What worked for me to convert a JPG source file to a semi-transparent PNG.



<?php

    $srcImagick = new Imagick($srcPath);

    

    $pathTo50Perc = 'transparent1.png';

    

    $srcImagick->setImageAlphaChannel(Imagick::ALPHACHANNEL_OPAQUE);

    

    $srcImagick->evaluateImage(Imagick::EVALUATE_DIVIDE, 2, Imagick::CHANNEL_ALPHA);



    $srcImagick->writeImage($pathTo50Perc);

?>
