#include <leptonica/allheaders.h>
  1. Create a new instance of the Tesseract library and set the language.
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
api->Init(NULL, "eng");
  1. Read the image file into a Pix object.
Pix *image = pixRead("example.png");
  1. Set the image for the Tesseract library instance.
  1. Extract the text from the image.
