getScreens

Get Screens can be used to capture screen shots of entire desktop or specified regions of the desktop. These screen shots can be saved in JPG/PNG formats. Another functionality of Get Screens is to create videos out of JPG files.

This can be downloaed from https://sourceforge.net/projects/getscreens/

As of now, Quicktime, MPEG, AVI are supported.

Get Screens uses JMF 2.1.1e [Java Media Framework] for movie generation. As entire code is written in Java, Get Screens can work on all platforms. JMF can be downloaded from http://www.oracle.com/technetwork/java/javase/download-142937.html

Installation of JMF:
You can find more information at JMF at http://www.oracle.com/technetwork/java/javase/tech/index-jsp-140239.html .
To use Get Screens, it is enough that the jars[jmf.jar] of JMF are in the JAVA classpath.

Usage :

Mainly there are two utility classes.
1] CaptureScreen
2] MovieMaker

getscreens-0.1.jar needs to be in the CLASSPATH, to access the utility classes.

CaptureScreen:
-------------

As the name suggests, this class allows you to capture screen shots of the Desktop programatically.

Sample Code:
-----------
import java.awt.AWTException;
import java.io.File;
import java.io.IOException;

import com.sirisoft.image.Constants;
import com.sirisoft.image.CaptureScreen;

public class CaptureTest {
public static void main(String[] args) throws AWTException {
String fileFormat = Constants.JPG;
File outDir = new File("/tmp/images");
outDir.mkdirs();
CaptureScreen cs = new CaptureScreen(fileFormat, outDir, 1);
try {

for(int i = 0; i < 10; i++){
System.out.println("########Start");
cs.capture("cs" + i);
System.out.println("########Stop");
}
} catch (IOException e) {
e.printStackTrace();
}
}
}

Copy paste this code into CaptureTest.java,
Change the output directory appropriately,
Save and run the below commands in the command prompt.

javac -cp getscreens-0.1.jar CaptureTest.java
java -cp getscreens-0.1.jar CaptureTest

Then you will see some images created in the output directory with names cs1.jpg, cs2.jpg ...


MovieMaker:
----------

This class is used to create movie files from JPG files.

Sample Code:
-----------
import java.io.File;
import com.sirisoft.image.MovieMaker;
import com.sirisoft.image.Constants;

public class MovieTest {

public static void main(String[] args) {

File ipDir = new File("/tmp/images/");

MovieMaker movieMaker = new MovieMaker(ipDir, Constants.JPG);

movieMaker.generateQuickTimeMovie(1280, 800, 1, "/tmp/b.mov");
//movieMaker.generateMPEGMovie(1280, 800, 1, "/tmp/b.mov");
//movieMaker.generateAVIMovie(1280, 800, 1, "/tmp/b.avi");
}
}

Copy this code into MovieTest.java,
Change the input and output directories appropriately,
Change the image width, height appropriately,
and run the following commands.

javac -cp jmf.jar:getscreens-0.1.jar MovieTest.java
java -cp jmf.jar:getscreens-0.1.jar MovieTest

If everything worked fine, you should be able to see a .mov file in the output directory. Play it in your favourite video player.

Read the API documentation for more convenience methods for invoking these two utility classes.
