🚀 Quick Start

Basic Usage

Generate an avatar with just a few lines:

use Renfordt\AvatarSmithy\Avatar;

// Simple avatar with email seed
$avatar = Avatar::engine('initials')
    ->seed('john.doe@example.com')
    ->name('John Doe')
    ->generate();

echo $avatar; // Outputs HTML img tag

Smart User Factory

Automatically extract email and name from user objects or arrays:

// Works with objects
$user = new User(['email' => 'jane@example.com', 'name' => 'Jane Smith']);
$avatar = Avatar::for($user)
    ->try('initials')
    ->size(300)
    ->generate();

// Works with arrays
$userData = ['email' => 'bob@example.com', 'name' => 'Bob Wilson'];
$avatar = Avatar::for($userData)
    ->try('gravatar')
    ->fallbackTo('initials')
    ->generate();

Fallback Chain

Create a robust avatar system with automatic fallbacks:

$avatar = Avatar::engine('gravatar')
    ->fallbackTo('dicebear')
    ->fallbackTo('initials')  // Final fallback always succeeds
    ->seed('user@example.com')
    ->name('User Name')
    ->size(256)
    ->generate();

🎨 Available Engines

Engine	Description	Network	Example Use Case
initials	SVG avatars with user initials in colored shapes	❌	Default user profiles
gravatar	Fetches from Gravatar.com based on email hash	✅	Blog comments, social platforms
dicebear	Fetches from DiceBear API (various styles)	✅	Fun, cartoon-style avatars
pixel	Generates retro pixel-art style avatars	❌	Gaming platforms, retro themes
multicolor-pixel	Multi-colored variant of pixel engine	❌	Vibrant pixel art avatars
bauhaus	Bauhaus-inspired geometric art avatars	❌	Modern, artistic profiles
gradient	Beautiful gradient-based avatars	❌	Minimalist, colorful designs

💡 Tip: Engines marked with ❌ generate avatars locally without network requests, while ✅ engines fetch from external APIs.

📤 Output Formats

AvatarSmithy provides multiple output formats for maximum flexibility:

HTML Image Tag $avatar->toHtml(); // <img src="data:image/svg+xml;base64,..." // alt="Avatar">	Base64 Data URI $avatar->toBase64(); // data:image/svg+xml;base64, // PHN2ZyB3aWR0aD0iMjAwIi...
URL or Raw Content $avatar->toUrl(); // Gravatar: https://gravatar.com/... // Local: data:image/svg+xml;base64,...	PSR-7 HTTP Response // In a Laravel/Symfony controller return Avatar::for($user) ->try('gravatar') ->fallbackTo('initials') ->toResponse();
Direct String Conversion echo $avatar; // Auto-converts to HTML img tag	Save to File $avatar->save('/path/to/avatar.svg'); // Saves avatar to filesystem

⚙️ Configuration Options

Universal Options

These options work across all engines:

Avatar::engine('initials')
    ->seed('unique-identifier')      // Seed for deterministic generation
    ->name('John Doe')                // User's display name
    ->size(200)                       // Avatar size in pixels (default: 200)
    ->generate();

Engine-Specific Options

Initials Engine

Avatar::engine('initials')
    ->name('John Doe')
    ->size(256)
    ->shape('circle')                 // 'circle' or 'square'
    ->bold(true)                      // Bold font weight
    ->fontSize(100)                   // Custom font size
    ->backgroundColor(['#FF6B6B', '#4ECDC4', '#45B7D1'])  // Color palette
    ->generate();

Gravatar Engine

Avatar::engine('gravatar')
    ->seed('user@example.com')        // Email address
    ->size(256)
    ->defaultImage('identicon')       // '404', 'mp', 'identicon', 'monsterid',
                                      // 'wavatar', 'retro', 'robohash', 'blank'
    ->rating('g')                     // 'g', 'pg', 'r', 'x'
    ->generate();

DiceBear Engine

Avatar::engine('dicebear')
    ->seed('user@example.com')
    ->size(256)
    ->style('avataaars')              // DiceBear style (e.g., 'avataaars', 'bottts')
    ->backgroundColor('#FF6B6B')      // Hex color
    ->radius(10)                      // Border radius
    ->generate();

Pixel Engines

// Single color pixel
Avatar::engine('pixel')
    ->seed('user@example.com')
    ->size(256)
    ->pixels(5)                       // Grid size (5x5 pixels)
    ->symmetry(true)                  // Mirror horizontally
    ->foregroundLightness(0.4)        // Lightness of colored pixels (0.0-1.0)

Avatar::engine('bauhaus')
    ->seed('user@example.com')
    ->size(256)
    ->numShapes(5)                    // Number of geometric shapes
    ->numColors(3)                    // Color palette size
    ->fillAll(false)                  // Whether to fill entire canvas
    ->generate();

Gradient Engine

Avatar::engine('gradient')
    ->seed('user@example.com')
    ->size(256)
    ->gradientType('linear')          // 'linear' or 'radial'

    ->generate();

💎 Advanced Examples

Laravel Integration

// routes/web.php
Route::get('/avatar/{user}', function (User $user) {
    return Avatar::for($user)
        ->try('gravatar')
        ->fallbackTo('initials')
        ->size(400)
        ->toResponse();
});

// In a Blade template
<img src="{{ route('avatar', $user) }}" alt="{{ $user->name }}">

Custom Styling with Fallback Chain

$avatar = Avatar::for($user)
    ->try('gravatar')
    ->fallbackTo('dicebear')
    ->fallbackTo('initials')
    ->size(300)
    ->defaultImage('404')             // Gravatar: fail if not found
    ->style('avataaars')              // DiceBear: cartoon style
    ->shape('circle')                 // Initials: circular shape
    ->bold(true)                      // Initials: bold text
    ->generate();

Batch Generation

$users = User::all();
$avatars = [];

foreach ($users as $user) {
    $avatars[$user->id] = Avatar::for($user)
        ->try('initials')
        ->size(150)
        ->generate()
        ->toBase64();
}

Dynamic Engine Selection

function generateAvatar(array $user, string $preferredEngine = 'initials'): string
{
    return Avatar::for($user)
        ->try($preferredEngine)
        ->fallbackTo('initials')
        ->size(200)
        ->generate()
        ->toHtml();
}

// Usage
echo generateAvatar($user, 'pixel');
echo generateAvatar($adminUser, 'gravatar');
