InMemoryOpcPackage

Overview

InMemoryOpcPackage is a class in Aspose.Slides for CPP. Inherits from: InMemoryOpcPackage.

In-memory OPC package with ZIP file I/O support. Manages an Open Packaging Conventions package as an in-memory map of part names to byte arrays. Supports loading from and saving to ZIP archives (file paths or streams), preserving unknown parts for round-trip fidelity.
