Hello JRuby People,

I’m not quite ready to JRubyify yet but,  
I’m working on a mini-project which requires that I screen-capture a  
portion of my x-display on a linux box.

It looks like I can use a class in Java named “Robot” to do this:

- [Robot (Java Platform SE 6)](http://java.sun.com/javase/6/docs/api/java/awt/Robot.html)

I figure any class (even if it is a Java class) named “Robot” deserves  
my attention.

So I ran this query:

- [java robot screencapture - Google Search](http://www.google.com/search?q=java+robot+screencapture)

And this page looks good:

- [Get a screen capture and save it as a JPEG - Real's Java How-to](http://www.rgagnon.com/javadetails/java-0489.html)

I see this example:

import java.awt.AWTException;  
import java.awt.Robot;  
import java.awt.Rectangle;  
import java.awt.Toolkit;  
import java.awt.image.BufferedImage;  
import [java.io](http://java.io).\*;  
import javax.imageio.ImageIO;

class ScreenCapture {  
public static void main(String args[]) throws  
AWTException, IOException {  
// capture the whole screen  
BufferedImage screencapture = new Robot().createScreenCapture(  
new Rectangle(Toolkit.getDefaultToolkit().getScreenSize  
()) );

```
 // Save as JPEG
 File file = new File("screencapture.jpg");
 ImageIO.write(screencapture, "jpg", file);

 // Save as PNG
 // File file = new File("screencapture.png");
 // ImageIO.write(screencapture, "png", file);

```

}  
}

My question:  
Is it possible to transform the above Java-syntax into Ruby-syntax  
which could be interpreted by JRuby?

Or I could ask it this way:  
How do I transform the above Java-syntax into JRuby-syntax?

–Audrey

Dear Audrey,

you can use Java classes in Jruby straight away:

[http://blogs.sun.com/coolstuff/entry/using\_java\_classes\_in\_jruby](http://blogs.sun.com/coolstuff/entry/using_java_classes_in_jruby)

For Linux automation, you might want to look at (the non-Java)  
xdotool and its Ruby gem binding xdo:

You might combine that with one of the many ways to take screenshots  
in Linux:
