Extract Text from Image with skew correction

		// The image path
		String imagePath = "p3.png";

		//Create api instance
		AsposeOCR api = new AsposeOCR();

		// Set preprocessing filters to rotate image before recognition.
		PreprocessingFilter filters = new PreprocessingFilter();
		filters.add(PreprocessingFilter.AutoSkew());

		// Create OcrInput object and add images/documents for recognition
		OcrInput input = new OcrInput(InputType.SingleImage, filters);
		input.add(imagePath);

		// Recognize page by full path to file
		ArrayList<RecognitionResult> result = api.Recognize(input);
		System.out.println("Result: " + result.get(0).recognitionText);
