我需要一个样本代码或代码来读取和写入注释与状态一起回到一个新的pdf文档？

pip install PyPDF2

import PyPDF2

# 打开原始PDF文件
with open('original.pdf', 'rb') as file:
    # 创建PDF阅读器对象
    reader = PyPDF2.PdfReader(file)
    
    # 创建PDF写入器对象
    writer = PyPDF2.PdfWriter()
    
    # 遍历每一页
    for page in reader.pages:
        # 获取页面的注释和状态
        annotations = page['/Annots']
        if annotations:
            for annotation in annotations:
                # 获取注释和状态的内容
                content = annotation.getObject()['/Contents']
                status = annotation.getObject()['/Status']
                
                # 在新的PDF文档中创建新页面
                new_page = writer.add_blank_page(width=page.mediaBox.getWidth(), height=page.mediaBox.getHeight())
                
                # 将注释和状态写入新页面
                new_page.mergePage(page)
                new_page.addAnnotation(annotation)
                
                # 在新页面中添加注释和状态的内容
                new_page.drawText(10, 10, f'注释：{content}')
                new_page.drawText(10, 30, f'状态：{status}')
        
    # 保存新的PDF文档
    with open('new.pdf', 'wb') as output_file:
        writer.write(output_file)
