Python中将图像转换为PDF的方法实现

pip install img2pdf PyPDF2 Pillow 

# required libraries
import os
import img2pdf

from PIL import Image
from google.colab import files

pip install img2pdf

# Python3 program to convert image to pdf

# using img2pdf library
# importing necessary libraries

# storing image path

# opening image

# converting into chunks using img2pdf
pdf_bytes = img2pdf.convert(image.filename)
# opening or creating pdf file
file = open(pdf_path, "wb")
# writing pdf files with chunks
file.write(pdf_bytes)
# closing image file
image.close()
# closing pdf file
file.close()
# output
print("Successfully made pdf file")
