A simple, lightweight and fast PHP function that uses the GD library to extract the average color of an image.
- Include the function in your PHP script:
require_once 'imgextractor.php';- Call the function by passing the path to the image file as the argument:
$avgColor = getAvgColor('path/to/image.<any image extension>');- The function will return the average color of the image as a hex value, for example:
#ff0000
<?php
require_once('imgextractor.php');
$img_url ="https://cdn.pixabay.com/photo/2013/07/21/13/00/rose-165819__340.jpg";
?>
<body>
<img src=<?php echo $img_url; ?>>
<style>
body {
background-color: <?php echo getAvgColor($img_url) ?>;
}
</style>
</body>Keep in mind that this function will return the average color of an image, not the main color. Also it's a simple implementation, it may not be the best solution for all cases.
