Returns error code (returns 0 if the function operates successfully).
You can call GetErrorString to get detailed error message.
Code Snippet
CLabelRecognition* recognizer = new CLabelRecognition();
recognizer->InitLicense("t0260NwAAAHV***************");
//Generate imageData from somewhere else
int errorCode = recognizer->RecognizeByBuffer(imageData, "");
delete recognizer;
RecognizeByFile
