Examples

Example #1 imagepalettecopy() example

<?php
// Create two palette images
$palette1 = imagecreate(100, 100);
$palette2 = imagecreate(100, 100);

// Allocate the background to be 
// green in the first palette image
$green = imagecolorallocate($palette1, 0, 255, 0);

// Copy the palette from image 1 to image 2
imagepalettecopy($palette2, $palette1);

// Since the palette is now copied we can use the 
// green color allocated to image 1 without using 
// imagecolorallocate() twice
imagefilledrectangle($palette2, 0, 0, 99, 99, $green);

// Output image to the browser
header('Content-type: image/png');

imagepng($palette2);
?>
