Aspose.OCR for Java 21.7 - Release Notes

This page contains release notes information for Aspose.OCR for Java 21.7

GPU version: 21.6.0

All Features

Key	Summary	Category
OCRJAVA-141	Add a method that returns a list of rectangles of all lines in the text	Enhancement
OCRJAVA-143	Confidence rating of potential match	Enhancement
OCRJAVA-138	Add new method (or parameter) that indicates the table exists on the image	Enhancement

Enhancements

The next opportunities:

• added new parameters in the method getTextAreas: AreasType areasType and boolean isDetectAreas
• added new property in the RecognitionSettings class that indicates the table exists on the image
• added new property in the RecognitionResult class: recognitionCharactersList
• used compressed OCR ML model and reducing the packet size

Public API and Backwards Incompatible Changes

New API

• added method: ArrayList getTextAreas(BufferedImage image_, AreasType areasType, boolean isDetectAreas)
• added method: ArrayList getTextAreas(String fullPath, AreasType areasType, boolean isDetectAreas)
• added enum AreasType
• added property: ArrayList<char[]> recognitionCharactersList to the RecognitionResult class
• added property: boolean linesFiltration = false to the RecognitionSettings class

Removed APIs

• ArrayList getTextAreas ()

Will be deprecated

• none

Usage Example

import static java.lang.System.out;

import java.awt.Rectangle;
import java.io.IOException;

import com.aspose.ocr.AsposeOCR;
import com.aspose.ocr.License;
import com.aspose.ocr.RecognitionResult;
import com.aspose.ocr.RecognitionSettings;
import com.aspose.ocr.SaveFormat.Format;


public class App {
       public static void main(String[] args) {

        // set license    

        License.setLicense("Aspose.Total.lic");
        boolean resLicense = License.isValid();
        out.println("License is :" + resLicense);

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

        String img= "img.png";		
		
		// recognize table
        RecognitionSettings settings = new RecognitionSettings();	
		settings.setLinesFiltration(true);	
		RecognitionResult result = api.RecognizePage(file, settings);
		
		System.out.println(result.recognitionText);	
		
		// get probabilities for the first character
		for(int i = 0; i < 5; i++) {
            	System.out.println(result.recognitionCharactersList.get(0)[i]);
        }
		
		// get lines coordinates from image
		 ArrayList<Rectangle> res = api.getTextAreas(resFile.getFile(), AreasType.LINES, true);
		 
		// print first line coordinates
		 System.out.println(res.get(0).x);
		 System.out.println(res.get(0).y);
		 System.out.println(res.get(0).width);
		 System.out.println(res.get(0).height);
