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
