What are the advantages and disadvantages of using GD-Lib for working with GIF images in PHP?

When working with GIF images in PHP, using the GD-Lib library can be advantageous as it provides functions for creating, manipulating, and outputting GIF images. However, GD-Lib has limitations compared to other libraries like Imagick, such as limited support for advanced image manipulation techniques and slower performance. It is important to weigh the pros and cons of using GD-Lib for GIF images based on the specific requirements of your project.

// Example code snippet using GD-Lib to create a GIF image
$width = 200;
$height = 200;
$image = imagecreate($width, $height);

$white = imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);

imageline($image, 0, 0, $width, $height, $black);

header('Content-type: image/gif');
imagegif($image);
imagedestroy($image);
