If you pass "-1" into the last param of imagecreatefrompng, it preserves PNG transparently
properly!
Exampe:
<?php
$filename = './documents/135.pdf.png';
$degrees = 40;
header('Content-type: image/png');
$source = imagecreatefrompng($filename);
$rotate = imagerotate($source, $degrees, -1);
imagealphablending($rotate, true);
imagesavealpha($rotate, true);
imagepng($rotate);
?>
