实现PDF转DOC需要以下几个步骤:
1. 安装PyQt5和PaddleOCR,并导入相关模块:
```python
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QFileDialog
from PyQt5.QtGui import QTextCursor
from PyQt5.QtCore import Qt
import paddleocr
import docx
```
2. 创建PyQt5界面,包括一个按钮和一个文本框:
```python
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
self.setGeometry(100, 100, 500, 300)
self.setWindowTitle('PDF转DOC')
self.btn = QPushButton('选择PDF文件', self)
self.btn.move(200, 100)
self.btn.clicked.connect(self.selectFile)
self.textEdit = QTextEdit(self)
self.textEdit.move(50, 150)
self.textEdit.setReadOnly(True)
```
3. 定义选择PDF文件的函数,并调用PaddleOCR进行OCR识别:
```python
def selectFile(self):
filename, _ = QFileDialog.getOpenFileName(self, '选择PDF文件', '', 'PDF files (*.pdf)')
if filename:
self.textEdit.clear()
self.textEdit.insertPlainText('正在识别,请稍候...')
QApplication.processEvents()
ocr = paddleocr.OCR()
result = ocr.ocr(filename, cls=True)
self.textEdit.clear()
doc = docx.Document()
for line in result:
if line[1][0] != '\n':
doc.add_paragraph(line[1])
else:
doc.add_paragraph(line[1][1:])
doc.save('result.docx')
self.textEdit.insertPlainText('转换完成,已保存为result.docx')
```
4. 运行PyQt5界面:
```python
if __name__ == '__main__':
app = QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())
```
