IRasterDatasetJukebox Interface

Provides access to members that control subdatasets.

Members

	Name	Description
	Subdataset	The current active subdataset.
	SubdatasetCount	The number of subdatasets.
	SubdatasetDescription	The given subdataset description.
	SubdatasetName	The given subdataset name.

IRasterDatasetJukebox.Subdataset Property

The current active subdataset.

Public Property Subdataset As Integer

public int Subdataset {get; set;}

Remarks

This property is used to get/set the index of a subdataset which becomes the current raster dataset

IRasterDatasetJukebox.SubdatasetCount Property

The number of subdatasets.

Public ReadOnly Property SubdatasetCount As Integer

public int SubdatasetCount {get;}

IRasterDatasetJukebox.SubdatasetDescription Property

The given subdataset description.

Public Function get_SubdatasetDescription ( _
    ByVal SubdatasetID As Integer _
) As String

public string get_SubdatasetDescription (
    int SubdatasetID
);

IRasterDatasetJukebox.SubdatasetName Property

The given subdataset name.

Public Function get_SubdatasetName ( _
    ByVal SubdatasetID As Integer _
) As String

public string get_SubdatasetName (
    int SubdatasetID
);

Remarks

The subdataset name has the following form: HDF4_SDS:subdataset_type:file_name:subdataset_index

where subdataset_type shows predefined names for some of the well known HDF datasets, file_name is the name of the input file, and subdataset_index is the index of the image to use.

Classes that implement IRasterDatasetJukebox

Classes	Description
RasterDataset	A representation of a raster dataset on disk.

Remarks

Some raster formats can contain multiple subdatasets inside a single file, for example the HDF format. The IRasterDatasetJukebox interface is used to query the number of subdatasets, their names, and the descriptions inside the file and retrive subdatasets, one at a time.
