$image = imagecreatefrompng('images/transparentimage.png');
$width  = imagesx($image);
$height = imagesy($image);
$imageOut     = imagecreatetruecolor($width, $height);
$background = imagecolorallocatealpha($imageOut, 0, 0, 0, 0);
imagefill($imageOut, 0, 0 , $background);
imagecopyresampled($imageOut, $image, 0, 0, 0, 0, $width, $height,  $width, $height);
imagesavealpha($imageOut, true);
imagecolortransparent($imageOut, $background);

Modify the next line

imagettftext ($imageOut , $font['size'] , $font['angle'] , $font['x-offset'] , $font['y-offset'] , $font['color'] , $font['file'], $text );

$font['color'] has to be imagecolorallocatealpha($imageOut, 51, 102, 255, 0) (any color) and should NOT be black like the $background imagecolorallocatealpha($imageOut, 0, 0, 0, 0). Black will become transparent.

Modify the next line

imagegif($imageOut);

Or you can maybe play with the

$transparent_colour_red = 0;
$transparent_colour_green = 0;
$transparent_colour_blue = 0;
