Class J2KImageWriter

java.lang.Object

javax.imageio.ImageWriter

com.sun.media.imageioimpl.plugins.jpeg2000.J2KImageWriter

All Implemented Interfaces:

ImageTranscoder

public class J2KImageWriter
extends ImageWriter

The Java Image IO plugin writer for encoding a RenderedImage into a JPEG 2000 part 1 file (JP2) format. This writer has the capability to (1) Losslessly encode RenderedImages with an IndexColorModel (for example, bi-level or color indexed images). (2) Losslessly or lossy encode RenderedImage with a byte, short, ushort or integer types with band number upto 16384. (3) Encode an image with alpha channel. (4) Write the provided metadata into the code stream. It also can encode a raster wrapped in the provided IIOImage. The encoding process may re-tile image, clip, subsample, and select bands using the parameters specified in the ImageWriteParam.
