Aspose.OCR for CPP 22.3 Release Notes

All Features

OCRCPP-245Import Craft model and get the resultEnhancement
OCRCPP-241Import optimized modelsEnhancement


  • reduced package size
  • added ability to choose mode of areas detection

Public API and Backwards Incompatible Changes



NONE - Doesn’t detect paragraphs. Better for a simple one-column document without pictures.

DOCUMENT = Detects paragraphs uses NN model for documents. Better for multicolumn document, document with pictures or with other not text objects.
PHOTO = Detects paragraphs uses NN model for photos. Better for image with a lot of pictures and other not text objects.
COMBINE = Detects paragraphs with text and then uses other NN model to detect areas inside of paragraphs. Better for images with complex structure.

detect_areas_mode_enum detect_areas_mode

Field in RecognitionSettings structure. Default value: detect_areas_mode_enum::DOCUMENT

Removed APIs

No Changes

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();

//Recognize image

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 };

/* asposeocr_page_settings*/

RecognitionSettings settings;
    settings.detect_areas_mode = detect_areas_mode_enum::COMBINE;

    size_t size = asposeocr_page_settings(image.c_str(), buffer, len, settings);
#ifdef _WIN32
    setmode(_fileno(stdout), 0x00020000);
    setlocale(LC_CTYPE, "");
    std::wcout << buffer;
