Save to file

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input);
// Save result
results[0].Save("result.txt", Aspose.OCR.SaveFormat.Text);

Write to memory

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input);
// Save result
using(MemoryStream ms = new MemoryStream())
{
	results[0].Save(ms, Aspose.OCR.SaveFormat.Text);
}

Saving recognition results as a multi-page document

You can merge several recognition results into one document using SaveMultipageDocument method of Aspose.OCR.AsposeOcr class. This can be useful for recognizing books, contracts, articles, and other printouts consisting of multiple pages, as well as for batch recognition.

You can optionally enable automatic spelling corrections for recognition results and provide a custom dictionary.

Save to file

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add images to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("page1.png");
input.Add("page2.png");
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input);
// Save results
Aspose.OCR.AsposeOcr.SaveMultipageDocument("result.docx", Aspose.OCR.SaveFormat.Docx, results);

Write to memory

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add images to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("page1.png");
input.Add("page2.png");
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input);
// Save results
using(MemoryStream ms = new MemoryStream())
{
	Aspose.OCR.AsposeOcr.SaveMultipageDocument(ms, Aspose.OCR.SaveFormat.Docx, results);
}
