Description

A render node for a conic gradient.

Class initialization

new

:native-object

Create an object using a native object from elsewhere. See also Gnome::N::TopLevelSupportClass.

multi method new ( N-Object :$native-object! )

new-conicgradientnode

Creates a Gnome::Gsk4::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.

method new-conicgradientnode ( N-Object $bounds, N-Object $center, Num() $rotation, N-Object $color-stops, Int() $n-color-stops --> Gnome::Gsk4::ConicGradientNode \)

• $bounds; the bounds of the node

• $center; the center of the gradient

• $rotation; the rotation of the gradient in degrees.

• $color-stops; a pointer to an array of Gnome::Gsk4::N-ColorStop defining the gradient. The offsets of all color stops must be increasing. The first stop's offset must be >= 0 and the last stop's offset must be <= 1.

• $n-color-stops; the number of elements in $color-stops.

Methods

get-angle

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 - C<.get-rotation()>

method get-angle (--> Num )

Return value; the angle for the gradient.

get-center

Retrieves the center pointer for the gradient.

method get-center (--> N-Object )

Return value; the center point for the gradient.

get-color-stops

Retrieves the color stops in the gradient.

method get-color-stops ( Array[gsize] $n-stops --> N-Object )

• $n-stops; (transfer ownership: full) the number of color stops in the returned array.

Return value; the color stops in the gradient.

get-n-color-stops

Retrieves the number of color stops in the gradient.

method get-n-color-stops (--> Int )

Return value; the number of color stops.

get-rotation

Retrieves the rotation for the gradient in degrees.

method get-rotation (--> Num )

Return value; the rotation for the gradient.
