Package oracle.spatial.georaster.image

Provides support for generating Java images from a GeoRaster object or a subset of a GeoRaster object, and for processing the images. It is the rendering engine for displaying GeoRaster objects. This package depends upon and leverages JAI.

Class Summary

Class	Description
GeoRasterImage	GeoRasterImage is a GeoRaster image engine, which is used to generate Java images from a GeoRaster object or a subset of a GeoRaster object based on the metadata of the GeoRaster object and different query conditions.
GeoRasterImage.NodataMapping
GeoRasterImageProcessUtil	The GeoRasterImageProcessUtil class provides the following basic image processing functions:
RasterImage	RasterImage is a Java class that generates a RenderedImage object from a Blob or a byte array. There are two constructors which take data in byte[] or Blob: public RasterImage( byte[] data, long height, long width, long nbands, String cellDepth, String interleaving) throws GeoRasterException; public RasterImage( Blob blob, long height, long width, long nbands, String cellDepth, String interleaving) throws GeoRasterException, SQLException; If nbands is 1 or 3 and nodataMapping has transparent=true this class will add an alpha band to apply nodataMapping transparent values. If setHasAlpha(true) is invoked and nbands is 2 or 4, the last band will be interpreted has alpha band. Example on how to use the class:
