The Raster Value Class.
Product Availability
Description
The RasterValue represents the value of a Raster field, similar to the value of a Geometry field. A RasterValue consists a RasterDataset and its storage properties specified by RasterStorageDef, including tile size, pyramid definition, compression, cellsize and origin. A RasterVaue in an ArcSDE geodatabase consists of a database RasterDataset, while a RasterValue in a personal geodatabase consists a file based RasterDataset.
The RasterValue object is used to set or update a Raster field with a given Raser, RasterDataset or RasterDatasetName. It works the same way for Personal, File and ArcSDE geodatabases, except for a RasterValue stored in a Personal geodatabase since most of the storage properties (tilesize, compression options and pyramids options) are ignored.
