错误一

type init 错误。提示找不到libgdiplus组件

Make solution 1：

ln -s /usr/local/lib/libgdiplus.so /usr/lib64/libgdiplus.so

ln -s /usr/local/lib/libgdiplus.so /usr/libgdiplus.so

Make solution 2：

vi /etc/ld.so.conf

##将 /usr/local/lib 加入

ldconfig #配置生效。

错误二

生成出来的图片没有任何文字 DrawString not dislpay in image
