imaging::Color::Color

(

const Color &

color

)

[inline]

Copy constructor.

imaging::Color::Color

(

GrayValue

value

)

[inline]

Initializes object from value. This function sets each channel to value.

imaging::Color::Color

(

float_t

value

)

[inline]

Initializes object from value. This function sets each channel to 255 * value.

imaging::Color::Color	(	unsigned char	r,
		unsigned char	g,
		unsigned char	b
	)			[inline]

Initializes object from red, green and blue values.

Member Function Documentation

imaging::Color::operator float_t

(

)

const [inline]

Type cast to float_t. The color value is converted to GrayValue and then divided by 255.
