PNG creation with PHP

Example #1 PNG creation with PHP


("Content-type: image/png");
$string $_GET['text'];
$im     imagecreatefrompng("images/button1.png");
$orange imagecolorallocate($im22021060);
$px     = (imagesx($im) - 7.5 strlen($string)) / 2;

This example would be called from a page with a tag like: <img src="button.php?text=text">. The above button.php script then takes this "text" string and overlays it on top of a base image which in this case is "images/button1.png" and outputs the resulting image. This is a very convenient way to avoid having to draw new button images every time you want to change the text of a button. With this method they are dynamically generated.

Keep in mind that transparency is not preserved when doing what is shown in Example #1 to a PNG with transparency.
