# Pixel Forge 🎨

> The complete image generation toolkit for modern web development

Pixel Forge is a reliable TypeScript package that generates optimized images for social media previews, favicons, SEO metadata, and PWA assets across **all major platforms** - from Facebook and Instagram to TikTok, WhatsApp, Discord, to iMessage, SMS, RCS, and more.

**Built with ImageMagick for rock-solid reliability across all environments.**

✨ **Enhanced with advanced transparency preservation techniques for perfect RGBA handling.**

*Stop wrestling with image sizes. Start focusing on your content.* 

**Perfect for web developers who want everything needed for modern web applications in one command.**

## 🚀 Quick Start

### Prerequisites

Pixel Forge requires ImageMagick to be installed on your system:

```bash
# macOS
brew install imagemagick

# Ubuntu/Debian
sudo apt-get install imagemagick

# Windows (using Chocolatey)
choco install imagemagick

# Or download from: https://imagemagick.org/script/download.php
```

### No Installation Required!

```bash
# Run directly with npx (recommended)
npx pixel-forge generate logo.png --web
```

### Generate Everything for Your Website

```bash
# Generate all web assets (favicon, PWA, SEO)
npx pixel-forge generate logo.png --web

# Or use the short alias
npx pforge generate logo.png --web
```

### Quick Usage Examples

```bash
# Initialize configuration
npx pixel-forge init

# Generate favicons only
npx pixel-forge generate logo.png --favicon

# Generate PWA assets
npx pixel-forge generate logo.png --pwa

# Generate SEO images
npx pixel-forge generate logo.png --seo

# Generate specific social media images
npx pixel-forge generate logo.png --platform facebook,instagram,tiktok

# Generate everything
npx pixel-forge generate logo.png --all
```

### Optional: Install Globally

```bash
# For frequent use, install globally
npm install -g pixel-forge

# Then use without npx
pixel-forge generate logo.png --web
```

### Programmatic Usage

```typescript
import { PixelForgeConfig, generateAll } from 'pixel-forge';

const config: PixelForgeConfig = {
  input: './logo.png',
  outputDir: './assets',
  // ... other options
};

await generateAll(config);

## 🔧 Technical Details

### **Advanced Transparency Preservation**

Our implementation uses cutting-edge ImageMagick techniques discovered through extensive debugging:

- **`-define png:color-type=6`** - Forces RGBA format, prevents 8-bit colormap conversion
- **`-define png:bit-depth=8`** - Ensures proper bit depth for transparency
- **`-filter lanczos`** - High-quality resampling preserves transparency edges
- **`-background none`** - Proper transparent background handling during resize operations

This eliminates the common "black background" problem that occurs when transparency information is lost during image processing.
