Apache POI Delete Slide

To delete powerpoint slide, Apache POI provides a method removeSlide(). It takes slide's index as an argument. Slide index starts with 0, so that first slide can be accessed by passing 0 to this method.

Lets see an example in which we are deleting first slide from the group of slides.

Apache POI Delete Slide Example

package poiexample;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
public class DeleteSlideExample {
	public static void main(String[] args) {
	    try (XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("Javatpoint.pptx"))) {
		  ppt.removeSlide(0);
		  FileOutputStream out = new FileOutputStream("Javatpoint.pptx");
		  ppt.write(out);
	    }catch(Exception e) {
	    	System.out.println(e);
	    }
	}
}

Output:

See, before deleting slide, we have three slides in this document.
