                 Rectangle transformedSpace)

Description copied from class: WholeImageFilter

Actually filter the pixels.

Specified by:

filterPixels in class WholeImageFilter

Parameters:

width - the image width

height - the image height

inPixels - the image pixels

transformedSpace - the output bounds

Returns:

the output pixels

toString

public String toString()

Overrides:

toString in class Object

getMetaData

public ImageFilterOps getMetaData()

Description copied from class: AbstractBufferedImageOp

Bambi filter metadata. This implementation always returns throws exception because this method can only be called if defined. This method should be overwritten if child filter is used within a Bambi app. The reason exception is throw rather than returning null is to help identify offending class which is much easier than tracing NPE.

Specified by:

getMetaData in interface ImageFilterOpSupport

Overrides:

getMetaData in class AbstractBufferedImageOp
