What are the drawbacks of using pre-existing classes for generating security code images in PHP?

Using pre-existing classes for generating security code images in PHP may have drawbacks such as limited customization options, potential security vulnerabilities, and compatibility issues with future PHP versions. To solve this, consider creating a custom function to generate security code images that meets your specific requirements and ensures better control over the security of the generated images. 

function generateSecurityCodeImage($code) {
    $image = imagecreatetruecolor(100, 50);
    $bgColor = imagecolorallocate($image, 255, 255, 255);
    $textColor = imagecolorallocate($image, 0, 0, 0);
    
    imagefill($image, 0, 0, $bgColor);
    imagettftext($image, 20, 0, 10, 30, $textColor, 'arial.ttf', $code);
    
    header('Content-type: image/png');
    imagepng($image);
    imagedestroy($image);
}

$securityCode = 'ABCD1234';
generateSecurityCodeImage($securityCode);
