I am iterating over recognize api as suggested here. "Result iterator example" https://github.com/tesseract-ocr/tesseract/wiki/APIExample Pix *image = pixRead("/usr/src/tesseract/testing/phototest.tif"); tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI(); api->Init(NULL, "eng"); api->SetImage(image); api->Recognize(0); tesseract::ResultIterator* ri = api->GetIterator(); tesseract::PageIteratorLevel level = tesseract::RIL_WORD; if (ri != 0) { do { const char* word = ri->GetUTF8Text(level); float conf = ri->Confidence(level); int x1, y1, x2, y2; ri->BoundingBox(level, &x1, &y1, &x2, &y2); printf("word: '%s'; \tconf: %.2f; BoundingBox: %d,%d,%d,%d;\n", word, conf, x1, y1, x2, y2); delete[] word; } while (ri->Next(level)); } it seems we do before calling next. If I am calling next first, it will skip over the first detections. Unfortunately when I get this error, **'NoneType' object is not iterable issue** When there is no detection. Here is the code in python-tesserocr if (iterator != None): next = True while (next): x,y,right,bottom = iterator.BoundingBox(level) next = iterator.Next(level) it throws an error on iterator.BoundingBox saying that the iterator is empty. If I call "next = iterator.Next(level)" first, it avoids that error, but it also skip over the first detection Here is the image, just the whitespace image  Is there any API to check the hasNext()?
