Aspose.Imaging for Java

processes scanned images or even smartphone photos in JPEG format and creates JPEG documents containing recognized text. To add it to your project, you just need to get Aspose.OCR

Aspose Maven Repository or specify Aspose Maven Repository configuration and install it within your Maven-based project by adding the following configurations to the pom.xml. For Graddle, Ivy, Sbt examples check out our repository .

Maven Dependency


 <dependency>
 <groupId>com.aspose</groupId>
 <artifactId>aspose-ocr</artifactId>
 <version>22.5</version>
 </dependency>

With Java OCR and just a few lines of code, you can create full-featured application that converts an JPEG image to PDF document:

  • Create an instance of AsposeOcr class
  • Call AsposeOCR.RecognizePage method
  • Pass the JPEG file path as parameter
  • AsposeOCR.RecognizePage returns a String or file of PDF type

System Requirements

Before running the example, make sure that Java 2 Platform, Standard Edition (J2SE) 6.0 (1.6) or later is installed on your system.

  • JDK 1.6 or higher is installed.


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

 //Prepare rectangles with texts.
 ArrayList rectArray = new ArrayList();

 rectArray.add(new Rectangle(138, 352, 2033, 537));
 rectArray.add(new Rectangle(147, 890, 2033, 1157));

 String result = api.RecognizePage("srcImage.png", rectArray);
 System.out.println("Result with rect: " + result);
  • JPEG What is JPEG File Format

    A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.

    PDF What is PDF File Format

    Portable Document Format (PDF) is a type of document created by Adobe back in 1990s. The purpose of this file format was to introduce a standard for representation of documents and other reference material in a format that is independent of application software, hardware as well as Operating System. The PDF file format has full capability to contain information like text, images, hyperlinks, form-fields, rich media, digital signatures, attachments, metadata, Geospatial features and 3D objects in it that can become as part of source document.
