LightingColorFilter
extends ColorFilter

| ↳ | android.graphics.ColorFilter | |
| ↳ | android.graphics.LightingColorFilter | |
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.BThe result is pinned to the
[0..255] range for each channel.
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 | |
|---|---|
public LightingColorFilter (int mul,
int add)
