public DiffusionFilter()

Construct a DiffusionFilter

Method Detail

setSerpentine

public void setSerpentine(boolean serpentine)

Set whether to use a serpentine pattern for return or not. This can reduce 'avalanche' artifacts in the output.

Parameters:

serpentine - true to use serpentine pattern

getSerpentine

public boolean getSerpentine()

Return the serpentine setting

Returns:

the current setting

setColorDither

public void setColorDither(boolean colorDither)

getColorDither

public boolean getColorDither()

setMatrix

public void setMatrix(int[] matrix)

getMatrix

public int[] getMatrix()

setLevels

public void setLevels(int levels)

getLevels

public int getLevels()
