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