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);
  • BMP What is BMP File Format

    Files having extension .BMP represent Bitmap Image files that are used to store bitmap digital images. These images are independent of graphics adapter and are also called device independent bitmap (DIB) file format. This independency serves the purpose of opening the file on multiple platforms such as Microsoft Windows and Mac. The BMP file format can store data as two-dimensional digital images in both monochrome as well as color format with various colour depths.
