Lock Screen Wallpaper Generator

This project generates a custom wallpaper for your lock screen that matches the appearance of your password screen. It consists of four Python scripts and a configuration file.

Prerequisites

Python 3 or higher
Pillow library

Install the required library using:

pip install pillow

Usage

Replace the images in the input folder with your own images. Make sure to name them correctly:
- source/original.jpg: The source image you want to use as a wallpaper.
- lockscreen/lockscreen.png: A screenshot of your lock screen without the password prompt.
- lockscreen/password.png: A screenshot of your lock screen with the password prompt visible.
Run the following scripts in order:
- Generate the calibration pattern
```
python generate_pattern.py
```
  1. Replace your lock screen wallpaper with the generated image. Default location: backgrounds/background_pattern.jpg
  2. Replace your profile picture with the black image. Default location: backgrounds/black.jpg
  3. Take a screenshot of your lock screen. The plain and with password prompt. Save them as lockscreen/lockscreen.png and lockscreen/password.png respectively.
    - To take screenshots, you can use snipping tool on Windows. Set it as Rectagle mode then add some delay.
    - Then click new and lock your screen.
- Calculate the difference between the lock screen and the password prompt If your windows doesn't have Zoom effect, you can skip this step.
```
python diff.py
```
  This will calculate the difference between the lock screen and the password prompt.
- Generate the profile image
```
python generate_profile.py
```
  Let the magic happen. This will generate the profile image.
  Arguments
  - --tint TINT: Tint percentage (float) to apply (default: 0)
  - --auto-tint: Automatically detect tint percentage from the source image
  - --sample-area X1 Y1 X2 Y2: Sample area for automatic tint detection (default: 200, 200, 400, 400). Provide 4 integers as coordinates.
  - --mask: Create a mask from the lock screen image
  - --circle: Create a mask as a circle from the lock screen image
  - --scale SCALE: Increase or decrease the size of the mask scale percentage (default: 100)
The generated profile will be saved in result/result.jpg. Apply this image as your lock screen wallpaper.
During the process, there are additional images created :
- backgrounds/pattern_lock_screen.png: A patterned image that mimics the border design of the lock screen.
- source/cropped.jpg: The cropped source image.
- source/resized.jpg: The resized source image.

Configuration

You can customize the input and output paths of your project in the config.json file. Modify the paths as needed.

{
  "input": {
    "source": "source/original.jpg",
    "lockscreen": "lockscreen/lockscreen.png",
    "password": "lockscreen/password.png"
  },
  "output": {
    "pattern": "backgrounds/pattern_lock_screen.png",
    "result": "result/result.jpg",
    "source_cropped": "source/cropped.jpg",
    "source_resized": "source/resized.jpg"
  }
}

How it works

generate_pattern.py: This script creates a reference pattern image based on the source image dimensions.
diff.py: This script finds the differences between the lock screen and password screen images and resizes the source image accordingly.
generate_profile.py: This script creates a mask from the lock screen password image and applies it to the resized source image to generate the final wallpaper.
