Class RawImageWriter

java.lang.Object

javax.imageio.ImageWriter

com.sun.media.imageioimpl.plugins.raw.RawImageWriter

All Implemented Interfaces:

ImageTranscoder

public class RawImageWriter
extends ImageWriter

The Java Image IO plugin writer for encoding a binary RenderedImage into a Raw format.

The encoding process may clip, subsample or select bands using the parameters specified in the ImageWriteParam. Thus, when read this raw image the proper image data type should be provided.
