具体是什么错？

我不懂PHP﹐不過想接分
\---------------------------------------------------------------
好东东，先试一试看看。
\---------------------------------------------------------------
PHP是个有意思的东西，希望她一路走好
\---------------------------------------------------------------
我的居然提示：
PHP Fatal error: Call to undefined function: imagecreate() in E:\jysweb\office\test\class.php on line 89
要配置......
\---------------------------------------------------------------
这么长的代码，找错真是难啊：）恭喜楼主
\---------------------------------------------------------------
php.ini
extension=php_gd.dll
\---------------------------------------------------------------
这段代码我测试过了，本身没有什么错误！
图像是一个立体饼状图，切成了3块，还有一个十字架，左下角还有一个小桶
p.s.我的gd不支持gif,所以我用了png图
\---------------------------------------------------------------
不过这个类确实写得很精致，堪称经典代码！

楼主很热心，恭喜~
\---------------------------------------------------------------
可能是里面的计算，精度不够。
直接整除了

Congratulation!
I want to try,but i can't understand the above-mentioned code.
\---------------------------------------------------------------
太长了，头晕。
\---------------------------------------------------------------
呵呵
\---------------------------------------------------------------
不会。
\---------------------------------------------------------------
碰到高人了，快帮我，
用gd画好的图用
