How to take a screenshot in JAVA…

Hi all,

            Let us see how to take screenshot and save it as a JPG file with the use of Java Program. It can be acheived by the use of ImageIO API for saving the screenshot as the JPG file and to take screenshot with the Robot class. So as to proceed further, first the screen dimension should be find and we can create a rectangle with this dimension. The size of the screen can be found using the Toolkit class. The following code snippet will help you to find the screen size.

//to find the screen dimension

Toolkit toolkit = Toolkit.getDefaultToolkit();
Dimension screenSize = toolkit.getScreenSize();
Rectangle rectangle = new Rectangle(0, 0, screenSize.width, screenSize.height);

 

            After getting the screen dimension create an instance of the Robot class and copy the rectangle from the screen. The createScreenCapture() method in the Robot class can be used to get the BufferedImage of the rectangular dimension passed as argument to it. The following code snippet will help you to do the above said things.

//to get the BufferedImage with createScreenCapture method

Robot robot = new Robot();
BufferedImage image = robot.createScreenCapture(rectangle);

            So further creating the JPG file from the BufferedImage is possible through the ImageIO API to convert the BufferedImage to the JPG file. The following code snippet will help you in converting the BufferedImage to a JPG file

//convert BufferedImage to JPG File

File file = new File(“screen.jpg”);
ImageIO.write(image, “jpg”, file);
