}

$gmagick = new Gmagick();
$gmagick->newImage(500, 500, 'White');
$gmagick->setImageFormat("png");

$gmagick->drawImage($draw);

// Display the output image
header("Content-Type: image/png");
echo $gmagick->getImageBlob();
?>

Output:

$draw->setFontSize(40);

$gmagick = new Imagick();
$gmagick->newImage(900, 500, 'White');
$gmagick->setImageFormat("png");

// Annotate image
$gmagick->annotateImage($draw, 5, 120, 0,
        'GeeksforGeeks: A computer science portal');
