create a favicon.ico with multiple resolutions

<?php

$src_img = new Imagick("src_img.png");
$icon = new Imagick();
$icon->setFormat("ico");

$geo=$src_img->getImageGeometry();

$size_w=$geo['width'];
$size_h=$geo['height'];

if (128/$size_w*$size_h>128) {
  $src_img->scaleImage(128,0);
} else {
  $src_img->scaleImage(0,128);
}

$src_img->cropImage(128, 128, 0, 0);

$clone = $src_img->clone();
$clone->scaleImage(16,0);           
$icon->addImage($clone);

$clone = $src_img->clone();
$clone->scaleImage(32,0);           
$icon->addImage($clone);

$clone = $src_img->clone();
$clone->scaleImage(64,0);

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);
?>
