python如何将图片读入pdf

文件中？

您可以使用Python的Pillow库来读取图片文件，然后使用PyPDF2库将其添加到PDF文件中。以下是一个简单的实现示例：

from PIL import Image
import os
from io import BytesIO
from PyPDF2 import PdfFileWriter, PdfFileReader

def add_image_to_pdf(image_path, pdf_path, output_path):
    with open(pdf_path, 'rb') as f:
        input_pdf = PdfFileReader(f)
        output_pdf = PdfFileWriter()

        for page_num in range(input_pdf.getNumPages()):
            page = input_pdf.getPage(page_num)
            output_pdf.addPage(page)

            if page_num == 0:
                image = Image.open(image_path)
                bio = BytesIO()
                image.save(bio, format='png')
                image_obj = bio.getvalue()
                output_pdf.addPage(PdfFileReader(BytesIO(image_obj)).getPage(0))

        with open(output_path, 'wb') as f:
            output_pdf.write(f)

image_path = 'path/to/image.png'
pdf_path = 'path/to/pdf.pdf'
output_path = 'path/to/output.pdf'

add_image_to_pdf(image_path, pdf_path, output_path)

请注意，此代码仅插入单个图像到PDF的第一页中。如需将多个图像插入PDF文件中，请进行修改以适应您的需求。
