GD Rotate not working

Im trying to simply rotate some text by 15 degrees, but I cant get it working at all despite multiple debug lines

My simplified code I dont think I could get more simpler, what Ive done is:-

<?php
header('Content-Type: image/png');

$im = imagecreatetruecolor(300, 150);
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);

imagefilledrectangle($im, 0, 0, 300, 150, $white);

$text = 'Testing...';
$font = 'arial.ttf';

imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

imagerotate($im, 15, 0);

imagepng($im);
imagedestroy($im);
?>

Open in new window

Any idea what Im doing wrong?

No points for this, please, but when in doubt it's always wise to check the online man pages. I could not work without a window open to PHP.net at all times. In the instant case you can see that the imagerotate() function returns a resource.
http://php.net/manual/en/function.imagerotate.php

I can see how this can be confusing, since many of the other image functions mutate a resource and return something like a boolean, but that is the unfortunate nature of PHP - it's hard to guess what will be changed or returned without reference to the manual. Example of a related function:

Hi,

Try installing "imagick" and restarted apache.
