You can rotate an jpg image by -13.55° into a transparent png image with :

<?php
$imagick
= new Imagick();
$imagick->readImage('my.jpg');
$imagick->rotateImage(new ImagickPixel('none'), -13.55);
$imagick->writeImage('my_rotated.png');
$imagick->clear();
$imagick->destroy();
?>

If you want to rotate an image by a certain degree you can do this:

header
('content-type: image/jpeg');
$imagick = new Imagick();
$imagick->readImage('castle.jpg');
$imagick->rotateImage(new ImagickPixel(), 90);
print
$imagick->getImage();
?>
