Help with Random Image...

Hi guys, I'm having trouble with the following code.
Everything works fine if I use only the Imagestring
function but not with the Imagettftext function.

Are there any special requirements to use the
Imagettftext function?

Hope you can help.
LCP

PHP Code:


		
			
<?php



//random_number.php

$img_number = imagecreate(100,50);

$white = imagecolorallocate($img_number,255,255,255);

$black = imagecolorallocate($img_number,0,0,0);

$grey_shade = imagecolorallocate($img_number,204,204,204);



imagefill($img_number,0,0,$grey_shade);

ImageRectangle($img_number,5,5,94,44,$black);

ImageRectangle($img_number,0,0,99,49,$black);



$number = get_random();



//Imagestring($img_number,9,30,15,$number,$black);

Imagettftext($img_number, 30,0,10,33,$black,'trebuchet.ttf',$number);



header("Content-type: image/jpeg");

imagejpeg($img_number);



function get_random()

{

srand(time());

$max = getrandmax();

return rand(1,$max) + rand(1,$max);

} 



?>

Make sure your font file is the in the same directory as your script, or if it isn't, ensure the path in imagettftext() is pointing to the correct location.

The font file is there but I get the following error:

Fatal error: Call to undefined function: imagettftext() in /home/user/public_html/random_number.php on line 16

Thanks.

PHP Code:


		
			
 Fatal error: Call to undefined function: imagettftext()

98% of the time that error string means the function is not loaded or the library itself is not loaded. The other 2% of the time the function has been disabled by the host.

Lets first make sure you have the library (GD) installed. Run this sniplet ->

PHP Code:


		
			
 $loaded = ( bool ) false;

$lib = 'GD';

$data = get_loaded_extensions();

foreach ( $data as $val )

    {

    if ( stristr( $val, $lib ) ) {

        $loaded = true;

    }

    echo $val . '<br /><br />';

}

if ( $loaded ) {

    echo '<strong>' . $lib . ' is loaded';

} else {

    echo '<strong>' . $lib . ' is not loaded loaded';

}

See what that returns. It will show your installed libraries and print weather GD is installed or not.

If GD is installed - I would call your host and ask them why the function was disabled - if thats the case...

does the version of GD that you are running support that function?

My apologies, I didn't read what you said close enough.

Np.

It seems that the problem may be due to the legal issues
with .gif creation on the new versions of PHP.

If so,
