need more details. java contains libraries for barcode reading but cant help.coz ur question s not clear.. u jus wanna read a bar code?

 

[akhilapraveen]

01.InputStream barCodeInputStream = new FileInputStream("file.jpg");02.BufferedImage barCodeBufferedImage = ImageIO.read(barCodeInputStream);
03.
04.LuminanceSource source = new BufferedImageLuminanceSource(barCodeBufferedImage);
05.BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
06.Reader reader = new MultiFormatReader();
07.Result result = reader.decode(bitmap);
08.
09.System.out.println("Barcode text is " + result.getText());



THIS IS HOW YOU NORMALY READ A BARCODE

Ya machan you can do it! There are 2 ways to do t
1.microchip programming.
2.Picture scanning

Second one is the easiest way and its used by many phone applications

Ill explain how to do t,

First Download Library file from here
http://code.google.com/p/zxing/downloads/detail?name=ZXing-1.6.zip&can=2&q=
(hope you know how to import a lib file)
//-------------------------------------------------------------------
InputStream barCodeInputStream = new FileInputStream("file.jpg");
BufferedImage barCodeBufferedImage = ImageIO.read(barCodeInputStream);

LuminanceSource source = new BufferedImageLuminanceSource(barCodeBufferedImage);
BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
Reader reader = new MultiFormatReader();
Result result = reader.decode(bitmap);

System.out.println("Barcode text is " + result.getText());
//-------------------------------------------------------------


IF YOU WANNA WRITE A BARCODE FROM JAVA, THIS IS HOW YOU DO IT

String text = "98376373783"; // this is the text that we want to encode

int width = 400;
int height = 300; // change the height and width as per your requirement

// (ImageIO.getWriterFormatNames() returns a list of supported formats)
String imageFormat = "png"; // could be "gif", "tiff", "jpeg"

BitMatrix bitMatrix = new QRCodeWriter().encode(text, BarcodeFormat.QR_CODE, width, height);
MatrixToImageWriter.writeToStream(bitMatrix, imageFormat, new FileOutputStream(new File("qrcode_97802017507991.png")));



HOPE THIS WILL HELP YOU IN SOME WAY!

1. you can add a URL reading method and get all links for a web page
then you can divide all pictures links and download them to your software.

2.or you can easliy use a web browser to show the locations you searched

for that you can use your default browser or a browser you developed.
I have developed some browsers i can give it to you,if you want BUT i realy recomnd to use the default browser coz its way faster than the browser you developed.

ok now heres the coding

first create a class called WEBBROWSER and enter the following coding



//--------------------------------------------------------------

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JOptionPane;
import java.util.Arrays;

public class WEBBROWSER{
static final String[] browsers = { "google-chrome", "firefox", "opera", "epiphany", "konqueror", "conkeror", "midori", "kazehakase", "mozilla" };
static final String errMsg = "Error attempting to launch web browser";

public static void openURL(String url) {
try {
//attempt to use Desktop library from JDK 1.6+
Class<?> d = Class.forName("java.awt.Desktop");
d.getDeclaredMethod("browse", new Class[] {java.net.URI.class}).invoke( d.getDeclaredMethod("getDesktop").invoke(null), new Object[] {java.net.URI.create(url)});
//above code mimicks: java.awt.Desktop.getDesktop().browse()
}
catch (Exception ignore) {
//library not available or failed
String osName = System.getProperty("os.name");
try {
if (osName.startsWith("Mac OS")) { Class.forName("com.apple.eio.FileManager").getDeclaredMethod( "openURL", new Class[] {String.class}).invoke(null, new Object[] {url});
}
else if (osName.startsWith("Windows")) Runtime.getRuntime().exec( "rundll32 url.dll,FileProtocolHandler " + url);
else {
//assume Unix or Linux
String browser = null;
for (String b : browsers) if (browser == null && Runtime.getRuntime().exec(new String[] {"which", b}).getInputStream().read() != -1) Runtime.getRuntime().exec(new String[] {browser = b, url});
if (browser == null) throw new Exception(Arrays.toString(browsers));
}
}
catch (Exception e) { JOptionPane.showMessageDialog(null, errMsg + "\n" + e.toString()); } } } }

//-------------------------------------------------------------------

Now create a object of this class and call tha method as following.


String searchkeyword;
String searchkeyword2;

searchkeyword="ENTER THE PLACE YOU WANNA SEARCH HERE"


searchkeyword2=http://www.nationsonline.org/oneworld/map/google_map_+searchkeyword+.htm;

YOU CAN USE ANY SITE THAT PROVIDES GOOGLE MAPS HERE


WEBBROWSER page1=new WEBBROWSER();
page1.openURL(searchkeyword2);

HOPE THIS WILL HELP YOU

Na brother. ur wrng! to read a simple barcode camera is enough! im not talkin about high level barcode systems.. but barcode is just a picture! it has data hidden all over it! lik a encrypted message!
