如何从WinAppDriver GetScreenshot方法中使用Tesseract LoadTiffFromMemory加载图像？

using OpenQA.Selenium.Appium;
using OpenQA.Selenium.Appium.Windows;
using Tesseract;

// 创建WinAppDriver实例
AppiumOptions appOptions = new AppiumOptions();
appOptions.AddAdditionalCapability("app", "应用程序的包名或路径");
WindowsDriver<WindowsElement> driver = new WindowsDriver<WindowsElement>(new Uri("http://127.0.0.1:4723"), appOptions);

// 获取应用程序的屏幕截图
var screenshot = driver.GetScreenshot();

// 将屏幕截图保存为Tiff格式的图像文件
string screenshotPath = "屏幕截图路径";
screenshot.SaveAsFile(screenshotPath, ScreenshotImageFormat.Tiff);

// 加载Tiff图像文件到内存中
using (var engine = new TesseractEngine(@"Tesseract引擎路径", "eng", EngineMode.Default))
{
    using (var img = Pix.LoadTiffFromMemory(File.ReadAllBytes(screenshotPath)))
    {
        using (var page = engine.Process(img))
        {
            string recognizedText = page.GetText();
            // 对识别结果进行处理和分析
            // ...
        }
    }
}

// 关闭WinAppDriver实例
driver.Quit();
