Font generator - php

[Protege]

Made this up, thought i'd release it to you guis. Probably loads on teh internets.

<?php
class fontGenerator
{
    private $face;
    private $size;
    private $width;
    private $height;
    private $text = array();
    
    function __construct( $face, $size, $lSpacer = 0 )
    {
        header( 'Content-Type: image/png' );
        
        $this->face = $face;
        $this->size = $size;
        $this->width = $lSpacer;
        
        return true;
    }
    
    public function addText( $str, $colour )
    {
        $this->text[] = array( $str, $colour, $this->width );
        $arr = imagettfbbox( $this->size, 0, $this->face, $str );
        $this->width = abs( $this->width + $arr[ 4 ] );
        $this->height = abs( $arr[ 5 ] - $arr[ 1 ] );
        
        return true;
    }

    public function generateText()
    {    
        $holder = imagecreatetruecolor( $this->width, $this->height );
        imagesavealpha( $holder, true );
        imagefill( $holder, 0, 0, imagecolorallocatealpha( $holder, 0, 0, 0, 127 ) );
        
        foreach( $this->text as $text )
        {
            $e_colour = explode( ',', $text[ 1 ] );
            $colour = imagecolorallocate( $holder, $e_colour[ 0 ], $e_colour[ 1 ], $e_colour[ 2 ] );
            imagettftext( $holder, $this->size, 0, $text[ 2 ], $this->size - ( $this->size / 20 ), $colour, $this->face, $text[ 0 ] );
        }
        
        imagepng( $holder );
        imagedestroy( $holder );

    }
}

usage:

require 'fontgenerator.class.php';

$fontGenerator = new fontGenerator( 'ARIALNI.TTF', 24 );
/* fontGenerator( string font, int size, int leftspacer (optional) ); */
$fontGenerator->addText( 'welcome ', '147,215,255' );
/* addText( string text, string colour(RGB) ); */
$fontGenerator->addText( 'james', '99,99,99' );
$fontGenerator->generateText();

Not being a pain, but a working demo would be nice.
