Syntax
public class FontObject : Object, IPdfFontObject, IPdfDocumentObject

Use FontObject in IronPDF when a C# application works with Iron Software API. It represents document font object.

FontObject matters when an application needs to configure or invoke Iron Software API from C# code. The class encapsulates the related options and behavior in a single object that is set up once and reused across render or processing calls. Typical scenarios include batch generation pipelines, templated document workflows, and integration with existing C# document services.

To use FontObject, instantiate or obtain it from the relevant entry point in the IronPDF C# API. Key properties include Ascent, BaseFont, BBoxBottom, BBoxLeft. Assign options or invoke methods on the instance to configure or perform the operation.

using IronPdf;

// Obtain FontObject from the relevant entry point in the IronPDF API
void Configure(FontObject instance)
{
    var current = instance.Ascent;
    instance.GetHashCode();
}

For the broader workflow, see the IronPDF C# documentation for related how-to guides and examples. For broader context, the Iron Software API portion of the IronPDF C# API contains related types that work with FontObject directly. FontObject exposes additional members beyond those highlighted above; the reference tables on this page list the full set. In application code, treat FontObject as a configured object that is constructed once and reused across operations rather than instantiated per call. Configuration is generally idempotent: assigning the same property value twice has the same effect as assigning it once. For diagnostic purposes, inspect the relevant FontObject property after each operation to confirm the configured state. See the constructors, properties, and methods tables below for the complete API surface of FontObject. Application code typically obtains or instantiates a single FontObject and shares it across multiple IronPDF operations rather than recreating it per call. For multi-threaded scenarios, follow the threading guidance for the relevant IronPDF entry point; FontObject instances are not assumed to be thread-safe unless documented.
