public ITable AttributeTable {get; set;}

IRaster2.Colormap Property

The colormap.

Public Property Colormap As IRasterColormap

public IRasterColormap Colormap {get; set;}

IRaster2.CreateCursorEx Method

Creates a cursor with a given pixel block size or native block size.

    ByRef pY As Double _
)

public void PixelToMap (
    int iColumn,
    int iRow,
    ref double pX,
    ref double pY
);

) As Double

public double ToMapX (
    int iColumn
);

IRaster2.ToMapY Method

Maps a pixel row to the y coordinate in map space.

);

Classes that implement IRaster2

Classes	Description
Raster	An in-memory representation of a dynamic raster that can perform resampling and reprojection.

Remarks

IRaster2 interface, new at ArcGIS 9.2, provides many functions working with a Raster object.

• Set geodata transformation on Raster and perform pixel and map transformation.
• Set GeoTransformations (datum transformation) for raster projection.
• Get raster attribute table and raster colormap
• Create raster cursor with a specified pixel block.
