IRasterCatalogTable Interface

Provides access to members that control a raster catalog table.

Description

A raster catalog is a table in any supported table format (including INFO, dbf, access, text, and others) that contains a list of raster datasets and their geographic extents.

The first five columns of the table must be called "Image", "Xmin", "Ymin", "Xmax", and "YMax" for the table to be identified as a raster catalog. The first column contains the path to a dataset on disk, while the next four contain the bounding box of the dataset. Additional fields in the table are allowed but will have no effect on the display of the raster catalog.

Members

	Name	Description
	FieldBoundsLocation	Bounds of the field location of the raster catalog.
	FieldNameLocation	Location of the field name of the raster catalog.
	OID	OID of the ith raster in the raster catalog.
	RasterDataset	Reference to the ith raster dataset in the raster catalog.
	RasterExtent	Extent of the ith raster in the catalog.
	RasterName	Name of the ith raster in the raster catalog.
	Size	Number of rasters in the raster catalog.
	Table	The table object underlying the raster catalog table.
	Update	Updates the object after the table is changed.
	WhereClause	A SQL expression limiting the list of rasters currently viewed.

IRasterCatalogTable.FieldBoundsLocation Property

Bounds of the field location of the raster catalog.

Public Sub FieldBoundsLocation ( _
    ByRef pLocXmin As Integer, _
    ByRef pLocYmin As Integer, _
    ByRef pLocXmax As Integer, _
    ByRef pLocYMax As Integer _
)

public void FieldBoundsLocation (
    ref int pLocXmin,
    ref int pLocYmin,
    ref int pLocXmax,
    ref int pLocYMax
);

IRasterCatalogTable.FieldNameLocation Property

Location of the field name of the raster catalog.

Public ReadOnly Property FieldNameLocation As Integer

public int FieldNameLocation {get;}

IRasterCatalogTable.OID Property

OID of the ith raster in the raster catalog.

Public Function get_OID ( _
    ByVal idx As Integer _
) As Integer

public int get_OID (
    int idx
);

IRasterCatalogTable.RasterDataset Property

Reference to the ith raster dataset in the raster catalog.

Public Function get_RasterDataset ( _
    ByVal idx As Integer _
) As IRasterDataset

public IRasterDataset get_RasterDataset (
    int idx
);

Remarks

RasterCatalogTable created from raster catalog in file system and in the geodatabase has slightly different OIDs. The first starts from 0 and the later one starts from 1. To ensure your program work properly for both cases, pass OID, which can be obtained from IRasterCatalogTable::OID(index) to this property, instead of passing index directly.

IRasterCatalogTable.RasterExtent Property

Extent of the ith raster in the catalog.

Public Function get_RasterExtent ( _
    ByVal idx As Integer _
) As IEnvelope

public IEnvelope get_RasterExtent (
    int idx
);

Remarks

RasterCatalogTable created from raster catalog in file system and in the geodatabase has slightly different OIDs. The first starts from 0 and the later one starts from 1. To ensure your program work properly for both cases, pass OID, which can be obtained from IRasterCatalogTable::OID(index) to this property, instead of passing index directly.

IRasterCatalogTable.RasterName Property

Name of the ith raster in the raster catalog.

Public Function get_RasterName ( _
    ByVal idx As Integer _
) As String

public string get_RasterName (
    int idx
);

Remarks

RasterCatalogTable created from raster catalog in file system and in the geodatabase has slightly different OIDs. The first starts from 0 and the later one starts from 1. To ensure your program work properly for both cases, pass OID, which can be obtained from IRasterCatalogTable::OID(index) to this property, instead of passing index directly.

IRasterCatalogTable.Size Property

Number of rasters in the raster catalog.

Public ReadOnly Property Size As Integer

public int Size {get;}

IRasterCatalogTable.Table Property

The table object underlying the raster catalog table.

Public Property Table As ITable

public ITable Table {get; set;}

IRasterCatalogTable.Update Method

Updates the object after the table is changed.

Public Sub Update ( _
)

public void Update (
);

IRasterCatalogTable.WhereClause Property

A SQL expression limiting the list of rasters currently viewed.

Public Property WhereClause As String

public string WhereClause {get; set;}

Classes that implement IRasterCatalogTable

Classes	Description
RasterCatalogTable	A special type of table used to display multiple rasters simultaneously.
SdeRasterCatalogTable	A class for managing 8.x ArcSDE RasterCatalogs.

Remarks

The IRasterCatalogTableobject allows you to access information about a raster catalog including the extent and name for each dataset in the catalog and the number of datasets (Siz_e) and _Extent of the entire raster catalog.

You can also provide a table in the correct format to be used as the RasterCatalogTabl**e (The counterpart for 8.x tyle ArcSDE raster catalog is SdeRasterCatalogTable). You must call the _Update_ method after putting a table in the RasterCatalogTabl**e.
