关于gd库和jpgraph的一个莫名其妙的问题，各位帮忙看看
php.5.3.6, php-gd支持编译为为DSO形式，gd库用的2.0.34 compatible
我有一个php程序，用到了jpgraph，一台debian，一台ubuntu11，两台机器的gd库和php和gd扩展都是手动编译安装上的，其他的比如libpng，libjpeg，libfreetype，都装的是同一个版本的
但是，该程序在debian上运行的就没问题，在ubuntu11上在执行stroke方法生成文件的时候就会输出乱码到浏览器，apache的error_log里没有任何错误信息
phpinfo里面的gd部分完全一模一样（ubuntu11用从源上下载下来的新版本一些的包也是一样的效果）
------解决方案--------------------
把stroke输出到文件中保存为图片文件。试试
如果浏览器不同，有可能是浏览器的问题。php header的问题。
------解决方案--------------------
字体文件是需要自己安装的
不知道将 window 中的拷贝过去是否能用，你可以试一下
