OcrInput source = new OcrInput(InputType.SingleImage);
source.add("image.png");
// Specify recognition language
RecognitionSettings recognitionSettings = new RecognitionSettings();
recognitionSettings.setLanguage(Language.Ara);
// Extract text from image
ArrayList<RecognitionResult> results = api.Recognize(source, recognitionSettings);
System.out.println(result[0].recognition_text);
Saving recognition results into stream
// Initialize Aspose.OCR recognition API
AsposeOCR api = new AsposeOCR();
// Add scanned PDF to the recognition batch
OcrInput source = new OcrInput(InputType.PDF);
source.add("scan.pdf");
// Saving searchable PDF into stream
ArrayList<RecognitionResult> results = api.Recognize(source);
OutputStream stream = new ByteArrayOutputStream();
AsposeOCR.SaveMultipageDocument(stream, Format.Pdf, results);
