How to Access All PDF DOM Objects

by Chaknith Bin

Accessing the PDF DOM object refers to interacting with the structure of a PDF file in a way similar to manipulating a webpage's DOM (Document Object Model). In the context of PDFs, the DOM is a representation of the document’s internal structure, allowing developers to access and manipulate different elements such as text, images, annotations, and metadata programmatically.

Access DOM Objects Example

The ObjectModel can be accessed from the PdfPage object. First, import the target PDF and access its Pages property. From there, select any page, and you will have access to the ObjectModel property.

:path=/static-assets/pdf/content-code-examples/how-to/access-pdf-dom-object.cs

using IronPdf;
using System.Linq;

// Instantiate Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Create a PDF from a URL
PdfDocument pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/");

// Access DOM Objects
var objects = pdf.Pages.First().ObjectModel;

Imports IronPdf
Imports System.Linq

' Instantiate Renderer
Private renderer As New ChromePdfRenderer()

' Create a PDF from a URL
Private pdf As PdfDocument = renderer.RenderUrlAsPdf("https://ironpdf.com/")

' Access DOM Objects
Private objects = pdf.Pages.First().ObjectModel

The ObjectModel property currently consists of ImageObject, PathObject, and TextObject. Each object contains information about the page index it is on, its bounding box, scale, and translation. This information can also be modified.

ImageObject:

• Height: Height of the image.
• Width: Width of the image.
• ExportBytesAsJpg: A method to export the image as a byte array in JPG format.

PathObject:

• FillColor: The fill color of the path.
• StrokeColor: The stroke color of the path.
• Points: A collection of points defining the path.

TextObject:

• Color: The color of the text.
• Contents: The actual text content.
