Aspose.OCR  for Java


Add Optical Character Recognition and Document Scanning Functionality to any Java-based OCR application.

  Download Free Trial

Aspose.OCR for Java is a stand-alone OCR API for Java applications while allowing the developers to perform optical character recognition on commonly used image types. It provides a simple set of classes to control character recognition for various language characters. Developers can easily read characters in multiple fonts, rotated images, whole images or parts of images. Furthermore, API has the capability to perform OCR through GPU instead of the core processor.

Image to Text Java API Features

Read different characters from images

Support for common image formats

Scan any part of an image or as a whole

Scan rotated images

Read the text in multiple fonts

Support for common font styles

Get skew angle of images

Perform OCR On Image Selected Areas

Using the library, developers can extract text from image specific parts by specifying rectangles, fonts, and styles. Recognizing text in pixels from images specific areas is simple, with just a few lines of code.

Perform OCR on selected areas - Java

//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);

Recognize Text in Different Fonts

Aspose.OCR for Java API supports Times New Roman, Arial, Verdana, Courier New, Tahoma and Calibri fonts in regular, italic and bold text styles as well as different language characters.

Easy to Calculate Skew Angle

Using the Java OCR library, calculating the image skew angle is fast and simple. Developers can use CalcSkewImage function by providing image path that returns the skew angle.

Calculate Skew Angle of the Image - Java

//Create api instance

AsposeOCR api = new AsposeOCR();

// Get skew

double angle = api.CalcSkewImage("sourceImage.png");

System.out.println("Skew text is:" + angle + " degrees.");
