LightingColorFilter
open class LightingColorFilter : ColorFilter
| kotlin.Any | ||

| ↳ | 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.B
[0..255] range for each channel.

Public constructors
LightingColorFilter
LightingColorFilter(
mul: Int,
add: Int)
Create a colorfilter that multiplies the RGB channels by one color, and then adds a second color. The alpha components of the mul and add arguments are ignored.
Public methods
getColorAdd
open fun getColorAdd(): Int
Returns the RGB color that will be added to the source color when the color filter is applied.
getColorMultiply
open fun getColorMultiply(): Int
Returns the RGB color used to multiply the source color when the color filter is applied.
