<div class="jb51code">下面通过一段代码给大家详解介绍下PHP技术实现加载字体并保存成图片。
<pre class="brush:PHP;">

// Set the content-type
header("Content-type: image/png");

// Create the image
$im = imagecreatetruecolor(400,100);

// Create some colors
$white = imagecolorallocate($im,255,255);
$grey = imagecolorallocate($im,128,128);
$black = imagecolorallocate($im,0);
imagefilledrectangle($im,399,100,$white);

// The text to draw
$text = '字典网';
// Replace path by your own font path
$font = 'fontName.ttf';

// Add some shadow to the text
//imagettftext($im,60,11,21,$grey,$font,$text);

// Add the text
imagettftext($im,70,$black,$text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
