Declaration [src]

GskRenderNode*
gsk_radial_gradient_node_new (
  const graphene_rect_t* bounds,

  float hradius,
  float vradius,
  float start,

  const GskColorStop* color_stops,
  gsize n_color_stops
)

Description [src]

Creates a GskRenderNode that draws a radial gradient.

The radial gradient starts around center. The size of the gradient is dictated by hradius in horizontal orientation and by vradius in vertical orientation.

Parameters

bounds

Type: graphene_rect_t

The bounds of the node.

The data is owned by the caller of the function.

center

Type: graphene_point_t

The center of the gradient.

The data is owned by the caller of the function.

hradius

Type: float

The horizontal radius.

vradius

Type: float

The vertical radius.

start

Type: float

A percentage >= 0 that defines the start of the gradient around center.

end

Type: float

A percentage >= 0 that defines the end of the gradient around center.

color_stops

Type: An array of GskColorStop

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.

The length of the array is specified in the n_color_stops argument.

The data is owned by the caller of the function.

n_color_stops

Type: gsize

The number of elements in color_stops.

Return value

Type: GskRadialGradientNode

A new GskRenderNode.

The caller of the function takes ownership of the data, and is responsible for freeing it.
