to create an animation gif  from filelist using addImage



<?php

    $filelist = array("fileitem1.png","fileitem2.png","fileitem3.png");



    $aniGif = new Imagick();

    $aniGif->setFormat("gif");



    foreach($filelist as $frameitem){

        echo "-----------------------\n adding frame {$frameitem}\n";

        $frame = new Imagick($frameitem);        

        $aniGif->addImage($frame);

        //$delay time unit is micro second so 100 = 1s, one picture per second

        $aniGif->setImageDelay($delay = 100);

        echo "end of adding frame {$frameitem}\n";

    }

    //there more than one file, so must be using writeImages()

    $aniGif->writeImages($fileTarget = "aniGif.gif", $adjoin = true);

?>
