利用Python实现Word文档与PDF文档的格式转化（提取PDF文本内容），实现PDF文件的合并、拆分，PDF页面旋转已经PDF页面增加水印。的具体代码

答：好的，以下是Python实现Word和PDF文档转换、合并、拆分、页面旋转和添加水印的代码示例：

1. 将Word文档转换为PDF文档：

import win32com.client
 
def word_to_pdf(word_file, pdf_file):
    word = win32com.client.Dispatch('Word.Application')
    doc = word.Documents.Open(word_file)
    doc.SaveAs(pdf_file, FileFormat=17)
    doc.Close()
    word.Quit()
 
if __name__ == '__main__':
    word_file = r'C:\path\to\your\word\file.docx'
    pdf_file = r'C:\path\to\your\pdf\file.pdf'
    word_to_pdf(word_file, pdf_file)

2. 提取PDF文本内容：

import PyPDF2
 
def extract_text(pdf_file):
    pdf_reader = PyPDF2.PdfFileReader(pdf_file)
    text = ''
    for i in range(pdf_reader.getNumPages()):
        page = pdf_reader.getPage(i)
        text += page.extractText()
    return text
 
if __name__ == '__main__':
    pdf_file = r'C:\path\to\your\pdf\file.pdf'
    text = extract_text(pdf_file)
    print(text)

3. 合并PDF文件：

import PyPDF2
 
def merge_pdfs(input_files, output_file):
    merger = PyPDF2.PdfFileMerger()
    for input_file in input_files:
        merger.append(input_file)
    merger.write(output_file)
    merger.close()
 
if __name__ == '__main__':
    input_files = [r'C:\path\to\your\pdf\file1.pdf', r'C:\path\to\your\pdf\file2.pdf']
    output_file = r'C:\path\to\your\output\merged.pdf'
    merge_pdfs(input_files, output_file)

4. 拆分PDF文件：

import os
import PyPDF2
 
def split_pdf(input_file, output_dir):
    pdf_reader = PyPDF2.PdfFileReader(input_file)
    for i in range(pdf_reader.getNumPages()):
        pdf_writer = PyPDF2.PdfFileWriter()
        pdf_writer.addPage(pdf_reader.getPage(i))
        output_file = os.path.join(output_dir, f'page_{i+1}.pdf')
        with open(output_file, 'wb') as fh:
            pdf_writer.write(fh)
 
if __name__ == '__main__':
    input_file = r'C:\path\to\your\pdf\file.pdf'
    output_dir = r'C:\path\to\your\output\dir'
    split_pdf(input_file, output_dir)

5. 旋转PDF页面：

import PyPDF2
 
def rotate_pdf(input_file, output_file, degrees):
    pdf_reader = PyPDF2.PdfFileReader(input_file)
    pdf_writer = PyPDF2.PdfFileWriter()
    for i in range(pdf_reader.getNumPages()):
        page = pdf_reader.getPage(i)
        page.rotateClockwise(degrees)
        pdf_writer.addPage(page)
    with open(output_file, 'wb') as fh:
        pdf_writer.write(fh)
 
if __name__ == '__main__':
    input_file = r'C:\path\to\your\pdf\file.pdf'
    output_file = r'C:\path\to\your\output\rotated.pdf'
    degrees = 90
    rotate_pdf(input_file, output_file, degrees)

6. 添加PDF页面水印：

import PyPDF2
 
def add_watermark(input_file, output_file, watermark_path):
    pdf_reader = PyPDF2.PdfFileReader(input_file)
    watermark_reader = PyPDF2.PdfFileReader(open(watermark_path, 'rb'))
    pdf_writer = PyPDF2.PdfFileWriter()
    for i in range(pdf_reader.getNumPages()):
        page = pdf_reader.getPage(i)
        page.mergePage(watermark_reader.getPage(0))
        pdf_writer.addPage(page)
    with open(output_file, 'wb') as fh:
        pdf_writer.write(fh)
 
if __name__ == '__main__':
    input_file = r'C:\path\to\your\pdf\file.pdf'
    output_file = r'C:\path\to\your\output\watermarked.pdf'
    watermark_path = r'C:\path\to\your\watermark.pdf'
    add_watermark(input_file, output_file, watermark_path)

以上代码仅供参考，具体实现需根据实际需求进行调整和完善。
