Are there any specific PHP libraries or functions that are more suitable for analyzing color patterns in images compared to ImageMagick?

When analyzing color patterns in images, the PHP library GD can be more suitable than ImageMagick due to its simplicity and direct access to pixel data. GD provides functions like imagecolorat() and imagecolorsforindex() that can be used to extract color information from specific pixels in an image. 

// Load the image using GD
$image = imagecreatefromjpeg('image.jpg');

// Get the color of a specific pixel
$color_index = imagecolorat($image, 100, 100);
$rgb = imagecolorsforindex($image, $color_index);

// Output the RGB values
echo 'Red: ' . $rgb['red'] . '<br>';
echo 'Green: ' . $rgb['green'] . '<br>';
echo 'Blue: ' . $rgb['blue'] . '<br>';

// Free up memory
imagedestroy($image);
