I am using the following code:

api.SetImage(OcrPix.FromFile(testBitmap));
api.Recognize();
plainText = api.GetUtf8Text();


OcrBoxa ocrBoxa = null;
OcrPixa ocrPixa = null;

api.GetWords(out ocrBoxa, out ocrPixa);
ResultWords = new List<string>();
for (int i = 0; i < ocrPixa.Pixes.Length; i++)
{
string word = ocrPixa.Pixes[i].Text;
if (api.IsValidWord(word.Trim()))
ResultWords.Add(word);
}


The property ocrPixa.Pixes[i].Text is always null. The plain text displays as many words.
Please advise on getting the words list for a given language from OCRApi.
I am trying to avoid parsing the words from text as rules of parsing are different in different languages.

Hello,

The GetWords method returns Pixa in Leptonica style. The Text property of the Leptonics image returns the comment contained in the image's caption. It has nothing to do with the recognizable text.

Please use the following code instead
Code:
var iter = api.Iterator;
api.SetImage(pix);
api.Recognize();

do
{
    var text = iter.GetUtf8Text(PageIteratorLevel.RIL_WORD);
    var bbox= iter.PageIterator.GetBoundingBox(PageIteratorLevel.RIL_WORD);
} while (iter.Next(PageIteratorLevel.RIL_WORD));
