<?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);
