It has the capability to load the compressed bilevel images, color-indexed byte images, or multi-band images in byte/ushort/short/int data type. It may subsample the image, select bands, clip the image, and shift the decoded image origin if the proper decoding parameter are set in the provided J2KImageReadParam.

Method Summary public  boolean canReadRaster()      public static  void checkReadParamBandSettingsWrapper(ImageReadParam param, int numSrcBands, int numDstBands)      Wrapper for the protected method checkReadParamBandSettings. public static  void computeRegionsWrapper(ImageReadParam param, boolean allowZeroDestOffset, int srcWidth, int srcHeight, BufferedImage image, Rectangle srcRegion, Rectangle destRegion)      Wrapper for the protected method computeRegions. public  void flush()      public  boolean getAbortRequest()      This method wraps the protected method abortRequested to allow the abortions be monitored by J2KReadState. public  ImageReadParam getDefaultReadParam()      public  int getHeight(int imageIndex)      public  IIOMetadata getImageMetadata(int imageIndex)      public  Iterator getImageTypes(int imageIndex)      public  int getNumImages(boolean allowSearch)      Overrides the method defined in the superclass. static  Rectangle getReducedRect(Rectangle r, int maxLevel, int level, int subX, int subY)      Convert a rectangle provided in the coordinate system of the JPEG2000 reference grid to coordinates at a lower resolution level where zero denotes the lowest resolution level. Parameters:   r - A rectangle in references grid coordinates. Parameters:   maxLevel - The highest resolution level in the image. Parameters:   level - The resolution level of the returned rectangle. Parameters:   subX - The horizontal subsampling step size.

So it can be access from the classes which are not in ImageReader hierarchy. flush public void flush()(Code) getAbortRequest public boolean getAbortRequest()(Code) This method wraps the protected method abortRequested to allow the abortions be monitored by J2KReadState. getDefaultReadParam public ImageReadParam getDefaultReadParam()(Code) getHeight public int getHeight(int imageIndex) throws IOException(Code) getImageMetadata public IIOMetadata getImageMetadata(int imageIndex) throws IOException(Code) getImageTypes public Iterator getImageTypes(int imageIndex) throws IOException(Code) getNumImages public int getNumImages(boolean allowSearch) throws IOException(Code) Overrides the method defined in the superclass. getReducedRect static Rectangle getReducedRect(Rectangle r, int maxLevel, int level, int subX, int subY)(Code) Convert a rectangle provided in the coordinate system of the JPEG2000 reference grid to coordinates at a lower resolution level where zero denotes the lowest resolution level. Parameters:   r - A rectangle in references grid coordinates. Parameters:   maxLevel - The highest resolution level in the image. Parameters:   level - The resolution level of the returned rectangle. Parameters:   subX - The horizontal subsampling step size. Parameters:   subY - The vertical subsampling step size. The parameter rectangle converted to a lower resolution level. throws:   IllegalArgumentException - if r is null,maxLevel or level is negative, orlevel is greater than maxLevel. getStreamMetadata public IIOMetadata getStreamMetadata() throws IOException(Code) getTileGridXOffset public int getTileGridXOffset(int imageIndex) throws IOException(Code) getTileGridYOffset public int getTileGridYOffset(int imageIndex) throws IOException(Code) getTileHeight public int getTileHeight(int imageIndex) throws IOException(Code) getTileWidth public int getTileWidth(int imageIndex) throws IOException(Code) getWidth public int getWidth(int imageIndex) throws IOException(Code) isImageTiled public boolean isImageTiled(int imageIndex)(Code) isRandomAccessEasy public boolean isRandomAccessEasy(int imageIndex) throws IOException(Code) println public void println(String str, int flind, int ind)(Code) printmsg public void printmsg(int sev, String msg)(Code) processImageProgressWrapper public void processImageProgressWrapper(float percentageDone)(Code) Wrapper for the protected method processImageProgress So it can be access from the classes which are not in ImageReader hierarchy. processImageUpdateWrapper public void processImageUpdateWrapper(BufferedImage theImage, int minX, int minY, int width, int height, int periodX, int periodY, int[] bands)(Code) Wrapper for the protected method processImageUpdate So it can be access from the classes which are not in ImageReader hierarchy. read public BufferedImage read(int imageIndex, ImageReadParam param) throws IOException(Code) readAsRenderedImage public RenderedImage readAsRenderedImage(int imageIndex, ImageReadParam param) throws IOException(Code) readHeader public void readHeader()(Code) readRaster public Raster readRaster(int imageIndex, ImageReadParam param) throws IOException(Code) reset public void reset()(Code) setInput public void setInput(Object input, boolean seekForwardOnly, boolean ignoreMetadata)(Code) Overrides the method defined in the superclass.
