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()
