从.Net调用Image Magick命令 [英] Calling Image Magick commands from .Net

问题描述

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调用它时，这很奇怪.可以，但是当我通过C#应用程序调用它时，最后出现错误.我不知道当我通过我的应用程序调用它时，为什么会期望Affine参数.请帮忙.

I am trying call a Image Magick inside a .NET app. It is very strange that when I copy the same arguments and use command line to call it. It is OK but when I call it by my C# app, I get the error at the end. I don't know how come it expects a Affine argument when I call it by my app. Please help.

  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();`

推荐答案

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精度引号.在第一个引号之后也要立即删除多余的空格:

Change the single quotes around ' 2,2 0,0 2,198 0,200 198,198 200,200 198,2 200,0' to escaped double quotes. Also get rid of the extra leading space immediately after the first quote:

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