方法详细资料

getRGB

public int[] getRGB(BufferedImage image,
           int x,
           int y,
           int width,
           int height,
           int[] pixels)

A convenience method for getting ARGB pixels from an image. This tries to avoid the performance penalty of BufferedImage.getRGB unmanaging the image.

init

public void init(int[] pixels,
        int width,
        int height,
        int edgeAction,
        boolean alpha)

evaluate

public float evaluate(float x,
             float y)

指定者:

evaluate 在接口中 Function2D

setEdgeAction

public void setEdgeAction(int edgeAction)

getEdgeAction

public int getEdgeAction()

getWidth

public int getWidth()

getHeight

public int getHeight()

getPixels

public int[] getPixels()
