| Namespace | Description |
| --- | --- |
| [Aspose::Pdf](./aspose.pdf/) | The **[Aspose.Pdf](./aspose.pdf/)** is a root namespace for all classes of [Aspose.Pdf](./aspose.pdf/) library which are either directly in it like **[Document](./aspose.pdf/document/)** or indirectly through several subnamespaces. |
| [Aspose::Pdf::Annotations](./aspose.pdf.annotations/) | The **[Aspose.Pdf.Annotations](./aspose.pdf.annotations/)** namespace provides classes for working with various types of actions, destinations and other features of document which traditionally called as interactive providing means user can intercommunicate with it. |
| [Aspose::Pdf::Collections](./aspose.pdf.collections/) |  |
| [Aspose::Pdf::Comparison](./aspose.pdf.comparison/) | The **[Aspose.Pdf.Comparison](./aspose.pdf.comparison/)** namespace provides classes for the PDF comparison functionalities. |
| [Aspose::Pdf::DataEditor](./aspose.pdf.dataeditor/) | The **[Aspose.Pdf.DataEditor](./aspose.pdf.dataeditor/)** contains tools for editing data within a document. |
| [Aspose::Pdf::Devices](./aspose.pdf.devices/) | The **[Aspose.Pdf.Devices](./aspose.pdf.devices/)** namespace provides classes which are used for representing document as image(s) or a plain text.
