Read text block from capture screen shoot by Tesseract C# window form

Question

Im try read text from bitmap(capture screen) by Tesseract using C#, but result wrong word language. My code:

    Class TesseractApi{
    
            public static auto_login.text_rect get_all_text(Bitmap bitmp = null)
            {
                Bitmap bmp;
    
                if (bitmp != null)
                    bmp = bitmp;
                else bmp = ScreenShot.Capture();
    
                auto_login.text_rect results = new auto_login.text_rect();
                Tesseract.PageIteratorLevel myLevel = PageIteratorLevel.TextLine;
    
                using (var img = PixConverter.ToPix(bmp))
                {
                    using (var page = engine.Process(img))
                    {
                        using (var iter = page.GetIterator())
                        {
                            iter.Begin();
                            do
                            {
                                if (iter.TryGetBoundingBox(myLevel, out var rect))
                                {
                                    var curText = iter.GetText(myLevel).ToLower();
    
                                    results.Add(new auto_login.text_rect()
                                    {
                                        text = curText,
                                        x = rect.X1,
                                        y = rect.Y1
                                    });
    
                                }
                            } while (iter.Next(myLevel));
    
                            //iter.Dispose();
                            //page.Dispose();
                            img.Dispose();
                            bmp.Dispose();
                        }
                    }
                }
                return results;
            }
}

Calling...

Bitmap bmp = new Bitmap("test/screen.png");
text_rect text_arg = TesseractApi.get_all_text(bmp); 

pic capture from screen
