Class Overview
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.
