imagecolorallocate imagestring

Hello,

I like to make the background transparent and the font color white.
some help is needed please:


$image = imagecreate(60, 17);
$white = imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image,   0,   0,   0);
imagestring ($image, 3, 0, 4, $t_num, $black);
imagepng    ($image);
imagedestroy($image);

yes but in all lower case and $black instead of $back (http://us2.php.net/manual/en/function.imagecolortransparent.php)

and when you do that anything which was black will be transparent...

transparency makes that color a signal in the image rather than setting the color to transparent for future painting.
