create

public static javax.media.jai.RenderedOp create(RenderedImage source0,
                                                javax.media.jai.KernelJAI kernel,
                                                int threshold,
                                                RenderingHints hints)

Performs kernel-based threshold blur on an image.

Parameters:

source0 - RenderedImage source 0.

kernel - The convolution kernel.

threshold - The limit to use.

hints - The RenderingHints to use. May be null .

Returns:

The RenderedOp destination.

Throws:

IllegalArgumentException - if source0 is null.

IllegalArgumentException - if kernel is null.
