Quick Start

Visual Designer Interface

The package includes a complete drag-and-drop visual designer for creating and editing templates:

1. Create a template via Filament or directly in the database
2. Click the "Designer" button on any template
3. Upload image elements (logos, stamps, decorations)
4. Drag and position elements on the canvas
5. Add text fields with positioning and styling
6. Preview your design in real-time
7. Generate the final composite image

Accessing the Designer:

// From Filament: Click "Designer" button on any template
// Or directly via route:
route('image-template.designer', ['template' => $templateId])

Basic Usage

use Badrshs\DynamicImageComposer\DynamicImageComposer;

$composer = new DynamicImageComposer();

// Generate image with text overlays
$image = $composer->generate(
    templatePath: 'templates/my-template.png',
    fields: [
        'name' => [
            'value' => 'John Doe',
            'x' => 'center',
            'y' => 500,
            'fontSize' => 60,
            'color' => 'black',
            'font' => 'default',
            'alignment' => 'center'
        ],
        'date' => [
            'value' => date('Y-m-d'),
            'x' => 100,
            'y' => 1000,
            'fontSize' => 30,
            'color' => 'gray',
            'font' => 'default'
        ]
    ]
);

// Save to storage
$result = $composer->save($image, 'output-' . time() . '.png');
// Returns: ['path' => '...', 'url' => '...', 'filename' => '...', 'disk' => '...']

// Or output directly as HTTP response
return $composer->output($image, 'my-image.png');

With Image Overlays

$image = $composer->generate('templates/base.png', [
    'title' => [
        'value' => 'Certificate of Achievement',
        'x' => 'center',
        'y' => 300,
        'fontSize' => 80,
        'color' => 'gold'
    ]
]);

// Add logo overlay
$composer->addOverlay($image, 'logos/company-logo.png', [
    'x' => 100,
    'y' => 100,
    'width' => 200,
    'height' => 200,
    'opacity' => 0.8
]);

return $composer->output($image);

Using Database Templates

use Badrshs\DynamicImageComposer\Models\ImageTemplate;

// Create a template
$template = ImageTemplate::create([
    'name' => 'My Certificate Template',
    'background_image' => 'templates/certificate-bg.png',
    'width' => 2480,
    'height' => 3508,
    'is_active' => true,
    'field_configuration' => [
        'fields' => [
            'name' => [
                'x' => 'center',
                'y' => 1200,
                'fontSize' => 100,
                'color' => 'black',
                'font' => 'monotype',
                'alignment' => 'center'
            ]
        ]
    ]
]);

// Generate from template
$composer = new DynamicImageComposer();
$image = $composer->generate(
    $template->background_image,
    array_merge(
        ['name' => ['value' => 'Jane Smith']],
        $template->field_configuration['fields'] ?? []
    )
);

Configuration

Edit config/dynamic-image-composer.php:

return [
    // Storage disk for templates and generated images
    'disk' => env('DYNAMIC_IMAGE_DISK', 'public'),
    
    // Directories
    'templates_directory' => 'image-templates',
    'elements_directory' => 'image-elements',
    'generated_directory' => 'generated-images',
    'fonts_directory' => 'fonts',
    
    // Font definitions (add your custom fonts)
    'fonts' => [
        'default' => [
            'en' => 'Museo500-Regular.ttf',
            'ar' => 'sky.ttf',
        ],
        // Add more fonts...
    ],
    
    // Color definitions (RGB values)
    'colors' => [
        'black' => [40, 40, 40],
        'white' => [255, 255, 255],
        'gold' => [212, 175, 55],
        // Add more colors...
    ],
];

Field Configuration

Each field supports these options:

Filament Integration (Optional)

If you're using Filament, register the resource in your panel:

use Badrshs\DynamicImageComposer\Filament\Resources\ImageTemplateResource;

public function panel(Panel $panel): Panel
{
    return $panel
        ->resources([
            ImageTemplateResource::class,
        ]);
}

This provides a full admin interface for managing templates and elements, including:

• Template CRUD operations
• Visual designer interface
• Element management
• Live preview generation

Displaying Generated Images

Use the included Blade component to display generated images in a grid:

<x-dynamic-image-composer::generated-images-grid 
    :images="$generatedImages"
    itemLabel="Certificate"
/>

Where $generatedImages is an array of:

[
    [
        'url' => 'https://...',
        'name' => 'John Doe',
        'filename' => 'certificate.png',
        'metadata' => 'Generated on 2024-01-01' // optional
    ],
    // ...
]

Advanced Usage

Custom Fonts

Add custom fonts to your public/fonts directory or storage, then register them in config:

'fonts' => [
    'my-font' => [
        'en' => 'MyFont-Regular.ttf',
        'ar' => 'MyFont-Arabic.ttf',
    ],
],

Custom Colors

Add custom colors in config:

'colors' => [
    'brand-blue' => [30, 144, 255],
    'brand-red' => [220, 53, 69],
],

Arabic Text Support

The package automatically detects and handles Arabic text:

$image = $composer->generate('template.png', [
    'name' => [
        'value' => 'محمد أحمد', // Arabic text
        'x' => 'center',
        'y' => 500,
        'fontSize' => 60,
        'font' => 'default', // Will use Arabic font variant
    ]
]);
