imagettftext不工作 [英] imagettftext not working

问题描述

我试图在图像中写文本仅用于测试，因为我的Zabbix安装不是在图形中写入文本。我从php.net网站复制了下面的代码（ http://php.net /manual/en/function.imagettftext.php ）

I've tried to write text in an image just for testing purposes because my Zabbix install is not writing text in the graphs. I've copied the code bellow from the php.net website (http://php.net/manual/en/function.imagettftext.php)

<?php
// Set the content-type
header('Content-Type: image/png');

// Create the image
$im = imagecreatetruecolor(400, 30);

// 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, 29, $white);

// The text to draw
$text = 'Testing...';
// Replace path by your own font path
$font = '/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf'; 

// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

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

有没有人有想法？

推荐答案

我已经弄清楚这里有什么问题。权限访问truetype文件。 PHP无法访问该文件，因此无法写入。

I've figure out what was the problem here. Permissions to access the truetype file. PHP could not access the file so it couldn't write.

我没有看到问题，因为我没有运行E_ALL。现在一切顺利运行

I was not seeing the problem because I was not running with E_ALL. Now everything is running smoothly
