What are the advantages of using OOP principles when working with PHP GD for text output?

When working with PHP GD for text output, using Object-Oriented Programming (OOP) principles can help organize your code, improve reusability, and make it easier to maintain and extend in the future. By encapsulating functionality into classes and objects, you can create a more modular and structured approach to generating text output with PHP GD. 

<?php

class TextOutputGenerator {
    private $image;
    private $font;
    
    public function __construct($width, $height) {
        $this->image = imagecreate($width, $height);
        $this->font = 'arial.ttf';
    }
    
    public function generateText($text, $x, $y, $size, $color) {
        $textColor = imagecolorallocate($this->image, $color[0], $color[1], $color[2]);
        imagettftext($this->image, $size, 0, $x, $y, $textColor, $this->font, $text);
    }
    
    public function outputImage() {
        header('Content-Type: image/png');
        imagepng($this->image);
        imagedestroy($this->image);
    }
}

// Example usage
$outputGenerator = new TextOutputGenerator(400, 200);
$outputGenerator->generateText('Hello World', 50, 100, 20, [255, 0, 0]);
$outputGenerator->outputImage();
?>
