Example (C++17 since filesystem)

#include <iostream>
#include <aspose_ocr.h>
#include <filesystem>
#include <corecrt_io.h>
#include <fcntl.h>
int main()
_setmode(_fileno(stdout), _O_U16TEXT);
//Current directory const
std::filesystem::path path{ std::filesystem::current_path() };
/* asposeocr_set_license */
const std::string lic = "/Aspose.Total.lic";
std::filesystem::path license = path.string() + lic;
/* asposeocr_set_license */
bool lic_result = asposeocr_get_state();

//Get words rectangles

const string image = "img.jpg";

	// Prepare buffer for result (in symbols, len_byte = len * sizeof(wchar_t))
	const size_t len = 4096;
    wchar_t buffer[len] = { 0 };
	//Set parameters for recognition 
    RecognitionSettings settings;
    settings.all_image = true;

    size_t res = aspose::ocr::get_rectangles_number(image.c_str(), areas_type::words, true);  
    std::wcout << res;

    rect * r = new rect[res];
    res = aspose::ocr::get_rectangles(image.c_str(), areas_type::paragraphs, true, r, res);
    std::wcout << res;
    for (size_t i = 0; i < res; i++)
        cout <<"x:"<< r[i].x << " y:" << r[i].y << " height:" << r[i].width << " width:" << r[i].height << endl;
	delete [] r;
