std::string img_path = "../srcSample.png";

// Prepare buffer for result (in symbols, len_byte = len * sizeof(wchar_t))
const size_t len = 4096;

wchar_t bfr[len] = { 0 };

size_t result = aspose::ocr::page(image_path.c_str(), bfr, len);

//Print result
std::wcout << bfr << L"\n";
  • BMP What is BMP File Format

    Files having extension .BMP represent Bitmap Image files that are used to store bitmap digital images. These images are independent of graphics adapter and are also called device independent bitmap (DIB) file format. This independency serves the purpose of opening the file on multiple platforms such as Microsoft Windows and Mac. The BMP file format can store data as two-dimensional digital images in both monochrome as well as color format with various colour depths.

    Portable Document Format (PDF) is a type of document created by Adobe back in 1990s.
