ColorMatrix class final
A 4x5 RGBA color matrix.
Values are stored row-major:
- row 0 transforms red
- row 1 transforms green
- row 2 transforms blue
- row 3 transforms alpha
Each row contains four coefficients plus one additive bias term.
Constructors
-
ColorMatrix(List<
double> values) - ColorMatrix.attenuation(double amount)
-
Returns an attenuation transform that scales RGB channels by
amount.factory - ColorMatrix.gain(double amount)
-
Returns a gain transform that scales RGB channels by
amount.factory - ColorMatrix.grayscale()
-
Returns a grayscale transform using sRGB luminance coefficients.
factory
- ColorMatrix.invert()
-
Returns an invert transform.
factory
- ColorMatrix.multiply(UvColor color)
-
Returns a multiply-style transform using
coloras the multiplier.factory - ColorMatrix.tint(UvColor tint, {double amount = 0.5})
-
Returns a tint transform that blends colors toward
tint.factory
