Recognize TIFF images

Recognize TIFF images

Aspose.OCR for Java provides the RecognizeTIFF method that can recognize text on the images extracted from multipage TIFF files. The RecognizeTIFF method takes the TIFF path as a parameter and DocomentRecognitionSettings object. You have to set the number of pages for recognition in the DocomentRecognitionSettings constructor or using setter. 0 means all pages will recognize. The following code snippet demonstrates the use of the RecognizeTiff method to recognize images from multipage TIFF file.

Sample Code

...

	// For complete examples and data files, please go to https://github.com/aspose-ocr/Aspose.OCR-for-Java
	// The path to the documents directory.
	String dataDir = Utils.getSharedDataDir(PerformOCROnPage.class);

	// The image path
	String imagePath = dataDir + "p3.tiff";

	// Initialize an instance of AsposeOcr
	 AsposeOCRPdf api = new AsposeOCR();

        // Set license 
        License.setLicense("Aspose.Total.lic");

       // settings (set the pages amount in constructor). 
		DocumentRecognitionSettings set = new DocumentRecognitionSettings(1);
		set.setStartPage(2);
		
		// Recognize images from TIFF 
		ArrayList<RecognitionResult> result = api.RecognizeTiff(imgPath, set);
		
		// result
		for(RecognitionResult page : result) {
			System.out.print("PAGE: ");
			printResult(page);
		}
    }
    
    static void printResult(RecognitionResult result) {
    	//TEXT
    	System.out.println("TEXT:\n" + result.recognitionText);
    	
    	//SKEW
    	System.out.print("SKEW: ");
    	System.out.println(result.skew);
    	
    	//PARAGRAPHS
    	System.out.println("\nPARAGRAPHS:");    	
    	for (String paragraph : result.recognitionAreasText){
    		System.out.println(paragraph);
    	}
    	
     	//PARAGRAPHS COORDS
    	System.out.println("PARAGRAPHS COORDS:");
    	for (Rectangle rectangle : result.recognitionAreasRectangles){
    		System.out.println("X: " + rectangle.x + "Y: " + rectangle.y + "Width: " + rectangle.width + "Height: " + rectangle.height);
    	}
    	
    	//LINES
    	System.out.println("LINES:");
    	for (LinesResult line : result.recognitionLinesResult){
    		System.out.print("X: " + line.line.x + "Y: " + line.line.y + "Width: " + line.line.width + "Height: " + line.line.height);
    		System.out.println(" " + line.textInLine);
    	}
    	
    	//POSSIBLE CHOICES FOR CHARACTERS
    	System.out.println("POSSIBLE CHOICES FOR CHARACTERS:");
    	for (char[] choices : result.recognitionCharactersList){
    		System.out.println("character: " + choices[0] + " " + choices[1] + " " + choices[2] + " " + choices[3] + " " + choices[4]);
    	}    	
    	
    	//WARNINGS
    	System.out.println("WARNINGS:");
    	for (String warning : result.warnings){
    		System.out.print(warning);
    	}
    	
    	//JSON
    	System.out.println("JSON:");
    	System.out.print(result.GetJson());
    	
    	//SPELL-CHECK CORRECTED TEXT
    	System.out.println("SPELL-CHECK CORRECTED TEXT:");
    	System.out.print(result.getSpellCheckCorrectedText());
    }
