The second parameter, $COMPOSE, has 3 usable values:

1 = the image is displayed normally;
2 = the image is displayed on a white background;
3 = the image is display in black on a white background;

Quick script for stamping a small image on a large image

#!/usr/bin/php
<?php
//  <wallace@wallacelau.com>
//Instantiate a new Gmagick object
$imgMain = new Gmagick('Torso_F.tiff');

// get the image width
$width = (int) ($imgMain->getimagewidth() /2) - 150;

//Instantiate a barcode img Gmagick object
$imgBarcode = new Gmagick('barcode.jpeg');

//stamp the barcode on top of the Main image
$imgMain->compositeimage($imgBarcode, 1, $width, 150);
//Write the current image at the current state to a file
$imgMain->write('withBarcode.tiff');
