 public Object clone() 
{
        try {
            return super.clone();
        } catch (CloneNotSupportedException e) {
            // this shouldn't happen, since we are Cloneable
            throw new InternalError();
        }
}

Clones this object.

 public ImageFilter getFilterInstance(ImageConsumer ic) 
{
        ImageFilter instance = (ImageFilter) clone();
        instance.consumer = ic;
        return instance;
}

Returns a unique instance of an ImageFilter object which will actually perform the filtering for the specified ImageConsumer. The default implementation just clones this object.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

 public  void imageComplete(int status) 
{
        consumer.imageComplete(status);
}

Filters the information provided in the imageComplete method of the ImageConsumer interface.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

 public  void resendTopDownLeftRight(ImageProducer ip) 
{
        ip.requestTopDownLeftRightResend(this);
}

Responds to a request for a TopDownLeftRight (TDLR) ordered resend of the pixel data from an ImageConsumer. When an ImageConsumer being fed by an instance of this ImageFilter requests a resend of the data in TDLR order, the FilteredImageSource invokes this method of the ImageFilter.

An ImageFilter subclass might override this method or not, depending on if and how it can send data in TDLR order. Three possibilities exist:

• Do not override this method. This makes the subclass use the default implementation, which is to forward the request to the indicated ImageProducer using this filter as the requesting ImageConsumer. This behavior is appropriate if the filter can determine that it will forward the pixels in TDLR order if its upstream producer object sends them in TDLR order.
• Override the method to simply send the data. This is appropriate if the filter can handle the request itself — for example, if the generated pixels have been saved in some sort of buffer.
• Override the method to do nothing. This is appropriate if the filter cannot produce filtered data in TDLR order.

 public  void setColorModel(ColorModel model) 
{
        consumer.setColorModel(model);
}

Filter the information provided in the setColorModel method of the ImageConsumer interface.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

 public  void setDimensions(int width,
    int height) 
{
        consumer.setDimensions(width, height);
}

Filters the information provided in the setDimensions method of the ImageConsumer interface.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

 public  void setHints(int hints) 
{
        consumer.setHints(hints);
}

Filters the information provided in the setHints method of the ImageConsumer interface.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

 public  void setPixels(int x,
    int y,
    int w,
    int h,
    ColorModel model,
    byte[] pixels,
    int off,
    int scansize) 
{
        consumer.setPixels(x, y, w, h, model, pixels, off, scansize);
}

Filters the information provided in the setPixels method of the ImageConsumer interface which takes an array of bytes.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

 public  void setPixels(int x,
    int y,
    int w,
    int h,
    ColorModel model,
    int[] pixels,
    int off,
    int scansize) 
{
        consumer.setPixels(x, y, w, h, model, pixels, off, scansize);
}

Filters the information provided in the setPixels method of the ImageConsumer interface which takes an array of integers.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.

 public  void setProperties(Hashtable props) 
{
        Hashtable< Object,Object > p = (Hashtable< Object,Object >)props.clone();
        Object o = p.get("filters");
        if (o == null) {
            p.put("filters", toString());
        } else if (o instanceof String) {
            p.put("filters", ((String) o)+toString());
        }
        consumer.setProperties(p);
}

Passes the properties from the source object along after adding a property indicating the stream of filters it has been run through.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to filter pixels from an image should avoid calling this method directly since that operation could interfere with the filtering operation.
