public boolean getSerpentine()

Return the serpentine setting.

返回:

the current setting

另请参阅:

setSerpentine(boolean)

setColorDither

public void setColorDither(boolean colorDither)

Set whether to use a color dither.

参数:

colorDither - true to use a color dither

public int[] getMatrix()

Get the dither matrix.

返回:

the dither matrix

另请参阅:

setMatrix(int[])

setLevels

public void setLevels(int levels)

Set the number of dither levels.

参数:

levels - the number of levels

另请参阅:
