Python使用reportlab生成带有图片的pdf

  • reportlab是一个很好用的Python第三方库，可惜文档是纯英文的。
  • 下面是一个导出图片的简单示例
# -*- coding: utf-8 -*-

from reportlab.platypus import Image
from reportlab.pdfgen import canvas


def to_pdf(response, url_list=None):
    can = canvas.Canvas(response)

    url_list.sort(key=lambda x: x['page_num'])
    for url in url_list:
        image_url = url['image_url']
        image = Image(image_url)
        image_height = image.drawHeight
        image_width = image.drawWidth
        can.setPageSize((image_width, image_height))
        can.drawImage(image_url, 0, 0, image_width, image_height, 'auto')
        can.showPage()

    can.save()
    return response


if __name__ == "__main__":
    urls = [
        {"page_num":2 ,"image_url": "image_url"},
        {"image_url": "image_url", 'page_num': 1}
    ]

    port = to_pdf('test.pdf', urls)
