Setters

None.

getAngle

conicGradientNodeGetAngle

Arguments

:: (HasCallStack, MonadIO m, IsConicGradientNode a)

=> a

node: a GskRenderNode for a conic gradient

-> m Float

Returns: the angle for the gradient

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 - conicGradientNodeGetRotation

Since: 4.2

getCenter

conicGradientNodeGetCenter

Arguments

:: (HasCallStack, MonadIO m, IsConicGradientNode a)

=> a

node: a GskRenderNode for a conic gradient

-> m Point

Returns: the center point for the gradient

Retrieves the center pointer for the gradient.

getColorStops

conicGradientNodeGetColorStops

Arguments

:: (HasCallStack, MonadIO m, IsConicGradientNode a)

=> a

node: a GskRenderNode for a conic gradient

-> m [ColorStop]

Returns: the color stops in the gradient

Retrieves the color stops in the gradient.

getNColorStops

conicGradientNodeGetNColorStops

Arguments

:: (HasCallStack, MonadIO m, IsConicGradientNode a)

=> a

node: a GskRenderNode for a conic gradient

-> m CSize

Returns: the number of color stops

Retrieves the number of color stops in the gradient.

getRotation

conicGradientNodeGetRotation

Arguments

:: (HasCallStack, MonadIO m, IsConicGradientNode a)

=> a

node: a GskRenderNode for a conic gradient

-> m Float

Returns: the rotation for the gradient

Retrieves the rotation for the gradient in degrees.

new

conicGradientNodeNew

Arguments

:: (HasCallStack, MonadIO m)

=> Rect

bounds: the bounds of the node

-> Point

center: the center of the gradient

-> Float

rotation: the rotation of the gradient in degrees

-> [ColorStop]

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.

-> m ConicGradientNode

Returns: A new GskRenderNode

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.
