  1. Hello, I am trying to get a text replacement script working and I have run into a problem. I want the text replaced by a truetype font that is in a file with other styles of the font, I wanted to know if there is a way to specify a style or name for php to grab the right font style. It works with the font file but it seems to default to the bold italic version. Any help would be great. Here is the code : [code] <?php /*     Dynamic Heading Generator     By Stewart Rosenberger     http://www.stewartspeak.com/headings/        This script generates PNG images of text, written in     the font/size that you specify. These PNG images are passed     back to the browser. Optionally, they can be cached for later use.     If a cached image is found, a new image will not be generated,     and the existing copy will be sent to the browser.     Additional documentation on PHP's image handling capabilities can     be found at http://www.php.net/image/    */ $font_file  = 'Geeza Pro.ttf' ; $font_size  = 50 ; $font_color = '#000000' ; $background_color = '#ffffff' ; $transparent_background  = false ; $cache_images = false ; $cache_folder = 'cache' ; /*   ---------------------------------------------------------------------------   For basic usage, you should not need to edit anything below this comment.   If you need to further customize this script's abilities, make sure you   are familiar with PHP and its image handling capabilities.   --------------------------------------------------------------------------- */ $mime_type = 'image/png' ; $extension = '.png' ; $send_buffer_size = 4096 ; // check for GD support if(!function_exists('ImageCreate'))     fatal_error('Error: Server does not support PHP image generation') ; // clean up text if(empty($_GET['text']))     fatal_error('Error: No text specified.') ;     $text = $_GET['text'] ; if(get_magic_quotes_gpc())     $text = stripslashes($text) ; $text = javascript_to_html($text) ; // look for cached copy, send if it exists $hash = md5(basename($font_file) . $font_size . $font_color .             $background_color . $transparent_background . $text) ; $cache_filename = $cache_folder .
