Constructor Details

ConicGradientNode

public ConicGradientNode(MemorySegment address)

Create a ConicGradientNode proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

ConicGradientNode

public ConicGradientNode(Rect bounds,
 Point center,
 float rotation,
 @Nullable ColorStop @Nullable [] colorStops)

Creates a GskRenderNode 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.

Parameters:

bounds - the bounds of the node

center - the center of the gradient

rotation - the rotation of the gradient in degrees

colorStops - a pointer to an array of GskColorStop 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.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ConicGradientNode class

Returns:

the GType

asParent

protected ConicGradientNode asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class RenderNode

getAngle

public float getAngle()

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()

Returns:

the angle for the gradient

Since:

4.2

getCenter

public Point getCenter()

Retrieves the center pointer for the gradient.

Returns:

the center point for the gradient

getColorStops

public ColorStop[] getColorStops()

Retrieves the color stops in the gradient.

Returns:

the color stops in the gradient

getNColorStops

public long getNColorStops()

Retrieves the number of color stops in the gradient.

Returns:

the number of color stops

getRotation

public float getRotation()

Retrieves the rotation for the gradient in degrees.

Returns:

the rotation for the gradient
