A simple library for recognizing capcha images with the antigate.com service. Usage is very simple, just see the example below.

import j.antigate.*;
public class TypicalAntigate{
	 static String answer;
    public static void main (String[] args){
	try {
/** Just get an InputStream of your image in any way you want. In the example I use a local File **/
	File f = new File("C:\\capcha.png");
    	FileInputStream is = new FileInputStream(f);
    	//** You may check your antigate.com balance first **/
    	String balance = CapchaUtils.getBalance("YOURAPIKEY");
    	/** Use CapchaAnswer() method to get the capcha text, returns error message if any **/
		answer = CapchaBypass.CapchaAnswer(is, "YOURAPIKEY", null, null, null);
	} catch (IOException | InterruptedException e) {
		e.printStackTrace();
	}
    System.out.println(answer);
}
}

Method parameters are:

CapchaAnswer(InputStream, "YOURAPIKEY", "YES/NO for multiple words", "YES/NO for reg sensivity", "YES/NO for russian lang");

You can just write null for these optional parameters. If any error aperas, the CapchaAnswer() returns the error code. Here is what it means:
