Create Multilayer PDF File First Approach

In this tutorial, we will guide you through the process of creating a multilayer PDF file using the first approach with Aspose.PDF for .NET. This approach allows you to add multiple layers to your PDF file. Follow the step-by-step guide below:

Step 1: Initialize the PDF document

string dataDir = "YOUR DOCUMENT DIRECTORY";
Aspose.Pdf.Document pdf = new Aspose.Pdf.Document();

Step 2: Add a new page to the document

Aspose.Pdf.Page sec1 = pdf.Pages.Add();

Step 3: Add a text fragment to the page

Aspose.Pdf.Text.TextFragment t1 = new Aspose.Pdf.Text.TextFragment("paragraph 3 segment");
sec1.Paragraphs.Add(t1);

Step 4: Customize the text fragment

t1.Text = "paragraph 3 segment 1";
t1.TextState.ForegroundColor = Color.Red;
t1.TextState.FontSize = 12;

Step 5: Add an image to the page

Aspose.Pdf.Image image1 = new Aspose.Pdf.Image();
image1.File = dataDir + "test_image.png";

Step 6: Add a floating box to the page

Aspose.Pdf.FloatingBox box1 = new Aspose.Pdf.FloatingBox(117, 21);
sec1.Paragraphs.Add(box1);

box1.Left = -4;
box1.Top = -4;
box1.Paragraphs.Add(image1);

Step 7: Save the resultant PDF document

pdf.Save(dataDir + "CreateMultiLayerPdf_out.pdf");

Congratulations! You have successfully created a multilayer PDF document using the first approach with Aspose.PDF for .NET.

sec1.Paragraphs.Add(t1);

t1.Text = "paragraph 3 segment 1";
t1.TextState.ForegroundColor = Color.Red;
t1.TextState.FontSize = 12;

Aspose.Pdf.Image image1 = new Aspose.Pdf.Image();
image1.File = dataDir + "test_image.png";

Aspose.Pdf.FloatingBox box1 = new Aspose.Pdf.FloatingBox(117, 21);
sec1.Paragraphs.Add(box1);

box1.Left = -4;
box1.Top = -4;
box1.Paragraphs.Add(image1);

pdf.Save(dataDir + "CreateMultiLayerPdf_out.pdf");
