Graphic Draw (GD)¶
GD is the name of a PHP extension that can manipulate several image formats, such as GIF, PNG, JPEG, WBMP, and XPM, and draw graphics.
<?php
// Creating a PNG image with PHP
// Extract from the PHP documentation
header("Content-type: image/png");
$string = $_GET['text'];
$im = imagecreatefrompng(images/button1.png);
$orange = imagecolorallocate($im, 220, 210, 60);
$px = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
?>
