Constructor Detail

Color

public Color(int r,
             int g,
             int b,
             int a)

Creates an sRGB color with the specified red, green, blue, and alpha values in the range (0 - 255).

Parameters:

r - the red component.

g - the green component.

b - the blue component.

a - the alpha component.

Color

public Color(int rgb)

Creates an sRGB color from the specified RGB color value.

Parameters:

rgb - The value of the RGB color. Bits 24-31 are alpha, 16-23 are red, 8-15 are green, 0-7 are blue.

Color

public Color(int r,
             int g,
             int b)
