Constructor Detail

def : 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.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.

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.

[View source]
def color_stops : Enumerable(Gsk::ColorStop) #

Retrieves the color stops in the gradient.

See Object#hash(hasher)

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.
