Constructor Detail

Color

public Color(Color color)

Copy constructor

Parameters:

g - The green component of the colour (0.0 -> 1.0)

b - The blue component of the colour (0.0 -> 1.0)

Color

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

Create a 4 component colour

Parameters:

r - The red component of the colour (0.0 -> 1.0)

g - The green component of the colour (0.0 -> 1.0)

b - The blue component of the colour (0.0 -> 1.0)

a - The alpha component of the colour (0.0 -> 1.0)

Color

public Color(Color A,
             Color B,
             float delta)

Color

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

Create a 3 component colour

Parameters:

r - The red component of the colour (0 -> 255)

g - The green component of the colour (0 -> 255)

b - The blue component of the colour (0 -> 255)

Color

public Color(int r,

g - The green component of the colour (0 -> 255)

b - The blue component of the colour (0 -> 255)

a - The alpha component of the colour (0 -> 255)

Color

public Color(int value)

Create a colour from an evil integer packed 0xAARRGGBB. If AA is specified as zero then it will be interpreted as unspecified and hence a value of 255 will be recorded.

Parameters:

value - The value to interpret for the colour
