Get PDF Properties

In this tutorial, we’ll walk you through the step-by-step process to get the properties of a PDF using Aspose.PDF for .NET. We’ll explain the bundled C# source code and provide you with a comprehensive guide to help you understand and implement this feature in your own projects. At the end of this tutorial, you will know how to access different properties of a PDF page such as art box, crop box, crop box, etc., using Aspose.PDF for .NET.

Prerequisites

Before you begin, make sure you have the following:

  • A basic knowledge of the C# programming language
  • Aspose.PDF for .NET installed in your development environment

Step 1: Set document directory

First, you need to set the path to your documents directory. This is the location of the PDF file whose properties you want to get. Replace “YOUR DOCUMENTS DIRECTORY” with the appropriate path.

string dataDir = "YOUR DOCUMENTS DIRECTORY";

Step 2: Open the PDF document

Next, you need to open the PDF document using the Document class of Aspose.PDF. Be sure to specify the correct path to the PDF file.

Document pdfDocument = new Document(dataDir + "GetProperties.pdf");

Step 3: Access the Page Collection

Now you can access the document’s pages collection using the Pages property of the pdfDocument object.

PageCollection pageCollection = pdfDocument.Pages;

Step 4: Go to a specific page

Then you can jump to a specific page using the index of the page in the collection. In the example below, we access the second page (index 1).

Page pdfPage = pageCollection[1];

Step 5: Get page properties

Now you can get the different properties of the PDF page, such as art box, crop box, crop box, etc., by using the corresponding properties of the pdfPage object.

Console.WriteLine("ArtBox: Height={0}, Width={1}, LLX={2}, LLY={3}, URX={4}, URY={5}", pdfPage.ArtBox.Height, pdfPage.ArtBox.Width, pdfPage.ArtBox.LLX, pdfPage.ArtBox.LLY, pdfPage.ArtBox.URX, pdfPage.ArtBox.URY);
Console.WriteLine("BleedBox: Height={0}, Width={1}, LLX={2}, LLY={3}, URX={4}, URY={5}", pdfPage.BleedBox.Height, pdf

Page.BleedBox.Width, pdfPage.BleedBox.LLX, pdfPage.BleedBox.LLY, pdfPage.BleedBox.URX, pdfPage.BleedBox.URY);
Console.WriteLine("CropBox: Height={0}, Width={1}, LLX={2}, LLY={3}, URX={4}, URY={5}", pdfPage.CropBox.Height, pdfPage.CropBox.Width, pdfPage.CropBox.LLX, pdfPage.CropBox.LLY, pdfPage.CropBox.URX, pdfPage.CropBox.URY);
Console.WriteLine("MediaBox: Height={0}, Width={1}, LLX={2}, LLY={3}, URX={4}, URY={5}", pdfPage.MediaBox.Height, pdfPage.MediaBox.Width, pdfPage.MediaBox.LLX, pdfPage.MediaBox.LLY, pdfPage.MediaBox.URX, pdfPage.MediaBox.URY);
Console.WriteLine("TrimBox: Height={0}, Width={1}, LLX={2}, LLY={3}, URX={4}, URY={5}", pdfPage.TrimBox.Height, pdfPage.TrimBox.Width, pdfPage.TrimBox.LLX, pdfPage.TrimBox.LLY, pdfPage.TrimBox.URX, pdfPage.TrimBox.URY);
Console.WriteLine("Rect: Height={0}, Width={1}, LLX={2}, LLY={3}, URX={4}, URY={5}", pdfPage.Rect.Height, pdfPage.Rect.Width, pdfPage.Rect.LLX, pdfPage.Rect.LLY, pdfPage.Rect.URX, pdfPage.Rect.URY);
Console.WriteLine("Page number: {0}", pdfPage.Number);
Console.WriteLine("Rotate: {0}", pdfPage.Rotate);
