Aspose.Slides - Add Slides to Presentation

Aspose.Slides for Java allows developers to add empty slides to their presentation. To add an empty slide in the presentation, please follow the steps below:

  • Create an instance of Presentation class
  • Instantiate ISlideCollection class by setting a reference to the Slides (collection of content Slide objects) property exposed by the Presentation object.
  • Add an empty slide to the presentation at the end of the content slides collection by calling the AddEmptySlide method exposed by ISlideCollection object
  • Do some work with the newly added empty slide
  • Finally, write the presentation file using the Presentation object
//Instantiate a PresentationEx object that represents a PPTX file
Presentation pres = new Presentation("presentation.pptx");

//Add Slide
ISlide slide = pres.getSlides().addEmptySlide(pres.getLayoutSlides().get_Item(0));
