 CLSID // gets or sets the guid structure, which contains the guid that can recognize a specific decoder. Formatid // obtain or set the guid structure, which contains the guid used to identify the decoder format. Codecname // obtain or set a string containing the decoder name. Dllname // obtain or set the path name string containing the DLL that stores the decoder. If the decoder is not in the DLL, the pointer is null. Formatdescription // gets or sets a string that describes the file format of the decoder. Filenameextension // gets or sets a string that contains the file extension used in the decoder. These extensions are separated by semicolons. Mimetype // gets or sets a multi-purpose Internet Mail extended protocol (MIME) string containing the decoder. Flags // gets or sets the 32-bit value used to store other information about the decoder. This attribute returns a combination of several flags from the imagecodecflags enumeration. Version // obtain or set the version number of the decoder. Sigmask // gets or sets a two-dimensional byte array that can be used as a filter. Sigpattern // obtain or set a two-dimensional byte array that represents the decoder signature.
