I have formated my string to be output via putText() as follows;

String predictedResult = "1. Name :"+resultRetrieved[4] + "\r\n"+ "2. ID :"+resultRetrieved[5] + "\r\n";

in putText() I pass

predictedResult

and I expect to have these two lines

Name: Joseph Mwema
ID: IDTEST001

but I end up having this one liner

Name: Joseph Mwema?? ID: IDTEST001??

How can I get this fixed? I am developing my application using java. Someone kindly show me how to do this correctly?

putText() does no linefeed, for 3 lines of text, you need 3 putText calls(at digfferent x,y locations).

also, it can handle only a small ascii subset, for any unrecognized char you get a '?',

Oh! let me try with 3 putText() functions.

double fontScale = 2; Scalar color = new Scalar(fontScale); Point pointXY1 = new Point(10, 10); Point pointXY2 = new Point(10, 30); putText(imgMat, "Name :"+resultRetrieved[4], pointXY1 , FONT_HERSHEY_PLAIN, 0.8, color, 1, CV_AA, false); putText(imgMat, "ID :"+resultRetrieved[5], pointXY2 , FONT_HERSHEY_PLAIN, 0.8, color, 1, CV_AA, false);

you can use the '10101' button to format code nicely here ;)
