java.lang.Object
  ucar.jpeg.jj2000.j2k.fileformat.writer.FileFormatWriter

All Implemented Interfaces:

FileFormatBoxes

public class FileFormatWriter
extends Object
implements FileFormatBoxes

This class writes the file format wrapper that may or may not exist around a valid JPEG 2000 codestream. This class writes the simple possible legal fileformat

Constructor Detail

FileFormatWriter

public FileFormatWriter(String filename,
                        int height,
                        int width,
                        int nc,
                        int[] bpc,
                        int clength)

The constructor of the FileFormatWriter. It receives all the information necessary about a codestream to generate a legal JP2 file

Parameters:

filename - The name of the file that is to be made a JP2 file

height - The height of the image

width - The width of the image

nc - The number of components

bpc - The number of bits per component

clength - Length of codestream
