The script I just made is to solve the problem where I have to resize the photo, that I capture using my iPhone, and convert it from HEIC to JPG. The purpose is to upload the photos to this blog post and to make sure the photos are not taking too much disk space from the server. It’s taking too many steps and if I have many photos it will take time to do replicated stuff. Therefore I decided to write a script that took me only 15 minutes to search for the pieces of the script in Stackoverflow. Below are the steps or thought processes that I want to do to construct the scripts:
- List the images: to be read and executed later
- Create output directories: one for converted jpg images, another for the resized jpg images
- Loop through the input HEIC images, and convert them to JPG
- From the outputted JPG, resize and save them.
To understand the codes. First, we need to make sure we have the required dependencies.
Setup the environment
I am using python 3.11 and pillow. Initially I was planning to use OpenCV but Pillow is actually good enough.
Read the input files
Read the input files, in this example I’m going to save the input HEIC images in images directory. Then we should only read the images from there with the extension of HEIC only
Create output directories
Convert HEIC to JPG
We loop through the file name in the list variable files . Use Pillow to do the magic
Resize JPG with a ratio
We want to have width and height no bigger than a specific size then we use Pillow to do the magic also
And that is. The output structure of the code directory should be something like this
