using Aspose.ThreeD.Formats;

Loading and Saving - Opening Scene from Protected PDF

Step 1: Create a new scene

To kick things off, initialize a new scene using the following code snippet:

// ExStart:OpenSceneFromProtectedPdf
// Create a new scene
Scene scene = new Scene();
// ExEnd:OpenSceneFromProtectedPdf

Step 2: Loading options and applying password

Now, set up loading options and apply the password for the protected PDF. This ensures secure access to the PDF file:

// ExStart:OpenSceneFromProtectedPdf
PdfLoadOptions opt = new PdfLoadOptions() { Password = Encoding.UTF8.GetBytes("password") };
// ExEnd:OpenSceneFromProtectedPdf

Step 3: Open the scene from the PDF file

Use the loaded options to open the scene from the protected PDF:

// ExStart:OpenSceneFromProtectedPdf
scene.Open(RunExamples.GetDataFilePath("House_Design.pdf"), opt);
// ExEnd:OpenSceneFromProtectedPdf

By following these steps, you’ve successfully loaded a 3D scene from a protected PDF using Aspose.3D for .NET.
