Be cautious and set bgcolor BEFORE importing a SVG with transparency!  :-/





<?php





$im = new Imagick();


$im->setBackgroundColor(new ImagickPixel('transparent'));





$im->readImage('carte_Alain2.svg');





$im->setImageFormat("png32");





header('Content-type: image/png');


echo $im;


?>
