Methods

Hide/Show inherited methods

public Object clone () [Inherited From ImageFilter]

Clones this object.

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) [Inherited From ImageFilter]

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

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

public void setColorModel (ColorModel model) [Inherited From ImageFilter]

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

public void setDimensions (int w, int h) [Inherited From ReplicateScaleFilter]

Override the dimensions of the source image and pass the dimensions of the new scaled size to the ImageConsumer.

public void setHints (int hints) [Overrides ImageFilter]

Detect if the data is being delivered with the necessary hints to allow the averaging algorithm to do its work.

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

Combine the components for the delivered byte pixels into the accumulation arrays and send on any averaged data for rows of pixels that are complete.

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

Combine the components for the delivered int pixels into the accumulation arrays and send on any averaged data for rows of pixels that are complete.

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

Passes along the properties from the source object after adding a property indicating the scale applied.

Passes along the properties from the source object after adding a property indicating the scale applied. This method invokes super.setProperties, which might result in additional properties being added.

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.
