Member Function Documentation

Alpha()

float ON_4fColor::Alpha

(

void

)

const

Alpha in ON_4fColor is OPACITY, not transparency as in ON_Color.

BlendTo()

void ON_4fColor::BlendTo	(	float	t,
		const ON_4fColor &	col,
		bool	clampAlpha = false
	)

Blend this color to 'col' using 't' from 0.0 to 1.0. Note: Does not clamp 't' or RGB result unless clampAlpha is true, in which case alpha is clamped.

Blue()

float ON_4fColor::Blue

(

void

)

const

Compare()

int ON_4fColor::Compare

(

const ON_4fColor &

other

)

const

Returns: < 0 if (this < other), 0 if (this == other), > 0 if (this > other).

FloatArray() [1/2]

float* ON_4fColor::FloatArray

(

void

)

Direct read/write access to array of four floats. NOTE: If you access the array beyond the 4th element, the function may crash Rhino.

FloatArray() [2/2]

const float* ON_4fColor::FloatArray

(

void

)

const

Direct read access to array of four floats. NOTE: If you access the array beyond the 4th element, the function may crash Rhino.
