BufferedImageFilter JDK 1.6)

Methods

Hide/Show inherited methods

public Object clone () [Inherited From ImageFilter]

Clones this object.

public BufferedImageOp getBufferedImageOp ()

Returns the BufferedImageOp.

Returns the BufferedImageOp.
Returns: the operator of this BufferedImageFilter.

public ImageFilter getFilterInstance (ImageConsumer ic) [Inherited From ImageFilter]

Returns a unique instance of an ImageFilter object which will actually perform the filtering for the specified ImageConsumer.

public void imageComplete (int status) [Overrides ImageFilter]

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 retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.
Parameters:
- status - the status of image loading
Throws:
- ImagingOpException - if there was a problem calling the filter method of the BufferedImageOp associated with this instance.
See Also: ImageConsumer.imageComplete(int),

public void resendTopDownLeftRight (ImageProducer ip) [Inherited From ImageFilter]

Responds to a request for a TopDownLeftRight (TDLR) ordered resend of the pixel data from an ImageConsumer.

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.

Parameters:
- ip - the ImageProducer that is feeding this instance of the filter - also the ImageProducer that the request should be forwarded to if necessary
Throws:
- NullPointerException - if ip is null
See Also: ImageProducer.requestTopDownLeftRightResend(java.awt.image.ImageConsumer),

public void setColorModel (ColorModel model) [Overrides ImageFilter]

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

If model is null, this method clears the current ColorModel of this BufferedImageFilter.

Note: This method is intended to be called by the ImageProducer of the Image whose pixels are being filtered. Developers using this class to retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.
Parameters:
- model - the {@link ColorModel} to which to set the ColorModel of this BufferedImageFilter
See Also: ImageConsumer.setColorModel(java.awt.image.ColorModel),

public void setDimensions (int width, int height) [Overrides ImageFilter]

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

public void setHints (int hints) [Inherited From ImageFilter]

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

public void setPixels (int x, int y, int w, int h, ColorModel model, byte[] pixels, int off, int scansize) [Overrides ImageFilter]

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 retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.
Throws:
- IllegalArgumentException - if width or height are less than zero.
See Also: ImageConsumer.setPixels(int, int, int, int, ColorModel, byte[], int, int),

public void setPixels (int x, int y, int w, int h, ColorModel model, int[] pixels, int off, int scansize) [Overrides ImageFilter]

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 retrieve pixels from an image should avoid calling this method directly since that operation could result in problems with retrieving the requested pixels.
Throws:
- IllegalArgumentException - if width or height are less than zero.
See Also: ImageConsumer.setPixels(int, int, int, int, ColorModel, int[], int, int),

public void setProperties (Hashtable<Object, Object> props) [Inherited From ImageFilter]

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