从C#代码中执行Potrace命令，将位图图像转换为XAML

Question

我正在尝试将我的位图图像转换为XAML格式。目前，我在命令提示符下使用Potrace。我将只通过命令提示符传递输入文件。我的问题是，我必须使用C#代码来做同样的事情。我必须在外部调用Potrace进程并执行它。我尝试了以下代码

               Process potrace = new Process
           {
               StartInfo = new ProcessStartInfo
               {
                   FileName = "potrace.exe",
                   Arguments = "-s -u 1", //SVG
                   RedirectStandardInput = true,
                   RedirectStandardOutput = true,
                   RedirectStandardError = Program.IsDebug,
                   UseShellExecute = false,
                   CreateNoWindow = true,
                   WindowStyle = ProcessWindowStyle.Hidden
               },
               EnableRaisingEvents = false
           };
           StringBuilder svgBuilder = new StringBuilder();
           potrace.OutputDataReceived += (object sender2, DataReceivedEventArgs e2) =>
           {
               svgBuilder.AppendLine(e2.Data);
           };
           if (Program.IsDebug)
           {
               potrace.ErrorDataReceived += (object sender2, DataReceivedEventArgs e2) =>
               {
                   Console.WriteLine("Error: " + e2.Data);
               };
           }
           potrace.Start();
           potrace.BeginOutputReadLine();
           if (Program.IsDebug)
           {
               potrace.BeginErrorReadLine();
           }

           BinaryWriter writer = new BinaryWriter(potrace.StandardInput.BaseStream);

           Bitmap.Save(writer.BaseStream, ImageFormat.Bmp);
           potrace.StandardInput.WriteLine();
           potrace.WaitForExit();

这段代码给了我一个错误，编译器说Program不存在于此内容中。帮我解决这个问题。如果你有任何其他建议，我很乐意接受。

只需使用Potrace的C#版本即可，参见here。

C#版的http://potrace.sourceforge.net/ (彼得·塞林格)基于http://www.drawing3d.de/完成了艰难的工作。

尝尝这个!某些不起作用的代码部分会被注释禁用。此版本从属性"Arguments“获取源bmp图像。

        Process potrace = new Process
        {
            StartInfo = new ProcessStartInfo
            {
                FileName = @"C:\potrace-1.11.win64\potrace.exe",
                Arguments = "C:\\potrace-1.11.win64\\circle.bmp --backend dxf", //DXF
                RedirectStandardInput = true,
                RedirectStandardOutput = true,
           //     RedirectStandardError = Program.IsDebug,
                UseShellExecute = false,
                CreateNoWindow = true,
                WindowStyle = ProcessWindowStyle.Hidden
            },
            EnableRaisingEvents = false
        };

        StringBuilder svgBuilder = new StringBuilder();
        potrace.OutputDataReceived += (object sender2, DataReceivedEventArgs e2) =>
        {
            svgBuilder.AppendLine(e2.Data);
        };
        /*
        if (Program.IsDebug)
        {
            potrace.ErrorDataReceived += (object sender2, DataReceivedEventArgs e2) =>
            {
                Console.WriteLine("Error: " + e2.Data);
            };
        }
         */

        potrace.Start();
         /*
          * 
        potrace.BeginOutputReadLine();
        if (Program.IsDebug)
        {
            potrace.BeginErrorReadLine();
        }
        */
        /*
        BinaryWriter writer = new BinaryWriter(potrace.StandardInput.BaseStream);
        // Construct a new image from the GIF file.
        Bitmap bmp2 = new Bitmap(@"C:\Users\Matus\Desktop\potrace-1.11.win64\kruz.bmp");
        bmp2.Save(writer.BaseStream, System.Drawing.Imaging.ImageFormat.Bmp);
        potrace.StandardInput.WriteLine(); //Without this line the input to Potrace won't go through.
         * **/
        potrace.WaitForExit();
