c# 使用charlesw tesseract生成hocr文件

Question

如何使用 tesseract 包装器 here 生成 hocr

目前我需要将 tessdata 的位置动态添加到环境变量中并运行我的代码

System.Diagnostics.Process pProcess = new System.Diagnostics.Process();
            pProcess.StartInfo.FileName = System.IO.Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]) + @"\tesseract-3.05.00dev-win32-vc19\tesseract.exe";
                            string inputImg = @"00067.jpg";
            string  hocrLocation = @"00067";
            string argsPdf = "\"" + inputImg + "\"" + " " + "\"" + hocrLocation + "\"" + " hocr ";
            Console.WriteLine(argsPdf);
            pProcess.StartInfo.Arguments = argsPdf;
            pProcess.StartInfo.CreateNoWindow = false;
            pProcess.StartInfo.UseShellExecute = false;
            pProcess.StartInfo.RedirectStandardOutput = true;
            pProcess.Start();
            string strOutput = pProcess.StandardOutput.ReadToEnd();
            Console.WriteLine("OUtput: " + strOutput);
            pProcess.WaitForExit();

然后我找到了 tesseract 包装器。如何使用包装器生成 hocr 文件？我找不到如何做的例子。

这是我正在使用的当前代码（来自示例），但如何输出 hocr 文件？

var testImagePath = "./phototest.tif";
            if (args.Length > 0)
            {
                testImagePath = args[0];
            }

            try
            {
                using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
                {
                    using (var img = Pix.LoadFromFile(testImagePath))
                    {
                        using (var page = engine.Process(img))
                        {

                        }
                    }
                }
            }
            catch (Exception e)
            {
                Trace.TraceError(e.ToString());
                Console.WriteLine("Unexpected Error: " + e.Message);
                Console.WriteLine("Details: ");
                Console.WriteLine(e.ToString());
            }

string hocrText = page.GetHOCRText(pageNum - 1);
