What implements IPdfPage in IronPDF?

Concrete implementors of IPdfPage in IronPDF include PdfPage. Code that accepts IPdfPage works uniformly across all implementors, with a cast to the concrete type only required when type-specific behavior is needed.

How do you use IPdfPage in C# code?

Accept IPdfPage as a parameter or return type in C# code that needs to work uniformly across IronPDF implementors. The interface defines the contract; concrete behavior is provided by the implementor returned at runtime.

What is the difference between IPdfPage and a concrete implementor?

IPdfPage is the interface contract; its concrete implementors carry the actual behavior. Reference IPdfPage when writing code that should work across multiple implementors; use a concrete type when a single implementor's behavior is required.

Where is IPdfPage located in the IronPDF object model?

IPdfPage is in the IronPdf.Pages namespace, shipped in IronPdf.dll. It extends IDocumentPage . Concrete classes such as PdfPage implement it.

Interface IPdfPage

PDF document page interface

Namespace: IronPdf.Pages

Assembly: IronPdf.dll

Syntax

public interface IPdfPage

Working with PDF pages through a shared contract runs through IPdfPage. It represents PDF document page interface, so code can work with PDF pages uniformly across implementors rather than binding to a concrete type.

Concrete implementors include PdfPage, IronPDF concrete implementor. Code that accepts IPdfPage works uniformly across these implementors, so applications can read or configure C# PDF features without binding to a specific concrete type.

Most of the usable surface is inherited. The members that carry everyday use of this contract are Characters, Lines, PageRotation, PrintHeight; consult these first when implementing or consuming IPdfPage.

using IronPdf;

// IPdfPage is consumed as the API surface for the family of implementors
void Consume(IPdfPage target)
{
    // Use members defined on the interface; concrete behavior follows the implementor
}

For collection-wide operations and end-to-end examples, see the IronPDF C# documentation for related guides. For collection-wide operations on IPdfPage instances, the IronPDF C# documentation lists the relevant container types and their methods. Concrete behavior depends on which implementor of IPdfPage is returned at runtime; consult the specific class reference for type-specific members. Polymorphic access through IPdfPage lets code work uniformly across the family of implementors, with a cast required only when type-specific behavior is needed. The reference tables below list the full set of members defined on IPdfPage along with any inherited members exposed through the contract. In a typical IronPDF C# workflow, IPdfPage appears as a parameter or return type at the boundary between the application and the IronPDF API. See the methods table below for the complete set of members defined directly on IPdfPage. Implementing IPdfPage directly in application code is uncommon; the typical pattern is to consume instances returned from the IronPDF API. When iterating over a collection of IPdfPage instances, prefer the inherited members for portable code; downcast only when type-specific behavior is required.
