title: php imagettftext line height
body: <p>I have successfully written text to my <code>img</code> and positioned it correctly, however the problem I have ran into is that increasing the font size makes the text go off the image.</p>
  
  <p>So I know I can achieve the look I want by just simply increasing the line height of the text writing to the screen. I can't seem to find any documentation on if/how this can be done.</p>
  
  <p><strong>My php code</strong></p>
  
  <pre><code>&lt;?php  
  
    $font = 'font-type.ttf';
  
    $rImg = ImageCreateFromJPEG( "test.jpg" );
  
    $color = imagecolorallocate($rImg, 255, 255, 255);
  
    //create bounding box
    $bbox = imagettfbbox ( 38 , 0 , $font , urldecode($_GET['promo']) );
  
    //setting the cordinates
    $x = $bbox[0] + (imagesx($rImg) / 2) - ($bbox[4] / 2) + 200;
    $y = $bbox[1] + (imagesy($rImg) / 2) - ($bbox[5] / 2) + 25;
  
    //write it
    imagettftext($rImg, 38, 0, $x, $y, $color, $font, urldecode($_GET['promo']));
  
    header('Content-type: image/jpeg');
    imagejpeg($rImg, NULL,100);
  
    imagedestroy($rImg);
  
  ?&gt;
  </code></pre>
