    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');

    ?>
