Class ObjectStreamMode

Object stream mode used when writing the compressed PDF.

Inheritance

System.Object

ObjectStreamMode

Namespace: IronPdf

Assembly: IronPdf.dll

Syntax

public sealed class ObjectStreamMode : Enum

The ObjectStreamMode enumeration in IronPDF declares how indirect PDF objects are packed when a document is serialised.

Part of the IronPdf namespace, members are Disable, Generate, and Preserve (3 total). AdvancedCompressionOptions exposes the value: Generate minimises file size by bundling objects, Preserve retains the source layout for incremental saves, and Disable produces a flat structure that older readers parse reliably.

See PDF compression for tuning details.
