DngPackage class

Represents native DNG metadata.

Inheritance: DngPackage → CustomPackage → MetadataPackage

The DngPackage type exposes the following members:

Constructor	Description
`__init__(self)`	Initializes a new instance of the `Metadata` class.

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.
camera_manufacturer	Gets the camera manufacturer.
colors_count	Gets the colors.
description	Gets the description of colors (RGBG,RGBE,GMCY, or GBTG).
dng_version	Gets the DNG version.
filters	Gets the Bit mask describing the order of color pixels in the matrix.
is_foveon	Gets the is foveon matrix.
model	Gets the camera model.
raw_count	Gets the number of RAW images in file (0 means that the file has not been recognized).
software	Gets the software.
translation_cfa_dng	Gets the translation array for CFA mosaic DNG format.
aperture	Gets the aperture.
artist	Gets the author of image.
focal_length	Gets the length of the focal.
gps_data	Gets the GPS data.
iso_speed	Gets the ISO sensitivity.
shot_order	Gets serial number of image.
shutter_speed	Gets the shutter speed.
timestamp	Gets the date of shooting.

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.
