Constructor Detail

XTIFFImage

public XTIFFImage(com.sun.media.jai.codec.SeekableStream stream,
          com.sun.media.jai.codec.TIFFDecodeParam param,
          int directory)
           throws java.io.IOException

Constructs a XTIFFImage 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:

java.io.IOException

Method Detail

setupImageParameters

protected void setupImageParameters()

This method gets the image parameters from fields

setupSamplesAndColor

protected void setupSamplesAndColor()

This method constructs the sampleModel, colorModel, determines the image_type and the bands parameter.

getPrivateIFD

public XTIFFDirectory 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.

Throws:

java.io.IOException

getTile

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

Returns tile (tileX, tileY) as a Raster.
