这篇文章主要介绍了php技术实现加载字体并保存成图片,需要的朋友可以参考下

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);
