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:





<?php


header('content-type: image/jpeg');


$imagick = new Imagick();


$imagick->readImage('castle.jpg');


$imagick->rotateImage(new ImagickPixel(), 90);


print $imagick->getImage();


?>
