使用
example from php.net我收到警告,图像无法正确呈现.我提供了.ttf文件的完整路径,如下所示:/var/www/public/myfont.ttf
PHP Warning: imagettftext() [<a href='function.imagettftext'>function.imagettftext</a>]: Could not find/open font in <PHPfile>
我使用的是自定义.ttf字体here.我可以在Ubuntu中将文件打开为有效的字体文件.我也尝试了其他字体,结果相同.
我正在使用Ubuntu 10.04 LTS 32位,安装了apache2,PHP5,freetype6和PHP5-gd.我还尝试使用ttf文件chmod 777文件和文件夹,结果相同.
*编辑:我正在使用的代码:
<?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); $grey = imagecolorallocate($im,128,128); $black = imagecolorallocate($im,0); imagefilledrectangle($im,399,29,$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,20,11,21,$grey,$font,$text); // Add the text imagettftext($im,10,$black,$text); // Using imagepng() results in clearer text compared with imagejpeg() imagepng($im); imagedestroy($im); ?>

测试is_file和is_readable:
$font = realpath('./').'/UnmaskedBB.ttf'; echo "Font: ".$font; // /var/www/public/UnmaskedBB.ttf echo "Is file? ".is_file($font); // 1 echo "Is readable? ".is_readable($font); // 1
您可以尝试插入:
putenv('GDFONTPATH=' . realpath('.'));
在第一个imagettftext前面,只是为了确保它没有路径问题.
UPDATE
如果您使用fc-cache等字体缓存,请不要忘记刷新它,例如:
sudo fc-cache -f -v
