python将图片转换为pdf

您可以使用Python的PyPDF2库将图像转换为PDF。以下是一个示例代码：

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

def convert_images_to_pdf(images, output_file):
    pdf_writer = PdfFileWriter()
    for image in images:
        image_file = BytesIO()
        image.save(image_file, 'JPEG')
        pdf_writer.addPage(
            PdfFileReader(BytesIO(image_file.getvalue())).getPage(0))
    with open(output_file, 'wb') as out:
        pdf_writer.write(out)

if __name__ == '__main__':
    image_folder = '/path/to/folder/containing/images'
    output_file = '/path/to/output/pdf/file.pdf'
    images = []
    for filename in os.listdir(image_folder):
        if filename.endswith('.jpg') or filename.endswith('.jpeg'):
            image = Image.open(os.path.join(image_folder, filename))
            images.append(image)
    convert_images_to_pdf(images, output_file)

这将读取指定文件夹中的所有JPEG图像，并将它们添加到PDF文件中。请注意，您需要安装Pillow库（即PIL库的分支）来处理图像，并且需要安装PyPDF2库来处理PDF。
