Constructor Detail

TIFFImage

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

Throws:

IOException

Method Detail

getPrivateIFD

public TIFFDirectory getPrivateIFD(long offset)
                            throws 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.

Throws:

IOException

copyData

public WritableRaster copyData(WritableRaster wr)

getTile

public Raster getTile(int tileX,
                      int tileY)

Returns tile (tileX, tileY) as a Raster.

Specified by:

getTile in interface RenderedImage

Overrides:

getTile in class AbstractRed
