# Image Tools


Collection of bash scripts for image processing and optimization.

## Scripts

### optimize-png.sh

Script to minimize PNG images

**Usage:**
```bash
./optimize-png.sh [colors] file1.png file2.png ...
./optimize-png.sh [colors] *.png
```
Or select files in Nemo file manager and run as script

**Parameters:**
- `colors` - Number of colors (8-256, default: 256)
- `files` - PNG files to minimize

**Examples:**
```bash
./optimize-png.sh image1.png image2.png    # Minimize specific files with 256 colors
./optimize-png.sh 128 *.png                # Minimize all PNG files with 128 colors
./optimize-png.sh 64 graphics/*.png        # Minimize PNG files in graphics folder
```

**Features:**
- Minimized images will be saved in the 'min' subdirectory
- When used as Nemo script, a dialog will ask for colors
- Dual-mode operation (GUI/Terminal)
- Progress tracking and batch processing
- Quality control with color reduction

**Dependencies:**
- `pngquant` for PNG optimization
- `zenity` for GUI dialogs (usually pre-installed)

### optimize-jpg.sh

Script to compress JPG images

**Usage:**
```bash
./optimize-jpg.sh [quality] file1.jpg file2.jpg ...
./optimize-jpg.sh [quality] *.jpg
```
Or select files in Nemo file manager and run as script

**Parameters:**
- `quality` - Compression quality (1-100, default: 90)
- `files` - JPG/JPEG files to compress

**Examples:**
```bash
./optimize-jpg.sh photo1.jpg photo2.jpg    # Compress specific files with quality 90
./optimize-jpg.sh 85 *.jpg                 # Compress all JPG files with quality 85
./optimize-jpg.sh 75 vacation/*.jpeg       # Compress JPEG files in vacation folder
```

**Features:**
- Compressed images will be saved in the 'min' subdirectory
- When used as Nemo script, a dialog will ask for quality
- Dual-mode operation (GUI/Terminal)
- Progress tracking and batch processing
- Quality control with compression levels

**Dependencies:**
- `imagemagick` for JPG compression (mogrify command)
- `zenity` for GUI dialogs (usually pre-installed)

## Installation

1. Install dependencies:
```bash
sudo apt install pngquant imagemagick  # Ubuntu/Debian
sudo dnf install pngquant ImageMagick  # Fedora
# Note: zenity is usually pre-installed with desktop environments
```

2. Make scripts executable:
```bash
chmod +x *.sh
```

3. For use as Nemo scripts, copy to:
```bash
~/.local/share/nemo/scripts/
```

## Notes

All scripts support dual-mode operation:
- **Terminal mode**: When run from command line
- **GUI mode**: When run as Nemo file manager scripts with zenity dialogs

Both scripts create a 'min' subdirectory for optimized output files to preserve originals.
