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);
});

Read PDF from memory

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