php libpng错误 [英] php libpng error

问题描述

我正在运行测试机设置，以用作开发目的的本地主机.我已经从零开始进行了MySQL，Apache2，带有GD(libjpeg，libpng和php的freetype和xpm的php)的PHP5以及Zend Framework的构建.这是MacBook Pro.

除了libpng之外，其他所有东西都运行良好.运行在另一台计算机上运行的验证码脚本时出现以下错误:

I''m running a test machine setup to be used as localhost for development purposes. I''ve done a build from scratch of MySQL, Apache2, PHP5 with GD (libjpeg, libpng, and php''s freetype and xpm), and Zend Framework. This is a MacBook Pro.

Everything is working great with exception of libpng. I''m getting the following error when running a captcha script that works on another machine:

PHP Warning: imagecreatefrompng(): gd-png error: cannot allocate libpng main struct in/Library/WebServer/Documents/.../kcaptcha.php on line 164

php文件中的行是:

The line in the php file is:

$font=imagecreatefrompng($font_file);

我得到的只是蓝色背景，而不是上面带有文字的蓝色背景图像.

我已经将整个站点目录设置为777，所以我认为这不是权限问题，除非有一个临时目录设置不正确.

有什么建议吗?

谢谢

Instead of the blue background image with text on it, all I get is the blue background.

I''ve set the entire site directory to 777, so I don''t think it''s a permission problem, unless there is a temp directory that'';s not set right.

Any advise?

Thanks

font = imagecreatefrompng(

font=imagecreatefrompng(

font_file);

font_file);
