Prerequisites

Before we dive into the world of extracting effective camera data, make sure you have the following prerequisites in place:

Aspose.Slides for .NET: If you haven’t installed it yet, head over to Aspose.Slides for .NET Documentation for detailed instructions on installation.
Download Aspose.Slides: You can download the latest version of Aspose.Slides for .NET from this link .
Document Directory: Ensure that you have a document directory set up to store your presentation files. Now that we have everything set up let’s jump into the action!

Import Namespaces

In your .NET project, start by importing the necessary namespaces to make Aspose.Slides functionalities available:

using Aspose.Slides;
using Aspose.Slides.Examples.CSharp;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

Step 1: Initialize Document Directory

// The path to the documents directory.
string dataDir = "Your Document Directory";
// Create directory if it is not already present.
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
    System.IO.Directory.CreateDirectory(dataDir);

Make sure to replace “Your Document Directory” with the path where you want to store your presentation files.

Step 2: Load Presentation

using (Presentation pres = new Presentation(dataDir + "Presentation1.pptx"))
{
    // Your code for further steps will go here
}

Load your presentation file using the Presentation class.

Step 3: Get Effective Camera Data

IThreeDFormatEffectiveData threeDEffectiveData = pres.Slides[0].Shapes[0].ThreeDFormat.GetEffective();
Console.WriteLine("= Effective camera properties =");
Console.WriteLine("Type: " + threeDEffectiveData.Camera.CameraType);
Console.WriteLine("Field of view: " + threeDEffectiveData.Camera.FieldOfViewAngle);
Console.WriteLine("Zoom: " + threeDEffectiveData.Camera.Zoom);

Extract the effective camera data from the first shape in the first slide. You can customize the slide and shape index based on your specific requirements. Repeat these steps for each slide or shape where you want to fetch camera data.
