Constructor

GskRadialGradientNodenew

Declaration [src]

GskRenderNode*
gsk_radial_gradient_node_new (
  const graphene_rect_t* bounds,
  const graphene_point_t* center,
  float hradius,
  float vradius,
  float start,
  float end,
  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 vertial orientation.

Parameters

`bounds`	`graphene_rect_t`
	The bounds of the node.
	The data is owned by the caller of the function.
`center`	`graphene_point_t`
	The center of the gradient.
	The data is owned by the caller of the function.
`hradius`	`float`
	The horizontal radius.
`vradius`	`float`
	The vertical radius.
`start`	`float`
	A percentage >= 0 that defines the start of the gradient around `center`.
`end`	`float`
	A percentage >= 0 that defines the end of the gradient around `center`.
`color_stops`	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`	`gsize`
	The number of elements in `color_stops`.

Return value

Returns:	`GskRadialGradientNode`
	A new `GskRenderNode`
	The caller of the function takes ownership of the data, and is responsible for freeing it.
