javax.swing.GrayFilter
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.

->gray-filterclj
(->gray-filter b p)Constructor.
Constructs a GrayFilter object that filters a color image to a grayscale image. Used by buttons to create disabled ("grayed out") button images.
b - a boolean -- true if the pixels should be brightened - boolean
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 - int

(filter-rgb this x y rgb)Overrides RGBImageFilter.filterRGB.
x - the X coordinate of the pixel - int
y - the Y coordinate of the pixel - int
rgb - the integer pixel representation in the default RGB color model - int
returns: a filtered pixel in the default RGB color model. - int
