PdfPackage class

Represents native metadata in a PDF document.

Inheritance: PdfPackage → DocumentPackage → CustomPackage → MetadataPackage

The PdfPackage type exposes the following members:

Properties

Property	Description
metadata_type	Gets the metadata type.
keys	Gets a collection of the metadata property names.
property_descriptors	Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.
count	Gets the number of metadata properties.
author	Gets or sets the document author.
created_date	Gets or sets the date of document creation.
creator	Gets the creator of the document.
keywords	Gets or sets the keywords.
modified_date	Gets or sets the date of the last modification.
producer	Gets the document producer.
subject	Gets or sets the subject of the document.
title	Gets or sets the title of the document.
trapped_flag	Gets or sets the trapped flag.

Methods

Method	Description
`contains(self, property_name)`	Determines whether the package contains a metadata property with the specified name.
`find_properties(self, specification)`	Finds the metadata properties satisfying a specification. The search is recursive so it affects all nested packages as well.
`update_properties(self, specification, value)`	Updates known metadata properties satisfying a specification. The operation is recursive so it affects all nested packages as well.
`remove_properties(self, specification)`	Removes metadata properties satisfying a specification.
`add_properties(self, specification, value)`	Adds known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well.
`set_properties(self, specification, value)`	Sets known metadata properties satisfying the specification. The operation is recursive so it affects all nested packages as well. This method is a combination of `MetadataPackage.add_properties` and `MetadataPackage.update_properties`. If an existing property satisfies the specification its value is updated. If there is a known property missing in the package that satisfies the specification it is added to the package.
`sanitize(self)`	Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
`remove(self, property_name)`	Removes a writable metadata property by the specified name.
`clear(self)`	Removes all writable metadata properties from the package.
`clear_built_in_properties(self)`	Removes all built-in metadata properties.
`clear_custom_properties(self)`	Removes all custom metadata properties.
`set(self, property_name, value)`	Adds or replaces the metadata property with the specified name.
