public class LightingColorFilter
extends ColorFilter



A color filter that can be used to simulate simple lighting effects. A LightingColorFilter is defined by two parameters, one used to multiply the source color (called colorMultiply) and one used to add to the source color (called colorAdd). The alpha channel is left untouched by this color filter. Given a source color RGB, the resulting R'G'B' color is computed thusly:

 R' = R * colorMultiply.R + colorAdd.R
 G' = G * colorMultiply.G + colorAdd.G
 B' = B * colorMultiply.B + colorAdd.B
 

The result is pinned to the [0..255] range for each channel.

Summary

Public constructors

LightingColorFilter(int mul, int add)

Create a colorfilter that multiplies the RGB channels by one color, and then adds a second color.

Public methods

int getColorAdd()

Returns the RGB color that will be added to the source color when the color filter is applied.

int getColorMultiply()

Returns the RGB color used to multiply the source color when the color filter is applied.

Inherited methods

From class java.lang.Object

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
