Detailed Description

A class representing the settings for linear-gradient color effect.

Example:

LinearGradient()
   .Angle(45)
   .Stop(Color::Red, 0.0)
   .Stop(Color::Green, 0.5)
   .Stop(Color::Blue, 1.0);

There are also shorthand constructors:

LinearGradient(Color::Red, Color::Blue);
LinearGradient(45, Color::Red, Color::Blue);

Examples

examples/component/input_style.cpp, examples/component/linear_gradient_gallery.cpp, examples/dom/linear_gradient.cpp, and examples/dom/style_color.cpp.

Constructor & Destructor Documentation

LinearGradient() [1/3]

LinearGradient ( )

default

Build the "empty" gradient. This is often followed by calls to LinearGradient::Angle() and LinearGradient::Stop(). Example:

auto gradient =
 LinearGradient()
  .Angle(45)
  .Stop(Color::Red, 0.0)
  .Stop(Color::Green, 0.5)
  .Stop(Color::Blue, 1.0);;

LinearGradient() [2/3]

LinearGradient	(	Color	begin,
		Color	end
	)

Build a gradient with two colors.

Parameters

begin	The color at the beginning of the gradient.
end	The color at the end of the gradient.

Definition at line 195 of file linear_gradient.cpp.

LinearGradient() [3/3]

LinearGradient	(	float	a,
		Color	begin,
		Color	end
	)

Build a gradient with two colors and an angle.

Parameters

a	The angle of the gradient.
begin	The color at the beginning of the gradient.
end	The color at the end of the gradient.

Definition at line 203 of file linear_gradient.cpp.

Member Function Documentation

Angle()

LinearGradient & Angle

(

float

a

)

Set the angle of the gradient.

Parameters

a	The angle of the gradient.

Returns

The gradient.

Definition at line 212 of file linear_gradient.cpp.

Stop() [1/2]

LinearGradient & Stop	(	Color	c,
		float	p
	)

Add a color stop to the gradient.

Parameters

c	The color of the stop.
p	The position of the stop.

Returns

The gradient.

Definition at line 221 of file linear_gradient.cpp.

Stop() [2/2]

LinearGradient & Stop

(

Color

c

)

Add a color stop to the gradient.

Parameters

c	The color of the stop.

Returns

The gradient.

Note

The position of the stop is interpolated from nearby stops.

Definition at line 231 of file linear_gradient.cpp.
