将多页PDF转换为TIFF不适用于Python库Wand

import os
from PyPDF2 import PdfFileReader
from PIL import Image

def convert_pdf_to_tiff(pdf_path, output_folder):
    # 创建输出文件夹
    os.makedirs(output_folder, exist_ok=True)

    # 读取PDF文件
    with open(pdf_path, 'rb') as file:
        pdf = PdfFileReader(file)
        num_pages = pdf.getNumPages()

        # 遍历每一页
        for page_num in range(num_pages):
            # 读取当前页
            page = pdf.getPage(page_num)

            # 将当前页保存为图像文件
            image_path = os.path.join(output_folder, f'page_{page_num}.png')
            page.exportToPng(image_path)

            # 将图像文件转换为TIFF格式
            image = Image.open(image_path)
            tiff_path = os.path.join(output_folder, f'page_{page_num}.tiff')
            image.save(tiff_path, format='TIFF')

            # 删除临时的图像文件
            os.remove(image_path)

    print('PDF转换为TIFF完成！')

# 示例用法
pdf_path = 'path/to/input.pdf'
output_folder = 'path/to/output'
convert_pdf_to_tiff(pdf_path, output_folder)
