public class SaveShapeAsImage {

    public static void main(String[] args) throws Exception {

        //Create a Presentation object
        Presentation presentation = new Presentation();

        //Load the sample PowerPoint file
        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\chart and table.pptx");

        //Get the first slide
        ISlide slide = presentation.getSlides().get(0);

        //Declare a BufferedImage variable
        BufferedImage image;

        //Loop through the shapes in the slide
        for (int i = 0; i < slide.getShapes().getCount(); i++) { //Save the specific shape as image data image = slide.getShapes().saveAsImage(i); //Write data to png file File file = new File(String.format("ToImage-%d.png", i)); ImageIO.write(image, "PNG", file); } } }
