XmpThumbnail class

Represents a thumbnail image for a file.

Inheritance: XmpThumbnail → XmpComplexType → XmpMetadataContainer → CustomPackage → MetadataPackage

The XmpThumbnail type exposes the following members:

Constructors

Constructor	Description
`__init__(self)`	Initializes a new instance of the `XmpThumbnail` class.
`__init__(self, width, height)`	Initializes a new instance of the `XmpThumbnail` class.

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.
prefixes	Gets the namespace prefixes that are used in the `XmpComplexType` instance.
namespace_uris	Gets the namespace URIs that are used in the `XmpComplexType` instance.
width	Gets or sets the image width in pixels.
height	Gets or sets the image height in pixels.
image_base64	Gets or sets the full thumbnail image data, converted to base 64 notation.
image_data	Gets the image data.
format	Gets or sets the image format. Defined value: JPEG.

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.
`get_xmp_representation(self)`	Returns string contained value in XMP format.
`get_namespace_uri(self, prefix)`	Gets the namespace URI associated with the specified prefix.
