Provides access to members that control an improved raster workspace.
When To Use
IRasterWorkspace2interface allows to create a raster dataset in addition to the functionalities provided by the IRasterWorkspaceinterface.
Members
| Name | Description | |
|---|---|---|
 |
CanCopy | Indicates if this dataset can be copied. |
|
Copy | Copies this workspace to a new workspace with the specified name. |
|
CreateRasterDataset | Creates a RasterDataset in the workspace given its name. |
|
IsWorkspace | Indicates if the file path specified is a raster workspace. |
|
OpenRasterDataset | Opens a RasterDataset in the workspace given its name. |
IRasterWorkspace2.CanCopy Method
Indicates if this dataset can be copied.
Public Function CanCopy ( _
) As Boolean
public bool CanCopy (
);
IRasterWorkspace2.Copy Method
Copies this workspace to a new workspace with the specified name.
Public Function Copy ( _
ByVal copyName As String, _
ByVal copyWorkspace As IWorkspace _
) As IDataset
public IDataset Copy (
string copyName,
IWorkspace copyWorkspace
);
Remarks
Not implemented.
IRasterWorkspace2.CreateRasterDataset Method
Creates a RasterDataset in the workspace given its name.
Public Function CreateRasterDataset ( _
ByVal Name As String, _
ByVal Format As String, _
ByVal Origin As IPoint, _
ByVal columnCount As Integer, _
ByVal RowCount As Integer, _
ByVal cellSizeX As Double, _
ByVal cellSizeY As Double, _
ByVal numBands As Integer, _
ByVal PixelType As rstPixelType, _
[ByVal SpatialReference As ISpatialReference], _
[ByVal Permanent As Boolean] _
) As IRasterDataset
public IRasterDataset CreateRasterDataset (
string Name,
string Format,
IPoint Origin,
int columnCount,
int RowCount,
double cellSizeX,
double cellSizeY,
int numBands,
rstPixelType PixelType,
ISpatialReference SpatialReference,
bool Permanent
);
Remarks
_CreateRasterDataset_creates a file based raster dataset, the origin, width, and height of the raster dataset must be specified along with other required parameters, the raster dataset with the specified dimension and default pixel values will be created . The default pixel values of the raster dataset can be modified by writting pixel blocks to the dataset or mosaicking.
CreateRasterDataset can be used to create GRID, TIFF, ERDAS Imagine,BMP, Idrisi format, and in memory raster. The strings used to specify formats are "GRID", "TIFF", "IMAGINE Image", "BMP", "RST", and "MEM" respectively. The strings are case-sensitive.
For GRID format, _CreateRasterDataset_only allows square cell size.
When creating an in memory raster, the file name can be an empty string.
IRasterWorkspace2.IsWorkspace Method
Indicates if the file path specified is a raster workspace.
Public Function IsWorkspace ( _
ByVal Name As String _
) As Boolean
public bool IsWorkspace (
string Name
);
IRasterWorkspace2.OpenRasterDataset Method
Opens a RasterDataset in the workspace given its name.
Public Function OpenRasterDataset ( _
ByVal Name As String _
) As IRasterDataset
public IRasterDataset OpenRasterDataset (
string Name
);
Remarks
OpenRasterDataset opens a RasterDataset from a supported file based raster format, such as GRID, Imagine, BMP, TIFF, etc.
Classes that implement IRasterWorkspace2
| Classes | Description |
|---|---|
| RasterWorkspace (esriDataSourcesRaster) | The raster workspace object. |
Remarks
IRasterWorspace2 is used to access a raster stored in a file system in any supported raster format. To access raster from geodtabase, use IRasterWorkspaceEx interface.
