filter

public BufferedImage filter(BufferedImage src,
                   BufferedImage dst)

Specified by:

filter in interface BufferedImageOp

Overrides:

filter in class TransformFilter

transformInverse

protected void transformInverse(int x,
                    int y,
                    float[] out)

Description copied from class: TransformFilter

Inverse transform a point. This method needs to be overriden by all subclasses.

Specified by:

transformInverse in class TransformFilter

Parameters:

x - the X position of the pixel in the output image

y - the Y position of the pixel in the output image

out - the position of the pixel in the input image

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
