Public API changes and backwards compatibility

This section lists all public API changes introduced in Aspose.OCR for C++ 22.11.0 that may affect the code of existing applications.

Added public APIs:

The following public APIs have been introduced in this release:


Added a new areas detection mode detect_areas_mode_enum::CURVED_TEXT which uses a specialized neural network that automatically tracks and rectifies curved lines of text. This improves recognition accuracy and allows much more text to be recovered and extracted.

No changes.

Usage examples

The examples below illustrates the changes introduced in this release:


const string image = "source.jpg";
// Prepare buffer for result (in symbols, len_byte = len * sizeof(wchar_t))
const size_t len = 4096; 
wchar_t buffer[len] = { 0 };
// Activate curved text corrections
RecognitionSettings settings;
settings.detect_areas_mode = detect_areas_mode_enum::CURVED_TEXT;
// Read image
size_t size = asposeocr_page_settings(image.c_str(), buffer, len, settings);
#ifdef _WIN32
	setmode(_fileno(stdout), 0x00020000);
	setlocale(LC_CTYPE, "");
	std::wcout << buffer;
