使用ImageMagick将wmf转成jpg图片

命令如下：

D:\source\WordClient\Lib\ImageMagick\convert.exe convert "C:\Users\Administrator\AppData\Local\Temp\17906a70-0844-4aaa-8ef8-55629b5430f7\word\media/image2.wmf" "d:\users\administrator\documents\aa结构化工具\media/我国六省水痘—带状疱疹病毒糖蛋白基因特征分析+ (1)_image2_wmf.jpg"

未转成功，报错如下：

搜索了一下，说没有安装Ghostscript

安装之后，转换成功
