public class GrayFilter
extends RGBImageFilter

An image filter that "disables" an image by turning it into a grayscale image, and brightening the pixels in the image. Used by buttons to create an image for a disabled button.

Constructor Detail

### GrayFilter

    public GrayFilter(boolean b,
                      int p)

  Constructs a GrayFilter object that filters a color image to a grayscale image. Used by buttons to create disabled ("grayed out") button images.

Parameters:
  `b` - a boolean -- true if the pixels should be brightened
  `p` - an int in the range 0..100 that determines the percentage of gray, where 100 is the darkest gray, and 0 is the lightest

Method Detail

### createDisabledImage

    public static Image createDisabledImage(Image i)

  Creates a disabled image

### filterRGB

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

  Overrides `RGBImageFilter.filterRGB`.

  Specified by:
    `filterRGB` in class `RGBImageFilter`
  Parameters:
    `rgb` - the integer pixel representation in the default RGB color model
  Returns:
    a filtered pixel in the default RGB color model.
  See Also:
    `ColorModel.getRGBdefault()`, `RGBImageFilter.filterRGBPixels(int, int, int, int, int[], int, int)`
