Aspose.OCR for C++ 24.7.0 - Release Notes

What was changed

Public API changes and backwards compatibility

This section lists all public API changes introduced in Aspose.OCR for C++ 24.7.0 that may affect the code of existing applications.

Added public APIs:

The following public APIs have been added in Aspose.OCR for C++ 24.7.0 release:

detect_areas_mode_enum::UNIVERSAL

A new document areas detection algorithm, detect_areas_mode_enum::UNIVERSAL was added to the API.

On average, this algorithm achieves good results with most image types and can be considered as an optimal choice for general image processing. However, specialized algorithms can provide faster or more accurate results for their intended use cases.

Updated public APIs:

The following public APIs have been changed in Aspose.OCR for C++ 24.7.0 release:

detect_areas_mode_enum::MIXED_TEXT

This API replaces the existing detect_areas_mode_enum::COMBINE. The original value is marked as deprecated and will be removed in 25.1.0 (January 2025) release.

Removed public APIs:

No changes.

Deprecated APIs

The following public APIs have been marked as deprecated and will be removed in 25.1.0 (January 2025) release:

detect_areas_mode_enum::COMBINE

Use a newly added detect_areas_mode_enum::MIXED_TEXT instead.

Examples

The code samples below illustrate the changes introduced in this release:

Universal document areas detection mode

// Provide the image
string file = "source.png";
AsposeOCRInput source;
source.url = file.c_str();
std::vector<AsposeOCRInput> content = { source };
// Fine-tune recognition
RecognitionSettings settings;
settings.detect_areas_mode = detect_areas_mode_enum::UNIVERSAL;
// Extract text from the image
auto result = asposeocr_recognize(content.data(), content.size(), settings);
// Output the recognized text
wchar_t* buffer = asposeocr_serialize_result(result, buffer_size, export_format::text);
std::wcout << std::wstring(buffer) << std::endl;
// Release the resources
asposeocr_free_result(result);
