Python method to convert pdf to image

Below I will share with you a Python method to convert pdf into pictures. It has a good reference value and I hope it will be helpful to everyone. Let’s take a look together

This article records how to use Python to split a PDF file into pictures, including environment configuration and version compatibility issues.

Environment configuration (mac)

Install ImageMagick

brew install imagemagick

There is a pit here , brew installations are all version 7.x. When using wand, an error will occur, and you need to install version 6.x.

Solution:

1. Install version 6.x

brew install imagemagick@6

2. Unlink 7.x version

brew unlink imagemagick
Unlinking /usr/local/Cellar/imagemagick/7.0.7-4… 71 symlinks removed

3. Force link to 6.x version

 brew link imagemagick@6 --force
Linking /usr/local/Cellar/imagemagick@6/6.9.9-15… 75 symlinks created

4 .export environment variable

echo 'export PATH="/usr/local/opt/imagemagick@6/bin:$PATH"' >> ~/.bash_profile

ok, the above solves the imagemagick version problem.

Install gs

Must install gs, otherwise pdf cannot be converted.

brew install gs

Install wand

pip3 install wand

I am using python3 here, so I need to use pip3.

Code implementation

from wand.image import Image
def convert_pdf_to_jpg(filename):
 with Image(filename=filename) as img :
  print('pages = ', len(img.sequence))
  with img.convert('jpeg') as converted:
   converted.save(filename='image/page.jpeg')

Effect
