Constructor Detail

TIFFImage

public TIFFImage(SeekableStream stream,
                 TIFFDecodeParam param,
                 int directory)
          throws java.io.IOException

Constructs a TIFFImage that acquires its data from a given SeekableStream and reads from a particular IFD of the stream. The index of the first IFD is 0.

Parameters:

stream - the SeekableStream to read from.

param - an instance of TIFFDecodeParam, or null.

directory - the index of the IFD to read from.

Method Detail

getPrivateIFD

public TIFFDirectory getPrivateIFD(long offset)
                            throws java.io.IOException

Reads a private IFD from a given offset in the stream. This method may be used to obtain IFDs that are referenced only by private tag values.

copyData

public java.awt.image.WritableRaster copyData(java.awt.image.WritableRaster wr)

getTile

public java.awt.image.Raster getTile(int tileX,
                                     int tileY)

Returns tile (tileX, tileY) as a Raster.

Overrides:
