php技术实现加载字体并保存成图片

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。

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

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

    // Create some colors 
    $white = imagecolorallocate($im, 255, 255, 255); 
    $grey = imagecolorallocate($im, 128, 128, 128); 
    $black = imagecolorallocate($im, 0, 0, 0); 
    imagefilledrectangle($im, 0, 0, 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, 0, 11, 21, $grey, $font, $text); 

    // Add the text 
    imagettftext($im, 60, 0, 0, 70, $black, $font, $text); 

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

如果想保存图可以用下面代码

    ob_start();  
      imagejpeg($im); 
    $img = ob_get_contents();  
    ob_end_clean();  
    $size = strlen($img);  

    $fp2=@fopen('tst.jpg', "a");  
    fwrite($fp2,$img);  
    fclose($fp2);  

以上代码就可以完成加载字体并保存成图片，希望大家会喜欢
