IRasterCalcUniqueValues Interface

Provides access to members that controls calculation of unique values.

Members

	Name	Description
	AddFromRaster	Adds values from a given band of a Raster.
	AddFromRasterAsDecimal	Adds decimal values truncated to a given precision from a given band of a Raster.
	AddFromTable	Adds values of a field of a table.

IRasterCalcUniqueValues.AddFromRaster Method

Adds values from a given band of a Raster.

Public Sub AddFromRaster ( _
    ByVal pRaster As IRaster, _
    ByVal iBand As Integer, _
    ByVal pUniqueValues As IUniqueValues _
)

public void AddFromRaster (
    IRaster pRaster,
    int iBand,
    IUniqueValues pUniqueValues
);

IRasterCalcUniqueValues.AddFromRasterAsDecimal Method

Adds decimal values truncated to a given precision from a given band of a Raster.

Public Sub AddFromRasterAsDecimal ( _
    ByVal pRaster As IRaster, _
    ByVal iBand As Integer, _
    ByVal precision As Double, _
    ByVal pUniqueValues As IUniqueValues _
)

public void AddFromRasterAsDecimal (
    IRaster pRaster,
    int iBand,
    double precision,
    IUniqueValues pUniqueValues
);

IRasterCalcUniqueValues.AddFromTable Method

Adds values of a field of a table.

Public Sub AddFromTable ( _
    ByVal pCursor As ICursor, _
    ByVal iValueField As Integer, _
    ByVal iCountField As Integer, _
    ByVal pUniqueValues As IUniqueValues _
)

public void AddFromTable (
    ICursor pCursor,
    int iValueField,
    int iCountField,
    IUniqueValues pUniqueValues
);

Classes that implement IRasterCalcUniqueValues

Classes	Description
RasterCalcUniqueValues	A helper class for calculating raster unique values.

Remarks

The two methods operate on the input UniqueValues object and accumulate new unique values to it. So you must co-create the UniqueValues object before calling the two methods.
