PHP - imagettftext not working and GD installed
提问by Steve Peretz
It's being long hours that I'm still looking for answer to this problem.. All the solutions I find are around catching the font name but I am pretty sure this isn't my problem.
我仍在寻找这个问题的答案已经很长时间了..我找到的所有解决方案都围绕着字体名称，但我很确定这不是我的问题。
It looks like GD is installed
好像安装了GD
array(11) {
["GD Version"]=>
string(27) "bundled (**2.0.34 compatible**)"
["FreeType Support"]=>
bool(false)
["T1Lib Support"]=>
bool(false)
["GIF Read Support"]=>
bool(true)
["GIF Create Support"]=>
bool(true)
["JPEG Support"]=>
bool(true)
["PNG Support"]=>
bool(true)
["WBMP Support"]=>
bool(true)
["XPM Support"]=>
bool(true)
["XBM Support"]=>
bool(true)
["JIS-mapped Japanese Font Support"]=>
bool(false)
}
Above you can see my GD support. My PHP version is 5.3 and I'm running on Linux.
在上面你可以看到我的 GD 支持。我的 PHP 版本是 5.3，我在 Linux 上运行。
I have tried few different code examples from different websites and none works. ImageString does work for me but I need to get imagettftextto work..
我从不同的网站尝试了几个不同的代码示例，但没有一个有效。ImageString 对我有用，但我需要让imagettftext工作..
This is the last code I have tried now-
这是我现在尝试的最后一个代码-
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
// Set the content-type
header('Content-Type: image/png');
// Create the image
$im = imagecreatetruecolor(400, 100) or die("Can't create image!");
// 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
$font = 'arial.ttf';
// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, 'arial.ttf', $text);
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, 'arial.ttf', $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

Had the same problem, with FreeType installed, solution was
有同样的问题，安装了 FreeType，解决方案是
$font = "./Arial.ttf"; // <--- put ./ in front of filename

Notice you don't have Free Type installed:
请注意，您没有安装 Free Type：
["FreeType Support"]=>
bool(false)
This function requires both the GD library and the ? FreeType library.
此函数需要 GD 库和 ? FreeType 库。
You will need to install Free Type library before you can use this function.
您需要先安装 Free Type 库才能使用此功能。
try installing these package:s freetype, freetype-devel
尝试安装这些包：s freetype，freetype-devel
If you compiled PHP you can make sure you added enabled freetype during compile time:
如果你编译了 PHP，你可以确保在编译时添加了启用的 freetype：
--with-freetype-dir=/usr/include/freetype2/ --with-freetype
Or if you using something such as YUM or APT-GET it should be really simple to install those libraries, and a quick search ob google with get you started.
或者，如果您使用诸如 YUM 或 APT-GET 之类的东西，那么安装这些库应该非常简单，并且可以快速搜索 ob google 以帮助您入门。

Well i also got problem around
嗯，我也有问题
$font='arial.tff';
I think you should provide absolute path to the $fontlike
我认为您应该提供$font 的绝对路径，例如
$font="c:/windows/fonts/arial.ttf";
i assume you are a windows user. and remove
我假设您是 Windows 用户。并删除
header('Content-Type:image/png');
to get the real error

Andrew is right, the php manual for imagettftextstates FreeType is required to use imagettftext, imagettfbox, and others. Most people the GD devel package will install FreeType automatically:
安德鲁是正确的，对于imagettftext PHP手册的FreeType需要使用状态imagettftext，imagettfbox和其他人。大多数人 GD 开发包会自动安装 FreeType：
Fedora/Redhat:
Fedora/红帽：
yum install gd gd-devel php-gd
Debian/Ubuntu:
Debian/Ubuntu：
apt-get install php5-gd libgd2-xpm libgd2-xpm-dev
This error was probably in your logs:
此错误可能在您的日志中：
PHP Fatal error: Call to undefined function imageTTFText()
