Constructor Detail

public FlipFilter(int operation)

Construct a FlipFilter.

Parameters:

operation - the filter operation

Method Detail

filter

public BufferedImage filter(BufferedImage src,
                   BufferedImage dst)

Specified by:

filter in interface BufferedImageOp

Overrides:

filter in class AbstractBufferedImageOp

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
