Recognition

Reading text from any content in Aspose.OCR for C++ is as easy as calling a universal asposeocr_recognize() function.

This function takes a sequence of OcrInput objects and optional recognition settings.

Recognition results are returned as a AsposeOCRRecognitionResult structure, that allow you to get image text and save results in various formats.

Releasing resources

Once you have performed all the required operations with the AsposeOCRRecognitionResult structure, it is recommended to release the allocated memory by calling asposeocr_free_result() function.

Example

The following code example shows how to extract text from multiple images:

// Provide images
string file = "page1.png";
AsposeOCRInput source1;
source1.url = file.c_str();
string file = "page2.png";
AsposeOCRInput source2;
source2.url = file.c_str();
std::vector<AsposeOCRInput> content = { source1, source2 };
// Fine-tune recognition
RecognitionSettings settings;
settings.language_alphabet = language::ukr;
// 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);
