Method Details

alter

public float alter(float color)

Takes a packed float color and produces a grayscale packed float color that this FloatFilter edited. Uses the luma calculation from SColor.lumaOfFloat(float) instead of the value calculation from SColor.valueOfFloat(float); luma tends to be more visually-accurate on modern monitors.

Specified by:

alter in class FloatFilter

Parameters:

color - a packed float color, as produced by Color.toFloatBits()

Returns:

a packed float color, as produced by Color.toFloatBits()
