Apache POI PPT - Merging
You can merge multiple presentations using the importContent() method of the XMLSlideShow class. Given below is the complete program to merge two presentations −
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.XSLFSlide; public class MergingMultiplePresentations { public static void main(String args[]) throws IOException { //creating empty presentation XMLSlideShow ppt = new XMLSlideShow(); //taking the two presentations that are to be merged String file1 = "presentation1.pptx"; String file2 = "presentation2.pptx"; String[] inputs = {file1, file2}; for(String arg : inputs){ FileInputStream inputstream = new FileInputStream(arg); XMLSlideShow src = new XMLSlideShow(inputstream); for(XSLFSlide srcSlide : src.getSlides()) { //merging the contents ppt.createSlide().importContent(srcSlide); } } String file3 = "combinedpresentation.pptx"; //creating the file object FileOutputStream out = new FileOutputStream(file3); // saving the changes to a file ppt.write(out); System.out.println("Merging done successfully"); out.close(); } }
Save the above code as MergingMultiplePresentations.java, and then compile and execute it from the command prompt as follows −
$javac MergingMultiplePresentations.java $java MergingMultiplePresentations
It will compile and execute to generate the following output −
Merging done successfully
The following snapshot shows the first presentation −
The following snapshot shows the second presentation −
Given below is the output of the program after merging the two slides. Here you can see the content of the earlier slides merged together.
