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);
?>
