The example of this article describes the method of combining Python with ImageMagick to merge multiple pictures into one pdf file. I share it with you for your reference. The details are as follows:

I bought a lot of books some time ago, and now I have more and more books on hand. The space in the small rented house in Beijing is getting fuller and fuller. Since I got used to the gesture operation of the laptop touchpad, I even find it quite enjoyable to use the computer to read electronic documents. So I wanted to use my mobile phone to take pictures of some of my books, and then merge them into a pdf file.

I initially tried to find mature Windows software, but I never found one that was easy to use. I wanted to write a script for processing, but it has never been realized. I accidentally checked the instructions of ImageMagick software and found a method to batch merge. So, this function can finally be easily implemented.

Write a simple little script:

import os
defCompressImage(image_name):
  os.system("convert -resize\"600x800>\" %s %s" % (image_name,image_name))
def CompressAll():
  ext_names = ['.JPG','.jpg','.jepg']
  for each_image in os.listdir('./'):
    for ext_name in ext_names:
      ifeach_image.endswith(ext_name):
        CompressImage(each_image)
        break
CompressAll()
os.system("convert*.JPG book.pdf")

After the script is run, a pdf file is generated. Open the file as follows:

# As can be seen from the above results, the function of batch synthesizing PDF files of images has been implemented. Naturally, you need to consider the ordering of files when compositing. You can check the sorting rules later and rename the files.
