ImageFilter

extends Object

implements ImageConsumer
This class implements a filter for the set of interface methods that
are used to deliver data from an ImageProducer to an ImageConsumer.
It is meant to be used in conjunction with a FilteredImageSource
object to produce filtered versions of existing images. It is a
base class that provides the calls needed to implement a "Null filter"
which has no effect on the data being passed through. Filters should
subclass this class and override the methods which deal with the
data that needs to be filtered and modify it as necessary.

consumer
-
The consumer of the particular image data stream that this
instance of the ImageFilter is filtering data for.
-
ImageFilter()
-
-
getFilterInstance(ImageConsumer)
-
Return a unique instance of an ImageFilter object which will
actually perform the filtering for the specified ImageConsumer.
-
imageComplete(int)
-
Filter the information provided in the imageComplete method of
the ImageConsumer interface.
-
setColorModel(ColorModel)
-
Filter the information provided in the setColorModel method
of the ImageConsumer interface.
-
setDimensions(int, int)
-
Filter the information provided in the setDimensions method
of the ImageConsumer interface.
-
setHints(int)
-
Filter the information provided in the setHints method
of the ImageConsumer interface.
-
setPixels(int, int, int, int, ColorModel, byte[], int, int)
-
Filter the information provided in the setPixels method of the
ImageConsumer interface which takes an array of bytes.
-
setPixels(int, int, int, int, ColorModel, int[], int, int)
-
Filter the information provided in the setPixels method of the
ImageConsumer interface which takes an array of integers.
-
setProperties(Hashtable)
-
Pass the properties from the source object along after adding a
property indicating the stream of filters it has been run through.
consumer
protected ImageConsumer consumer
-
The consumer of the particular image data stream that this
instance of the ImageFilter is filtering data for. It is not
initialized during the constructor, but rather during the
getFilterInstance() method call when the FilteredImageSource
is creating a unique instance of this object for a particular
image data stream.

public ImageFilter()
getFilterInstance
public ImageFilter getFilterInstance(ImageConsumer ic)
-
Return a unique instance of an ImageFilter object which will
actually perform the filtering for the specified ImageConsumer.
The default implementation just clones this object.
setDimensions
public void setDimensions(int width,
int height)
-
Filter the information provided in the setDimensions method
of the ImageConsumer interface.

property indicating the stream of filters it has been run through.
setColorModel
public void setColorModel(ColorModel model)
-
Filter the information provided in the setColorModel method
of the ImageConsumer interface.
