从类复制的说明: WholeImageFilter

Actually filter the pixels.

指定者:

filterPixels 在类中 WholeImageFilter

参数:

width - the image width

height - the image height

inPixels - the image pixels

transformedSpace - the output bounds

返回:

the output pixels

filterRGB

public int filterRGB(int x,
                     int y,
                     int rgb)

toString
```
public String toString()
```
覆盖:

toString 在类中 Object
