Python图像拼接

772

我有一个大图像，它被平铺成相同大小的瓷砖。名称格式为 - < Номер строки> _< Номер столбца>。

我想将它们全部粘贴到一个大图像中，但我不知道该怎么做。最初，我想先将线条分别粘合，然后将它们组合成一个大图像，但我不知道如何实现。

UPD：我忘了补充另一个问题是有相当多的片段（1104），每个片段重约2.1MB。

在运行我的示例之前，请确保您已经安装了PyQt5

pip install PyQt5
pip install pyqt5-tools

PyQt是Python 语言的Qt框架的实现。

import sys 
from PyQt5.Qt import * 
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
        self.centralWidget = QWidget()
        self.setCentralWidget(self.centralWidget)
        
        list_image = [
            ['image11.png', 'image21.png', 'image31.png'],
            ['image12.png', 'image22.png', 'image32.png'],
            ['image13.png', 'image23.png', 'image33.png'],
        ]
  
        button = QPushButton("Click my", self)
        button.setCheckable(True)
        button.clicked.connect(self.button_clicked)
        
        self.layout = QGridLayout(self.centralWidget)
        
        for row in range(len(list_image)):
            for column in range(len(list_image[0])):
                label = QLabel()
                label.setPixmap(QPixmap(list_image[row][column]))
                self.layout.addWidget(label, row+1, column+1)
                
        self.layout.setRowStretch(0, 1) 
        self.layout.setRowStretch(4, 1)        
        self.layout.setColumnStretch(0, 1) 
        self.layout.setColumnStretch(4, 1) 
        self.layout.addWidget(button, 6, 2)
        
    def button_clicked(self, state):
        if state:
            self.layout.setSpacing(0)
        else:
            self.layout.setSpacing(10)
        
  
if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = Window()
    window.show()
    sys.exit(app.exec_())

Vadim，您需要帮助从片段制作多维列表吗？

不，只是这些片段的整个文件

import sys 
from PyQt5.Qt import * 
  
  
class Window(QMainWindow):
    def __init__(self):
        super().__init__()
  
        self.centralWidget = QWidget()
        self.setCentralWidget(self.centralWidget)
        
        list_image = [
            ['image11.png', 'image21.png', 'image31.png'],
            ['image12.png', 'image22.png', 'image32.png'],
            ['image13.png', 'image23.png', 'image33.png'],
        ]
  
        button = QPushButton("Click my", self)
        button.setCheckable(True)
        button.clicked.connect(self.button_clicked)
        
        self.widget = QWidget(self.centralWidget)

        pixmap.save(fname) 

        self.label_image = QLabel()
        self.label_image.setWindowTitle(f'{fname} !!!')
        self.label_image.setPixmap(QPixmap(fname))
