What are XMP annotations?

XMP

XMP annotations are XML-based objects specifically designed in Nutrient SDKs to enrich and enhance the PDF annotation functionality.

Apart from the standard PDF annotation functionality, our dedicated AnnotationManager class enables you to add annotations not only to PDF documents, but also to images and TIFF files. The XMP annotations can also be saved to a separate XML file that’s independent from the source file. This makes it possible to apply different annotations to multiple files.

For a detailed description of how to use XMP annotations, refer to the XMP annotations guide.
