Small example to optimize a gray scanned image:
<?php
   $im
= new Imagick();
  
$im->readImage("~/scaninput_300DPI.tiff");
 
//deskew the image
  
$im->deskewImage(40);
 
//Crop to A4 and scanner pageoffset 50
  
$im->cropImage(2480, 3416, 50, 0);
 
//Need a Monochrome Image
  
$im->setImageColorspace(2);
  
$im->thresholdImage(11000);
 
//Compressen tiff CCITT Group 4
  
$im->setImageCompression(Imagick::COMPRESSION_GROUP4);
  
$im->writeimage("~/monochrome_300DPI.tiff");
 
//Cleanup  
  
$im->clear();
  
$im->destroy();
