Move Slide to New Position using Apache POI and Aspose.Slides

Aspose.Slides - Move Slide to New Position

If you create a presentation using MS PowerPoint, you would have experienced that whenever you add a new slide to your presentation, it is appended at the end of the presentation by default. Using MS PowerPoint, you can drag a selected slide to any other position of the presentation. Aspose.Slides for Java also allows developers to change the position of a slide within the presentation.

It’s very simple to change the position of a slide in the presentation. Just follow the steps below:

  • Create an instance of Presentation class
  • Obtain the reference of a slide by using its Index
  • Change the SlideNumber of the referenced slide
  • Write the modified presentation file
//Instantiate a Presentation object that represents a PPT file
Presentation pres = new Presentation("presentation.ppt");

//Accessing a slide using its slide position
ISlide slide = pres.getSlides().get_Item(0);

//Change the position of the selected slide
slide.setSlideNumber(2);

Apache POI SL - HSLF XSLF - Move Slide to New Position

XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("presentation.pptx"));

//add slides

...
