从 .Net 调用 Image Magick 命令答案

【问题标题】：Calling Image Magick commands from .Net从 .Net 调用 Image Magick 命令

【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。没关系，但是当我通过 C# 应用程序调用它时，最后出现错误。当我通过我的应用程序调用它时，我不知道它为什么会期望 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();`

"convert.exe: 选项 Affine 的参数无效：'需要至少 1 个 CP'@error/distort.c/GenerateCoefficients/530。\r\nconvert.exe: 无法打开图像2,2': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format2,2' @error/constitute.c/ReadImage/550.\r\nconvert.exe: 无法打开图像 0,0': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format0,0' @error/constitute.c/ReadImage/550.\r\nconvert.exe: 无法打开图像2,198': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format2,198'@error/constitute.c/ReadImage/550。\r\nconvert.exe: 无法打开图像0,200': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format0,200'@error/constitute.c/ReadImage/550。\r\nconvert.exe : 无法打开图像 198,198': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format198,198' @error/constitute.c/ReadImage/550。\r\nconvert.exe: 无法打开图像 200,200': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format200,200' @error/constitute.c/ReadImage/550。\r \nconvert.exe: 无法打开图像198,2': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format198,2'@error/构成.c/ReadImage/550。\r\nconvert.exe: 无法打开图像200,0'': No such file or directory @ error/blob.c/OpenBlob/2641.\r\nconvert.exe: no decode delegate for this image format200,0''@错误/构成.c/ReadImage/550.\r\n"

【解决方案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。还要去掉第一个引号后的多余前导空格：

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