How to set slide size for PowerPoint after cloning and merging a PowerPoint slide in C#?
Syncfusion PowerPoint is a .NET Core PowerPoint library used to create, read, and edit PowerPoint presentation programmatically without Microsoft PowerPoint or interop dependencies. When cloning and merging a PowerPoint slide from a source presentation to a destination presentation with the source formatting paste option, the slide size of the source slides may not be applied correctly to the merged slides. However, this behavior can be achieved using our library by setting the slide size for PowerPoint after cloning and merging a PowerPoint slide using C#.
Note: Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, include a license key in your projects. Refer to link to learn about generating and registering Syncfusion license key in your application to use the components without trail message. Step 3: Include the following namespaces in Program.cs file.A complete working sample to set slide size for PowerPoint after cloning and merging a PowerPoint slide using C# can be downloaded from GitHub.

Step 1: Create a new .NET console application project.
Step 2: Install the Syncfusion.Presentation.Net.Core NuGet package as a reference to your project from NuGet.org.
using Syncfusion.Presentation;
Step 4: Include the below code snippet in Program.cs to set slide size for PowerPoint after cloning and merging a PowerPoint slide.
//Open the existing source PowerPoint presentation.
using (Presentation? sourcePresentation = Presentation.Open(@"Template.pptx") as Presentation)
{ //Create a destination PowerPoint presentation.
using (Presentation? destinationPresentation = Presentation.Create() as Presentation)
{
//Set the source presentation slide size to the destination presentation slide size.
destinationPresentation.SlideSize.Type = sourcePresentation.SlideSize.Type;
destinationPresentation.SlideSize.SlideOrientation = sourcePresentation.SlideSize.SlideOrientation;
destinationPresentation.SlideSize.Width = sourcePresentation.SlideSize.Width;
destinationPresentation.SlideSize.Height = sourcePresentation.SlideSize.Height;
//Clone and merge the PowerPoint slides with PasteOptions.SourceFormatting.
foreach (ISlide slide in sourcePresentation.Slides)
destinationPresentation.Slides.Add(slide, PasteOptions.SourceFormatting);
//Save the PowerPoint Presentation.
destinationPresentation.Save("Output.pptx");
}
