Add layout Slide to Presentation

Aspose.Slides for .NET allows developers to add new Layout slides in presentation. To add a Layout Slide, please follow the steps below:

  • Create an instance of Presentation class
  • Access the Master Slide collection
  • Try to find existing Layout slides to see if the required one is already available in Layout Slide collection or not
  • Add a new Layout slide if the desired layout is unavailable
  • Add an empty slide with newly added Layout slide
  • Finally, write the presentation file using the Presentation object.

Example


 //Instantiate Presentation class that represents the presentation file

using (Presentation p = new Presentation("Test.pptx"))

{

   // Try to search by layout slide type

   IMasterLayoutSlideCollection layoutSlides = p.Masters[0].LayoutSlides;

   ILayoutSlide layoutSlide =

   layoutSlides.GetByType(SlideLayoutType.TitleAndObject) ??

   layoutSlides.GetByType(SlideLayoutType.Title);

   if (layoutSlide == null)

   {

     // The situation when a presentation doesn't contain some type of layouts.

     // Technographics.pptx presentation only contains Blank and Custom layout types.

     // But layout slides with Custom types has different slide names,

     // like "Title", "Title and Content", etc. And it is possible to use these

     // names for layout slide selection.

     // Also it is possible to use the set of placeholder shape types. For example,

     // Title slide should have only Title pleceholder type, etc.

     foreach (ILayoutSlide titleAndObjectLayoutSlide in layoutSlides)

     {

       if (titleAndObjectLayoutSlide.Name == "Title and Object")

       {

          layoutSlide = titleAndObjectLayoutSlide;

          break;

       }

      }

      if (layoutSlide == null)

      {

         foreach (ILayoutSlide titleLayoutSlide in layoutSlides)

         {

            if (titleLayoutSlide.Name == "Title")

            {

                layoutSlide = titleLayoutSlide;

                break;

            }

          }

          if (layoutSlide == null)

          {

             layoutSlide = layoutSlides.GetByType(SlideLayoutType.Blank);

             if (layoutSlide == null)

             {

                  layoutSlide = layoutSlides.Add(SlideLayoutType.TitleAndObject, "Title and Object");

             }

          }

      }

  }

  //Adding empty slide with added layout slide

  p.Slides.InsertEmptySlide(0, layoutSlide);

  //Save presentation

  p.Save("Output.pptx", SaveFormat.Pptx);

}
