Changing font for GD image text

[handle]

I have made this to display a txt file in a php generated image.

<?php 
// shout sig 
header("Content-type: image/png"); 
$file = array_reverse(file('shouts.txt'));


$im = @imagecreate(550, 120) 
   or die("Error! Could not create image stream.s"); 
$background_color = imagecolorallocate($im, 0, 0, 0); 
$text_color = imagecolorallocate($im, 0, 255, 0); 
$i = 1; 
$j = 0; 
foreach ($file as $line_num => $line) { 
    if($i <= count($file)-1) 
        imagestring($im, 2, 5, $j,  substr($line, 0, strlen($line)-1), $text_color); 
    else 
        imagestring($im, 2, 5, $j,  $line, $text_color); 
    $j+=15; 
    $i++; 
} 
imagepng($im); 
imagedestroy($im); 
?> 

How can i change the font style of the text displayed?

I have a font as.ttf in the same dirrectory as this script.

I changed my code to.

<?php 
// shout sig 
header("Content-type: image/png"); 
putenv('GDFONTPATH=' . realpath('.'));  // added this


$file = array_reverse(file('shouts.txt'));


$im = @imagecreate(550, 120) 
   or die("Error! Could not create image stream.s"); 
$background_color = imagecolorallocate($im, 0, 0, 0); 
$text_color = imagecolorallocate($im, 0, 255, 0); 
$font = 'as';  // added this



$i = 1; 
$j = 0; 
foreach ($file as $line_num => $line) { 
    if($i <= count($file)-1) 
        imagestring($im, 2, 5, $j, substr($line, 0, strlen($line)-1), $text_color, $font); // added $font
    else 
        imagestring($im, 2, 5, $j, $line, $text_color, $font); // added $font
    $j+=15; 
    $i++; 
} 
imagepng($im); 
imagedestroy($im); 
?> 

But i get the error
Wrong parameter count for imagestring() on line 22

Check out the function I told ya. Scroll down the page a bit more. You don't want imagestring.
