Is there a way to iterate over the classifier choices in tesseract 4

[Sebastian Correa]

I am working in a project with tesseract 3 and I want to migrate to Tesseract 4. When I iterate I dont get the multiple choices like in tesseract 3.

Tesseract 3:

Symbol: O, Conf: 91.2741
O conf: 91.2741
C conf: 82.6332
G conf: 80.8132
Q conf: 80.6637
D conf: 80.5849

Tesseract 4:

Symbol: O, Conf: 99.5507

O conf: 99.5507

This is my code:

tesseract::PageIteratorLevel level = RIL_SYMBOL;

if(ri != 0) {

do {

const char* symbol = ri->GetUTF8Text(level);

float conf = ri->Confidence(level);

if(symbol != 0) {

cerr << "Symbol: " << symbol << ", Conf: " << conf << endl;

tesseract::ChoiceIterator ci(*ri);

do {

const char* choice = ci.GetUTF8Text();

cerr << choice << " conf: " << ci.Confidence() << endl;

} while(ci.Next());

}

cerr << "---------------------------------------------\n" << endl;

delete[] symbol;

} while((ri->Next(level)));

}
