# Features

A powerful Lottie animation theme converter that helps you easily switch between light and dark themes:

### ⚡ Color Inversion While Preserving Transparency

Smartly inverts colors of embedded images in Lottie files while maintaining alpha channel transparency.

### 🎨 Support for Both Light & Dark Themes  

Perfect for applications requiring both light and dark mode animations.

### 💻 Simple Python Implementation

Easy-to-understand Python script using only Pillow library for image processing.

### 🔄 Base64 Image Handling

Efficiently processes base64 encoded images embedded in Lottie JSON files.

## 🤔 How to Use

1. Install requirements:

```bash

pip install -r requirements.txt

```

2. Place your light theme Lottie animation file as "Animation-ClickMe.json"

3. Run the conversion script:

```python

python convert_lottie.py

```

pip install pillow==11.0.0

```

You can start converting your Lottie animation by following these steps:

1. Save your Lottie animation file as "Animation-ClickMe.json"

2. Run convert_lottie.py

3. The script will generate "Animation-ClickMe-dark.json" with inverted colors

## Learn More

The script processes embedded base64 images in the Lottie JSON file:

- Decodes base64 to image

- Inverts colors while preserving transparency 

- Re-encodes to base64

- Updates the Lottie JSON with new image data

Feel free to modify the code to work with different input/output filenames or add additional image processing features!
