Question

我在命令提示符下运行pdftoppm，但无法创建任何输出。

这是我的输入

c:\test>pdftoppm -r 600 png W10475.pdf test

这是我在关联的'test'目录中的文件

c:\test>dir
 Volume in drive C is OS
 Volume Serial Number is 32C5-D3A1

 Directory of c:\test

这是我的命令

的输出

  --help            : print usage information
  -?                : print usage information

没有抛出任何错误消息，也没有文件写入c：\ test文件夹。我以为pdftoppm.exe会写入调用它的同一个文件夹。我错了，还是没有写出输出？如果是这种情况，我该如何让它生成一些输出。

Answer 1

命令必须为：pdftoppm -r 600 -png W10475.pdf test
