OpenCVSharp4 Rect转IronOCR CropRectangle异常，OCR识别区域不符

开发项目时，使用IronOCR读取OpenCVSharp4定义的区域，遇到如下问题：IronOCR的CropRectangle方法依赖System.Drawing.Rectangle，将OpenCvSharp.Rect转换后调用Input.Add(Image, ContentArea)，识别结果不符合预期。推测是转换后的裁剪区域异常导致部分文字被截断，扩大裁剪区域的宽高后识别恢复正常。

相关代码如下：

var Ocr = new IronTesseract();
String[] splitText;
using (var Input = new OcrInput())
{
    //OpenCv
    OpenCvSharp.Rect rect = new OpenCvSharp.Rect(55, 107, 219, 264);

    //IronOCR
    Rectangle ContentArea =  new Rectangle() { X = rect.TopLeft.X, Y = rect.TopLeft.Y, Height = rect.Height, Width = rect.Width };
    CropRectangle r = new CropRectangle(ContentArea);
    CordBox.Text = r.Rectangle.ToString();

    //OpenCv
    resizedMat.Rectangle(rect.TopLeft, rect.BottomRight, Scalar.Blue, 3);
    resizedMat.Rectangle(new OpenCvSharp.Point(55, 107), new OpenCvSharp.Point(219, 264), Scalar.Brown, 3);
    Cv2.ImShow("resizedMat", resizedMat);

    //IronOCR
    Input.Add(@"C:\Projects\AnExperiment\WpfApp1\Images\TestSave.PNG", r);
    Input.EnhanceResolution();
    var Result = Ocr.Read(Input);
    ResultBox.Text = Result.Text;
    splitText = ResultBox.Text.Split('\n');
}
