Generate PDF from HTML File

use GeneratePDFs\GeneratePDFs;
use GeneratePDFs\Pdf;

// Simple HTML file
$pdf = $client->generateFromHtml('/path/to/file.html');

// HTML file with CSS
$pdf = $client->generateFromHtml(
    '/path/to/file.html',
    '/path/to/file.css'
);

// HTML file with CSS and images
$pdf = $client->generateFromHtml(
    '/path/to/file.html',
    '/path/to/file.css',
    [
        [
            'name' => 'logo.png',
            'path' => '/path/to/logo.png',
            'mime_type' => 'image/png' // Optional, will be auto-detected
        ],
        [
            'name' => 'photo.jpg',
            'path' => '/path/to/photo.jpg'
        ]
    ]
);

Generate PDF from URL

$pdf = $client->generateFromUrl('https://example.com');

Get PDF by ID

// Retrieve a PDF by its ID
$pdf = $client->getPdf(123);

Working with PDF Objects

The SDK returns Pdf objects that provide easy access to PDF information and downloading:

// Access PDF properties
$pdfId = $pdf->getId();
$pdfName = $pdf->getName();
$status = $pdf->getStatus();
$downloadUrl = $pdf->getDownloadUrl();
$createdAt = $pdf->getCreatedAt();

// Check if PDF is ready
if ($pdf->isReady()) {
    // Download PDF content as string
    $pdfContent = $pdf->download();
    
    // Or save directly to file
    $pdf->downloadToFile('/path/to/save/output.pdf');
}

// Refresh PDF data from the API (useful for checking status updates)
$refreshedPdf = $pdf->refresh();
if ($refreshedPdf->isReady()) {
    $pdfContent = $refreshedPdf->download();
}
