Constructor Detail

def self.new(bounds : Graphene::Rect, center : Graphene::Point, rotation : Float32, color_stops : Enumerable(Gsk::ColorStop)) : self #

Creates a Gsk::RenderNode that draws a conic gradient.

The conic gradient starts around @center in the direction of @rotation. A rotation of 0 means that the gradient points up. Color stops are then added clockwise.


def self.new #

Initialize a new ConicGradientNode.


Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def angle : Float32 #

Retrieves the angle for the gradient in radians, normalized in [0, 2 * PI].

The angle is starting at the top and going clockwise, as expressed in the css specification:

angle = 90 - gsk_conic_gradient_node_get_rotation()

def center : Graphene::Point #

Retrieves the center pointer for the gradient.


def color_stops : Enumerable(Gsk::ColorStop) #

Retrieves the color stops in the gradient.


def n_color_stops : UInt64 #

Retrieves the number of color stops in the gradient.


def rotation : Float32 #

Retrieves the rotation for the gradient in degrees.
