Now, let’s break down the example into multiple steps for a comprehensive understanding.

Step 1: Set the Document Directory

Begin by specifying the path to your document directory. This is where the manipulated presentation will be saved.

string dataDir = "Your Document Directory";

using (Presentation presentation = new Presentation())
{
    // Your code goes here
}

Step 3: Set View Properties of Presentation

To adjust the zoom level, you need to set the view properties of the presentation. In this example, we’ll set the zoom value in percentages for both slide view and notes view.

presentation.ViewProperties.SlideViewProperties.Scale = 100; // Zoom value in percentages for slide view
presentation.ViewProperties.NotesViewProperties.Scale = 100; // Zoom value in percentages for notes view

Step 4: Save the Presentation

Save the modified presentation with the adjusted zoom level to the specified directory.

presentation.Save(dataDir + "Zoom_out.pptx", SaveFormat.Pptx);

Now you have successfully adjusted the zoom level for presentation slides using Aspose.Slides for .NET!
