Unfortunately the current GD-2.0.1 has a bug which prevents truetype
fonts from being anti-aliased correctly on truecolor images. This is
fixed in GD-2.0.2 which unfortunatelyt doesn't exist. As of PHP 4.3
we have bundled GD2 with PHP and fixed this and many other bugs.
<?
$im = ImageCreateTruecolor(720,180);
ImageAlphaBlending($im,$blend);
ImageFilledRectangle($im,0,0,719,179,0x00ffffff);
ImageTTFText($im,80,0,10,135,0x00000000,
"Garabd","ABCdef123");
Header('Content-Type: image/png');
ImagePNG($im);
