Class ImageEncoderImpl

public abstract class ImageEncoderImpl extends Object implements ImageEncoder

A partial implementation of the ImageEncoder interface useful for subclassing.

This class is not a committed part of the JAI API. It may be removed or changed in future releases of JAI.

Field Summary
protected OutputStream	output The OutputStream associcted with this ImageEncoder.
protected ImageEncodeParam	param The ImageEncodeParam object associcted with this ImageEncoder.

Constructor Summary
	ImageEncoderImpl(OutputStream output, ImageEncodeParam param) Constructs an ImageEncoderImpl with a given OutputStream and ImageEncoderParam instance.

Method Summary
void	encode(Raster ras, ColorModel cm) Encodes a Raster with a given ColorModel and writes the output to the OutputStream associated with this ImageEncoder.
abstract void	encode(RenderedImage im) Encodes a RenderedImage and writes the output to the OutputStream associated with this ImageEncoder.
OutputStream	getOutputStream() Returns the OutputStream associated with this ImageEncoder.
ImageEncodeParam	getParam() Returns the current parameters as an instance of the ImageEncodeParam interface.
void	setParam(ImageEncodeParam param) Sets the current parameters to an instance of the ImageEncodeParam interface.

Field Detail

output

protected OutputStream output

The OutputStream associcted with this ImageEncoder.

param

protected ImageEncodeParam param

The ImageEncodeParam object associcted with this ImageEncoder.

Constructor Detail

ImageEncoderImpl

public ImageEncoderImpl(OutputStream output, ImageEncodeParam param)

Constructs an ImageEncoderImpl with a given OutputStream and ImageEncoderParam instance.

Method Detail

encode

public void encode(Raster ras, ColorModel cm)

Encodes a Raster with a given ColorModel and writes the output to the OutputStream associated with this ImageEncoder.

encode

public abstract void encode(RenderedImage im)

Encodes a RenderedImage and writes the output to the OutputStream associated with this ImageEncoder.

getOutputStream

public OutputStream getOutputStream()

Returns the OutputStream associated with this ImageEncoder.

Returns the current parameters as an instance of the ImageEncodeParam interface. Concrete implementations of this interface will return corresponding concrete implementations of the ImageEncodeParam interface. For example, a JPEGImageEncoder will return an instance of JPEGEncodeParam.

setParam

public void setParam(ImageEncodeParam param)

Sets the current parameters to an instance of the ImageEncodeParam interface. Concrete implementations of ImageEncoder may throw a RuntimeException if the params argument is not an instance of the appropriate subclass or subinterface. For example, a JPEGImageEncoder will expect param to be an instance of JPEGEncodeParam.
