LayerColorScaleBias

LayerColorScaleBias

class LayerColorScaleBias(var scale: Vector4, var bias: Vector4)
Controls color adjustment for rendering layers.
LayerColorScaleBias provides a way to adjust the color output of a layer by applying scale and bias transformations to the RGBA color channels. This allows for effects like tinting, brightness adjustment, contrast modification, and transparency control.
The color transformation is applied using the formula: finalColor = (sourceColor * scale) + bias
Example usage:
// Create a layer config with 50% opacity
val halfTransparent = LayerColorScaleBias(
    scale = Vector4(1.0f, 1.0f, 1.0f, 0.5f),  // Keep RGB the same, reduce alpha to 50%
    bias = Vector4(0.0f, 0.0f, 0.0f, 0.0f)    // No bias
)

// Create a layer config with a blue tint
val blueTint = LayerColorScaleBias(
    scale = Vector4(0.8f, 0.8f, 1.0f, 1.0f),  // Reduce red and green, keep blue and alpha
    bias = Vector4(0.0f, 0.0f, 0.2f, 0.0f)    // Add some blue
)
