Question

我正在尝试在.NET应用程序中调用Image Magick。当我复制相同的参数并使用命令行来调用它时，这是非常奇怪的。没关系，但是当我通过我的C＃应用程序调用它时，我最后得到了错误。当我通过我的应用程序调用它时，我不知道它是怎么期望一个Affine参数。请帮忙。

  var proc = new Process
   {
      StartInfo = new ProcessStartInfo
     {
    FileName = @"C:\Program Files (x86)\ImageMagick-6.8.4-Q16\convert.exe",
    Arguments = "\"C:\\Users\\Pouya\\Desktop\\Rugs\\test.jpg\" -matte -virtual-pixel transparent -distort Perspective ' 2,2 0,0 2,198 0,200 198,198 200,200 198,2 200,0' \"C:\\Users\\Pouya\\Desktop\\Rugs\\testResult.jpg\"",
    UseShellExecute = false,
    RedirectStandardError = true,
    CreateNoWindow = true
     }
   };

 proc.Start();`

Answer 1

将' 2,2 0,0 2,198 0,200 198,198 200,200 198,2 200,0'周围的单引号更改为转义双引号。在第一次引用后立即摆脱额外的领先空间：

\"2,2 0,0 2,198 0,200 198,198 200,200 198,2 200,0\"
