout() self.image_label = QLabel() self.image_layout.addWidget(self.image_label) self.btn_layout = QVBoxLayout() self.btn_prev = QPushButton('Previous Image') self.btn_next = QPushButton('Next Image') self.btn_open = QPushButton('Open Image Folder') self.btn_rotate = QPushButton('Rotate Image') self.btn_crop = QPushButton('Crop Image') self.btn_zoom_in = QPushButton('Zoom In') self.btn_zoom_out = QPushButton('Zoom Out') self.btn_layout.addWidget(self.btn_prev) self.btn_layout.addWidget(self.btn_next) self.btn_layout.addWidget(self.btn_open) self.btn_layout.addWidget(self.btn_rotate) self.btn_layout.addWidget(self.btn_crop) self.btn_layout.addWidget(self.btn_zoom_in) self.btn_layout.addWidget(self.btn_zoom_out) self.result_layout = QVBoxLayout() self.result_label = QLabel() self.result_layout.addWidget(self.result_label) self.layout.addLayout(self.image_layout) self.layout.addLayout(self.btn_layout) self.layout.addLayout(self.result_layout) self.central_widget.setLayout(self.layout) self.btn_prev.clicked.connect(self.previous_image) self.btn_next.clicked.connect(self.next_image) self.btn_open.clicked.connect(self.open_image_folder) self.btn_rotate.clicked.connect(self.rotate_image) self.btn_crop.clicked.connect(self.crop_image) self.btn_zoom_in.clicked.connect(self.zoom_in) self.btn_zoom_out.clicked.connect(self.zoom_out) def load_image(self, image_path): pixmap = QPixmap(image_path) self.image_label.setPixmap(pixmap) self.current_image = pixmap def previous_image(self): pass # To be implemented def next_image(self): pass # To be implemented def open_image_folder(self): folder_path = QFileDialog.getExistingDirectory(self, 'Open Image Folder') if folder_path: pass # To be implemented def rotate_image(self): pass # To be implemented def crop_image(self): pass # To be implemented def zoom_in(self): pass # To be implemented def zoom_out(self): pass # To be implemented if __name__ == '__main__': app = QApplication(sys.argv) window = ImageProcessor() window.show() sys.exit(app.exec_()) ``` 在上面的代码中，我们创建了一个名为ImageProcessor的类，继承自QMainWindow。在initUI方法中，我们设置了窗口的、大小和布局。左侧显示原图像，右侧显示处理后的结果图像。 实现了load_image方法来加载图像文件，并在界面上显示。所有按钮的点击事件暂时为空，需要进一步实现。 需要完善的功能包括： - 实现previous_image和next_image方法，允许用户在文件夹中选择上一张和下一张图像。 - 打开图像文件夹并显示其中的图像。 - 实现图像处理功能，如旋转、裁剪、放大缩小。 - 实现缩放功能，允许用户放大或缩小图像。 ######[AI写代码神器 | 2432点数解答 | 2024-07-28 09:38:11]
