We have some working example using PHP at:
http://www.thebook-demo.com/php/
It is CRUCIAL that you don't output any blank lines
before the "Content-type" - that often causes problems..
The source is:
<?
Header("Content-type: image/png");
// note - must use the absolute font path
// be careful about blank lines in your code which will output a blank and confuse browser
$text = "This is a PHP Button";
$font = "/pub/comwww/thebook-demo/php/gd/fonts/arial.ttf";
if(!isset($s)) $s=11;
$size = imagettfbbox($s,0,$font,$text);
$dx = abs($size[2]-$size[0]);
$dy = abs($size[5]-$size[3]);
$xpad=19;
$ypad=19;
$im = imagecreate($dx+$xpad,$dy+$ypad);
$blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF);
$black = ImageColorAllocate($im, 0,0,0);
$white = ImageColorAllocate($im, 255,255,255);
ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black);
ImageRectangle($im,0,0,$dx+$xpad,$dy+$ypad,$white);
ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black, "$font", $text);
ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white, "$font", $text);
Imagepng($im);
ImageDestroy($im);
?>
