You can get a count of the number of shapes used in a presentation using the method getShapeName() of the XSLFShape class. Given below is the program to read the shapes from a presentation −

import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException; import org.apache.poi.xslf.usermodel.XMLSlideShow;import org.apache.poi.xslf.usermodel.XSLFShape;import org.apache.poi.xslf.usermodel.XSLFSlide; public class ReadingShapes {    public static void main(String args[]) throws IOException {       //creating a slideshow       File file = new File(“shapes.pptx”);      XMLSlideShow ppt = new XMLSlideShow(new FileInputStream(file));       //get slides       XSLFSlide[] slide = ppt.getSlides();       //getting the shapes in the presentation      System.out.println(“Shapes in the presentation:”);      for (int i = 0; i < slide.length; i++){          XSLFShape[] sh = slide[i].getShapes();         for (int j = 0; j < sh.length; j++){             //name of the shape            System.out.println(sh[j].getShapeName());         }      }       FileOutputStream out = new FileOutputStream(file);      ppt.write(out);      out.close();   }}

Save the above Java code as ReadingShapes.java, and then compile and execute it from the command prompt as follows −

$javac ReadingShapes.java$java ReadingShapes

It will compile and execute to generate the following output.

Shapes in the presentation: Rectangle 1Oval 1Isosceles Triangle 1

The newly added slide with the various shapes appears as follows −
