DocumentRecognitionSettings recognitionSettings = new DocumentRecognitionSettings();
recognitionSettings.setLanguage(Language.Ukr);
// Extract text from multi-page TIFF
InputStream inputStream = new FileInputStream("source.tiff");
ArrayList<RecognitionResult> results = api.RecognizeTiff(inputStream, recognitionSettings);
results.forEach((page) -> {
	System.out.println(page.recognitionText);
});

Recognize of in-memory receipt image

AsposeOCR api = new AsposeOCR();
BufferedImage source = ImageIO.read(new File("receipt.png"));
// Customize recognition
ReceiptRecognitionSettings recognitionSettings = new ReceiptRecognitionSettings();
recognitionSettings.setLanguage(Language.Ukr);
// Extract text from receipt
RecognitionResult result = api.RecognizeReceipt(source, recognitionSettings);
// Get recognition results as JSON
String resultJson = result.GetJson();

AsposeOCR api = new AsposeOCR();
// Customize recognition
DocumentRecognitionSettings recognitionSettings = new DocumentRecognitionSettings();
recognitionSettings.setLanguage(Language.Ukr);
// Extract text from PDF document
ArrayList<RecognitionResult> results = api.RecognizePdf("source.pdf", recognitionSettings);
results.forEach((page) -> {
	System.out.println(page.recognitionText);
});
