php技术实现加载字体并保存成图片

PHP实战
// 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);
