imagettftext无法打开字体文件 [英] imagettftext cannot open font file

问题描述

使用来自php.net的示例，我得到了警告，并且图像显示不正确.我提供.ttf文件的完整路径，如下所示:/var/www/public/myfont.ttf

Using the example from php.net I get a warning, and the image is not rendered correctly. I supply a full path to the .ttf file like so: /var/www/public/myfont.ttf

PHP Warning:  imagettftext() [<a href='function.imagettftext'>function.imagettftext</a>]: Could not find/open font in <phpfile>

我正在使用在此处找到的自定义.ttf字体.我可以在Ubuntu中很好地将文件打开为有效的字体文件.我还尝试了其他字体，结果相同.

I am using a custom .ttf font found here. I can open the file fine in Ubuntu as a valid font file. I also attempted other fonts, with the same result.

我正在使用32位Ubuntu 10.04 LTS，并安装了apache2，php5，freetype6和php5-gd.我还尝试使用ttf文件将chmod 777文件和文件夹更改为相同的结果.

I am using Ubuntu 10.04 LTS 32 bit, with apache2, php5, freetype6 and php5-gd installed. I also attempted to chmod 777 file and folder with ttf file, with the same result.

如何使用自定义ttf字体文件来使示例工作?

How can I get the example working using a custom ttf font file?

*我正在使用的代码:

* The code I'm using:

<?php
// File is: /var/www/public/test.php
// Apart from $font variable, it's copy-pasted from php.net

// 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 = '/var/www/public/UnmaskedBB.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);
?>

phpinfo()的输出；
