Method Detail

createDirectory

public XTIFFDirectory createDirectory(com.sun.media.jai.codec.SeekableStream stream,
                                      int directory)
                               throws IOException

Constructs a TIFFDirectoryFactory from a SeekableStream. The directory parameter specifies which directory to read from the linked list present in the stream; directory 0 is normally read but it is possible to store multiple images in a single TIFF file by maintaing multiple directories.

Overrides:

createDirectory in class XTIFFFactory

Parameters:

stream - a SeekableStream to read from.

directory - the index of the directory to read.

Throws:

IOException

createDirectory

public XTIFFDirectory createDirectory(com.sun.media.jai.codec.SeekableStream stream,
                                      long ifd_offset)
                               throws IOException

Constructs a TIFFDirectory by reading a SeekableStream. The ifd_offset parameter specifies the stream offset from which to begin reading; this mechanism is sometimes used to store private IFDs within a TIFF file that are not part of the normal sequence of IFDs.

Overrides:

createDirectory in class XTIFFFactory

Parameters:

stream - a SeekableStream to read from.

ifd_offset - the long byte offset of the directory.

Throws:

IOException

createDirectory

public XTIFFDirectory createDirectory()

Constructs an empty TIFFDirectory for writing

Overrides:

createDirectory in class XTIFFFactory
