char * Laxkit::ColorBase::HexValue ( char * buffer )

virtual

buffer must be at least 10 characters long, or you will segfault.

Puts something like "#ff00abff" (without the quotes) in buffer. Returns buffer.

Referenced by Laxkit::ColorSliders::EditHex().

void Laxkit::ColorBase::SetCMYK	(	int	c,
		int	m,
		int	y,
		int	k,
		int	a = `-1`
	)

virtual

Set the channel when the value is >= 0.

Any values over max are clamped.

Any call to this function will set the color mode to LAX_COLOR_CMYK.

void Laxkit::ColorBase::SetCMYK	(	double	c,
		double	m,
		double	y,
		double	k,
		double	a = `-1`
	)

virtual

Values in [0..1].

void Laxkit::ColorBase::SetGray	(	int	g,
		int	a = `-1`
	)

virtual

Set the channel when the value is >= 0.

Any values over max are clamped.

Any call to this function will set the color mode to LAX_COLOR_CMYK.

Referenced by LaxInterfaces::ViewportWithStack::Event(), and LaxInterfaces::ViewerWindow::Event().

int Laxkit::ColorBase::SetHexValue ( const char * hex )

virtual

Return 0 for success, or 1 for parse error. hex must be something like "#00ff00ff", with 8 digits. The '#' is optional.

void Laxkit::ColorBase::SetRGB	(	int	r,
		int	g,
		int	b,
		int	a = `-1`
	)

virtual

Set the channel when the value is >= 0.

Any values over max are clamped.

Any call to this function will set the color mode to LAX_COLOR_RGB.

Referenced by LaxInterfaces::ViewportWithStack::Event(), and LaxInterfaces::ViewerWindow::Event().

void Laxkit::ColorBase::SetRGB	(	double	rr,
		double	gg,
		double	bb,
		double	aa = `-1`
	)

virtual

Values in [0..1].

void Laxkit::ColorBase::Updated ( )

virtual

Called when a value is changed through any of the various color setting functions.

Default is do nothing.
