    static int
    argbAlpha(int argbSource, int argbIncoming)
    Mixes two colors scaled by the incoming color's alpha component.
    static int
    argbColor(float red, float green, float blue, float alpha)
    Converts a componentized color to an ARGB integer.
    static int
    argbHSLA(float hue, float saturation, float luminance, float alpha)
    Converts a hue-saturation-lightness-alpha color to an ARGB integer.
    static int
    argbMix(int argbSource, int argbIncoming, int scalar)
    Mixes two ARGB values linearly.
    static int
    argbMultiplyScaledIncomingAlpha(int argbSource, int argbIncoming)
    Multiply-blends two colors together, with the multiplication scaled by the incoming color's alpha component.
    static int

  • Method Details

    • argbColor

      public static int argbColor(float red, float green, float blue, float alpha)
      Converts a componentized color to an ARGB integer.
      Parameters:
      red - the red channel scalar (0 to 1).
      green - the green channel scalar (0 to 1).
      blue - the blue channel scalar (0 to 1).
      alpha - the alpha scalar (0 to 1).
      Returns:
      the resultant integer.

    • argbHSLA

      public static int argbHSLA(float hue, float saturation, float luminance, float alpha)
      Converts a hue-saturation-lightness-alpha color to an ARGB integer.
      Parameters:
      hue - the color hue (in radians).
      saturation - the saturation scalar (0 to 1).
      luminance - the luminance scalar (0 to 1).
      alpha - the alpha scalar (0 to 1).
      Returns:
      the resultant ARGB integer.

    • argbMix

      public static int argbMix(int argbSource, int argbIncoming, int scalar)
      Mixes two ARGB values linearly.
      Parameters:
      argbSource - the source ARGB color.
      argbIncoming - the destination ARGB color.
      scalar - transition scalar: 0 to 255. 128 is 50/50.
      Returns:
      the resultant ARGB color.

    • argbAlpha

      public static int argbAlpha(int argbSource, int argbIncoming)
      Mixes two colors scaled by the incoming color's alpha component.
      Parameters:
      argbSource - the source ARGB color.
      argbIncoming - the destination ARGB color.
      Returns:
      the resultant ARGB color.

    • argbAddScaledIncomingAlpha

      public static int argbAddScaledIncomingAlpha(int argbSource, int argbIncoming)
      Adds two colors, with the addition scaled by the incoming color's alpha component.
      Parameters:
      argbSource - the source ARGB color.
      argbIncoming - the destination ARGB color.
      Returns:
      the resultant ARGB color.

    • argbSubtractScaledIncomingAlpha

      public static int argbSubtractScaledIncomingAlpha(int argbSource, int argbIncoming)
      Subtracts the incoming color from the source, with the subtraction scaled by the incoming color's alpha component.
      Parameters:
      argbSource - the source ARGB color.
      argbIncoming - the destination ARGB color.
      Returns:
      the resultant ARGB color.

    • argbMultiplyScaledIncomingAlpha

      public static int argbMultiplyScaledIncomingAlpha(int argbSource, int argbIncoming)
      Multiply-blends two colors together, with the multiplication scaled by the incoming color's alpha component.
      Parameters:
      argbSource - the source ARGB color.
      argbIncoming - the destination ARGB color.
      Returns:
      the resultant ARGB color.
