||||
- **Flip**: Flip images horizontally or vertically
|
||||
- **Convert**: Convert between different image formats
|
||||
|
||||
### Filters & Effects
|
||||

|
||||
- **Artistic Effects**: Apply artistic effects (sepia, grayscale, invert, posterize, solarize)
|
||||

||||
## Installation
|
||||
|
||||
### Option 1: Run from Source
|
||||
|
||||
1. Install Python 3.7 or higher
|
||||
2. Install dependencies:
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### Option 2: Use Pre-built Executable
|
||||
|
||||
1. Download the latest `pillow-cli.exe` from the releases
|
||||
2. Run directly without Python installation required
|
||||
|
||||
### Option 3: Build Your Own Executable
|
||||
|
||||
1. Install Python 3.7 or higher
|
||||
2. Install dependencies:
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
3. Build the executable:
|
||||
|
||||
```bash
|
||||
# Windows batch script
|
||||
build_exe.bat
|
||||
|
||||
# Or PowerShell script
|
||||
build_exe.ps1
|
||||
|
||||
# Or manually with PyInstaller
|
||||
pyinstaller pillow-cli.spec
|
||||
```
|
||||
|
||||
4. Find the executable in the `dist/` folder
|
||||
|
||||

|
||||
|
||||
### Example 1: Create a Social Media Post
|
||||
|
||||
1. Resize image to square format:

||||
```
|
||||
|
||||
### Example 2: Process Product Photos

||||
```
|
||||
|
||||
2. Create thumbnails:

||||
```
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Chaining Operations
|
||||
|
||||
You can chain multiple operations by using the output of one command as input to another:
|
||||
|
||||
```bash
|
||||
# First, resize the image
|
||||
python pillow-cli.py resize original.jpg resized.jpg --width 800
|
||||
|
||||
# Then apply a filter
|
||||
python pillow-cli.py filter resized.jpg filtered.jpg sharpen
|
||||
|
||||
# Finally, add a watermark
|
||||
python pillow-cli.py watermark filtered.jpg final.jpg "© 2025" --position bottom-right
|
||||
```
|
||||
|
||||
### Batch Processing Different Operations
|
||||
|
||||
Process different types of operations on batches:
|
||||
|
||||
```bash
|
||||
# Apply different effects
|
||||
python pillow-cli.py batch photos vintage_photos effect --effect-type sepia
|
||||
python pillow-cli.py batch photos bw_photos effect --effect-type grayscale
|
||||
|
||||
# Apply different filters
|
||||
python pillow-cli.py batch photos sharp_photos filter --filter-type sharpen
|
||||
python pillow-cli.py batch photos soft_photos filter --filter-type blur
|
||||
```
|
||||
|
||||

||||
The tool includes comprehensive error handling for:
|
||||
|
||||
- Invalid file paths
|
||||
- Unsupported image formats
|
||||
- Invalid crop dimensions
